Guidelines for Authors

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.

Format

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

Title

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

Author(s) name(s) and affiliations

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

Abstract

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

Key words

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

Introduction

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

Materials and Methods

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

Results and Discussion

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

Acknowledgement

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

References

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

Length

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

Units, abbreviations and nomenclature

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

Tables and figures

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

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

Some useful tips

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

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

Peer Review Policy

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

Paper Publication Process –

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

Peer Review Policy

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

Initial manuscript evaluation

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

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

Type of Peer Review

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

How the reviewer is selected

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

Reviewer reports

Reviewers are asked to evaluate whether the manuscript:

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

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

How long does the peer review process take?

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

Final report

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

Special Issues / Conference Proceedings

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

Maximum depth of emergence of P minor was 5.92 cm under conventionally tilled wheat sown after transplanted rice, whereas minimum depth of 0.91 cm was recorded in zero tillage wheat after direct seeded rice without puddling (DS). Maximum P minor population emerged from 0-3 cm depth under all the wheat establishment methods. In both conventionally tilled and zero tilled wheat after direct seeded unpuddled and puddled rice, there was no emergence of P minor from 6-9 cm depth but still 5% population could emerge from this layer after transplanted rice. Conventionally tilled wheat had more weed population than zero tilled wheat after any rice establishment method. Under conventionally tilled wheat field before irrigation, there was 16% increase in P minor density during 15 to 20 DAS but after first irrigation, the density of this weed increased by 175% during 20 to 40 DAS. In zero tilled wheat, the density of this weed increased by 61% before irrigation and after irrigation this increase was only 102%. Email Address G. B.

The highest weed density and dry matter production were recorded in DSR (dry direct seeding unpuddled) and least in WSR (wet seeding in puddled soil) and TPR (transplant) establishment methods at 30 days stage of growth. In weedy plots, the density of Echinoch!oa colona in DSR was higher than in WSR and TPR. Similarly, nongrassy weeds were more in number in DSR than in WSR and TPR. The population of sedges was more in DSR than in WSR, whereas it was not found in TPR. Uncontrolled weeds, on an average, caused 75.8, 70.6 and 62.6% reduction in grain yield of rice when compared with weeded situation in DSR, WSR and TPR, respectively. Thus, the potential yield loss due to weeds was higher in DSR than in TPR. The grain yield of rice was similar under the three establishment systems of rice when weeds were controlled effectively by herbicide application supplemented with weedings. Email Address G. B.

Abstract:

Clodinafop-propargyl was compatible with metsulfuron-methyl and carfentrazoneethyl as tank mixture with respect to the control of Phalaris minor and Chenopodium album in wheat. Fenoxaprop-p-ethyl was compatible with carfentrazone-ethyl and not with metsulfuron-methyl. Clodinafop as well as fenoxaprop had no compatibility with 2, 4-D. The mixed population of P. minor and C. album caused 66% reduction in wheat grain yields in weedy plots, whereas competition with C. album caused 22% reduction in wheat yield.

Abstract:

Tank mixture of clodinafop+sulfosulfuron (3 : I) at 60 g ha- ' and fenoxaprop+ sulfosulfuron (4 : I and 5 : I) at 120 g ha- I provided 85-90% control of Avena ludoviciana and Phalaris minor and 60% control of broadleaf weeds like Chenopodium album. Melilotus indica and Rumex retrojlexus. None of the herbicide combinations was effective against Convolvulus arvensis. Clodinafop+sulfosulfuron at lower dose of 50 g ha- I and fenoxaprop+sulfosulfuron at 100 g ha- I although provided good control of broadleaf weeds but poor control of grassy weeds. Maximum grain yield (5240 kg ha- ') was obtained in weedfree treatment which was at par with clodinafop+sulfosulfllron (3 : I) at 60 g ha- I and fenoxaprop+slllfoslllfuron (4 : I or 5 : I) at 120 g ha- ' .

Abstract:

Fenoxaprop at 120 g ha", clodinafop at 60 g ha" and sulfosulfuron at 25 g ha" significantly reduced the density of Phalaris minor and increased number of spikes and grain yield of wheat over their lower doses. Density of broad leaf weeds decreased significantly with sulfosulfuron or metribuzin or tank mixture of metribuzin with fenoxaprop or c1odinafop compared to weedy check. Tank mixture of clodinafop+metribuzin at 45+ 140 g ha'I recorded lowest weed biomass fotlowed by fenaxoprop+metribuzin at 90+ 140 g ha'i and clodinafop+metribuzin at 30+140 g ha". Increasing the dose of metribuzin in the mixture from 100 to 140 g ha'i reduced wheat yield; the effect was more pronounced with fenoxaprop than with clodinafop.

Abstract:

Addition of power activator increased the efficacy of fenoxaprop-p-ethyl at 80 and 100 g ha- ' on grassy weeds in wheat. The efficacy of this herbicide at 120 g ha- ' was not affected due to addition of surfactant. Fenoxaprop at 100 g ha- ' with or without surfactant produced wheat grain yields at par with weed-free treatment and clodinafoppropargyl at 400 g ha- ' .

Abstract:

Dithiopyr at 360 g ha- I proved superior in reducing the density of Phalaris minor than the lower doses and was at par with trifluralin at 1250 g ha-' and isoproturon at 1000 g ha- I. Density of broad leaf weeds was significantly lower in the plots treated with dithiopyr at 240 g ha- 1 compared to trifluralin at 1250 g ha- 1 • Tank mixture of dithiopyr+isoproturon at 120+ 1000 g ha- 1 reduced the total dry weight of weeds by more than 90% over weedy check and provided similar yield to that of isoproturon and weed-free treatment. It was observed that at higher dose (480 g ha- I) of dithiopyr crop lodged due to thin stem and increased length of internodes.

Abstract:

Alone application of chlorsulfuron at lower doses (20 and 30 g hao' ) was not effective against Phalaris minor but it was at par with sulfosulfuron in reducing the broad leaf weeds at lowest (20 g hao' ) dose. Tank mixture of chlorsulfuron either with pendimethalin or tritluralin at 1430+70 g ha" provided effective control of both P. minor and broad leaf weeds. The number of spikes and wheat yield increased with the increase in dose of chlorsulfllron from 20-40 g ha· ' . Tank mixture of pendimethalin or tritluralin with chlorslllfllron did not increase grain yield of wheat over their alone application at corresponding doses.

Abstract:

Sulfosulfuron (except at 100 g ha- ' ) did not control wild oat population but reduced its dry matter significantly as compared to isoproturon and weedy check. Sulfosulfuron (either of its doses) was not effective against C(chorill/ll illtybus but gave effective control of Phalaris minor and Medicago hispida. Isoproturon was less effective against wild oat but gave very good control of C. album. Sulfosulfuron at 50 and 100 g ha- ' was phytotoxic to wheat crop during 2001-02. Isoproturon (1000 g ha- ' ) gave the maximum grain yield of wheat in absence of wild oat, while sulfosulfuron (50-100 g ha") in presence of wild oat.

Abstract:

Key weed species in the experimentaJ field were Phalaris minor, Avena ludoviciana, Chenopodium album. Melilotus indica. Coronopus didymus and Convolvulus arvensis. On an average, prometryn at 2.0 kg ha· 1 provided 73-82% control of grassy as well as broad leaf weeds. Efficacy of prometryn against grassy weeds was higher than isoproturon but lower than clodinafop and sulfosulfuron. Inspite of good efficacy of prometryn against weeds, wheat grain yield and number of spikes were significantly less than clodinafop and sulfosulfuron due to toxicity to crop.

Abstract:

Depth and periodicity of Phalaris minor emergence were recorded in wheat sown under different establishment methods after rice which was also planted adopting various establishment methods. Maximum depth of emergence of P minor was 5.92 cm under conventionally tilled wheat sown after transplanted rice, whereas minimum depth of 0.91 cm was recorded in zero tillage wheat after direct seeded rice without puddling (DS). Maximum P minor population emerged from 0-3 cm depth under all the wheat establishment methods. In both conventionally tilled and zero tilled wheat after direct seeded unpuddled and puddled rice, there was no emergence of P minor from 6-9 cm depth but still 5% population could emerge from this layer after transplanted rice. Conventionally tilled wheat had more weed population than zero tilled wheat after any rice establishment method. Under conventionally tilled wheat field before irrigation, there was 16% increase in P minor density during 15 to 20 DAS but after first irrigation, the density of this weed increased by 175% during 20 to 40 DAS. In zero tilled wheat, the density of this weed increased by 61% before irrigation and after irrigation this increase was only 102%.

Abstract:

Dry matter of Phalaris minor recorded at the time of harvest was found to be 100~er in the wheat crop sown after giving deep/inverted tillage with mould board plough dUring the start of the experiment and consequently the number of seeds of P minor in the top 0-15 cm soil depth was found to be significantly less in these treatments as compared to the plots of continuous zero till sown crop for three years. Post-emergence application of clodinafop 60 g ha- I, sulfosulfuron 25 g ha- I and fenoxaprop-p-ethyl 100 g ha,l was found to be at par with respect to dry matter accumulation by P minor. However, seed bank recorded during the year of termination was found to be significantly less in clodinafop, sulfosulfuron as compared to fenoxaprop-p-ethyl treated plots. Wheat sown after giving inverted tillage (during 2001-02) produced significantly higher grain yield as compared to the crop sown with zero tillage or zero tillage followed by normal tillage.

Abstract:

Puddling of soil significantly influenced the vertical distribution of weed seeds. Weed seeds were observed upto 20 cm depth but their intensity varied. While Chenopodium alhum was distributed mostly upto 5 cm depth, Medicago hispida and Phalaris minor were found in large numbers upto higher depth (10 cm). Avena ludoviciana was mostly abundant from surface to shallow depth (2.5 cm). Maximum emergence of P minor at 2 cm and A. ludoviciana at 4 cm depth was recorded upto two weeks. Red light increased the germination of P minor but reduced the germination of M. hispida. Lowest germination of Asphodelus tenuijblius and P minor was observed in dark but there was no effect of darkness on germination of M. hispida. Maximum germination of A. lucloviciano was recorded in green light.

Abstract:

Weed density and yield of rice in western IGP were examined in transplanted rice crop under rice-wheat, rice-pea-rice and rice-sugarcane=ratoon-wheat/fallow cropping systems. Echif/ochloa crusgalli was dominant after rice-wheat and rice-pea-rice sequence, but it was completely suppressed after the sugarcane sequence. Among sedges, Fimbristylis milliacea was dominant after rice-wheat and Cyperus difJormis after rice-pea-rice. [n the sugarcane system. Cyperlls rotllf/dlls became the main weed. The yield loss from weeds in unweeded plots was highest in the rice-wheat system. followed by rice-pea-rice, and was least in the sugarcane system. Under fanners' weed management practices, there were yield losses due to weeds ranging from 13.1 to 22.4'Yo. The total cost of weed management in transplanted rice was higher in rice-wheat system than in rice-pea-rice or rice-sugarcane system.

Abstract:

Rice establishment methods had marked effect on weed density and their dry matter production. The highest weed density and dry matter production were recorded in DSR (dry direct seeding unpuddled) and least in WSR (wet seeding in puddled soil) and TPR (transplant) establishment methods at 30 days stage of growth. In weedy plots, the density of Echinoch!oa colona in DSR was higher than in WSR and TPR. Similarly, nongrassy weeds were more in number in DSR than in WSR and TPR. The population of sedges was more in DSR than in WSR, whereas it was not found in TPR. Uncontrolled weeds, on an average, caused 75.8, 70.6 and 62.6% reduction in grain yield of rice when compared with weeded situation in DSR, WSR and TPR, respectively. Thus, the potential yield loss due to weeds was higher in DSR than in TPR. The grain yield of rice was similar under the three establishment systems of rice when weeds were controlled effectively by herbicide application supplemented with weedings.

Abstract:

Pre-emergence application of pretilachlor with safener supplemented with one hand weeding at 40 days after sowing provided better weed control and higher grain yield than the two hand weedings done at 20 and 40 days after sowing. Intercropping of Sesbllnia aeu/eala and dual cropping of azolla with rice resulted in reduced density and dry weight of weeds. Regarding nitrogen management, 100% N+S. lIeu/eala intercropping+azolla dual cropping had a positive impact on yield attributes and thereby produced higher grain yield.

Abstract:

Crop rotation of l1lustard-wheat-wheat-mustard was most effeclive in arresting populalton of Asphodelus tenuifolius with similar effect on weed dry weight. As a result. It improved yield attributes and seed yield of mustard by 667 kg ha" compared with continuous mustard rotation. The herbicidal control (tluchloralin at 1.0 kg ha" in mustard and 2. 4-D at 0.5 kg ha" in wheat) in mustard-wheat-wheat-mustard rotation controlled A. tenuifolius and total weeds effecltvely and thus significantly enhanced the seed yield of mustard. On the contrary, use of tluchloralin alone without any herbicide rotation in continuous mustard did not control A. tenuifolius effectively and thereby, reduced the seed yield of mustard compared to all other rotations.

Abstract:

Adsorption-desorption of sulfosulfuron on four Indian hill soils was studied using batch equilibrium technique. Freundlich constant log K was highest for mollisol-2 soil having low organic carbon, clay content and high pH. Adsorption was in the order inceptisol > mollisol-2 > mollisol-I > entisol. Sulfosulfuron showed S-type adsorption isotherm curves indicating hydrophilic nature of surface of soils due to which water molecules compete with the herbicide. Sulfosulfuron showed negative hysteresis or irreversiblc adsorption with hysteresis coefficient values more than I.
