A 2-year field trial Nov-Jun 1985-1986 and 1986-87 was conducted to study the performance of rice after potato, mustard, and fallow with 0, 2, and 4 plowings per farmers' practice. Nine treatments were tested in a split-plot design with three replications. Soil belonged to Sylok series, silty clay loam texture. Potato and mustard were sown in Nov for both years. Potato received 102-100-100 and mustard 80-60-40 kg NPK/ha. After harvest, the land was tilled using a bullock. Rice, 45-d-old BR3 (Biplab) seedlings was transplanted at 25-x15-cm spacing with 80-60-40 kg NPK/ha. NPK was applied as urea, triple superphosphate, and muriate of potash. Highest yield of rice was after potato. Rice after mustard and in fallow gave identical yields. Rice yield increased with number of plowings.
