Abstract

Maize is third most important cereal crop in Pakistan after wheat and rice. Experiment was conducted at Agricultural Research Institute Tarnab, Peshawar during Kharif 2007 to study the different weed control technique in maize. The treatments were wheat straw, saw dust, polyethylene (white), polyethylene (black), newspaper, Primextra Gold 720SC, hand weeding and weedy check. The effect of all these treatments were studied on weed density (m- 2), fresh weed biomass (g m-2), leaf area (cm2) and cob length (cm). Primextra Gold 720SC and polyethylene (black) giving only (6.5) and (20.0) weeds respectively, as compared to (110.8) weeds m-2 in weedy check plots. Maximum leaf area of 561.23 and Primextra Gold 720SC and polyethylene (black) treated plots respectively. The minimum (464.34 cm2) leaf area was recorded in weedy check plots.
