Indian Journal of Weed Science is a quarterly journal publishing original research article, research notes, opinion articles and review articles (invited or with prior approval of the title reflecting substantial contributions of the author) covering all areas of weed science research. All contributions must be of a sufficient quality to extend our knowledge in weed science.

The papers submitted should not have been published or communicated elsewhere. Authors will be solely responsible for the factual accuracy of their contribution. Manuscript should not carry any material already published in the same or different forms.

  • 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.

Manuscript submission

Manuscripts must conform to the journal style (see the latest issue). Correct language is the responsibility of the author. After having received a contribution, there will be a review process, before the Chief Editor makes the definitive decision upon the acceptance for publication.

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:

A survey was conducted in major rice tracts of Kerala i.e. Kole, Kuttanad and Palakkad during 2018 and 2019 to assess the distribution and occurrence of Sacciolepis interrupta. In Palakkad and Kole tract the highest density, frequency, abundance, relative density, relative frequency, and summed dominance ratio of Sacciolepis was recorded whereas, in Kuttanad tract it was Echinochloa crusgalli followed by Sacciolepis. Weed vegetation analysis indices were lowest in Palakkad compared to Kole and Kuttanad tract showing a high degree of domination of one species in Palakkad and larger diversity of weed species in other two tracts. The cluster analysis classified Sacciolepis types into 6 groups at 66.67% similarity level, and using principal component analysis these morphotypes were clustered into 3 groups A, B and C based on morphological characters. Association between Sacciolepis types and soil nutrient parameters indicated that Group A was abundant in less fertile saturated soils whereas group B and C were dominant in nutrient rich submerged soils of Kole and Kuttanad. The study concludes that Sacciolepis interrupta is a serious weed problem in direct seeded rice of Palakkad tract and is fast attaining the status of a dominant weed in other rice tracts also, thereby becoming a major menace in rice fields of Kerala.

Abstract:

A field experiment was conducted to evaluate the efficacy of penoxsulam 0.97%w/w (1.0%w/v) + butachlor 38.8% w/w (40% w/v) 41% SE applied as pre-emergence( 0-7DAT) spray in standing water against complex weed flora in transplanted rice at CCS HAU Regional Research Station, Karnal during rainy (Kharif) seasons of 2015 and 2016. The crop was infested mainly with Echinochloa crus-galli (~15%), Ammannia baccifera (~70%), and Cyperus difformis, Cyperus rotundus and other sedges (~15 %). Penoxsulam + butachlor 41% SE at 820 g/ha being as good as weed free check provided almost complete control (98.1-98.5% WCE) of complex weed flora during both the years, and it was better than penoxsulam 22.5 g/ha (87-88%), butachlor 1500 g/ha (90%) and pretilachlor 1000 g/ha (91%). Penoxsulam + butachlor 820 g/ha resulted into the highest number of effective tillers and grain yield (5.43 t/ha in 2015 and 6.06 t/ha in 2016). It was superior to its lower doses (615 and 718 g/ha) and penoxsulam 22.5 g/ha during both the years, and butachlor 1500 g/ha during 2016. There was no crop phyto-toxicity of penoxsulam + butachlor 41% SE at 820 g/ha (X) and 1640 g/ha (2X). Weeds allowed to grow throughout the crop season reduced the grain yield to the extent of 27.3 and 32.9% during 2015 and 2016, respectively.

Abstract:

The field experiment was conducted at Agronomy Department Farm, College of Agriculture, Dapoli, during Kharif (rainy) seasons 2016 and 2017 to study the effect of established by different methods of rice establishment on weeds. The field experiment was laid out in a strip plot design comprising of twenty five treatment combinations replicated thrice. The horizontal strips comprised five rice establishment methods, viz. sowing of dry seeds by drum seeder at onset of monsoon, sowing of sprouted seeds (Rahu) by drum seeder in puddled field, broadcasting of sprouted seeds (Rahu) in puddled field, system of rice intensification (SRI) method and conventional transplanting. The vertical strips consisted five weed management practices, viz. need based two hand weedings at 20/30 and 40/60 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + 1 hand weeding at 20/30 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + 1 hand weeding at 40/60 DAS/DAT, pre-emergence application of oxadiargyl 80 WP 100 g/ha + post-emergence application of Almix 20 WP 4 g/ha and unweeded control. SRI method with two hand weedings carried out at 20 and 40 DAT recorded highest grain and straw yield of rice and lowest weed density and dry weight of weeds as compared to remaining treatment combinations during both the seasons.

Abstract:

The present investigation was conducted to evolve a suitable weed management practice for invasive alien weeds in transplanted rice at Annamalai University Experimental Farm, Annamalainagar, during samba seasons of consecutive years (2015 and 2016). The experiments were laid out in a split plot design with the conventional rice and submergence tolerant rice varieties compared in main plot. Weed management practices, viz. unweeded control, twice hand weeding (at 30 and 45 DAT), butachlor 1.5 kg/ha, bensulfuron-methyl 0.06 + pretilachlor 0.6 kg/ha and oxadiargyl 0.07 kg/ha were compared in sub treatments. The results indicated that submergence tolerance as a biological or genetic trait in crops helped suppressing invasive alien weeds like Leptochloa chinensis and Marsilea quadrifolia, offering biotic resistance to invasion by alien weeds and when integrated with weed control measures. Hence, weed control in submergence tolerant rice with the application of bensulfuron-methyl 0.06 + pretilachlor 0.6 kg/ha could be suggested as an efficient weed control programme for monsoon transplanted rice crop.

Abstract:

Effects of ten diversified rice based cropping sequences on weed dynamics were evaluated at Banaras Hindu University, Varanasi (Uttar Pradesh) in different season during 2016-17 and 2017-18. The results revealed that density of Cyperus spp., Cynodon dactylon and Digitaria sanguinalis was significantly lowest in rice-potato-greengram sequence but it remained at par with rice-berseem-cowpea fodder, rice-cabbage-cowpea fodder and rice-potato-cowpea fodder during second year in rainy season. Dry weight of Digitaria sanguinalis was significantly lowest under rice-potato-greengram sequence. During winter season, significantly lower density and dry weight of Medicago denticulata, Chenopodium album as well as total weeds were recorded in mustard (rice-mustard-cowpea fodder), though it was found similar with mustard (rice-mustard-sudan grass fodder), potato (rice-potato-greengram and rice-potato-cowpea fodder) and wheat (rice-wheat, rice-wheat-greengram and rice-wheat-cowpea fodder). While, density of Cynodon dactylon was markedly lower in wheat (rice-wheat) it was on a par with mustard (rice-mustard-sudan grass fodder), potato (rice-potato-green gram, rice-potato-cowpea fodder) and wheat (rice-wheat-greengram, rice-wheat-cowpea fodder). During summer season, cowpea grown in rice-cabbage-cowpea fodder recorded significantly lower density as well as dry weight of Cyperus rotundus, Cynodon dactylon as well as total weeds. Grain yield of rice was significantly higher in rice-berseem-cowpea fodder. During winter season, berseem in rice-berseem-cowpea fodder sequence out yielded all the other crops. However, in summer, sudan grass in rice-mustard-sudan grass fodder produced the highest green fodder yield.

Abstract:

A field experiment was conducted during 2015-16 and 2016-17 at Rajasthan College of Agriculture, Udaipur, India to evaluate the bio-efficacy of readi-mix herbicides in late sown wheat. The experiment consisting of fifteen treatments was laid out in randomized block design with four replications. The results revealed that Readi-mix application of sulfosulfuron + metsulfuron (32 g/ha)) and mesosulfuron + iodosulfuron (14.4 g/ha) gave higher weed control index (95.36, 94.72%), lower weed index (2.00, 2.75%) and weed persistence index (0.349, 0.351) whereas, higher index value of crop resistance index (CRI), weed management index (WMI) and herbicide efficiency index (HEI) (28.61, 0.38 and 5.50). Both of these treatments recorded 34.3 and 33.3 per cent grain yield enhancement along with 49.0% and 47.7% higher net returns over the unweeded control with the highest benefit-cost ratio (2.34 and 2.32). Results from contract analysis indicated significant (p < 0.0001) interaction of year x treatments and response of Readi-mix v/s single/sequential herbicide application on grain yield, weed density and dry matter. The joint effect of parameters on grain yield was significant with high magnitude (RGY.Weed density total, Weed dry weight total, Total N, P and K uptake = 0.98; p < 0.0001). Additionally, the regression model for grain yield on total weed density (R2 = 0.84), weed dry weight (R2=0.79), total N uptake (R2=0.98), P uptake (R2=0.93) and K uptake (R2 = 0.97) demonstrated significant dependence. Moreover, no symptoms of phytotoxicity were seen in any of the treatment in the crop at 21 days after herbicide application.

Abstract:

A field experiment was conducted in Rabi 2016-17 and 2017-18 to assess the effect of 2,4-D sodium salt at 5, 10, 20, 40 and 50 g/ha along with the recommended dose of 500 g/ha on wheat and associated dicotyledonous weeds (Medicago denticulata and Rumex dentatus). Foliar applied 2,4-D in the range of 5-20 g/ha increased the chlorophyll content index (CCI) and chlorophyll fluorescence (Fv/Fm) values in wheat as compared to control, demonstrating biphasic dose response (hormetic effect) of this auxinic herbicide. But the stimulatory effect of 2,4-D at low doses was observed only upto flag leaf stage of crop. Grain and straw yield of wheat was not boosted significantly by the low doses of 2,4-D, indicating that growth stimulation by sub-toxic doses of 2,4-D was not sustained over time. The foliar application of 2,4-D at ultra-low doses of 5-50 g/ha did not exert hormetic effect in R. dentatus and M. denticulata as application of different doses of 2,4-D led to a reduction in seed production potential of these weeds.

Abstract:

A field experiment was conducted at Advanced centre for rainfed agriculture, Rakh Dhiansar of Sher-e- Kashmir University of Agricultural Sciences and Technology of Jammu during the crop growing seasons of 2016 and 2017 to identify the best herbicide option for weed management in maize (Zea mayz L.). Fifteen treatments were tested in randomised block design replicated thrice.  The post-emergence treatment (PoE) of tembotrione 100 g/ha + atrazine tank mix formulation 750 g/ha at 15-20 days after sowing (DAS) has recorded highest weed control efficiency (93.22 and 93.71% during 2016 and 2017, respectively) followed by tembotrione 100 g/ha + atrazine 500 g/ha at 15-20 days after sowing (DAS) and sequential application of atrazine 1000 g/ha 0-3 DAS fb tembotrione 100 g/ha 15-20 DAS. Higher maize grain yield was recorded (3.64 t/ha and 3.74     t/ha during 2016 and 2017, respectively) with weed free which was statically at par with tembotrione 100 g/ha + atrazine 500 g/ha at 15-20 DAS, tembotrione 100 g/ha + atrazine 750 g/ha at 15-20 DAS, tembotrione 100 g/ha + halosulfuron 67.5 g/ha at 15-20 DAS, tembotrione 100 g/ha+ halosulfuron 52.5 g/ha at 15-20 DAS, atrazine 1000 g/ha 0-3 DAS  fb metribuzin 250 g/ha 15-20 DAS, atrazine 1000 g/ha 0-3 DAS  fb tembotrione 100 g/ha 15-20. B: C ratio (3.11 and 3.12 in 2016 and 2017 respectively) was high with PoE application of tembotrione 100 g/ha + atrazine 500 g/ha.

Abstract:

A field experiment was conducted at Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal, India in Kharif season of 2016 and 2017 to evaluate the phytotoxicity of glufosinate ammonium 13.5% SL (15% w/v) on cotton and soil micro-flora and their consequent effects on crop growth, yield and economics. Findings depicted that there were no phytotoxic symptoms on cotton and there was better recovery of soil micro-flora population with the application of glufosinate ammonium 13.5% SL (15% w/v) 450 g/ha, resulting in maximum growth, yield and economic profitability of cotton. However, prominent toxic effects of glufosinate ammonium 13.5% SL (15% w/v) on the crop and soil micro-flora were recorded at higher doses of 900 g/ha and 1800       g/ha, which significantly reduced cotton growth, yield and economic viability.

Abstract:

A field trial was conducted during two consecutive Rabi season of 2016-17 and 2017-18 on loamy sand soil at AICRP-Weed Management, B.A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) to study the effect of integrated weed management in fennel production system and its residual effect on succeeding summer greengram. Significantly, lowest and highest weeds density at harvest was recorded with farm yard manure (FYM) 20 t/ha and vermicompost 8.0 t/ha, respectively. However, highest fennel seed yield (2.09     t/ha) was recorded with vermicompost 8.0 t/ha application. Significantly higher plant height, number of umbels/plant and seed yield was recorded with paddy straw mulch 10 t/ha fb hand weeding (HW) at 30 and 60 days after transplanting (DATP) and it was at par with paddy straw mulch 5 t/ha fb HW at 30 and 60 DATP and twice inter cultivation (IC) + HW at 30 and 60 DATP fb earthing-up at 75 DATP. Higher fennel equivalent yield (2.43 t/ha) and gross return ( 243000/ha) was recorded with application of vermicompost 8.0 t/ha, while highest net return ( 138220/ha) and benefit cost ratio (2.56) was recorded with application of FYM. Paddy straw mulch 10 t/ha fb HW at 30 and 60 DATP recorded higher fennel equivalent yield (3.24 t/ha), gross returns ( 219816/ha), net returns ( 241976/ha) and benefit cost ratio (3.11). Application of FYM and vermicompost was found equally effective while mulching treatments recorded higher seed yield of succeeding greengram.

Abstract:

Golden crownbeard (Verbesina encelioides), which is abundant along roadsides in Northern India, has started to invade field borders in the South West of Punjab. This study was conducted to find the effect of environmental factors and accelerated ageing on germination of this weed. It germinated over a wide range of temperatures (15/5-35/25°C) with optimum germination at 25/15°C. Light was not a pre-requisite for germination. Germination was completely inhibited at -0.6 MPa. The seeds germinated at 160 mM sodium chloride (13.3%), but no germination was observed at 180 mM NaCl. Germination of seeds was very low at pH less than 5 or more than 8. Germination was 95% when seeds were placed on the soil surface. No emergence was observed when seeds were buried to 6 cm or greater depth. Accelerated ageing of seeds for 20 or more days completely inhibited germination. Results indicate that this weed can emerge in multiple germination flushes. It also has the ability to invade drought affected areas, and can grow in soils that are moderately saline, slightly acidic, or alkaline. However, this weed is not expected to buildup persistent soil seed banks due to rapid loss of viability (time to 50% persistence = 4.11 days) under accelerated ageing.

Abstract:

A study on weed flora was conducted to evaluate the weed species distribution across different brown mustard (Brassica rapa var. brown sarson) growing areas of Kashmir valley during Rabi (2016-17 and 2017-18). The occurrence of weed species was assessed on the basis of different phyto-sociological attributes, viz. weed species density, relative density, relative frequency and importance value index. These were computed from the data collected during the month of March. In all twenty weed species were identified of which sixteen were broad-leaved. The crop was highly infested with the weed species of Poaceae family with the dominance of Poa annua (IVI of 84.9, 50.6 and 44.1 in Pulwama, Anantnag and Kulgam, respectively). Among the broad-leaved weeds, Veronica persica was the most dominant species found in Budgam with the abundance value of 17.25 and IVI of 34.5. Budgam had the highest weed species distribution with Simpson’s diversity index (D) of 0.120123.

Abstract:

Weed management and planting methods in potato cultivation affect the tuber yield and quality significantly, and hence, requires proper management. Therefore, to explore the possibilities of developing a pre-emergence (PE) herbicide application system for potato planter specially for cut seed pieces (tubers) a study was conducted at ICAR-Directorate of Weed Research (DWR) during Rabi season of 2017-18 and 2018-19. The study includes different sprout-eye orientation of the potato tubers along with different weed management practices. The application of metribuzin at 0.75 kg/ha as PE effectively controlled the weeds and obtained a weed density of 2.43 and 2.04 weeds/m2 and weed dry biomass of 1.35 and 1.64 g/m2 respectively at 25 and 55 DAP. By application of the metribuzin as PE and paraquat as early-post emergence (PoE), the tuber yield was increased from 9-16.5%. The sprout-eye orientation has significant effect on tuber yield. The tuber yield was reduced by 28.3% and 16.7% respectively, in 2700 sprout-eye orientation and random dropping over sprout-eye orientation of 90±300. The highest tuber yield of 28.4 t/ha was obtained in planting of whole tuber having the size of 40 to 50 g per tuber. The application of metribuzin as PE effectively controlled the weeds, thus a PE applicator system can be developed along with the potato planter.

Abstract:

Weeds result in yield losses up to 40% in maize in India. Brown manuring can suppress weeds better and provide ecosystem services. It has been hardly studied in crops other than rice. It offers potential for adoption in maize, but needs to be optimized because maize differs from rice in growth habit and architecture and has no tillering capacity. Therefore, this study was undertaken to optimize brown manuring option(s) that involved two brown manure species, their mixture and seed rates, and the times of application of 2,4-D. Results revealed that all brown manuring treatments suppressed noxious weed Cyperus rotundus better than the recommended tank-mixture of atrazine + pendimethalin. Among them, a brown manuring option that involved 1:1 mixture of Sesbania bispinosa (12.5 kg seed/ha) + Crotalaria juncea (12.5 kg seed/ha) + 2,4-D 0.5 kg/ha applied at 35 DAS resulted in highest reduction in weed density (~91%). Another brown manuring option, i.e., Sesbania  + Crotalaria (12.5+12.5 kg/ha) mixture and 2,4-D 0.5 kg/ha applied at 25 DAS gave similar weed suppression, and was superior to it on maize grain yield (~13.4%), gross return (~15.7%) and gross benefit:cost (~15.6%). This brown manuring would be a profitable weed management practice in maize. It may lead to sequester C and N in soil and provide ecosystem services as well.

Abstract:

Alternanthera ficoidea (Sanguinarea) (Amaranthaceae) is an exotic weed that has widely spread in most of the terrestrial habitats including saline soils under different climatic conditions. Seed germination is an important stage in seedling establishment and maintaining health and vigour of every plant. Seed germination studies were carried out under temperature and salinity stress. Weed seeds showed adaptation to temperature as well as salinity stress in laboratory as well as field conditions. Such type of adaptation may be one of the reasons for rapid spread and establishment of this weed.

Abstract:

Herbicides are now used throughout the globe and a majority of applied chemicals enter into the soil to form short or long-term residues, resulting in toxicity to sensitive crops and adverse effects on human and other life forms. Therefore, present work was undertaken to isolate and identify pyrazosulfuron-ethyl degrading fungi from soil of rice field. Alternaria alternata was isolated and identified from rhizosphere soil of rice field, as a potent pyrazosulfuron-ethyl degrading fungus and its degradation potential was evaluated under controlled conditions. In the soil pyrazosulfuron-ethyl was efficiently degraded by A. alternata. Degradation of pyrazosulfuron-ethyl by A. alternata was achieved by the cleavage of sulfonylurea bridge and hydrolysis. A. alternata used in the study can effectively be used for the enhanced degradation of pyrazosulfuron-ethyl in agricultural soil or mixed with other microbial consortia for rapid degradation with half life of 7.9 days.
