Effect of methods of nursery raising and nitrogen levels on grain yield of hybrid rice.

摘要

In a field experiment during kharif 1993 and 1994 at Kaul, Haryana, India, rice cv. ORI 161 which had been dry sown or puddled in the nursery and PMS2A/IR31802 which had been dry sown only were given 0, 50, 100, 150 or 200 kg N/ha after transplanting. Grain yield and yield component values increased with increasing N rate. ORI 161 gave higher yields than PMS2A/IR31802, irrespective of method of nursery raising.
