Effect of planting seedlings and nitrogens on yield of rice (Oryza sativa)

A field experiment was conducted during rainy season of 1986-1988 to study the individual and combined effects of number of planting seedlings;hili and different levels of N on yield of 'Subhadra' ('DR 92') rice (Oryza sativa L.). Planting 4 seedlings/hill significantly increased the plant height, length of panicle, grains/panicle and 1,000-seed weight than its higher and lower number of seedlings. The treatments also significantly increased the yield. Application of 80 kg N/ha and 4 seedlings/hill gave significantly highest yield (32.65 q/ha), followed by 40 kg N/ha and 4 seedlings/hill. On the basis of pooled data of 3 years, the yield response was 29 q/ha at the optimum dose rate of 40 kg N/ha.
