  • Style of Invited paper
  • Style of Research Article
  • Style of Research note

Format

Full length article should be suitably divided into the following sub-sections; ABSTRACT, Key words, INTRODUCTION, MATERIALS AND METHODS, RESULTS AND DISCUSSION and REFERENCES. The heading, introduction need not be mentioned in the text.

Title

The title of article should be informative but concise and should not contain abbreviations. It should indicate the content of the article essential for key word indexing and information retrieval. It should be set in small and bold letters. A good title briefly identifies the subject, indicates the purpose of study and introduces key terms and concepts. Title should not be started with the waste words like 'a study of', 'effect of', 'influence of' , 'some observations on', 'a note of' etc. The title should indicate preferably English name or most popular common name of the crops or organisms studied, wherever relevant. Scientific name can be given in abstract and introduction. Authority for such a name should be given at first mention in the text. A short title should be given for running headlines and should cover the main theme of the article.

Author(s) name(s) and affiliations

The name(s) of the author(s) should be given in small letters with sentence case separated by 'comma' or by 'and'. Institute name where the research was carried out should be given in italics. If authors are of different institutes, these can be mentioned by allotting number like 1, 2 or 3 as superscript over the name of author. The affiliation of such author may be given below of the corresponding author email address. Sometimes authors retire and change frequently and wish to give their current address, this should be given as foot note. Email address of main author or corresponding author should be given at the bottom.

Abstract

The abstract should contain at least one sentence on each of the following: objective of investigation (hypothesis, purpose, collection, result and conclusions). Give complete scientific name for plants or other organisms and full name of any symbol or abbreviations used. There is a need to mention place, name and priod of study in abstract. Emphasis should be given to highlight the results and the conclusion of the study. It should not exceed a total length of 200-250 words. Abstract should not have the words like 'will be explained or will be discussed'.

Key words

(5 6) should be given at the end of the abstract and should be arranged alphabetically. Each key word should be started with capital letter and separated by comma ( , ) from other words.

Introduction

Introduction should be brief and to the point, cover the problem and should justify the work or the hypothesis on which it is based. In introduction, a detail review is not necessary. However, to orient readers, important references about previous concepts and research should be given. It should briefly state the currently available information and should identify the research gap that is expected to be abridged through this investigation. Give preference to recent references from standard research publication unless it is of historical importance or a landmark in that field.

Materials and Methods

This part should begin with information relating to period/season/year and place of study, climate or weather conditions, soil type etc. Treatment details along with techniques and experimental design, replications, plot size etc. should be clearly indicated. Use of symbols for treatments may be avoided and an abbreviation should be fully explained at its first mention. Crop variety, methodology for application and common cultivation practices should be mentioned. Known methods may be just indicated giving reference but new techniques developed and followed should be described in detail. Methods can be divided into suitable sub-headings, typed in bold at first level and in italics at second level, if necessary.

Results and Discussion

Results may be reported and discussed together to avoid duplication. Do not mention and recite the data in the text as such given in the table. Instead interpret it suitably by indicating in terms of per cent, absolute change or any other derivations. Relate results to the objectives with suitable interpretation of the references given in the introduction. If results differ from the previous study, suitable interpretation and justification should be given. Repeated use of statements like 'our results are in agreement’ or ‘similar results were reported’ 'should be avoided. At the end of results and discussion, conclusion of the study should be given in 2-3 sentences along with suggestion for further study, if any. All statistical comparisons among treatments may be made at P=0.05 level of probability.

Acknowledgement

The authors may place on record the help and cooperation or any financial help received from any source, person or organization for this study. This should be very brief.

References

Only relevant and recent references of standard work should be quoted. Preference should be given to quote references of journals over proceedings or reports. In general, not more than 15 references should be quoted in full paper and 5 in short communication. However, in review article, emphasis should be given to quote more references with each valid statement/findings in the text. There is no need to give references for standard procedures of soil and plant analysis, and for routine statistical analysis in practice, only the methodology may be indicated. As a thumb rule, all the references quoted in the text must appear at the end of the article and vice-verse. It has been decided to use full name of the journal after the year 2011 onwards. Therefore, references should include names of all authors, year, full title of the article quoted, full name of the journal in italics (no abbreviations), volume number (in Bold), issue number (in brackets) and pages. For books, monographs, theses etc. full title in italics, publisher or university name, volume no., if any, and relevant page range or total no. of pages should be given. The list of references should be arranged alphabetically on author's names and chronologically per author. Author name should be started with surname and initial letter with capital letter. There is no need to separate author's initials by full stop but it should be given in capital letters without gap. Each author name should be separated by comma (,) and last author name by ‘and’.

Length

Full length manuscript should not exceed 4500 words including space required for figures, tables and list of references. Research note can be up to 2500 words, with not more than 2 figures or tables. One season/year data should invariably be presented as research notes only.

Units, abbreviations and nomenclature

For physical units, unit names and symbols, the SI system should be employed. Biological names should be given according to the latest international nomenclature. Upon its first use in the title, abstract and text, the common name of a weed should be followed by the scientific name (genus, species and authority) in parentheses. If no common name exists in English, the scientific name should be used only. At the first mention of an herbicide or other chemical substance, give its generic name only. Trade names should not be used. Biological and zoological names, gene designations and gene symbols should be italicized. Yield data should be reported in kg/ha or t/ha. All such letters such as viz., et al., in situ, ex situ, Rabi, Kharif, i.e., etc. should be italicized.

Tables and figures

Tables and figures should be concise and limited to the necessary minimum. We encourage the authors to set tables and figures at the appropriate places in the article but if it is not possible, the same may be given separately. The title should fully describe the contents of the table and explain any symbol or abbreviations used in it. The standard abbreviations of the units of different parameters should be indicated in parentheses. Vertical lines should not be given in the tables and horizontal lines should be used to separate parameters and end of the table.

Figures may be preferred in place of table. In no case the same data should be presented by both tables and figures. While presenting data through line graphs, vertical bars, cylinders, pie charts etc, the same should be preferred with black lines or bars having different clear symbols and shades. The graphs chosen with colours reproduce poorly and should not be given unless it became necessary.

Some useful tips

Avoid numerals and abbreviations at the beginning of a sentence. Don't use superscript for per hectare, ton or meter (kg ha-1 or t ha-1) instead use kg/ha or g/m2, t/ha, mg/g, ml/l etc. Prefer to mention yield data in t/ha only. If it becomes necessary, give yield in kg/ha but not in quintal. Don't use lakh, crores or arabs in text, instead give such figures in million. Only standard abbreviations should be used and invariably be explained at first mention. Avoid use of self-made abbreviations like iso., buta., rizo., etc. Don't use first letter capital for names of plant protection chemicals but it should be used for trade names. Use of treatment symbols like T1 T2 T3 etc. should be avoided. All weights and measurements must be in SI or metric units. Use % after double digit figures, not per cent, for example 10% not 10 per cent. In a series of range of measurement, mention the units only at the end, e.g. 3,4,5 kg/ha instead of 3 kg/ha, 4 kg/ha and 5 kg/ha. Nutrient doses as well as concentration in soil and plant should be given in elemental form only, i.e. P and K should not be given as P2O5 K2O. A variety may be mentioned within single quotes in italic such as 'Pusa Basmai', 'Kufri Sinduri' etc. Statistical data should be given in LSD (P=0.05) instead CD (P=0.05).

Authors are requested to see the recent issue of the journal to prepare the manuscript as per the journal's format.

Peer Review Policy

All published articles in Indian Journal of Weed Science (IJWS) are subjected to rigorous peer review processes based on initial editor screening and anonymized refereeing by two referees. The ultimate purpose of peer review is to sustain the originality and quality of research work and filtration of poor quality and plagiarized articles. Peer review assures research quality.

Paper Publication Process –

  • Manuscripts are received online in the editorial office with the certificate that MS has not been sent for consideration in any other journals for consideration.
  • Manuscripts are checked by office for its style and pattern and for plagiarism. If plagiarism is more than 20%, it is not considered and sent back to author for revision and re-submission.
  • If MS is found fit at Editorial office in context to plagiarism and style and pattern, it is sent to Chief Editor for further processing.
  • If chief Editor find the MS suitable for consideration, he shall suggest two name of referees as reviewers either from editorial board or from other institutions of concern discipline for reviewing the MS.
  • Editorial Office shall send the MS for double blind review to the reviewers suggested by Chief Editor.
  • Comments of double -blind reviewers will be sent to corresponding author without disclosing the identity of the reviewers to address the comments and re-submission of MS.
  • In case, one reviewer rejects while other accept the MS, it is sent to third reviewer suggested by Chief Editor.
  • Revised MS is again sent to reviewers to see whether their comments are addressed suitably.
  • On agreeing by the reviewers, the MS is again sent to Chief Editors with comments of reviewers and reply of author to take the final decision.
  • The final decision of Chief Editor is communicated to authors.

Peer Review Policy

The practice of peer review is to ensure that only good science is published. It is an objective process at the heart of good scholarly publishing and is carried out by all reputable scientific journals. Our reviewers therefore play a vital role in maintaining the high standards of the (Indian Journal of Weed Science) Journal of Management and Research and all manuscripts are peer reviewed following the procedure outlined below.

Initial manuscript evaluation

The Editors first evaluate all manuscripts. In some circumstances it is entirely feasible for an exceptional manuscript to be accepted at this stage. Those rejected at this stage are insufficiently original, have serious scientific flaws, have poor grammar or English language, or are outside the aims and scope of the journal. Those that meet the minimum criteria are passed on to experts for review.

Authors of manuscripts rejected at this stage will be informed within 2 weeks of receipt.

Type of Peer Review

The (Indian Journal of Weed Science) employs double blind review, where the reviewer remains anonymous to the authors throughout the process.

How the reviewer is selected

Reviewers are matched to the paper according to their expertise. Our reviewer database contains reviewer contact details together with their subject areas of interest, and this is constantly being updated.

Reviewer reports

Reviewers are asked to evaluate whether the manuscript:

  • Is original
  • Is methodologically sound
  • Follows appropriate ethical guidelines
  • Has results which are clearly presented and support the conclusions
  • Correctly references previous relevant work

Reviewers are not expected to correct or copyedit manuscripts. Language correction is not part of the peer review process. Reviewers are requested to refrain from giving their personal opinion in the "Reviewer blind comments to Author" section of their review on whether or not the paper should be published. Personal opinions can be expressed in the "Reviewer confidential comments to Editor" section.

How long does the peer review process take?

Typically the manuscript will be reviewed within 2-8 weeks. Should the reviewers' reports contradict one another or a report is unnecessarily delayed a further expert opinion will be sought. Revised manuscripts are usually returned to the Editors within 3 weeks and the Editors may request further advice from the reviewers at this time. The Editors may request more than one revision of a manuscript.

Final report

A final decision to accept or reject the manuscript will be sent to the author along with any recommendations made by the reviewers, and may include verbatim comments by the reviewers.
Chief Editor's Decision is final
Reviewers advise the Editors, who are responsible for the final decision to accept or reject the article.

Special Issues / Conference Proceedings

Special issues and/or conference proceedings may have different peer review procedures involving, for example, Guest Editors, conference organizers or scientific committees. Authors contributing to these projects may receive full details of the peer review process on request from the editorial office.

Becoming a Reviewer for the (Indian Journal of Weed Science)

If you are not currently a reviewer for the (Indian Journal of Weed Science) but would like to be considered as a reviewer for this Journal, please contact the editorial office by e-mail at (editorisws@gmail.com), and provide your contact details. If your request is approved and you are added to the online reviewer database you will receive a confirmatory email, asking you to add details on your field of expertise, in the format of subject classifications.

Abstract:

Integrated weed management (IWM) is a science-based decision-making process that coordinates the use of macro and micro-environment information, weed biology and ecology, and all available technologies to control weeds by the most economical and ecologically viable methods. The concept of IWM is not new and many advances have been made in recent years in India. The IWM research carried out in India during the last 20 years is reviewed in this paper. Limited ecological studies were carried out on certain problematic weeds. Majority of the research in India on IWM was herbicide-based. Economic analysis revealed that herbicides use in combination with hand weeding was most economical. Weeds are dynamic and it is required to redesign the strategies from time to time for the successful management of ever increasing problem of weeds. IWM research in India must broaden beyond herbicide-centred weed management. Future IWM research in India must focus on decision-making processes, weed biology and ecology, environmentally and economically viable components of IWM practices in cropping systems, herbicide resistance, environmental issues related to transgenic plants, and potential benefits of weeds.

Abstract:

Impact of aryloxyphenoxypropionate herbicides used since 1998 to control Phalaris minor in Haryana was evaluated during 2008-09 and 2009-10 under screen house conditions.  Most of the populations evaluated against fenoxaprop-P-ethyl and clodinafop-propargyl exhibited either a high or a medium level of resistance in 2008-09. Similar results were obtained for clodinafop in 2009-10. Some of the populations were also susceptible to fenoxaprop (120 g/ha) indicating segregation of alleles for the resistant and susceptible traits as homozygous as well as heterozygous individuals in the progeny.  Most of the populations were susceptible to phenylpyrazolin derivative- pinoxaden used at 25, 50 and 100 g/ha. However, a fraction of the populations exhibited insensitivity towards pinoxaden without any prior history of exposure. The data are supported by GR50 values, ion efflux tests and pigment retention tests. Selection pressure exerted by the aryloxyphenoxypropionate and/or urea herbicides could possibly be responsible for such an effect. Bioassay methods need to be developed for location specific identification of the resistance to herbicides and their early management.

Abstract:

Pot studies were carried out at Agronomy Research Farm of CCSHAU, Hisar during the rabi seasons of 2005-06, 2006-07 and 2007-08 using isoproturon resistant, susceptible and pristine populations of Phalaris minor. Ten herbicides (isoproturon, chlorotoluron, sulfosulfuron, clodinafop-propargyl, fenoxaprop-P-ethyl, quizalofop-ethyl, premix of mesosulfuron-methyl+iodosulfuron-methyl-sodium, sulfosulfuron+metsulfuron-methyl, pinoxaden and tank mix of pinoxaden+carfentrazone-ethyl) were applied at two growth stages (4 leaf and tillering) of five P. minor populations [J-35 (Jind), F-42 (Fatehabad), K-15 (Karnal), H-2 (Hisar) from Haryana and B-6 (Bihar)] using three application rates by a knapsack sprayer fitted with flat fan multi nozzle boom delivering 500 l water/ha.  The pots were arranged in a CRD design with three replicated earthen pots for each herbicide treatment and populations.  Plant height, weed mortality and fresh/dry weight were recorded to evaluate herbicides effect on P. minor populations. When combined data were analyzed, no significant interaction of weed stage, populations and herbicides was observed for per cent mortality and dry weight, whereas highly significant effect of weed stage, populations and herbicides was recorded.  There was significant interaction of populations and herbicides for mortality data.  Significant interaction for stage, dose and herbicides was recorded when data for each population at two growth stages were subjected to ANOVA, which shows large variations among populations to different herbicides.  P. minor populations, J-35 and K-15 had significantly lower mortality and higher dry weight, data averaged over herbicides, compared to B-6 and H-2, whereas F-42 was intermediate in mortality and accumulated higher dry weight compared to B-6 and H-2. Among the herbicides, lowest mortality was recorded with clodinafop and isoproturon followed by fenoxaprop and quizalofop, whereas highest mortality was recorded with pinoxaden tank mixed with carfentrazone and its alone application followed by chlorotoluron and mesosulfuron+iodosulfuron. Sulfosulfuron alone and premix with metsulfuron had lower mortality compared to pinoxaden±carfentrazone and chlorotoluron.  Similar results were recorded for dry weight also.  Delayed application from 4 leaf to tillering stage lowered the mortality of sulfosulfuron±metsulfuron, mesosulfuron+iodosulfuron, isoproturon and chlorotoluron.  The GR50 (growth reduction by 50%) of herbicides increased with stage of herbicide application; increase was more in isoproturon and clodinafop compared to other herbicides. Populations, K-15 and J-35 had resistance factor (Rf) of 10.85 and 4.91 for isoproturon and 1.70 and 1.25 for clodinafop, respectively, when applied at tillering stage compared to H-2 population. Some variations were also observed in GR50 with other herbicides, but not reflected in dry weight. The study indicated ensuing problems with clodinafop, fenoxaprop and even sulfosulfuron, but there was no loss of efficacy with pinoxaden±carfentrazone or chlorotoluron.

Abstract:

Carfentrazone-ethyl 20%+sulfosulfuron 25% WDG (Premix) was evaluated against mixed weed flora in wheat during rabi seasons of 2008-09 and 2009-10 at the Research Farm of Department of Agronomy, Punjab Agricultural University, Ludhiana. The experimental field was heavily infested with Phalaris minor and broadleaf weeds. Among the herbicidal treatments, post-emergence application (30-35 DAS) of premix herbicide i. e. carfentrazone + sulfosulfuron at 36, 45 and 54 g/ha either with 625 ml or 750 ml/ha of surfactants performed at par with the recommended herbicides i. e. Leader 75 WG (sulfosulfuron) at 25 g/ha and Total 75 WG (sulfosulfuron + metsulfuron) with respect to reduction in dry matter accumulation by P. minor as well as broadleaf weeds and production of grain yield of wheat. The bioefficacy of carfentrazone+sulfosulfuron at 45 g/ha without surfactant was found to be less as compared to its application with surfactants. Higher dose of this formulated herbicide i. e. 54 g/ha was more effective than its lower levels. Also alone application of carfentrazone 20 g/ha as well as unweeded (control) treatment produced significantly higher dry matter of P. minor and less grain yield as compared to all the herbicidal treatments.

Abstract:

A field experiment was carried out at Research Farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal during winter (rabi) seasons of 2007-08 and 2008-09 to study the efficacy of different weed management practices on economical, quality wheat (variety PBW 343) seed production. Uncontrolled weeds reduced the wheat seed yield upto 34%. Highest wheat seed yield was observed with two manual weedings followed by hoeing (dutch hoe) + isoguard plus, due to effective weed control.  Despite of additional cost for weed management, all the weed management treatments resulted in additional wheat seed production and additional benefit. Wheat seed produced by weed management in wheat with hoeing at 21 DAS + isoguard plus 1250 g/ha or metribuzin 175 g/ha at 28 DAS showed high vigour in seedling parameters though other treatments were also better than weedy check and seed of local farmers’ field.

Abstract:

There is lack of information on the effects of rice residue position and load on the growth and development of Phalaris minor Retz. and the efficacy of different herbicides in wheat under different rice residue management situations. The studies revealed that surface application of rice residues @ 6 and 7 t/ha significantly reduced the growth and development of P. minor and recorded higher weed control efficiency as compared to incorporation and no rice residue treatments. Application of rice residues @ 6 and 7 t/ha also significantly reduced the emergence of wheat seedlings as compared to rice residue incorporation and no rice residue treatments.  Wheat growth parameters, yield attributes, grain and biological yield were statistically at par in all the rice residue management techniques. Application of clodinafop 60 g/ha, sulfosulfuron 25 g/ha and mesosulfuron + iodosulfuron 14.4 g/ha significantly reduced the growth and development of P. minor and registered higher weed control efficiency as compared to unweeded control. Consequently, all the herbicidal treatments recorded significantly higher wheat growth parameters, yield attributes, grain and biological yield as compared to unweeded control treatment.

Abstract:

Field experiments were conducted at Karnal (Haryana) and Pusa (Bihar) during kharif 2006 to assess efficacy of azimsulfuron alone and in combination with ready mix of metsulfuron+chlorimuron (almix)  applied to the dry direct seeded rice (DSR) crop. Azimsulfuron at 25-30 g/ha applied 25 days after sowing controlled effectively broadleaf weeds and sedges especially Cyperus rotundus in DSR but failed to control grasses.Tank mixing of almix did not improve efficacy of azimsulfuron for the control of grasses, sedges or broadleaf weeds across the locations. Azimsulfuron alone or tank mixed with almix was not effective against grasses. On an average, uncontrolled weeds reduced the grain and straw yield of rice by 42 and 46%, respectively. Azimsulfuron applied alone or in tank mixed with almix and pre-emergence application of pendimethalin followed by almix had no toxicity in rice cultivar HBC-119 but phytotoxicity was observed in rice cultivar Rajshree at Pusa with higher doses of azimsulfuron.

Abstract:

Experiments to compare different seedbed techniques and non-chemical methods in wet seeded rice were conducted during 2005-06 and 2006-07.  The trials were laid out in a split plot design with three main plots, five sub-plots and three replications.  Adopting stale seedbed technique either for 7 or 14 days significantly reduced the population of grass weeds. It gave successful control of broadleaf weeds too. Among the weed management treatments, pre-emergence spraying of (Sofit) pretilachlor+safener and concurrent growing of sesbania gave significant reduction in the population and dry weight of weeds.  Pretilachlor spray exhibited the greatest influence on broadleaf weeds.  Stale seedbed preparation significantly improved grain and straw yields of wet seeded rice compared to normal seedbed.  An increase in stale seedbed period contributed to corresponding increase in yields as evident by higher grain and straw yields in plots with stale seedbed for 14 days.  Among the weed control treatments tried, pretilachlor+safener sprayed and hand weeded plots gave higher yields.

Abstract:

A field experiment was conducted during kharif 2009 at Zonal Agricultural Research Station, V. C. Farm, Mandya, Karnataka. The  experiment consisted of  12 treatments laid out in randomized complete block design with three replications consisting of four pre-emergence herbicides integrated with one intercultivation at 40 days after sowing, hand weeding twice at 20 and 40 days after sowing, intercultivation thrice at 20, 40 and 60 days after sowing compared with weed free and unweeded check. The predominant weed flora observed in the experimental field were Echinochloa colonum, Digitaria marginata, Ageratum conyzoides, Spilanthus acmella, Commelina benghalensis, Celosia argentia, Cyperus iria and Cyperus rotundus. The results revealed that pre-emergence application of bensulfuron methyl+pretilachlor (6.6 GR) @ 0.06+0.60 kg/ha+one intercultivation at 40 days after sowing recorded significantly higher grain and straw yield (4425 and 5020 kg/ha, respectively), lower weed population and their dry weight (17.0 g and 2.32 g 0.25/m2, respectively). Further the net returns and B : C ratio were also high with the pre-emergence application of bensulfuron methyl + pretilachlor (6.6 GR) @ 0.06 + 0.60 kg/ha+one intercultivation at 40 days after sowing.

Abstract:

A field experiment was conducted during the Rabi 2004-05 and 2005-06 to study the effect of planting pattern and weed conrol practices on weed dynamics and productivity of sweet corn. Planting pattern of 60 x 20 cm with 83,333 plants/ha proved to be very effective in suppressing weeds, recording the lowest density of grasses, sedges and broad-leaved weeds at 30 and 45 days after sowing (DAS). At harvest also, it resulted in the lowest total weed density, weed dry weight with the highest weed control efficiency (WCE) and was at par with 75 x 16 cm. These two planting patterns were found to be significantly superior to 60 x 25 cm and 75 x 20 cm with 66,666 plants/ha. Though the highest cob length and green cob weight of sweet corn were realized with 60 x 25 cm, the green cob (13.9 and 13.2 t/ha) and green fodder yield (17.6 and 16.6 t/ha) were found to be the highest with 60 x 20 cm and resulted in higher net returns (Rs. 24, 987 and 23,024/ha). Pre-emergence application of atrazine @ 1 kg/ha followed by (fb) hand weeding at 30 DAS provided significant weed control during the citical crop-weed competition period in sweet corn upto 45 DAS. It also recorded the lowest total weed density and dry weight with the highest weed control efficiency at harvest, which resulted in the highest green cob yield (14.2 and 13.4 t/ha) and green fodder yield (18.0 and 17.1 t/ha) of sweet corn with enhanced net returns (Rs. 25,251 and 23,221/ha) and B : C ratio, though at par with two hand weedings at 15 and 30 DAS and pre-emergence application of atrazine @ 1 kg/ha fb post-emergence application of paraquat @ 0.5 kg/ha at 30 DAS. Uncontrolled weed growth throughout the crop growth period reduced the green cob yield to an extent to 40-42% during both the years of experiment.

Abstract:

Cyperus rotundus is a troublesome perennial weed of kharif season. In maize, it is not controlled with the already recommended herbicide i. e. atrazine 50 WP. All the three formulations of 2,4-D i. e. sodium, di-methyl amine and ethyl ester were applied as post-emergence on C. rotundus infested crop of maize from 2007 to 2009 as blanket spray after the pre-emergence application (20-25 DAS) of atrazine 1.0 kg/ha. Out of the three formulations, post-emergence application of 2,4-D di-methyl amine at 0.44, 0.58 and 0.73 kg/ha was found more effective for controlling C. rotundus as compared to other formulations i. e. sodium and ethyl ester. All the three formulations showed no adverse effect on plant growth and produced grain yield of maize statistically similar to each other. On an average of three years, post-emergence application of 2,4-D di-methyl amine at 0.44, 0.58 and 0.73 kg/ha increased maize grain yield significantly over unweeded control and all these treatments produced 23.8, 31.1 and 26.7% higher yield than unweeded control treatment, respectively.

Abstract:

A field experiment was conducted at CCS Haryana Agricultural University Regional Research Station, Karnal during rabi 2006-07 and 2007-08 to evaluate the efficacy of tank-mix combinations of different herbicides against Phalaris minor in wheat. The experimental field was dominated mainly by grassy weed P. minor Retz. The major weeds among broad-leaved weeds (BLW) were Coronopus didymus L., Anagallis arvensis L., Melilotus indica All. Fl. Ped., Medicago denticulata L., Rumex dentatus L., Vicia sativa L. and Lathyrus aphaca L. Intra-group combinations of herbicides viz., ACCase inhibitor (clodinafop/fenoxaprop/pinoxaden) with ACCase inhibitor and ALS inhibitor (sulfosulfuron/ mesosulfuron+iodosulfuron) with ALS inhibitor were compatible and resulted in very effective control of P. minor and consequently yields of wheat (5552-5861 kg/ha in 2006-07 and 5510-5897 kg/ha in 2007-08) were comparable to weed free checks (5909 kg/ha in 2006-07 and 5850 kg/ha in 2007-08). While inter-group combinations (clodinafop/fenoxaprop/pinoxaden with sulfosulfuron/mesosulfuron+iodosulfuron) were not found compatible and resulted in lower control of P. minor with lower yields (5054-5239 kg/ha in 2006-07 and 4285-4976 kg/ha in 2007-08). Alone application and all combinations having sulfosulfuron or mesosulfuron + iodosulfuron provided good control of BLW even under inter-group combinations. There was no phyto-toxicity of any of the herbicidal treatments on wheat, except some recoverable symptoms under treatments having mesosulfuron+iodosulfuron during 2007-08

Abstract:

A field experiment was carried out during the Rabi seasons of the years 2007-08 and 2008-09 at Junagadh (Gujarat) to study the effect of some herbicides for weed management in garlic and their persistence. The results indicated that all the treatments reduced the density and dry weight of weeds and increased yield and yield attributes significantly over unweeded check. A pre-emergence application of oxyfluorfen 240 g/ha showed its effect on indicator plants like sorghum and cucumber. Effect of oxadiargyl 90 g/ha was observed on cucumber at 30 DAS which disappeared at 60 DAS. Post-emergence application of oxadiargyl 90 g/ha, quizalofop-ethyl 40 g/ha and fenoxaprop-p-ethyl 75 g/ha made at 60 DAS did no show persistence effect on sorghum and cucumber at 90 DAS. Similarly, post-harvest study on succeeding crops of groundnut, greengram and pearl millet indicated that there was no residual phytotoxic effect of either pre- or post-emergence herbicides tested in the experiment.

Abstract:

Laboratory and screen house experiments were conducted to evaluate the effect of temperature, salinity, osmotic potential, light/dark periods, seeding depth and flooding on germination of Convolvulus arvensis and Lathyrus aphaca. Maximum germination of C. arvensis (41%) and L. aphaca (91%) was recorded at 20°C which decreased with any increase or decrease from optimum temperature. C. arvensis and L. aphaca had maximum germination with distilled water compared with salt solution. C. arvensis and L. aphaca germination was 20 and 55%, respectively, at 200 mM NaCl conc. Osmotic potential of -0.8 MPa reduced the germination of C. arvensis to zero, whereas 3% L. aphaca germinated at this stress. Light was not pre-requisite for the germination of these weed species. Optimum depth for the germination of C. arvensis and L. aphaca was 1.0 cm where corresponding germination was 40 and 79%, respectively. Reduction in germination and growth was recorded with increase and decrease from the optimum depth. L. aphaca was able to germinate and emerge from higher depths of 8.0 cm. Tolerance towards flooding was significant for both species as C. arvensis tolerated 20 days of flooding, whereas L. aphaca germinated (17%) after 40 days of flooding and 2% after 80 days of flooding. These factors can be exploited for their management.

Abstract:

A field study was undertaken, at S.V. Agricultural College, Tirupati during the Rabi seasons of 2002 and 2003 to identify effective and economical weed management options for sunflower by studying the effect of planting pattern and weed management practices on weed flora and seed yield of Rabi sunflower. Planting pattern of 45 x 30 cm recorded significantly lower weed density and biomass thus resulting in higher seed yield over 60 x 22.5 cm. Among the weed management practices, the lowest density and biomass of weeds at harvest were recorded with hand weeding (HW) twice closely followed by fluchloralin at 0.5 kg/ha+ pendimethalin at 0.5 kg/ha supplemented with one HW at 40 DAS. However, sunflower seed yield was the highest with HW twice followed by application of pendimethalin at 1.0 kg/ha.  The use of planting pattern of 45 x 30 cm and managing associated weeds with HW twice at 20 and 40 DAS or pre-emergence application of pendimethalin at 1.0 kg/ha resulted in higher net returns and seed yield of irrigated Rabi sunflower.

Abstract:

Herbicides being biologically active compounds, an unintended consequence of the application of herbicides is that it may lead to significant changes in the populations of microorganisms and their activities thereby influencing the microbial ecological balance in the soil and affecting the productivity of soils. The increasing reliance of rice cultivation on herbicides has led to concern about their ecotoxicological behaviour in the rice field environment. Hence, in this study, the herbicides viz., 2,4-DEE, butachlor, pretilachlor and pyrazosulfuron ethyl were evaluated at different concentrations of 1 FR (Field rate), 2 FR (two times field rate), 5 FR, 10 FR and 100 FR for their effect on total heterotrophic bacteria, fungi and  actinomycetes in laboratory microcosms. The results of this experiment revealed that the application of herbicides reduced the population of all the bacteria counted during the study with butachlor showing highest reduction in the populations. This effect was stronger with increasing concentration of the herbicides employed. However, the populations at 1 FR (and also 2 FR for pyrazosulfuron ethyl) concentrations recovered within 30 days to reach populations not significantly different from the control treatments.
