EFFECTS OF COW DUNG AND RICE HULL ON THE GROWTH AND YIELD OF RICE GROWN IN THE MIXED SOIL

Effects of cow dung (CD) (0, 5, 10 t ha-1) and rice hull (RH) (0, 2, 4 t ha-1) in response to rice (BRRI 65) in mixed soil showed that agronomic attributes such as height, number of tillers and dry weight of rice plant increased significantly due to addition of CD and RH alone and their combinations. However, dry weight of rice plant did not increase due to interaction of their highest doses. Yield attributes like number of grains and yield of grain increased due to application of CD and RH alone and in combination but in case of yield of grain the trend was erratic. Moreover, the yield index, i.e., 1000-grain weight showed no definite trend due to treatments applied. Contents of N, P, K, S, Ca and Mg of shoot and grain showed an increase with the increase of doses of CD and RH alone. Interaction between CD and RH in case of P, Ca and Mg content in shoot and grain showed an almost similar result. N, K and S content of shoot and grain increased with the increase of doses due to interaction of amendments.
