Abstract: A field experiment was conducted during the rabi season of 2021-22 at Agricultural Research Farm, School of Agricultural Sciences and Technology, RIMT University, Mandi Gobindgarh, Punjab to study the effect of sowing time and seed rates on grain yield of oats (Avena sativa L.). The experiment was laid out in a randomized complete block design (RCBD) and replicated thrice. The treatments comprised of three sowing dates (5th November, 25th November and 15th December) and three seed rate (50,62.5 and 75 kg/ha). The variety OL-14 was used during the experiment. The crop sown on 25th November recorded the highest plant height (149.82 cm), more effective tillers per meter row length (133.70), panicle length (37.90 cm), grains per panicle (81.30), grain weight per panicle (2.90 g) which was significantly higher over 5th November but at par with 15th December sown crop. The highest grain yield was observed in crop sown on 25th November (24.20 q/ha) which was significantly higher over 5th November (21.66 q/ha)sown crop but at par with 15th December (23.02 q/ha) sown crop. The crop sown with seed rate of 75 kg/ha produce more plant height (150.07 cm) which is significantly higher over 50 kg/ha seed rate (142.18 cm)but at par with 62.5 kg/ha (145.39cm) sown crop. Whereas 62.5 kg/ha produce significantly higher grain yield (25.22q/ha) over 50 kg/ha (20.18 q/ha) but at par with 75 kg/ha (23.47q/ha). Interaction effect between sowing dates and seed rateswas found to be non-significant in all the parameters.
