The treatments tested were two sowing dates (Mid November and end November) and six competition durations (No competition, competition for 4,6,8,10 weeks and full season competition). The experiment was laid out in a split plot arrangement with three replications placing the sowing dates and competition durations in the main and sub plots, respectively. Common weeds of wheat were allowed to compete with crop for different prescribed competition durations. The results revealed that various growth and yield components were significantly influenced by sowing dates and weed competition. Significantly maximum grain yield of 6122.21 kg haG 1 was obtained in no weed competition treatment followed by competition upto 4 to 6 weeks which were statistically at par with each other. However, the sowing dates had no significant effect on final grain yield.

Seeding times had a significant effect on different growth and yield parameters, where mid-October seeding produced maximum seed yield (1699.12 kg haG 1). However, the seed oil content were highest (43.44%) in case of early seeding (seeding on September, 26) and gradually decreased with delay in sowing. The different seeding rates and the interactions between seeding times and seed rates were found to be non significant for almost all the parameters except that of numberof seeds podG 1 where, 5 kg seed haG 1 produced maximum number of seeds podG 1 (19.85).
