Abstract

On-farm research was conducted at Gouripur sub-district under Mymensingh district of Bangladesh during boro (mid November-June) season in 2013-14 and 2014-15 to evaluate the performance of unpadded rice cultivation with crop residue retention. The rice var. BRRI dhan28 was transplanted by two tillage practices viz., puddled conventional tillage (CT) and non-puddled strip tillage (ST) and two levels of mustard residues, i.e., no residue (R0) and 50% residue (R50). The experiment had designed in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2013-14. But in the following year, ST yielded higher grains (5.72 t ha-1), which was about 9.36 % higher compared to CT. The higher grain yield in ST, leading to 22.23% higher BCR compared to CT. Retention of 50% residue increased by 3.15 % yield compared to no-residue, which contributed to 10.58 % higher benefit-cost ratio (BCR). The ST combine with 50 % residue retention yielded the highest grain yield (5.81 t ha-1) which credited to obtain the highest BCR (1.06).
