Abstract
A study was conducted from 1999 to 2000 to determine the effects of seedling ages at transplanting (25, 40 and 55 days), number of seedlings per hill (one or two) and nitrogen rates (50, 100 and 150 kg/ha) on the yields of Sahyadri rice hybrid. A significant reduction in yield was observed with the delay in transplanting at 40- and 55-day-old seedlings over 25-day-old seedlings in 1999 and in the pooled mean of both years. The application of 150 and 100 kg N/ha resulted in significantly higher yields than treatment with 50 kg N/ha. Transplanting two seedlings per hill at 20x15-cm spacing produced significantly a higher yield than transplanting of one seedling per hill. The above treatment combinations resulted in the highest net returns (Rs. 5821) and benefit:cost ratio (1.212). Transplanting two 25-day-old seedlings per hill at 20x15-cm spacing with 150 kg N/ha is recommended for the commercial cultivation of Sahyadri rice hybrid.
