Tillage and weed management effect on productivity of maize in maize-wheat cropping system

A field experiment was carried out at Sher-e-Kashmir University of Agriculture Science and Technology of Jammu during kharif season of 2013 and 2014 to investigate the effect of tillage and weed management practices on productivity of maize under maize-wheat cropping system in sub-tropical irrigated conditions of Jammu. Among the tillage treatments, Conventional tillage (CT) preceded by Conventional tillage (CT) resulted in higher Plant height, dry matter, leaf area index, number of grains per cob, 1000-grains weight, grain yield, stover yield and significantly lowered the density and dry matter of weeds which was at par with Conventional tillage (CT) preceded by Zero tillage (ZT). Among various weed management treatments, two hand weeding recorded higher Plant height, dry matter, leaf area index, number of grains per cob, 1000-grains weight, grain yield, stover yield and significantly lowered the density and dry matter of weeds which was at par with Atrazine 1.0 kg/ha.
