Abstract

A pot experiment was conducted to evaluate the effect of Cow Dung (CD) and Rice Hull (RH) on yield response of rice (BRRI 65) in a manipulated soil (acid soil: calcareous soil=7:3). Cow dung treatments were 0, 5 &10 t ha-1 and rice hull treatments were 0, 2&4 t ha-1. To assess the best mixing proportion an incubation study was carried out in the Department of Soil, Water and Environment, University of Dhaka. In case of soil, the pH, organic carbon and nutrients (N, P, K, S, Ca and Mg) status of manipulated soil were favorably influenced in manipulated soil. After harvest, the content of organic carbon decreased than the initial soil. Combined application of cow dung and rice hull influenced the available nutrient content (N, P, K, S, Ca and Mg) of the post-harvest manipulated soil. N, P, K, S, Ca and Mg showed better performance in post-harvest manipulated soil than individual acid and calcareous soil. Effects of CD (0, 5, 10 t ha-1) and RH (0, 2, 4 t ha-1) in response to rice (BRRI 65) in manipulated 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.
