An experiment was conducted during two consecutive rainy seasons at Rajendra Agricultural University, Pusa to study the effect of establishment method, fertility levels and weed management practices on scented hybrid rice. Two crop establishment methods (standard method of transplanting and SRI method of transplanting), three fertilizer levels (80:40:20, 100:60:40, 120:80:60 N, P2O5, K2O kg/ ha) and three weed management practices (weedy check, one hand weeding (HW) at 35 days after transplanting (DAT) and pre-emergence application of pendimethaline at 1 kg/ha were tested in a randomized block design. SRI method of transplanting recorded higher grain yield than the standard method of transplanting. The yield increased with the increase in fertility levels and was maximum with 120:80:60 kg/ha N, P2O5 and K2O/ha. One hand weeding registered higher grain and straw yields. Weed control efficiency was better with one hand weeding at 35 DAT in comparison to pre–emergence application of pendimethalin at 1 kg/ha.
