Abstract:

A field experiment was conducted during the rabi season of 2017-18 at the Agricultural Farm of the Institute of Agriculture (PalliSikshaBhavana), Visva-Bharati, Sriniketan, West Bengal to study the effect of tillage and weed management practices on weed population dynamics and growth in wheat. The experiment was laid out in split-plot design with three replications. Two tillage practices comprising of Zero tillage (ZT) and Conventional tillage (CT) and eight weed management practices viz. Straw mulching alone at 4.0 t ha-1, Pendimethalin at 0.75 kg ha-1, Clodinafoppropargyl 15% + Metsulfuron methyl 1% WP at 0.40 kg ha-1, Pendimethalin at 0.75 kg ha-1 straw mulching at 4.0 t ha-1, Pendimethalin at 0.75 kg ha-1 fbclodinafoppropargyl 15% + metsulfuron methyl 1% WP at 0.40 kg at, Straw mulching alone at 4.0 t ha-1 fbclodinafoppropargyl 15% + metsulfuron methyl 1% WP at 0.40 kg , Weed free and Weedy check were assigned to the sub-plot. It was witnessed that ZT caused a substantial reduction in the population of narrow-leaved and broad-leaved compared to CT. Among the weed management practicespendimethalin at 0.75 kg ha-1 fb straw mulching at 4.0 t ha-1, pendimethalin at 0.75 kg ha-1 fb clodinafop-propargyl + metsulfuron methyl 0.4 kg ha-1 and sole application of pendimethalin at 0.75 kg ha-1 registered the lowest density as well as biomass of grassy weeds while straw mulching fb clodinafop-propargyl + MSM at 0.40 kg ha-1 and pendimethalin at 0.75 kg ha-1 fb clodinafop-propargyl + metsulfuron methyl 0.4 kg ha-1 recorded the lowest density as well as biomass broadleaved weeds. Lower values of weed density, total weed biomass and higher yield were registered with combination of zero tillage with integrated use of pre-emergence herbicide pendimethalin at 0.75 kg ha-1 with straw mulching at 4.0 t ha-1and pendimethalin at 0.75 kg ha-1 fbclodinafop-propargyl + metsulfuron methyl at 0.4 kg ha1.
