A field experiment was undertaken at PAU, Regional Station (Bathinda) to evaluate the effect of weed management practices on the performance of cluster bean [(Cyamopsis tetragonoloba (L.) Taub] under AICRP on Arid Legumes during the kharif season of 2015 and 2016. Data revealed that weed dry matter was lowest in case of weed free check (T8) as plots were kept weed free as per the treatment. Among other treatment combinations Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2-3 leaf stage of weeds (T7) produced the lowest weed dry matter closely followed by Pendimethalin @ 0.75 kg a.i./ha as PE+ One Intercultivation at 20-25 DAS (T6) and Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr @ 40g a.i./ha at 2-3 leaf stage of weeds (T5). WCE was highest in weed free followed by Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2-3 leaf stage of weeds (T7). Highest seed yield was recorded in weed free check followed by Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr @ 40g a.i./ha at 2-3 leaf stage of weeds (T5), Pendimethalin @ 0.75 kg a.i./ha + One Intercultivation at 20-25DAS (T6) and Pendimethalin @ 0.75 kg a.i./ha as PE + Imazethapyr+ Imazamox @ 40g a.i./ha at 2-3 leaf stage of weeds (T7).

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.

Kharif Season

A field experiment was conducted during the rainy (kharif) season of 2013 and 2014 to find out the effect of “influence of mulching practices, varieties and fertility levels on growth and productivity of clusterbean ,,.The results revealed that the plastic mulch significantly increased the growth and yield characterstics, seed yield as well as economics over the weed biomass mulch and no mulch. Variety HG-563 recorded significantly higher growth characterstics, yield attributing, seed yield and economics as compared to RGC-1055. Among the fertility levels, application of 75% RDF + VC 5 t/ha resulted in significantly higher growth characterstics, yield attributing, seed yield and economics over all the remaining fertility levels. Thus, it can be concluded that in clusterbean (variety HG-563), adoption of plastic mulch along with RDF 75%+ 5 t/ha vermicompost is recommended for erratic and scarce rainfall as well as low sustainability of soil.

Weed Removal

Herbicide-resistant canola dominates the canola market in Canada. A multiyear field experiment was conducted at three locations to investigate the effect of time of weed removal (two-, four-, or six-leaf canola) and herbicide rate (50 or 100% recommended) in three herbicide-resistant canola systems. Weeds were controlled in glufosinate-resistant canola (GLU) with glufosinate, in glyphosate-resistant canola (GLY) with glyphosate, and in imidazolinone-resistant canola (IMI) with a 50:50 mixture of imazamox and imazethapyr. Canola yields were similar among the three canola cultivar–herbicide systems. Yields were not influenced by 50 vs. 100% herbicide rates. Timing of weed removal had the greatest effect on canola yield, with weed removal at the four-leaf stage giving the highest yields in most cases. Percent dockage was often greater for GLU and IMI than for GLY. In comparison with the other treatments, dockage levels doubled for GLU after application at 50% herbicide rates. The consistency of monocot weed control was usually greater for GLY than for GLU or IMI systems. However, weed biomass data revealed no differences in dicot weed control consistency between IMI and GLY systems. Greater dockage and weed biomass variability after weed removal at the six-leaf stage or after low herbicide rates suggests higher weed seed production, which could constrain the adoption of integrated weed management practices in subsequent years.

Interference Study

Seeding rate and row spacing are management practices that affect flax seed yield. Two experiments were conducted from 1988 to 1990 to determine the influence of flax seeding rates (300, 600, and 900 seeds m−2) and row spacings (9, 18, and 27 cm). One was a flax-weed interference study (three sites) and the other was a weed-free study (13 sites). In the presence of weeds, increasing seeding rate from 300 to 900 seeds m−2 improved flax seed yield by 180 kg ha−1, and reduced broadleaf weed yields by 300 kg ha−1 and grassy weed yields by 180 kg ha−1. In weed-free conditions, seed yield was not affected by seeding rate. Row spacing did not affect flax yield and had minor effects on weed yields when weeds were not controlled. When weeds were controlled, seed yield in the 9-cm row spacing was 9% (15% in the flax-weed interference study) greater than in the two wider row spacings. Seeding rate and row spacing independently influenced flax yield, and their effect was consistent among sites with weeds present, but was not consistent when weeds were controlled. Our results showed that flax seeding rate was an important component of integrated weed management. Key words: Flax, seeding rate, row spacing, weed interference

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.
