Abstract
An experiment was carried out at Bangladesh Agricultural University Farm, Mymensingh during aman season of 2008 to study the effect of tillage intensity, fertilizer and manure on soil physical properties and rice yield (BRRIdhan 41). The experiment was laid out in split plot design with three replications. The treatments were, factor(A): tillage operation as; one passing (P1), two passing (P2) and three passing (P3) of a power tiller and factor(B): fertilizer and manure treatments as; recommended dose of fertilizer(FM0), 50% of N + rest of recommended dose of fertilizers + cowdung @ 5 t ha-1 (FM1), 50% of N plus rest of recommended dose of fertilizers + rice straw @ 5 t ha-1 (FM2) and 50% of N plus rest of recommended dose of fertilizer + cowdung @ 2.5 t ha-1 plus rice straw @ 2.5 t ha-1 (FM3). Results showed that the highest and the lowest bulk density of soil were found with P1FM0 (1.46 g cm-3) and P3FM2 (0.85 g cm-3) treatments, respectively. The maximum soil moisture content and air filled porosity were obtained in P3FM1 (55.4 and 15.34% respectively) treatment whereas P1FM0 demonstrated the lowest values (40.64 and 4.48% respectively). The highest grain yield (4.98 t ha-1) was recorded with P3FM0 treatment which was identical with those of P1FM0 and P2FM0.
Key words: Rice, Tillage, Fertilizer and Manure, Soil Properties and Yield.
