  • 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:

A field experiment was conducted to study the effect of  irrigation and weed management practices of rice under aerobic culture, laid in split plot design. Among the irrigation schedules, IW/CPE ratio of 1.2 produced significantly higher stature of yield attributes, viz., total number of panicles/m2, total number of grains/panicle and number of filled grains/panicle and grain and straw yield were distinctly superior to other two irrigation schedules.  At all the  stages, with exception at 20 DAS, the lowest of density of weeds and  their corresponding dry weight was recorded with hand weeding at 20 and 40 DAS, which were comparable with oxadiargyl 0.07 kg/ha supplemented with HW at 40 DAS for density of grasses, triasulfuron 0.006 kg/ha supplemented with HW at 40 DAS for density of broad leaved weeds and bensulfuron methyl 0.06 kg/ha supplemented with HW at 40 DAS for density of sedges. The highest density of these entire weed categories was recorded with unweeded check. The study revealed that rice can be successfully grown under aerobic culture in north coastal zone of Andhra Pradesh, with pre-emergence application of oxadiargyl 0.07 kg/ha supplemented with HW at 40 DAS for higher productivity.

Abstract:

Spraying of foliar herbicide to control water hyacinth may lead to mortality of the fish by root exudation of herbicide or accidental drift of herbicide. To overcome herbicide-divalent cations complex formation in hard water at improper pH, increasing herbicide dosage per drop, either by increase of dosage or by reduce the spray volume, was one of the techniques. Using radioactive 14C-glyphosate and 14C-2,4-D, effect of dosage on herbicide retained on the cuticle as dried out residue, distribution with in plant system and moved out as root exudates was assessed. Twice the recommended concentration (2x) of herbicide per drop and drop density per fed spot significantly increased the dried residue on the cuticle 67 to 91 and 68 to 79% over total activity recovered compared to x dose for glyphosate and 2,4-D, respectively.  2,4-D (2x) significantly increased the amount of herbicide cuticle loading and mobility within cuticle but differences in translocation to different  parts was not significant except in root  (2x had lower activity than x). Similarly, significant difference between 2x and x for glyphosate was observed for cuticle loading and root exudates.  At 2x dosage, root exudates of both herbicides was more after 8 days. Half-life in pond water was around 5 days for both herbicides compared to normal water 7 and 11days of glyphosate and 2,4-D respectively. The chances of hherbicide toxicity to fishes were unlikely by foliar applied herbicides.

Abstract:

A field experiment was conducted at Pantnagar during winter season 2005-06 and 2006-07 to study effect of rates of herbicide mixture clodinafop-propargyl 15% + metsulfuron-methyl 1% (UPH-206) for control of mixed weed flora in wheat (Triticum aestivum L.). Grassy weeds such as Phalaris minor, Avena fatua and broad-leaved weeds, viz., Chenopodium album, Melilotus spp., Medicago denticulata, Vicia sativa, Rumex spp., Anagallis arvensis, Coronopus didymus, Lathyrus aphaca and  Polygonum plebejum  were effectively controlled by application of UPH-206  500 g product/ha. The highest grain yield (4.17 t/ha) of wheat was also obtained with the post-emergence application of UPH-206 500 g product/ha being at par with UPH-206 400 g product/ha, and hand weeding at 35 and 55 DAS, but significantly higher than sulfosulfuron, clodinafop and isoproturon at recommended rates. No residual effect of UPH 206 at any of doses tested was obtained on succeeding crops of blackgram and maize.

Abstract:

A field experiment was conducted in an Alfisol to study the degradation of butachlor and its residues in paddy grain during Rabi and Kharif seasons of 2007-08 at College Farm, College of Agriculture, Rajendranagar. Butachlor dissipated with half life varying from 12.5 to 21.5 days when applied at the rate of 1.0 and 2.0 kg/ha under with and without organic manures conditions. The observed half life values were lower for lower dose of applied herbicide as compared to higher dose and the field half life of butachlor was more under without organic manures as compared to organic manures applied plots. Residues of butachlor in field soil were analysed by using gas chromatograph and 100% dissipation of butachlor was observed at the time of harvest of crop.  Very low levels of residues were detected in rice grain below the maximum residue limit of 0.5 mg/kg. Therefore, application of butachlor in paddy for weed management can be considered safe from the point of consumption of grain.

Abstract:

A field experiment was carried out for two consecutive years during Kharif seasons of 2010 and 2011 to find out practically convenient and economically feasible weed management practice in onion at breeder seed production farm in Mahatma Phule Krishi Vidyapeeth, Rahuri. Different combinations of hand weeding with application of Pendimethalin 1.0 kg/ha (pre-planting) and oxyfluorfen 0.250 kg/ha (post-emergence) were used in onion variety ‘Baswant-780’. Weed free check treatment (three hand weeding at 20, 40 and 60 DAS) recorded significantly lowest weed density, dry weight of weed and higher weed control efficiency. All the growth attributes of onion viz., plant height, neck thickness, bulb weight and bulb diameter were recorded maximum in weed free. This treatment also recorded highest bulb yield and gross monetary return per hectare, however maximum B:C ratio was observed in treatment pendimethalin 1.0 kg/ha (PP)+ Oxyfluorfen 0.250 kg/ha (POE)+ One hand wedding at 40 DAS.

Abstract:

An experiment was conducted at Oilseeds Research Station, Jalgaon during 2007 to 2009 in order to control groundnut associated weed growing in Kharif season. An experiment was done with seven treatments of pre and post-emergence herbicides comprising weedy cheek and weed free check replicated thrice in randomized block design (RBD) on medium clay loam soils with pH 8.1. The various weeds observed in groundnut field during Kharif season were, Amaranthns viridus, Parthenium hysterophorus, Acalypha indica, Cyperus rotundus , Cynodon dactylon, Phyllanthus niruri, Commelina spp., Eragrostic sp., Celosia argenia and Euphorbia sp. Among the grasses, Cynadon dactylon was predominant and among the sedges Cyperus rotundus was predominant. Among the different herbicides, pre-emergence application of pendimethalin 1.0 kg/ha + post-emergence application of imazethapyr 75 gm/ha at 20 DAS recorded maximum weed control efficiency (74%), minimum weed population (42.67/m2) and weed day matter (185 g/m2). The same treatment combination recorded significantly higher dry pod yield (1997 kg/ha), gross returns (46445/ha) net returns (28705/ha) and B: C ratio 2.44.

Abstract:

A field experiment was conducted at Ranchi, Jharkhand during rainy seasons of 2010 and 2011 to find out the effect of seed rate and weed control methods on wet seeded rice under medium land condition.  Increasing seed rate from 60 to 120 kg/ha did not influence weed density and weed dry matter at 20 and 40 DAS. Application of pyrazosulfuron 0.02 kg/ha early post-emergence reduced density of all categories of weeds. The mean reduction was 61.9 and 35.3% and 66.7 and 41.9% at 20 and 40 DAS compared to butachlor and 2 hand weeding respectively. Pyrazosulfuron being similar to Almix (chlorimuron + metsulfuron) 20 g/ha recorded 70.3 and 87.0% reduced weed dry matter compared to weedy check. Application of 80 kg seed/ha being similar to 100, and 120 kg seed/ha recorded 63.0% higher grain (2.70 t/ha) and 70.9% higher straw (3.81 t/ha) yield compared to 60 kg seed/ha.

Abstract:

Technique enhancing herbicide entry into the plants leads to reduction in dosage and therefore pollution. Higher density of fine droplets along with surfactant increased the herbicide entry points, than coarse droplets for same total spray volume.  But fine droplets evaporate faster resulting in herbicide getting deposited as dried crystals on leaf surface. To overcome this problem, several adjuvants were tried to increase the time required for evaporation. Jaggery (2%) increased the evaporation period (27-162%) on different weed species. Dried out deposition of radioactive glyphosate from fine drops and along with TritonX 200 was more but showed enhanced glyphosate entry into the plant system. Whereas, aqueous extract (2%) of soap nut fruit (Sapindus emarginatus) which acts as bio-surfactant and antioxidant increases the time taken for drying and therefore enhances the translocation of glyphosate to bulb of O. latifolia, which was on par with TritonX 100 surfactant (petroleum product). This approach seems to be more beneficial than increasing the dosage of herbicide per droplet.

Abstract:

A field experiment was conducted at Chatha, Jammu during winter season of 2004-05 and 2005-06 to study the effect of different herbicides and its mixtures on weeds and yield of wheat (Triticum aestivum). Unchecked weeds growth caused 40.3% reduction in grain yield of wheat. Application of sulfosulfuron (25 g) + 2,4-D (500 g/ha) reduced weed population and  biomass significantly and thereby caused increase in crop growth and grain yield of wheat. This was at par with tank-mix application of clodinafop (60 g) + metsulfuron-methyl (2 g/ha), isoproturon (750 g) +2,4-D (500 g/ha) and fenoxaprop (120 g) + metribuzin (100 g/ha). Maximum grain yield was recorded in weed-free (5.05 t/ha), but the highest B:C ratio was observed with isoproturon+2,4-D (1.79). There was a significant positive correlation between N uptake by crop and grain yield of wheat (0.99), but a negative correlation was observed between grain yield and density and N removal by weeds.

Abstract:

A field experiment was conducted during Rabi seasons of 2006-07 and 2007-08 at Research Farm of GBPUA&T, Krishi Vigyan Kendra Dhakrani, Dehradun to study the effect of weed control practices on weed dyanamics, nutrient uptake and yield of wheat (Triticum aestivum (L.) emend. Fiori and Paol). Results revealed that application of clodinafop-propargyl + metsulfuron-methyl (60+4 g/ha) being on at par with clodinafop propargyl + 2,4-D (60+500 g/ha) reduced the weed population significantly over weedy check (97.2%) and other weed control treatments. Clodinafop-propargyl+ metsulfuron-methyl (60+4 g/ha) applied as post-emergence (35 DAS) recorded 14.3, 15.5, 23.7, 29.5, 45.9, 47.4 and 69.7 per cent more grain yield over pendimethalin, isoproturon + metsulfosulfuron-methyl, fenoxaprop-p-ethyl + metsulfuron-methyl, fenoxaprop-p-ethyl, isoproturon, clodinafop-propargyl and weedy check, respectively. The weeds removed the 28.7 kg of N, 13.4 kg P2O5 and 21.5 kg of K2O/ha, and reduced the wheat grain yield by 78.8% as compare to weed free conditions. Application of clodinafop-propargyl + metsulfuron-methyl reduced the nutrients removal by weeds and increased its removal by wheat.

Abstract:

A field experiment with 11 weed management practices including herbicide and hand weedings was conducted at Jagdalpur during 2006 and 2007. Digitaria sangunalis, Eleusine indica and Echinochloa colona among monocots, and Celosia argentia and Spilanthes acmella among dicots were the major weeds. Dry weight of weeds and weed control efficiency were the lowest under weed-free condition throughout crop growth period fb weed-free up to 40 and 50 DAS, and hand weedings at 20 and 40 DAS. These treatments also led to higher yield attributes and yields of finger millet. The highest B:C ratio (3.79) was obtained when isoproturon 0.5 kg/ha was applied as pre-emergence followed by its lower dose (0.05 kg/ha).

Abstract:

An experiment on evaluation of soil solarization on weed seed bank of soil was conducted in 2004 at College of Agriculture, Gwalior, in randomized block design with six non chemical agronomical weed management practices viz., solarized (45 days) non-solarized, stale seed bed, deep ploughing, green manuring and mulching by green biomass. The soil temperature recorded under solarized conditions were 43.90C and 43.80C at 10 and 15 cm depth and it was 4.60C and 4.50C higher than non-solarized soil respectively.  In solarized soil total number of grassy, broad leaved and sedges weeds waslowest, while highest grasses were reported in non-solarised soil. Total number of weeds was highest in non solarized soil followed by green manuring, stale seed bed, mulching, deep ploughing and non-solarised soil. Thus soil solarization was found to be the best non chemical agronomical practice for weed management methods used resulting to lowest weed seed bank.

Abstract:

A field experiment was conducted during Rabi season of 2009-10 at College of Agriculture, Pune to study the eficacy of different herbicides on growth and productivity of wheat. The growth  attributes of wheat crop in terms of plant height, number of tillers/plant, leaf area index, and dry matter accumulation/plant were maximum with weed free check. Among the herbicide treatments, post-emergence application of sulfosulfuron 25 g/ha recorded higher values of all these growth attributes characters and were on par with hand weeding at 30 DAS and application of metribuzin 175 g/ha. However, substantial reduction in growth characters was observed in weedy check. The values of yield attributes were higher in magnitude in weed free check treatment. The next best treatment was application of sulfosulfuron 25 g/ha. Amongst the weed control treatments, application of sulfosulfuron 25 g/ha, recorded maximum grain and straw yield of 3.71 and 4.78 t/ha, respectively, as compared to other treatments. However, substantial reduction in growth and yield attributes and yield were observed in weedy check.

Abstract:

A field experiment was carried out at Gwalior during Kharif season of 2010 to access the effect of weed management practices to sesame on seed yield and nutrient uptake by crop and weeds and net returns. Two hand weeding at 15 and 30 DAS registered highest yield (1190.22 kg/ha) and net return ( 42391/ha) in addition to higher NPK uptake by crop and lower NPK uptake by weed. Among herbicidal treatments application of trifluralin 0.75 kg/ha followed by one hand weeding at 30 DAS was found superior for yield, NPK uptake by plant and net return. Integration of herbicides viz., trifluralin, pendimethalin, quizalofop ethyl and clodinafop with one hand weeding at 30 DAS was found more effective as compared to their alone use. NPK removed by weeds was heighest in weedy check and lowest in two hand weeding followed by trifluralin 0.75 kg/ha integrated with one hand weeding at 30 DAS.

Abstract:

The study was conducted in Sinduri village of Shahdol district in Madhya Pradesh to evaluate rotary weeder’s ergonomic effectiveness in terms of energy requirement, subjective judgement of Work Related Body Discomfort (WRBD) and work performance in comparison with hand weeding.  Ergonomic results showed that the energy requirements for farm women were 16.0 and 11.04 kj/min for rotary weeder and hand weeding, respectively. The area covered by rotary weeder was 110 m2/hr as compare to 30m2/hr by hand weeding (nearly 4 times). The Overall Rated Perceived Exertion (ORPE) was used to express WRBD.  It was more in hand weeding due to continuous bending posture as against standing posture.

Abstract:

Field experiment was conducted to evaluate the efficacy of imazethapyr on weed control in soybean and its residual effect on succeeding crops. Early post-emergence application of imazethapyr reduced broad-leaved weeds and grass density as well as dry weight when compared with pre-emergence application of pendimethalin and oxyfluorfen. Imazethapyr at 200 g/ha decreased the dry weight accumulation of all weeds significantly followed by imazethapyr 100 g/ha. Due to phytotoxic effect at 200 g/ha during initial stages yield and yield attributes were get reduced. Imazethapyr at 100 g/ha was found best treatment by giving more seed yield. To study the residual effect of imazethapyr on succeeding crops, sunflower and pearl millet were grown without disturbing the soil. The residues of imazethapyr at different doses did not influence germination, growth, yield of sunflower and pearl millet and was statistically at par with checks.
