Zero tillage had more grassy weeds, whereas conventional tillage had more of sedge and broad-leaved weeds. Zero tillage significantly reduced the weed density and total weed dry weight as compared to conventional tillage. Wheat cv. HUW 234 had more light interception, minimum weed density and total weeds dry weight accumulation than HP 1761, HUW 468, HP 1731 and NW 1012. The maximum grain and straw yields were obtained with HUW 234 under zero tillage and hand weeding.
