Effect of Tillage, Raking and Weeding on the Growth, Yield and Economics of Aus Rice (cv. BR 20)

Abstract: The experiment was conducted to evaluate the performance of Aus rice (CV. BR 20) under variable management. The treatments consisted of three tillage (Viz. 1 tillage, 2 tillage and 4 tillage) and three cultural practices (Viz. 2 raking, 2 weeding and 2 raking + 2 weeding). The Aus rice increased yield both for more tillage and cultural practices. Significantly, the highest grain yield (2.92 t ha-1) was obtained from 4 tillage with 2 raking and 2 weeding at 15 and 30 days after sowing (DAS). Though the treatment, 4 tillage with 2 raking and 2 weeding gave the highest yield but the benefit cost ratio (BCR) was found to be low (1.08) in this treatment. One tillage and two raking (15 and 30 DAS) was economically profitable practice with grain yield of 2.51 t ha-1 which also gave gross return of TK. 21520 ha-1, net return TK. 8731 ha-1+ and BCR 1.68.
