Effect of age of seedling and application of nitrogen on wet season rice

Field experiment conducted at BCKV Farm, West Bengal, with rice during wet season (2005-06) with two cultivars, seedling of two ages (25 and 35 days ) and three fertility levels (40 Kg N + 60 Kg P2O5 + 40 Kg K2O ha–1, 80 Kg N + 60 Kg P2O5 + 40 Kg K2O ha–1 and 15t FYM + 60Kg P2O5 + 40 Kg K2O ha-1 revealed that Khitish showed better performance over Satabdi increasing grain yield by 20.47%. Twenty five days old seedlings were superior to 35 days old seedlings resulting in increased grain yield by 4.90% and FYM @ 15 t ha–1 gave best result over 40 Kg and 80 Kg N–1 increasing grain yield by 18.41% and 5.89%, respectively. Maximum grain yield was associated with the highest no. of tillers m–2, no. of panicles m–2, length of panicle, filled grains panicle–1 and test weight. The decrease in yield as a result of transplanting of aged seedlings (35 days old) for both the cultivars was associated with corresponding decrease in yield components. For maximum grain yield (3.86 t ha–1) the best combination was transplanting of 25 days old seedlings of Khitish with FYM @15 t ha-1.
