  • 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’.

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. Referee's comments along with editors comments will be communicated to authors as scanned copy/soft copy through email. After revision, author should send back the copy of revised manuscripts to the Chief Editor, ISWS by e-mail only.

Editorial Board reserves the right to suitably modify, accept or reject the MS in view on the reviewer's advice.

We encourage submission of paper only by electronically via E-mail as one complete word document file. When preparing your file, please use only Times New Roman font for text (title 16, all heads 14 and text of 12 point, double spacing with 1.5" margin all the sides) and Symbol font for Greek letters to avoid inadvertent character substitutions.

All manuscripts should be submitted Online (http://www.isws.org.in/login_IJWS.aspx). For authors unable to submit their manuscript online

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)

Abstract:

Isoproturon at 1.0 kg. metoxuron at 1.6 kg and methabenzthiazuron 1.4 kg ha-' applied at 3-leaf stage provided more than 80% control of both susceptible (5) biotypcs (RI and H2) of P. milloI': however. these herbicides were ineffective against resistant (R) biotypes (H3, KRI and UPI) even at higher doses. Mon-48549 at 25 and 50 g, and Foe5043 at 300 and 600 g ha-' also did not control this weed satisfactorily. Performance of diclofop and metribuzin was also erratic against Rand S biotypes. Clodinafop at 60 g, fenoxaprop at 120 g, sulfosulfuron at 25 g and tralkoxydim at 350 g ha-' applied at 3-leaf stage resulted in 82-95% reduction in the dry weight of R as well as 5 biotypes of P. lIlilUJI: Metribuzin at 200 and 400 g ha", and Mon-48549 at 25 and 50 g ha-' caused 15 to 30% phytotoxicity to wheat. Metribuzin either alone or in mixture caused phytotoxicity to wheat crop without adding to weed control efficiency (WCE).

Abstract:

Pot experiments were conducted to find out GR,,, values of isoproturon. clodinafop. sulrosulfuron and fenoxaprop-p-ethyl for controlling Phalaris minor. Clodinafop. sulfosulfuron and fenoxaprop-p-ethyl were recommended at 60. 25 and 100 g ha". On an average of two years, GR,o values for isoproturon. clodinafop, sulfosulfuron and fenoxapropp- ethyl were found to be 1210, 2.47. 2.08 and 7.58 g ha-I, respectively. Among the alternate herbicides, lowest GR,,, value was observed in clodinafop which was followed by sulfosulfuron and fenoxaprop-p-ethyl and these values were many times lower than their recommended doses; however. GR,o values for isoproturon were found to be much higher

 

than even its recommended dose.

Abstract:

Weed control efficacy of clodinafop applied at varying doses with surfactant and without surfactant was evaluated in wheat. With the increase in the doses of clodinafop from 40 to 50 or 60 g ha·'. there was a gradual decline in the population and dry matter accumulation of grassy weeds. Addition of surfactant (0.25 or 0.5 or 1.0%) enhanced the grass weed control efficacy of c1odinafop. However, no significant difference was observed in c1odinafop efficacy with different surfactant concentrations. Clodinafop did not provide any control of broad leaf weeds. Maximum wheat yields of 4891 and 5163 kg ha" were observed in season long free situations followed closely by diclofop-methyl 700 g. c1odinafop 60 and 50 g with surfactant applied after first irrigation.

Abstract:

Oiclofop, metsulfuron, 2, 4-0 Na, diflufenican, clodinafop, fenoxaprop, tralkoxydim and isoproturon applied in wheat did not exhibit any adverse effect on various kharif crops of mungbean, maize, cowpea, pigeon pea, pearl millet and cotton. Chlorsulfuron at 30 g ha" sprayed in wheat had no residual effect on mu,!gbean but at 60 and 120 g ha" had residual toxicity to mungbean. Compared to mungbean and cotton, maize was more sensitive to chlorsulfuron. Sulfosulfuron at 25 g ha" and pendimethalin at 1500 g ha" applied in wheat also caused residual toxicity to maize but not to mungbean and cotton. Metribuzin at 300 and 400 g ha" caused significant residual toxicity to mungbean and maize, and at 400 g ha" to cotton. Chlorsulfuron, sulfosulfuron, metribuzin and pendimethalin significantly reduced the density and dry weight of Trianthema portulacastrum at 210 days after treatment.

Abstract:

Chlorsulfuron, clodinafop, fenoxaprop, sulfosulfuron, tralkoxydim and dithiopyr alone and in combination were evaluated against complex flora of weeds in wheat. All the herbicidal treatments significantly reduced the dry weight of complex weeds. Chlorsulfuron was effective against broadleaf weeds and ineffective against grassy weeds. Fenoxaprop, clodinafop and tralkoxydim controlled grassy weeds but not the broadleaf weeds. Sulfosulfuron was very effective against grassy weeds and also to some extent against non-grassy weeds. Dithiopyr alone or in tank mixture was ineffective. Tank mixture of fenoxaprop+ chlorsulfuron at 100+20 g, clodinafop+chlorsulfuron at 50+20 g, tralkoxydim+ chlorsulfuron at 250+20 g and sulfosulfuron+chlorsulfuron at 15+10 g ha'\ provided 73-84% control of complex weed flora and being at par with each other produced grain yield of wheat similar to weed-free. Isoproturon+2, 4-D sodium salt at 750+500 g ha'\ resulted in 72-75% control of both types of weeds and produced grain yield equivalent to weed-free in one season.

Abstract:

Performance of irrigation time and weed management practices against weeds in wheat was evaluated. Chenopodium album L. and Chenopodium murale L. were predominating weed species and comprised about 76% of total weed population in weedy check. Pre-sowing irrigation reduced the dry weight of C. album and C. murale by 21 and 25%, respectively, and subsequently grain yield was 12% higher over post-sowing irrigation. Pre-emergence application of pendim~thalin at 0.75 kg ha" supplemented by one hand weeding or 2, 4-D, 0.50 kg ha" at 30 DAS gave significantly higher grain yield due to better weed control. However, the higher additional net return (Rs. 8063) was also obtained with pendimethalin at 0.75 kg ha"+one hand weeding.

Abstract:

Fenoxaprop. tralkoxydim and clodinafop. being very effective (87-91%) against Avella ludovicialla and Phalaris millor, were not effective against broadleaf weeds in wheat. Tank mixture of fenoxaprop+isoproturon at 1000 and 1250 g ha- I • and tralkoxydim+isoproturon at 250+375 and 250+500 g ha-J being statistically at par with each other and better than their alone applications, reduced the dry weight of complex weeds to the extent of 72-78%. Tank mixture of metribuzin with reduced dose of c1odinafop, fenoxaprop, sulfosulfuron, chlorsulfuron or tralkoxydim increased their efficacy against grassy weeds without any additional grain into grain yield of wheat. Isoproturon and metoxuron being at par with each other proved superior to alone applications of metribuzin and its tank mixed applications with isoproturon or metoxuron.

Abstract:

A field experiment was conducted for two summer reasons to identify critical period in irrigated summer sown blackgram (Vigna mungo L.) at Kanpur. Unchecked weed competition throughout the crop growth period caused a reduction of 40.10% in seed yield. Initial weed condition for the first 10 days after sowing did not cause significant loss in yield. Weed-free conditions maintained 40 days after sowing could not bring significant increase in seed yield. The critical period of crop-weed competition thus lies between 1040 days after sowing in irrigated summer sown blackgram.

Abstract:

Field experiments were conducted to study the efficacy of different weed management practices in sugarcane during 1997-99. Cyperus rotundus, Cynodon dactylon and Sorghum halepense were the dominating weeds associated with the crop and constituted 42, 21 and 17.5% of total weed population, respectively. One hoeing at 30 days after planting followed by application of atrazine at 2.0 kg ha'! (just after hoeing) provided 70.5% weed control efficiency. This also resulted in highest cane yield being 49.5% higher than weedy and 2.4% than three hoeings done at 30, 60 and 90 days after planting. The weed infestation did not affect juice sucrose content. Commercial cane sugar yield was highest (10.0 t ha'!) with three hoeings during 1997-98 and with one hoeing fb atrazine (11.0 t ha'!) during 1998-99, though the differences were non-significant.

Abstract:

Weed density and weed dry matter reduced significantly due to different weed control measures. Cane yield increased significantly with all the measures over weedy check and was highest under weed-free conditions though it was at par with manual hoeing 20, 40, 60 DAP and at harvest of intercrops. Cowpea was most effective in smothering weeds followed by greengram and blackgram. Cowpea, blackgram and greengram reduced cane yield by 5.2, 10.4 and 8.4%, respectively. Sugarcane+cowpea gave highest mean cane equivalent yield of 108.4 t ha·1 with net return of Rs. 68684 and B : C ratio of 2.24 as against 77 t ha·l, Rs. 43264 and 1.44 with sole sugarcane. CEY and net return also followed the same trend. Atrazine greatly hampered the emergence of the intercrops.

Allelopathic effect of basil (Tulsi) (Ocymum sanctum) on the germination of some weed species was evaluated. The germination of radish, redroot pigweed, hairy beggarticks and guineagrass was completely inhibited with addition of 7.5 g basil leaf powder to 100 g of sand as compared to plants grown in sand alone or in a mixture of sand and sphagnum. The germination of seeds was significantly inihibited in redroot pigweed (13%) and hairy beggarticks (12%) when grown in 10% (w/v) basil leaf extract as compared to distilled water. Significantly lower germination of 58, 47 and 45% with basil stem+root extract (at 2.5% w/v) was recorded, respectively, in radish, redroot pigweed and hairy beggarticks. The length of radicle+root in case of redroot pigweed and hairy beggarticks was significantly lower in basil stem+root extract (2.5% w/v) than in distilled water and was significantly reduced further when the extract concentration was increased to 5% (w/v).

Abstract:

A field experiment was conducted at K. N. K. College of Horticulture, J. N. K. V. v., Mandsaur (M. P.) under AICRP on Medicinal and Aromatic Plants during winter (rabi) seasons of 1995-96 and 1996-97 to find out the suitable weed management practices in opium poppy. Field studies revealed that pre-emergence (PE) application of isoproturon coupled with hand weeding (HW) at 30 days after sowing (DAS) proved more effective in reducing weed population and weed biomass and in increasing yield and attributes of opium poppy than isoproturon applied as pre-emergence alone. Isoproturon at 375 g ha" PE+HW at 30 DAS and isoproturon at 500 g ha· 1 PE+HW at 30 DAS were as effective as weed-free check in reducing density and biomass of weeds and in increasing yield attributing characters viz., capsules planrl, capsule diameter and capsule length and latex, seed and husk yields and net profit. Maximum weed mortality (WM, 92.1%) with latex yield (74.6 kg ha"), seed yield (711.3 kg hal), husk yield (744.3 kg ha") and net profit (Rs. 42990 ha") were recorded under weed-free check and it was closely followed by isoproturon at 375 g ha" PE+HW at 30 DAS and isoproturon at 500 g ha-' PE+HW at 30 DAS, where 83.6 and 90.1% WM, 70.1 and 62.8 kg ha-' latex yield, 664.3 and 605.3 kg ha-' seed yield, 677.8 and 593.9 kg ha-' husk yield and Rs. 42812 and 36154 ha- ' net profit were recorded, respectively. Morphine content of opium remained unaffected due to use of isoproturon in opium poppy. Uncontrolled weed growth caused 57.4% mean loss in latex (50.8%), seed (61.5%) and husk (59.8%) yields. Higher dose of isoproturon at 500 g ha-' PE caused 22.5% phytotoxicity on opium crop.

Abstract:

Corynespora cassicola, Curvularia sp., Curvularia lunata, Fusarium oxysporum, F. monilifonne, Monilia sp. and Trichoderma harzianum were isolated from Parthenium infested soil of Coimbatore district of Tamil Nadu. Spore suspension as well as culture filtrates of F. oxysporum and F. monilifonne were highly pathogenic to the weed and its seed germination and their pre-emergence and post-emergence applications at 5% level resulted in complete inhibition of seed germination and 100% wilt incidence, respectively. T. harzianum was highly pathogenic to the Parthenium seeds only but not to the established weed.
