Abstract:
An experiment was laid out to study the “Comparative evaluation of happy seeder technology with other sowing methods and weed management practices in linseed under rice - based cropping system in conservation agriculture” during kharif and rabi season of (2019-20 and 2020-21) at IGKV, Raipur, Chhattisgarh. The experiment was conducted in split plot design with three replications comprising three methods of sowing viz., T₁: zero seed drill, T₂: happy seed drill and T₃: normal seed drill (soil preparation only by rotavator) in main plot and three weed management practices viz., W₁: chemical weed control, W₂: hand weeding twice and W3: unweeded check control in sub plot respectively. The results reveled that, among the methods of sowing all the growth parameters i.e. plant height, number of branches plant^-1, dry matter accumulation, yield attributes viz., number of capsules plant-1, number of seeds capsule-1and 1000seed weight (g) were significantly higher under T₂- happy seed drill followed by T₃-normal seed drill (soil preparation only by rotavator). The pooled data of seed and stover yield of linseed were also found maximum (1492 and 2991 kg ha^-1, respectively) when shown with happy seed drill, which was significantly higher in comparison to the sowing with normal seed drill (soil preparation only by rotavator) and zero seed drill.
