  • 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.

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:

Comparative efficacy of penoxsulam against weed control in transplanted rice was studied at Agricultural Research Station, Ummedganj, Kota (Rajasthan). The experiment was laid out in randomized block design with 7 treatments and 4 replications. Results revealed that the major weed flora associated with the transplanted rice were grasses likeEchinochloa colonum and Echinochloa crusgalli; sedges like Cyperus rotundus, Cyperus difformis and Cyperus iria; and broad-leaved weeds like  Eclipta alba and Ammenia baccifera. Penoxsulam at 0.0250 kg/ha applied at 0-5 days after transplanting was most effective to check all types of weed growth. This treatment also gave the maximum grain yield and straw yield,  resulting in the lowest weed index, dry weight of weeds, weed persistence index and highest herbicidal efficiency index

Abstract:

A field study was conducted during 2009 at Raipur in an inceptisol with rainy season rice to evaluate the effect of herbicides application on biochemical characteristics of rhizosphere soil under different tillage systems. Four different types of tillage system were evaluated viz. (i) conventional-conventional (ii) conventional-zero (iii) zero-conventional and (iv) zero-zero. Among weed control measures, comparative effects of hand weeding and recommended herbicides application (butachlor as pre-emergence and fenoxaprop-p-ethyl + ethoxysulfuron as post-emergence herbicide 1.5 kg, 56.25 g and 15 g/ha, respectively) were tested compared with a weedy check (control). The conventional-conventional tillage system was found most effective to improve the biochemical characteristics of soil. Under this system, maximum organic C content was accumulated in rhizosphere soil and also found maximum enzyme activity (dehydrogenase activity, acidic phosphatase activity and alkaline phosphatase activity). Application of pre- and post- emergence herbicide reduced the biochemical activities in soil after its application (3 and 22 days after sowing, respectively) to 35 days of sowing of the crop thereafter it became normalize due to degradation of applied herbicides.

A field experiment was conducted at Varanasi to study the effect of different rates of carfentrazone-ethyl for controlling weeds in rice. Major weed flora were: Echinochloa colona, Echinochloa crussgalli, Dactyloctenium aegyptium, Caesulia axillaris, Ammania baccifera, Eclipta alba and Phyllanthus niruri. Application of carfentrazone-ethyl at 35 g/ha effectively reduced the density, dry matter accumulation and N, P, K depletion by weeds, and recorded the highest weed control efficiency. It also enhanced the growth parameters, grain and straw yield, nutrient uptake by the crop. Herbicides ethoxysulfuron at 15 g/ha, metsulfuron at 4 g/ha and carfentrazone at 15-35 g/ha applied as post-emergence and pendimethalin at 1.0 kg/ha as pre-emergence recorded higher values of yield attributes and yield.

Abstract:

Field and pot studies were conducted to determine the compatibility of dicamba in tank mix combination with sulfosulfuron and clodinafop against weeds of wheat (Triticum aestivum). Dicamba alone was effective against broad-leaf weeds only. No significant difference for broad-leaf weed control was observed between dicamba doses of 240 and 360 g/ha. Dicamba in combination with clodinafop and sulfosulfuron controlled the broad spectrum weed flora. The efficacy of dicamba in combination with clodinafop and sulfosulfuron was not affected for broad-leaf weed control. However, Phalaris minor control with clodinafop was reduced when dicamba applied as tank mix combination. The efficacy of sulfosulfuron was not affected by dicamba when applied as tank mixture and as a result this mixture (sulfosulfuron + dicamba 25 + 120 g/ha) had the highest wheat grain yield (4.99 t/ha). P. minor dry weight reduction with clodinafop 60 g/ha alone and in tank mix combination with dicamba 240 g/ha was 97.3 and 58.3%, respectively. In pot studies also, the tank mixing of dicamba did not affect the sulfosulfuron efficacy but clodinafop efficacy was significantly reduced against P. minor. The P. minor biomass reduction with clodinafop 30 and 60 g/ha was 84.8 and 99.6%, respectively and when dicamba 240 g/ha was added, the fresh weight reduction reduced to 62.6 and 78.6%, respectively, compared to untreated control.

Abstract:

An experiment was conducted during Rabi season of 2008-09 and 2009-10 at Varanasi (Uttar Pradesh) to evaluate the boiefficacy of carfentrazone-ethyl + sulfosulfuron in wheat. The experimental field was infested with Phalaris minor, Rumex dentatus, Chenopodium album, Anagalis arvensis and Melilotus spp during both the years of study. The result indicated that post-emergence application of carfentrazone + sulfosulfuron with surfactant at 45 g/ha recorded minimum density and dry weight of weeds and it was at par to 54 and 90 g/ha, without any phytotoxicity symptoms on the crop. Significant variation in wheat yield was recorded due to application of different herbicides when compared with control. Carfentrazone-ethyl + sulfosulfuron with surfactant at 45 g/ha recorded significantly the highest grain yield over its rate of 36 g/ha and it was at par to 54 and 90 g/ha. The regration equation indicated that extent of reduction could be 26.5 kg/ha for weed dry weight. The evaluation of weed dry weight and weed control efficiency of the different treatments and the regression of yield on it reveled that reduction in grain yield could be 0.025 t/ha for weed dry weight and 1% increase in the weed control efficiency increased the grain yield by 0.020 t/ha, respectively.

Abstract:

A field experiment was conducted during summer season of 2006 and 2007 under irrigated condition in a sandy loam soil at Sriniketan, West Bengal to determine the critical period of crop-weed competition in sesame. Results revealed that weed-free condition between 15 and 45 days after sowing (DAS) significantly increased the yield of sesame, whereas the lower yield of was recorded when weeds were allowed to grow during this period. The maximum competition between crop and weed was between 15 and 45 DAS, which can be considered as critical period of crop-weed competition. However, the extrapolated critical period was determined from 19-42 DAS. To avoid the yield loss, weed management should be done in such a time so that minimum weed infestation is achieved in summer sesame.

Abstract:

Parthenium  hysterophorus, is an annual herb that aggressively colonizes disturbed sites. In Pakistan, this weed is spreading very fast especially in north eastern parts of the province, Punjab. Due to lack of information on its spread, a survey was carried out in the district Rawalpindi where 8 sites were selected for sampling. The survey revealed very high density of P. hysterophorus at all sites and a total of 33 plant species were associated with P. hysterophorus. The relative density of weed in different sites of the district ranged from 8.2-64.5% while the relative frequency ranged from 14.2-29.6%. The extent of infestation was highest in denuded and fallow lands, especially in areas where soil has been disturbed. It was concluded that Parthenium is an extremely aggressive and prolific invasive weed in distract Rawalpindi and coordinated efforts are needed to manage this weed to stop its further spread.

Abstract:

Flora and fauna of Western Ghats, a biodiversity hot spot are under major threat due to various factors. Invasion of exotic species has been considered as one of the major threat in the area. In the present study, potential distribution of three obnoxious weeds, viz. Chromolaena odorata, Lantana camara and Parthenium hysterophorus was modeled using 32 environmental variables and MAXENT modeller. These three species showed distinct potential distribution patterns with only slight overlap between C. odorata and L. camara, and between L. camara and P. hysterophorus. Overlap of the former pair was seen mostly along the wet western slopes of Western Ghats, and latter along the eastern, rain shade dry areas. The environmental variables that contributed to the model showed that it was basically precipitation and temperature seasonality that defined their distribution. It was interpreted that the weeds might have adapted to different sets of environmental conditions throughout their distributional range; and hence, the variables operating in the study area contributing to the model may not be useful in predicting their presence elsewhere. It is concluded that to understand the full adaptability of these weeds, environmental variables can be studied at local levels and the results compiled for larger areas to get the full spectrum.

Abstract:

Adsorption–desorption of atrazine was measured in four soils of Hyderabad using batch equilibrium method at 27+1oC. The Freundlich equation was used to describe batch results. Both adsorption and desorption isotherms were well described by the Freundlich model. Fitted Kf value for desorption isotherms were consistently higher than those associated with adsorption. The opposite trend was observed for the exponential parameter n. The results revealed that the desorption data deviated significantly from adsorption data. The deviation, which is commonly referred to as hysteresis, was more prominent with higher adsorbed concentration of atrazine and incubation time. Desorption was significantly higher at the lowest adsorbed level of atrazine. The Freundlich Kf  and n values were higher than that for adsorption and increased with increase in initially adsorbed concentration of atrazine.

Abstract:

Weeds can be controlled effectively only when the management practices are employed at and early growth stage. Therefore, identifying weeds at seedlings stage is very essential for designing an efficient strategy for their management. However, it is a difficult task unless one has enough knowledge and experience. To help identifying weeds at seedling stage, an expert system has been developed at the Directorate. The expert system uses scientific name-based classification and a mix of the text description and images. The system is supported by a database containing information on 138 weed species with colour images of weed seedling at five growth stages. The expert system was evaluated following the conventional expert system evaluation methodologies. Results indicated that non-expert users were able to make weed seedling identification using the expert system more efficiently.

Abstract:

An experiment was conducted in randomized block design with 7 treatments comprising butachlor 1.5 kg/ha at 5-7 DAT, bispyribac-sodium 25 g ha at 15-20 DAT, bispyribac-sodium 35 g/ha at 15-20 DAT, bispyribac-sodium 50 g/ha at 15-20  DAT, weed-free, until harvest, two hand weedings at 20 and 40 days after transplanting and unweeded control. Results revealed that application of bispyribac-sodium 50 g/ha at 15-20 DAT resulted in significantly higher grain yield (5.70 t/ha), which was at par with bispyribac-sodium  35 g/ha at 15-20 DAT. Number and dry weight of weeds was also minimum in these treatments. However, the highest grain yield (6.05 and 6.55 t/ha) was obtained from weed-free treatment. Significantly lower weed density (9-10/m2), weed dry weight (12.5-13.7 g/m2), weed persistence index (0.03) and weed competition index (8.05-12.55) were recorded in the plots where bispyribac-sodium 35 g/ha at 15-20 DAT was applied. Significantly higher weed control efficiency and herbicidal efficiency index were recorded with bispyribac-sodium 35 g/ha at 15-20 DAT.

Abstract:

A field experiment was conducted at S.V. Agricultural College Farm, Tirupati to identify the effective and economic weed management practices for the control of weeds in drum seeded rice. The major weed flora in experiment field were Cyperus difformis (40.0%), Cyperus iria (21.40%), Cyperus rotundus (12.22 %), Echinochloa colonum (10.1%), Eclipta alba (6.5%) and Ammania baccifera (4%). Among the weed management practices, pre-emergence application of oxadiargyl 75 g/ha fb azimsulfuron 30 g/ha was found to be the most effective weed management practice in reducing the density and dry weight of weeds with higher weed control efficiency, higher yield attributes and yield (5.75 t/ha) including benfit : cost ratio (3.30) but it was being at par with two hand weedings. The reduction in grain yield due to heavy weed infestation in unweeded check was 51% compared to best weed management practice. Post-emergence application of azimsulfuron 30 g/ha was found effective in controlling sedges and bispyribac-sodium 30 g/ha was very effective in suppressing the grasses and broad-leaved weeds in drum seeded rice.

Abstract:

An average decrease in grain yield by 15.42 % was observed due to season-long weed-crop competition. Lowest monocot and dicot weeds were observed with weed free treatment. The best weed control efficiency in case of monocot (90.8%) and dicot (82.8%) was achieved with metsulfuron-methyl and metribuzin, respectively compared to other herbicides namely pendimethalin, carfentrazone, fenoxaprop and 2,4-D. All the treatments except fenoxaprop, carfentrazone, 2,4-D and mixture of metribuzin and fenoxaprop application gave significantly higher grain yield compared to weedy check. However , higher additional net return (Rs. 31,359) was obtained with metsulfuron-methyl followed by metribuzin (Rs. 30,907).
