Abstract
Field experiments were conducted during 2006 and 2007 in Peshawar, using open pollinated maize variety “Azam” in RCB design with split-split plot arrangements having three factors viz., tillage, maize populations and mulches. The tillage levels (zero and conventional) were assigned to main plots, populations (90000, 60000 and 30000 plants ha-1) to sub-plots and the mulches (weeds mulch, black plastic mulch, white plastic mulch and mungbean as living mulch), a hand weeding and a weedy check were allotted to sub-sub plots. Data were recorded on fresh weed biomass (kg ha-1), grains cob-1
