A trial was conducted in red soils at the Research farm of AICRP on Groundnut, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, to study the effect of different weed control treatments on groundnut yield during two consecutive Rabi (winter) seasons of 2018-19 to 2019-20. Amongst the different herbicides, ready mix application of pendimethalin + imazethapyr along with manual weeding efficiently controlled weed density and weed dry matter of all types of weeds. It also incurred significantly higher yield attribute and yield of groundnut over all the other herbicidal treatments, viz . branch/plant (5 and 4.8), number of pods/plant (19.3 and 17.2), pod yield (2.63 and 2.35 t/ha) and haulm yield (4.10 and 3.93 t/ha), net returns of 82370 and 66740/ha and B: C (2.7 and 2.3) in 2018-19 and 2019-20, respectively.. The lowest weed dry matter, weed density and weed index and WCE were recorded with this treatment at different stages of the crop growth period. The results obtained from the trial suggested that ready mix application of pendimethalin + imazethapyr along with manual weeding was the best measure to control all types of weeds effectively along with the highest pod yield.

A field experiment was conducted on sandy loam soils to identify alternate weed management treatments to economically manage weeds and improve mustard growth and yield of mustard. Among tested weed management treatments, higher growth parameters, higher yield attributes (number of siliquae / plants and seeds / siliquae) and yield of mustard were observed under inter-cultivation and hand weeding twice at 15 and 30 days after seeding (DAS) which was at par with pre-emergence application (PE) of oxadiargyl 0.09 kg / ha fb inter-cultivation at 30 DAS.

The understanding of the diverse weed flora composition and weed shift in conservation agriculture production system is important to identify weed management component to increase agro-ecosystem sustainability. Hence, in this study, different tillage and weed management practices were assessed to evaluate their impact on diverse weed flora composition and shift in maize-wheat cropping system in North Western Himalaya from 2018-20 in an ongoing long-term experiment being conducted since 2013. Fifteen treatment combinations comprising of five tillage treatments, viz . conventional tillage (CT) in maize-CT in wheat; CT-zero tillage (ZT); ZT-ZT; ZT-zero tillage in combination with residue retention (ZTR) and ZTR-ZTR and three weed management treatments, viz . recommended herbicide (H) in maize-recommended herbicide (H) in wheat; integrated weed management (IWM)-IWM and hand weeding (HW)-HW were evaluated in a strip plot design. In CT, annual weed species were dominant, whereas, perennial weeds dominated in zero tillage (ZT). A shift in weed species with greater dominance of monocots and a marginal decrease in dicots was observed. Parthenium hysterophorus , an obnoxious weed, was observed in the experimental field in maize only during 2018. The monocot weed ( Echinochloa colona ) had higher relative density (RD), relative abundance (RA), relative frequency (RF) and important value index (IVI) compared to the dicot weeds in maize crop. In Rabi (winter) season, Avena ludoviciana (monocot grass) had higher RD, RF and IVI values, while, Daucus carota (perennial weed) had higher RA when compared to the other annual and biennial weeds. The grain yield of main and intercrop and system productivity were higher in conservation agriculture-based production systems in combination with recommended herbicide (ZTR+H-ZTR+H) in maize-wheat based cropping systems.

A field experiment was conducted during rainy (Kharif) season of 2019 at N.E.B. Crop Research Centre of GBPUA&T, Pantnagar with an objective to identify the best establishment method and weed management treatment for maize to attain higher maize growth, yield and economic returns. The experiment was conducted in split-plot design with three replications comprising of three establishment methods as main plot factor and seven weed management treatments as sub-plot factor, replicated thrice. Among the establishment methods, raised bed system was found most effective in reducing weed growth. The highest weed control efficiency of 85.7% was recorded with pre-emergence application (PE) of atrazine 1000 g/ha fb post-emergence application (PoE) of tembotrione 120 g/ha which was followed by rice straw mulch 5 t/ha fb tembotrione 120 g/ha PoE and tembotrione 120 g/ha PoE alone. Raised bed system resulted in 8.0% higher maize grain yield over zero till system and highest net return and B:C ratio. Among the weed management treatments, highest maize grain yield, net return and B:C ratio were recorded with atrazine 1000 g/ha PE fb tembotrione 120 g/ha PoE.
