Abstract:

An experiment was conducted at Agricultural Research Farm, NWFP Agricultural University Peshawar during Rabi 2006-07 to study the effect of seeding rate and row spacing of wheat on weeds and grain yield. The experiment was laid out in Randomized Complete Block design with split plot arrangement, having three replications. Wheat seed rates (100, 120 and 140 kg ha-1) were assigned to main plots while row spacing 20, 24, 30 and 40 cm were assigned to sub plots. Results indicated that closer row spacings were more effective in decreasing the weed density while higher seeding rates did not affect the weed density. It is concluded from the data obtained that weeds and yield related parameters of wheat were affected by seed rates as well as by row spacings. Findings also suggested that higher seed rate (140 kg ha-1) of wheat and closer row spacing (24 cm) can be used effectively to suppress the weeds. This cultural control method should be incorporated in integrated weed management packages.
