Yield Performance of Mungbean Genotypes as Influenced by Herbicides with Different Weed Management Practices

This research was conducted to investigate the effect of different herbicides with weed management practices on growth and yield performance of mungbean genotypes. The experiment consisted of two factors were mungbean genotypes and weed management. There were two genotypes namely BARI Mung 6 and BARI Mung 8. While there were five weed management practices namely control/no weeding and without herbicide application (T1), hand weeding at 20 and 40 DAS (T2), pre emergence herbicide (Panida) at 1-2 DAS (T3), pre emergence herbicide (Neon) at 2-3 DAS (T4), and post emergence herbicide (Neon) at 10-15 DAS+hand weeding (T5). The results revealed that BARI Mung 6 stand superior to BARI Mung 8 in respect of dry matter content/plant, pods/plant, seeds/plant, seed yield, and 1000 seed weight. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47), maximum weed control efficiency (33.78 %) obtained from T3 treatment. Based on the interaction effect showed that BARI Mung 6 weeded with pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes showed 2.29 % higher seed yield.

A field experiment was conducted during rabi seasons of 2007-08 and 2008-09 on mollisols at G.B. Pant University of Agriculture & Technology, Pantnagar to study the performance of fieldpea (Pisum sativum L.var arvense) under different planting methods, irrigation levels and weed management practices. Results revealed that growth attributes as plant height, number of branches and dry matter accumulation per plant, number and dry weight of nodules per plant, density and dry matter of weeds/unit area, nutrient uptake and yield attributes as pods/plant, 1000-grain weight, grain yield/plant and grain yield of fieldpea were significantly higher under raised bed planting as compared to flat bed. Planting on raised bed increased grain yield of fieldpea by 17.5% over flat bed. Two irrigations applied at critical stages i.e. pre-flowering and pod formation proved promising in increasing the growth, nutrient uptake, yield attributes and grain yield of pea. One hand weeding done at 25 days after sowing (DAS) reduced the density and dry matter of weeds significantly and one hand weeding done at 25 DAS increased the values of growth attributes, number and dry weight of nodules, nutrient uptake, yield attributes and grain yield as compared to pendimethalin 1.0 kg a.i./ha applied as pre-emergence and weedy check.

To study the weed management in drilled paddy an experiment was conducted at Agriculture Research Station, Anand Agricultural University, Derol Dist: panchmahal, Gujarat during kharif seasons of the years 2012-13, 2013-14 ,2014-15 and 2015 -16 . Ten treatments for weed management were studied in randomized block design with four replications. Results that all the growth and yield attributes except plant height and test weight were significantly influenced due to different weed control treatments. The grain and straw yield of drilled paddy were also altered significant due to weed control treatments. In general, T2 (two hand weeding at 20 and 40 DAS) recorded the highest yield among all. It was, however, at par with three other treatments which included pre and post emergence application of herbicides. Since, the application of Oxadiargyl @ 90 g/ha f/b Bisbyribac sodium @ 25 g/ha at 20 DAS is one among the dual application of herbicide, it can be recommended for drilled paddy in options of two hand weeding.

Weeds are serious problem in dry direct seeded rice (DDSR). A field experiment was conducted during rainy seasons of 2010 and 2011 at research farm of the Regional Agricultural Research Station (RARS) Parwanipur, to study the effect of integrated weed management practices on the performance of dry direct seeded rice. Ten treatment combinations viz; weedy, weed free (weekly), Pendimethalin fb (followed by) Bispyribac, Pendimethalin fb two hand weeding, Stale seedbed fb Bispyribac, Stale seedbed fb Pendimethalin fb Bispyribac, Mulch 4 t/ha fb Bispyribac fb one hand weeding, Stale seedbed fb mulch 4 t/ha fb Bispyribac, Pendimethalin and Sesbania co-culture fb 2,4-D Na salt fb one hand weeding and Pendimethalin fb 2,4-D fb one hand weeding were tested in a randomized complete block design and replicated thrice. Observations were taken on weed, plant growth and yield attributes, yield, and socio-economic parameters. All weed control treatments significantly reduced the weed density and dry weight of weed resulting significant increase in yield of DSR over weedy check in both years. Weed free treatment resulted the highest yield, however, it was not economical due to high cost of cultivation. The use of Pendimethalin fb 2,4-D fb one hand weeding produced yield (5161 in 2010 and 6160 kg/ha in 2011) which were statistically at par with yield (5305 in 2010 and 6319 kg/ha in 2011) obtained under the weed free treatment. Further, the highest benefit cost ratio (CBR) 1.77 and 2.22 and net return Rs 47700 and 75084/ha during 2010 and 2011, respectively, were obtained under this treatment indicating its superiority over other treatments. The grain yield, yield attributing characters viz. panicles per m2, panicle weight, filled grain per panicle, thousand grain weight as influenced by different weed management practices revealed that higher yield resulted from weed free plot followed by Pendimethalin followed by two hand weeding and Pendimethalin followed by 2,4-D followed by one hand weeding. However, the net return per unit investment resulted highest in Pendimethalin followed by 2,4-D followed by one hand weeding. This proved that amid increasing wage rate and labor scarcity integrated weed management through Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha as pre- emergence herbicide application followed by 2,4-D sodium salt 80 WP @ 0.5 kg a.i./ha followed by one hand weeding or stale seed bed followed by Pendimethalin 30 EC (stomp) @ 1 kg a. i./ha followed by Bispyribac (nominee gold) @ 25 g a. i./ha 10 % @ 200 ml/ha at 20 days of seeding resulted best alternative for manual hand weeding practices giving higher net return per unit investment.

Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

A field experiment was conducted during Kharif seasons of 2014 and 2015 at Udaipur (Rajasthan) to find out the effect of weed management on productivity of clusterbean under varying fertility levels. The results revealed that among various weed management practices, two hand weeding 20 and 40 DAS recorded significantly lower weed dry matter, higher weed control efficiency, higher values of yield attributes, seed, haulm and biological yield during both the years over rest of the treatments except sequential application of pendimethalin fb imazethapyr which was statistically at par. Further, application of Imazethapyr fb hand weeding and pendimethalin fb hand weeding also gave comaparable results with pendimethalin fb imazethapyr in terms of weed control efficiency and yields. Among the fertility levels application 20 Kg N + 40 Kg P2O5 ha-1 significantly increased pods plant-1 (24.04), seeds pod-1, (7.12), test weight ( 25.33 g), seed ( 1035 kg ha-1), haulm (2161 kg ha-1) and biological (3196 kg ha-1 ) yield and harvest index ( 31.98 %) of clusterbean over 10 Kg N + 20 Kg P2O5 ha-1 however, it was found statistically at par with fertility level 30 Kg N + 60 Kg P2O5 ha-1. Therefore, clusterbean should be fertilized with 20 Kg N + 40 Kg P2O5 ha-1 and weeds must be controlled with pendimethalin (PE) fb imazethapyr 0.1 kg ha-1 20 DAS .

A field experiment was conducted during kharif seasons of 2009 & 2010 at Model Organic Farm of Department of Organic agriculture, CSK Himachal Pradesh Krishi Vishvavidyalya Palampur in factorial randomized block design with three replications consisting of eight treatment combinations. The treatments included two methods of weeding (mechanical weeding with cono weeder & hand weeding) and 4 spacings (25x25, 30x30, 20x20 and 30x20 cm). Rice variety RP-2421 was transplanted in second week of July during both the years following all organic packages of practices. The weeding was done at 20 & 40 days after transplanting rice. The dominant species of weeds were Echinochloa crusgalli, Digitaria sanguinalis and Panicum dichotomiflorum among grasses; Cyperus iria and Cyperus difforimis among sedges and Aeschynomera indica, Ammania spp and Commelina benghalensis among broadleaved weeds.The experimental results revealed that 2 mechanical weedings with cono-weeder at 20 & 40 DAT resulted in significantly higher values of yield attributes viz. effective tillers/m2 & panicle length and hence higher paddy yield and lower weed dry weight over hand weeding twice (20 & 40 DAT). However, grains/ panicle and 1000 grain weight did not vary significantly during both the years. Among spacings 30x30 cm being at par with 25x25 cm & 30x20 cm recorded significantly higher paddy yield and lower weed dry weight over 20x20 cm during both the years. The interactions between method of weedings& spacing were observed to be non-significant during both the years of study.

An experiment was conducted during September 2019 - January 2020 to investigate the effects of cultivars and different weed management practices on yield attributes, yield, nutrient uptake and soil micro-flora in dry direct-seeded rice (DDSR). Experiment was laid out in split plot design replicated thrice. The treatment combination consisted of three levels of cultivars in main plot (ADT 46, CO 52 and Improved white ponni) and five levels of weed management practices in the sub plots (application of pendimethalin @ 1 kg a.i ha-1 as pre-emergence herbicide at 3 days after sowing (DAS), bispyribac-sodium @ 0.02 kg a.i ha-1 as post-emergence herbicide at 20 DAS, sequential application of pendimethalin @ 1 kg a.i ha-1 followed by (fb) bispyribac-sodium @ 0.02 kg a.i ha-1, hand weeding twice at 20 and 40 DAS and weedy check). Both the cultivars and weed management practices influenced the growth, nutrient uptake, soil microbial population and yield of the DDSR. However, the interaction did not influence any of the parameters significantly. Rice cultivar ADT 46 proved to be superior with respect to nutrient uptake and yield. Whereas, among weed management practices, the highest nutrient uptake and yield were obtained with sequential application of pendimethalin @ 1 kg a.i ha-1 fb bispyribac-sodium @ 0.02 kg a.i ha-1.
