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

Format

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

Title

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

Author(s) name(s) and affiliations

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

Abstract

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

Key words

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

Introduction

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

Materials and Methods

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

Results and Discussion

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

Acknowledgement

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

References

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

Units, abbreviations and nomenclature

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

Tables and figures

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

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

Some useful tips

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

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

Manuscript submission

Manuscripts must conform to the journal style (see the latest issue). Correct language is the responsibility of the author. After having received a contribution, there will be a review process, before the Chief Editor makes the definitive decision upon the acceptance for publication. Referee's comments along with editors comments will be communicated to authors as scanned copy/soft copy through email. After revision, author should send back the copy of revised manuscripts to the Chief Editor, ISWS by e-mail only.

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

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

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

Peer Review Policy

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

Paper Publication Process –

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

Peer Review Policy

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

Initial manuscript evaluation

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

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

Type of Peer Review

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

How the reviewer is selected

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

Reviewer reports

Reviewers are asked to evaluate whether the manuscript:

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

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

How long does the peer review process take?

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

Final report

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

Special Issues / Conference Proceedings

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

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

Abstract:

Growth cabinet studies were conducted on the effect of temperature, pH and light exposure on seed germination of Brazil pusley, common ragweed, Florida beggarweed, hairy beggarticks, ivyleaf morningglory, Johnson grass, prickly sida, redroot pigweed, sicklepod, strangler vine, tall morningglory and yellow nutsedge. When averaged over all species and temperatures, highest weed seed germination was recorded in the temperature regime of 25 to 35OC, maximum being at 30OC. Lower temperature of 15OC inhibited germination of Johnson grass, Brazil pusley, Florida beggarweed, redroot pigweed, prickly sida and yellow nutsedge. Germination of common ragweed and ivyleaf morningglory was highest at 20OC, and significantly decreased above 35OC. Higher temperatures (30 to 40OC) were less inhibitory to germination of redroot pigweed, Johnson grass, Florida beggarweed, prickly sida and yellow nutsedge compared to other weed species. Tall morningglory and hairy beggarticks had high germination rates from 15 to 35OC. Germination of prickly sida and Florida beggarweed was highest between 25 to 40OC and sicklepod from 20 to 40OC. Strangler vine germination was highest at 30OC and decreased significantly with any increase or decrease in temperature. No weed seed germinated at pH 3, except yellow nutsedge. A pH range of 5 to 11 had no adverse effect on germination, when data were averaged over species. Germination of prickly sida was highest at pH 9 and any increase or decrease in pH resulted in reduced germination. Yellow nutsedge seed germinated 14% at pH 3 compared to 47% at pH 7. Germination was not inhibited for any test species in dark, except Brazil pusley. After 168 h, germination of Brazil pusley ranged from 2 to 10% with light exposure of 0 and 16 h, respectively, before placing them in dark. Under alternate light and darkness cycle of 12 h, germination of Brazil pusley increased to 59%. Other than Brazil pusley no other species exhibited the photoblastic effect.

Abstract:

Laboratory experiments were conducted to study germination, emergence and establishment of yellow sweet clover (Melilotus indica). The seeds showed poor germination in Petri dishes due to a hard seed coat. Mechanical scarification, acid scarification and scarification by a short term exposure (4-5 min) to boiling water resulted in 100% germination of 1-, 2- and 3-year old seeds. Seedling emergence from non-scarified seeds was observed within 15 days. The emergence from surface sown seeds in pots was >80% and the emergence declined significantly with an increase in the seeding depth. Germination percentage, hypocotyl and radical growth of seedlings from seeds scarified by boiling were not inhibited by an osmotic potential upto -0.8 MPa .The growth was, however, inhibited by a salt stress of 40 mM NaCl indicating that the species is drought tolerant and salt sensitive. Plant growth was slow during the initial 60 days i. e. from November end to January end. The information could be exploited for developing strategies for the management of this weed.

Abstract:

Growth cabinet studies were conducted on the effect of water potential and interaction of temperature and water potential on germination of Brazil pusley, common ragweed, Florida beggarweed, hairy beggarticks, ivyleaf morningglory, Johnsongrass, prickly sida, redroot pigweed, sicklepod, strangler vine, tall morningglory and yellow nutsedge. Decreasing water potential from 0 to -0.1, -0.2 -0.4 and -0.8 MPa caused 12, 32, 75 and 96% reduction in germination of the test species, 3 WAS. A lower water potential of -0.1 MPa resulted in significant reduction in germination of common ragweed, strangler vine, hairy beggarticks and redroot pigweed. Decreasing water potential further to -0.4 MPa caused 77 to 100% inhibition in germination of all the test species, except Florida beggarweed, yellow nutsedge and tall morningglory. No weed seed could germinate at -1.2 MPa, whereas 28, 9 and 3% seeds of Florida beggarweed, yellow nutsedge and tall morningglory were able to germinate at -0.8 MPa. Water stress of -0.1 and -0.2 MPa delayed the germination of Johnsongrass by one and two weeks, respectively. Germination of tall morningglory, Florida beggarweed, ivyleaf morningglory, sicklepod and prickly sida was faster than Brazil pusley, strangler vine and beggarticks. Water stress of -0.2 MPa reduced the germination of ivyleaf morningglory and prickly sida, whereas tall morningglory, Florida beggarweed and sicklepod required -0.4 MPa osmotic potential to significantly reduce germination. Increasing the temperature from 15 to 20 and 30OC increased germination of weed species from 11 to 22 and 34%, respectively. Increasing water stress from -0.1 to -05 and -1.0 MPa resulted in 37, 6 and 0.3% germination compared to 47% with no water stress. Increasing temperature from 15 to 20 and 30OC resulted in 18, 36 and 56% germination at -0.1 MPa osmotic potential. Lower temperature and water stress was more inhibitory than high temperature and increased water stress to many weeds species. Decreased osmotic potential of -1.0 MPa resulted in complete germination inhibition of all species, except Florida beggarweed (11%). An increase in temperature of 5 or 10OC increased germination of tall morningglory from 10 to 34 and 43% at -0.5 MPa osmotic potential. At -0.5 MPa, Florida beggarweed had no germination at 15 or 20OC compared to 43% at 30OC, which was similar to 20OC and lower water stress (-0.1 MPa).

Abstract:

A field experiment was conducted at CCS Haryana Agricultural University Regional Research Station, Karnal during rabi 2007-08 and 2008-09 to evaluate the efficacy of sulfosulfuron tank mixed with carfentrazoneethyl against weeds in wheat. The treatments included tank-mix or sequential application of sulfosulfuron 25 g/ha with carfentrazone 20, 15 and 10 g/ha, alone application of sulfosulfuron 25 g/ha and carfentrazone 20 g/ha, sequential application of clodinafop 60 g/ha or sulfosulfuron 25 g/ha with metsulfuron 4 g/ha, sulfosulfuron+metsulfuron (ready-mix) 32 g/ha, pinoxaden 50 g/ha fb carfentrazone 20 g/ha, mesosulfuron+iodosulfuron (ready-mix) 14.4 g/ha, along with weed free and weedy checks. Tank mix or sequential application of sulfosulfuron with carfentrazone being at par reduced the density and dry weight of Phalaris minor similar to sulfosulfuron alone, mesosulfuorn+iodosulfuron, sulfosulfuron+metsulfuron (ready-mix) and sulfosulfuron fb metsulfuron during both the years and it was as good as weed free check during 2008-09. All the tank-mix and sequential applications of sulfosulfuron with carfentrazone were at par with carfentrazone alone and similar to weed free check in respect of density and dry weight of broadleaf weeds. Tank-mix and sequential application of sulfosulfuron with carfentrazone were at par with sulfosulfuron alone, all other check herbicidal treatments (except carfentrazone alone being inferior) and weed free check in respect of effective tillers and grain yield of wheat. There was no phytotoxicity of combination treatments of sulfosulfuron with carfentrazone except some brown freckles appearing on the leaves due to tank-mix treatments or carfentrazone alone, which disappeared within two weeks without any adverse effect on the crop. Hence, carfentrazone was found compatible with sulfosulfuron as tank mixture against complex weed flora in wheat with no loss of herbicidal efficacy.

Abstract:

The studies were conducted to determine the effect of straw retention and burning on Phalaris minor control. Reduced herbicide (isoproturon and pendimethalin) efficacy and increased P. minor infestation were observed with rice straw burning. A survey conducted in rice-wheat system revealed that majority of the farmers (65%) were burning rice straw in north-western Indian plains. For sustainability of rice-wheat system, instead of burning, residue should be either retained on surface or incorporated. The surface retention of rice residue of 5.0 and 7.5 t/ha reduced the weed dry weight in wheat by 23.4-30.3 and 35.5-44.1%, respectively. However, the yield and weed control were lower in various residue retention treatments without herbicides as compared to the herbicide application (sulfosulfuron 25 g/ha+metsulfuron 3 g/ha). Considering advantage of residue retention, efficient weed management options need to be evolved under such residue management practices

Abstract:

The compatibility of fenoxaprop-P-ethyl with carfentrazone-ethyl for the control of complex weed flora in wheat was evaluated during rabi 2005-06 and 2006-07 at CCS Haryana Agricultural University Regional Research Station, Karnal, India. The treatments included fenopxaprop + carfentrazone 100 and 120 g/ha in 4 : 1, 5 : 1 and 6 : 1 ratio, fenoxaprop+metsulfuron-methyl 100 g/ha in 30 : 1 and 40 : 1 ratio, fenoxaprop+2, 4-D Ester and Na salt 500 g/ha in 1 : 4 ratio, in comparison to fenoxaprop+A (adjuvant) 100 g/ha, fenoxaprop 120 g/ha and carfentrazone 20 g/ha along with weed free and weedy check. The density and dry weight of Phalaris minor decreased with widening of the ratio from 4 : 1 to 6 : 1 combination of fenoxaprop+carfentrazone at both the doses. In general, fenoxaprop+carfentrazone 120 g/ha was better than 100 g/ha in respect of density and dry weight of P. minor. Fenoxaprop+carfentrazone at 120 g/ha in all the ratios resulted in grain yield at par with weed free check during both the years. Among all the treatments, maximum number of effective tillers and grain yield were recorded with fenoxaprop+carfentrazone 120 g/ha (5 : 1) during both the years. Carfentrazone was compatible with fenoxaprop as tank mixture and there was no adverse effect on efficacy of both the herbicides. Fenoxaprop+carfentrazone 120 g/ ha (5 : 1) appeared to be the best combination for achieving maximum weed control efficacy and improved grain yield. Metsulfuron 2, 4-D Ester and Na salt had antagonistic effect on the efficacy of fenoxaprop when applied as tank mixture with it.

Abstract:

An experiment was conducted at experimental farm of Department of Agronomy, Punjab Agricultural University, Ludhiana (India) during rabi seasons of 2004-05 and 2005-06 in a split plot design comprising five planting techniques in main plots (conventional tillage, zero till sowing without stubbles, zero till sowing in standing stubbles, zero till sowing after partial burning and bed planting) and five weed control treatments in sub-plots (clodinafop 60 g/ha, clodinafop 60 g/hafb 2, 4-D 0.5 kg/ha, sulfosulfuron 25 g/ha, mesosulfuron+iodosulfuron 12 g/ha and unweeded control). Reduced dry matter of Phalaris minor Retz. and broadleaf weeds and higher wheat grain yield were recorded with zero till sowing in standing stubbles followed by zero till sowing after partial burning and bed planting. Clodinafop 60 g/ha alone controlled P. minor but did not control broadleaf weeds. Significantly reduced population of P. minor as well as broadleaf weeds and increased grain yield of wheat were observed with postemergence application of clodinafop 60 g/ha fb 2, 4-D 0.5 kg/ha, sulfosulfuron 25 g/ha and mesosulfuron+iodosulfuron 12 g/ha than clodinafop 60 g/ha alone and control. Among the planting techniques, zero till sowing in standing stubbles and among the weeds control practices sulfosulfuron 25 g/ha recorded highest wheat yield

Abstract:

In a field experiment, all weeds including Trianthema portulacastrum L. (T. portulacastrum) and 200 plants/m2 of T. portulacastrum resulted in significantly higher weed/T. portulacastrum dry weight, growth rate and relative growth rate than those in other treatments except all weeds excluding T. portulacastrum. These treatments caused significant reduction in soybean dry weight, crop growth rate, relative growth rate, leaf area index, net assimilation rate and uptake of N, P and K by soybean. All weeds excluding T. portulacastrum were comparable with them on the reduction of most of these parameters. Competition by all weeds including T. portulacastrum resulted in significantly lower values of pods/plant, seeds/pod, seeds/plant and seed weight/plant of soybean than other treatments except 200 T. portulacastrum/m2. All the densities i. e. 25, 50, 75, 100 and 200 T. portulacastrum/ m2 and all weeds including and excluding T. portulacastrum resulted in significantly lower seed yield than weed-free check, but the reductions were greater in all weeds including T. portulacastrum and 200 T. portulacastrum/m2. There was significant negative correlation (at P≤ 0.01) between the T. portulacastrum density and soybean seed yield.

Abstract:

A field experiment was conducted at Udaipur during 2002-03 and 2003-04 with 11 weed and three nutrient management practices to study the effect on growth, yield and quality of coriander (Coriandrum sativum). Weed management practices significantly reduced weed density, dry matter and nutrient uptake by weeds and improved growth (plant height), yield attributes (umbels/plant and weight of seeds/umbel), seed and biological yield, quality parameters (essential oil content and oil out turn) and nutrient uptake by crop as compared to control. Two hand weedings (HW) at 30 and 45 DAS resulted in maximum reduction in weed density, dry weight and nutrient depletion by weeds and gave the highest seed (1.59 t/ha) and biological yield (4.11 t/ha) of coriander. However, maximum essential oil content, oil out turn and B : C ratio (2.13) were obtained by pendimethalin 1.0 kg/ha+one hand weeding at 45 DAS. Both the treatments remained at par in reduction of weed dry matter and nutrient uptake by weeds and resulted in maximum weed control efficiency (88.50%) as compared to rest of the practices. Balanced fertilization with 60 kg N+30 kg P+30 kg K+30 kg S/ha also significantly improved weed dry weight and nutrient uptake by weeds, but simultaneously enhanced crop nutrient uptake, plant height, umbels/plant, 1000 seed weight, seed and biological yield, essential oil content, oil out turn and B : C ratio over N+P and N+P+K application. Treatment of pendimethalin 1.0 kg/ha+one hand weeding at 45 DAS resulted in the highest seed yield, maximum weed control efficiency (88.50%) and B : C ratio (2.13). However, minimum nutrient uptake by crop and maximum nutrient removal by weeds were noted under weedy check.

Abstract:

A field experiment was carried out during 2005 and 2006 at Belvatagi, Karnataka to work out the weed management practices in drill sown onion+chilli+cotton relay intercropping in rainfed Vertisols. Pre-emergence application of oxyfluorfen @ 0.15 kg/ha and pendimethalin @ 1.0 kg/ha reduced the weed growth significantly but oxyfluorfen was toxic to onion and chilli. Pendimethalin @ 1.0 kg/ha with two or more hand weedings resulted in higher onion bulb yield and at par with farmers’ practice (88.37 q/ha). Chilli fruit yield was significantly higher with oxadiargyl @ 0.09 kg/ha with hand weeding at 20, 40, 60 and 80 DAS (11.8 q/ha), which was at par with weed free check (12.99 q/ha) and farmers’ practice (10.09 q/ha). Seed cotton yield was found better with oxyfluorfen @ 0.15 kg/ha alongwith hand weeding at 20, 40 and 60 DAS. Application of pendimethalin @ 1.0 kg/ha with three hand weedings at 20, 40 and 60 DAS was found better for onion bulb and chilli fruit yield and comparable with farmers’ practice for the onion+chilli+cotton relay intercropping system. This resulted in higher net returns (Rs. 64,390/ha) and B : C ratio (3.99).

Abstract:

Greenhouse studies were conducted to examine the effect of non-ionic ‘Induce’ and the organosilicone ‘Silwet L-77’ adjuvants on the rainfastness of glyphosate applied to a broadleaf weed-wild mustard. Glyphosate was tank mixed with and without adjuvant at three different concentrations. No rainfall and six simulated rainfall treatments at 30 min, 1, 2, 4, 6 and 24 h after glyphosate treatment were applied to the treated plants. With the addition of either adjuvant, absorption of 14C glyphosate was enhanced, which presumably led to increased rainfastness as indicated by good control of wild mustard plants even when simulated rainfall occurred 30 min after application. Addition of both adjuvants also improved translocation of 14C glyphosate. Simulated rainfall immediately after glyphosate application washed off chemical from the foliage, leaving not enough chemical to have phytotoxic effects. Simulated rainfall that occurred 30 min after application did not affect the efficacy of glyphosate as a significant amount of 14C glyphosate had already been absorbed. Use of the organosilicone adjuvant achieved higher per cent control of weeds than the nonionic adjuvant, presumably through increased rainfastness of glyphosate. Addition of non-ionic adjuvant ‘Induce’ at 0.25% in and organosilicone ‘Silwet L-77’ at 0.1% was better in achieving effective control of wild mustard than other rates of adjuvants with glyphosate under different simulated rainfalls. Thus, addition of an adjuvant helped in absorption and translocation of 14C glyphosate as quickly as 30 min after treatment.

Abstract:

Efficiency of Eisenia foetida, Amyanthes diffringens and Eudrillus eugineae in vermicomposting of plant biomass viz., rice straw, Ipomoea carnea, Eichhornia crassipes alone and in mixture was studied during summer and winter seasons. All the species were found efficient in vermicomposting of plant biomass. Time required for composting varied from 50-70 days and 55-75 days during summer and winter seasons, respectively. E. foetida was at par with E. eugineae as regards to their multiplication rate and composting period. The multiplication rate was lowest with A. diffringens which also took relatively longer time for composting. The compost recovery did not change with earthworm species. The highest compost recovery was obtained from Ipomoea biomass followed by mixture of rice straw, Ipomoea and Eichhornia biomass. The compost recovery was lowest with Eichhornia biomass. Irrespective of earthworm species, the population at maturity of the compost was increased by 8-12 times over the initial population. Earthworm activity substantially narrowed down the C : N ratio and increased the nutrient content in the compost over the initial value of the respective biomass. Different earthworm species could not show any significant variation in the nutrient content except for nitrogen and phosphorus, which were significantly higher with E. foetida and E. engineae compared to A. diffringens. Vermicompost prepared from Ipomoea biomass had the highest nutrient level followed by mixture use of rice straw, Ipomoea carnea and Eichhornia crassipes biomass. The lowest C : N ratio was recorded in the vermicompost from Ipomoea biomass, while the highest was recorded from rice straw.
