Response of weed and tillage management practices under growth & yield attributes and yield in pearl millet (Pennisetum glaucum) - mustard (Brassica juncea) cropping system

Abstract

The present investigation entitled “Weed and tillage management practices on growth and yield of pearl millet (Pennisetum glaucum) - mustard (Brassica juncea) cropping system” was conducted during kharif & rabi seasons of 2015-16 & 2016-17 at Research Farm, RVSKVV, College of Agriculture; Gwalior (M.P.). The experiment consisted of 15 treatment combinations comprising 5 tillage practices viz. Conventional tillage (kharif & rabi), Conventional tillage (kharif) & Zero tillage (rabi), Zero tillage (kharif & rabi), Zero tillage (kharif) & Zero tillage + Crop residue (rabi) and Zero tillage + Crop residue (kharif & rabi) as horizontal plots and 3 weed management practices viz. RD of herbicide (Atrazin @0.5 kg ai/ha PE+2,[email protected] kg ai/ha EPoE) kharif & (IPU @0.75 kg ai/ha PE or Oxydairgly @0.25 kg ai/ha PE) rabi season, IWM ([email protected] kg ai/ha PE+1 HW at 25DAS) kharif & ([email protected] kg ai/ha +1 HW at 25 DAS) in rabi season and Weedy check (kharif and rabi season) as vertical plots laid out in strip plot design with three replications. All recommended practices were followed during crop growing season. The interaction of Conventional Tillage (kharif season) & Zero Tillage (rabi season) with IWM (Atrazin @ 0.5 kg ai/ha PE + 1 HW at 25 DAS) kharif & (Pendimethalin @ 1.0 kg ai/ha + 1 HW at 25 DAS) in rabi season registered significantly effective value of weed parameters, crop growth parameters, yield attributes and yield; while the minimum value was recorded under interaction of Zero Tillage (kharif and rabi season) with Weedy check (kharif and rabi season) over rest of the interactions.
