  • Style of Invited paper
  • Style of Research Article
  • Style of Research note

Format

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

Title

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

Author(s) name(s) and affiliations

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

Abstract

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

Key words

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

Introduction

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

Materials and Methods

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

Results and Discussion

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

Acknowledgement

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

References

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

Length

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

Units, abbreviations and nomenclature

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

Tables and figures

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

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

Some useful tips

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

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

Manuscript submission

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

Peer Review Policy

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

Paper Publication Process –

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

Peer Review Policy

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

Initial manuscript evaluation

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

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

Type of Peer Review

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

How the reviewer is selected

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

Reviewer reports

Reviewers are asked to evaluate whether the manuscript:

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

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

How long does the peer review process take?

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

Final report

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

Special Issues / Conference Proceedings

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

Becoming a Reviewer for the (Indian Journal of Weed Science)

Abstract:

Parthenium hysterophorus L., commonly known as carrot weed or congress grass in India has been considered as one of the worst weeds responsible for causing health problems in men and animals besides loss to crop productivity and plant biodiversity.  The weed has infested about 35 million hectares of land in India since its first notice in 1955. Now it has become one of the main weeds in almost all types of agricultural lands besides infesting wasteland, community land, road and railway track sides and forests. In an attempt of biological control, search for suitable bioagent began in 1980s in India through systematic surveys. The work on biological control through competitive plants was started with the search of Cassia sericea from south India which lead to more attempts to manage Parthenium by competitive plant species. Casia tora and C. sericea have been recommended most suitable plant species for management of Parthenium in wasteland, on the raod side and community land. Likewise, in spite of hundreds of reports of pathogens causing disease on Parthenium, none of them has qualified as successful bioagent. So far, attempts of developing effective mycoherbicides have not yielded any success. Not even a single indigenous insect species has proved successful in spite of occurrence and infestation by many species. Under classical bilogical control of Parthenium in India, three insect species were imported in 1983 from Mexico, out of which only host-specific leaf-feeding beetle Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae) was proved successful. Z. bicolorata has established in many parts of the country and has been found responsible to decrease the Parthenium densities in different parts of India. This paper gives details of current status of biological control of Parthenium and future strategies in India.

Abstract:

A field experiment was conducted at the Crop Research Centre of RAU, Pusa, Bihar during Kharif 2006 and 2007 to evaluate the comparative efficacy of herbicides fenoxaprop-p-ethyl with standard doses of quizalofop and pendimethalin to control grassy weeds in jute grown for seed production.  Losses in seed yield in control plot were observed 63.4% in comparison to hand weeding twice. Weed species count at 40 and 60 days after sowing (DAS) was found lowest in fenoxaprop-p-ethyl at 67.5 g/ha treated plot while seed yield was higher in the  fenoxaprop-p-ethyl at 56.25 g/ha. Morpho-physiological attributes of jute viz., plant height, base diameter, number of capsules per plant, 1000 seed weight and seed yield were  found significantly higher in fenoxaprop-p-ethyl at 56.25 g/ha which showed at par with quizalofop at 62.5 g/ha among the herbicidal treatments. The highest weed control efficiency was observed in fenoxaprop-p-ethyl at 67.5 g/ha but yield attributes and yield were found higher in fenoxaprop-p-ethyl at 56.25 g/ha. The study also revealed post emergence herbicides-fenoxaprop-p-ethyl and quizalofop more effective than pre emergence herbicides pendimethalin in controlling the weeds in jute.

Abstract:

A study on crop-weed competition in field pea comprising of weedy and weed-free conditions upto 30, 60 and 90 days after sowing and at harvest was conducted at the experimental research farm of Pulses Research sub-station, Samba, SKUAST,  Jammu during Rabi seasons of  2003-04 and 2004-05 to find out the critical period of crop-weed competition in field pea. Weed competition index increased with an increase in duration of weedy condition ranging from7.3 to 42.0 during Rabi 2003-04 and 1.19 to 56.3 during rabi 2004-05. On the other hand, increase in weed-free period from sowing to harvest decreased weed competition index from 2.9 to 42.0 during Rabi 2003-04 and 4.3 to 22.0 during 2004-05. Weed free condition beyond 60 days after sowing did not bring significant improvement in field pea seed yield. The highest additional net return (Rs. 2040/ha) and additional net return/rupee invested (0.35) were kept weed free upto 60 days after sowing. The critical period for crop-weed competition was observed to be between 30-60 days after sowing when the crop should be kept free from weeds to prevent the potential yield loss and to economize weeding in field pea.

Abstract:

Microbial activity and population dynamics of bacteria, fungi, actinomycetes, Azotobacter and phosphate solubilizing fungi (PSF) following application of butachlor was studied in a black cotton soil. Microbial population declined significantly due to butachlor treatment. Total population of fungi showed relatively more susceptibility than bacteria to butachlor.  At recommended dose, the toxic effect of butachlor on total bacteria disappeared by 30 days after application (DAA), but the soil could not regain its lost population of Azotobacter, total fungi and PSF during the study period of 45 days. Total microbial activity in terms of CO2 evolution from the soil sharply decreased by butachlor. Addition of glucose at 10 mg/kg soil nullified the adverse effect of butachlor on total microbial activity.

Abstract:

An experiment was conducted to study the production potential of rice under varying population densities of barnyard grass (Echinochloa crusgalli). There was a significant reduction in plant height, dry matter production as well as in yield by rice plant with increasing population density of barnyard grass from 25 plants/m2 to 250 plants/m2 because weed plants compete for growth factors like light, nutrients and space, etc. The reduction in dry matter was to the tune of 35.76, 32.26 and 35.80% in 250 plants of barnyard grass as compared to pure rice crop in 2005 and 52.11, 45.56 and 44.41% in 2006, respectively. A decreasing trend in panicle length, number of grains per ear, 1000 grain weight, grain and straw yield were observed as plant density of barnyard grass increased from 25 plants/m2 to 250 plants/m2 during both the years of investigations. At higher densities of barnyard grass, there was a gradual increase in dry matter production. Hence there was more suppression of rice crop at higher weed densities which resulted in significant reduction in grain yield of rice crop.

Abstract:

Effect of rice residue management practices (removal, burning and incorporation), weed control measures (weedy check and herbicide) and nitrogen levels (60, 120 and 180 kg/ha) on the weed infestation, wheat yield and fertility status in a swell-shrink black cotton soil was studied during 2003-06.  The herbicide treatment included application of isoproturon 1.0 kg/ha in the 1st year and tank mix of isoproturon 0.75 kg + 2,4-D 0.5 kg per hectare during the subsequent years.  Residue incorporation reduced weed density, especially of Phalaris minor, resulting highest wheat yield during 2nd and 3rd year.  Residue incorporation gave highest net monetary return of Rs. 57781 followed by Rs. 51440 and Rs. 48081 per hectare in the burning and straw removal treatments, respectively.  The highest B:C of 6.79 was also recorded in the residue incorporation treatment followed by 6.19 and 3.86 in the burning and straw removal treatments, respectively.  Herbicide application increased wheat yield and the net monetary return (B : C ratio).  Irrespective of straw management practices, no increase in wheat yield was recorded beyond the N dose of 120 kg/ha. Compared to burning, the incorporation of rice straw significantly increased the organic C, and the bacterial and fungal population in soil.  It was concluded that rice straw incorporation 5 t/ha was best among the given straw management practices in terms of weed density reduction, improved soil health, increased wheat yield, monetary return and B : C ratio.

Abstract:

A field experiment was carried out at Ludhiana during winter 2007-2008 to find out effective and safe herbicides for radish (Raphanus sativus L.). Pre-emergence herbicides viz., pendimethalin (0.37, 56 and 0.75 kg/ha), trifluralin (0.6, 0.9 and 1.2 kg/ha), alachlor (1.25, 1.87 and 2.5 kg/ha), oxyfluorfen (0.117, 0.147 and 0.176 kg/ha), vis-a-vis, two hand hoeing (20 and 40 days after sowing) and unweeded control were evaluated. Uncontrolled weeds reduced the radish root yield by 10.7 to 27.1%. All the herbicidal treatments significantly reduced weed density and dry matter. Trifluralin 1.2 kg/ha recorded the highest radish root yield and was at par with trifluralin 0.9 kg, pendimethalin 0.75 kg, alachlor 1.25 and 2.5 kg, oxyfluorfen 0.147 and 0.176 kg/ha and two hand hoeing. The herbicides did not influence the total soluble solids and isothiocyanate content in radish roots. Herbicide residues in crop roots were below detectable level.

Abstract:

Field experiments were conducted to find out the effectiveness of dual cropping of green manure crops, its methods of incorporation and levels of nitrogen on weed management and to study the cost effectiveness of the system of dual cropping of green manure crop in semi-dry rice. Among the two green manure crops, cowpea (Vigna unguiculata (L.) Walp.) was more effective in suppressing weeds and recorded the minimum weed population and weed dry matter compared to horse gram (Macrotyloma uniflorum (Lam) Verdc). Incorporation of green manure crops with 2,4-D significantly reduced weed population and weed dry weight compared to other incorporation methods. Nitrogen application at different levels had no significant influence on weeds. Dual cropping of cowpea and its incorporation at 45 days after sowing using 2,4-D was able to meet 25% N requirement beside reducing the weeds in semi-dry rice with increased productivity and profitability

Abstract:

Mass production of mycoherbicidal agent Sclerotium rolfsii (FGCC#02) under solid substrate fermentation was standardized. Mycoherbicidal potential of inoculum, grown on twenty agro wastes, applied on Parthenium at pre-emergence and post emergence stage was determined. Wheat grains and host leaves colonized inocula incited severe infection and was responsible for significant mortality at pre-emergence application while tea-bagasse-wheat bran-wheat straw (TBWW) was highly effective at post emergence stage. Contrary to these, waste cotton failed to cause appreciable mortality at both the stages.

Abstract:

A field experiment was conducted for two consecutive wheat seasons of 2005-06 and 2006-07 at crop research centre, GBPUA&T, Pantnagar on sandy loam soil to find out the effect of establishment methods and weed management practices on weed dynamics and productivity of wheat grown after harvesting of rice. Wheat was infested with Phalaris minor, Melilotus indica, Medicago denticulate, Chenopodium album and Rumex acetosella in weedy check at 60 days after sowing (DAS). Zero till sown wheat had significantly lesser infestation of all weeds except Rumex acetosella than other wheat establishment methods. Hand weeding twice at 35 and 55 DAS was most effective to minimize the weed density and their dry weight under all the wheat establishment methods. Zero till sown crop led to recorded significantly higher grain yield than other establishment methods, however, hand weeding twice was most effective in increasing the grain yield.

Abstract:

A field experiment was conducted to evaluate the bio-efficacy of new herbicides AEF 046360-8% EC and DIC 1468-14-22% EC alone and in combination at different doses against the complex weed complex in wheat crop. Wheat crop was mainly infested with grassy weeds like Avena ludoviciana, Phalaris minor and broad leaf weeds viz., Coronopus didymus, Anagallis arvensis, Melilotus spp. And Chenopodium album. Combined application of AEF 046360-8% EC and DIC 1468-14-22% EC (100+175 g/ha) was found effective against all the weeds as shown by the the lowest weed density of grassy as well as broad leaf weeds. AEF 046360-80% had better control over grassy weeds, whereas, DIC 1468-14-22% EC was found effective against broad leaf weeds. The highest grain yield was obtained with the application of AEF 4630-8% EC+ DIC 1468–14-22% at (100 + 175 g/ha) and was found at par with application of sulfosulfuron and AEF 4630-8% EC + DIC 1468-14-22% EC with their lower doses (80 + 140 g/ha).

Abstract:

A field experiment was conducted to study the efficiency of different weed management interventions in improving the carrying capacity of tiger grass (Saccharum spontaneum L.) infested pastures existing on riverbed deposits during 2002-03 to 2004-05 with nine treatment combinations comprising of manual eradication, glyphosate application 0.75 and 1.0% and agrostological interventions with 3 grass species in a randomized complete block design with three replications. After three years of treatment imposition, it was found that the application of either 0.75 or 1.0% glyphosate followed by planting either of napier hybrid (NB-21) or Cenchrus ciliaris was found equally effective in establishing a good grass cover as compared to Setaria as well as in smothering the regenerated growth of Saccharum plants resulting in reduction of its fresh biomass to 9.02-13.0 q/ha i.e. less by 90-94% as compared to its initial biomass of 116 q/ha which in turn was statistically similar to manual eradication of this weed. However, the application of glyphosate 0.75% on the regenerated growth of spring shaven Saccharum just before rainy season followed by planting of napier cuttings or Cenchrus ciliaris Rooted slips was found to be economically better with a net saving of Rs 500 and Rs 13970 over all the other similar treatment combinations of 1% glyphosate as well as manual eradication, respectively, besides a sizeable enhancement in forage yield.

Abstract:

A field experiment was conducted to evaluate the bio-efficacy of azimsulfuron 50 DF against sedges especially Cyperus rotundus. As dose of azimsulfuron was increased from 25 to 30 g/ha, weed density and dry weight of weeds reduced at all the crop growth stages. Azimsulfuron was found comparable to pendimethalin and metsulfuron-methyl (MSM) alone but recorded significantly higher weed dry matter as compared to pendimethalin fb MSM at 45 DAS. Pendimethalin alone and azimsulfuron (30g) combined with MSM were comparable to standard check i.e. pendimethalin 1 kg/ha fb MSM 4 g/ha in terms of weed dry weight at 70 DAS. Azimsulfuron 30 g/ha along with MSM 2 g/ha recorded significantly higher yield (554 kg/ha) as compared to 25 g/ha along with MSM. There is no advantage of tank mixed application of azimsulfuron with MSM over azimsulfuron alone for the control of sedges and broad leaved weeds.

Abstract:

An experiment was conducted during kharif 2003 at Post Graduate Institute Farm, Mahatma phule Krishi Vidyapeeth, Rahuri in randomized block design with three replications and nine treatments. Weed intensity and weed dry matter at harvest was significantly less in weed free treatment followed by fluchloralin as pre-planting incorporation (PPl) 1.0 kg/ha plus glyphosate at 45 days after sowing (DAS) were in second order. Whereas, weed intensity and weed dry matter was maximum in weedy check treatment (206.57 m2 and 12.22 q/ha respectively). Dicot weeds were found higher in proportion than monocot weed. The weed control efficiency and weed index were influenced by various treatment. It was higher (75.64%) weed control efficiency and lower (14.06%) weed index in pendimethalin PE 1.0 kg/ha plus glyphosate 1.0 kg/ha at 45 DAS as compared to other treatments except weed free treatment. Beneficial effect due to above treatments on growth characters resulted in enhanced yield. Maximum values of yield attributes were observed in weed free treatment followed by IWM treatments viz., pendimethalin PE 1.0 kg/ha plus hand weeding at 45 DAS, two hand weeding at 20 and 45 DAS and pendimethalin PE 1.0 kg/ha plus glyphosate 1.0 kg/ha at 45 DAS. The seed yield of pigeonpea (22.98 q/ha) and stick (65.03 q/ha) was maximum in weed free treatment followed by IWM treatment viz., pendimethalin 1.0 kg/ha plus hand weeding at 45DAS

Abstract:

Field experiments conducted consecutively for four years (2002-2005) during kharif at OUAT Research Farm in upland condition revealed that recommended practice (butachlor 1.0 kg/ha + HW at 25 DAS) produced significantly higher grain and straw yield of 3767 and 4980 kg/ha, respectively. The same treatment also registered higher net return of Rs. 8070/ha with B:C ratio of 1.55. Population of grasses, broad leaf and sedges were lowest at 60 DAS where recommended practice (butachlor 1.0 kg/ha along with one hand weeding at 25 DAS) was followed. Weed control efficiency was found to be maximum (86.2%) in farmer’s practice (HW at 25 and 45 DAS) at 60 DAS.

Abstract:

Experimental site constituted by monocot weeds viz., Brachiaria spp. Echinochloa colonam L. Cav. dicot weeds viz., Amaranthus viridis, Digeria arvensis, Chenopodium album and Euphorbia hirta L. and sedges viz., Cyperus rotundus L. Integration of pendimethalin as pre-emergence (PE) with clodinafop, metsulfuron-methyl and 2,4-D amine salt post emergence with or without hand weeding proved effective in reducing weed density and dry weight of weeds. Significantly the higher yield attributing characters were recorded under weed free, closely followed by pendimethalin 0.9 kg/ha as pre emergence followed by one hand weeding at 35-40 DAS. The maximum net return was obtained under pendimethalin 0.9 kg/ha as pre-emergence + 1 HW at 35-40 DAS and which was closely followed by pendimethalin 0.9 kg/ha PE + clodinafop 60 g/ha as post emergence at 35-40 DAS.
