Abstract:
A field experiment was conducted during 2018-19 and 2019- 20 at Agriculture Farm, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal to study the effect of tillage and weed management practices on weed growth and productivity of yellow sarson in direct seeded rice - yellow sarson - greengram cropping system under conventional and conservation tillage practices. The experiment comprising of four horizontal tillage strips and three vertical weed management strips was laid out in a strip plot design with three replications. Results revealed that conservational tillage (Zero tillage +residue) along with recommended herbicide (RH) (Pendimethalin at 0.75 kg ha^-1) + one hand weeding (HW) recorded the lower values of total weed density and dry weight at 60 DAS in both the years. Conservational tillage (Zero tillage +residue) along with recommended herbicide (RH) (Pendimethalin at 0.75 kg ha^-1) + one hand weeding (HW) also registered higher value of seed yield of yellow sarson over other treatments during both the years.
