Timely tilling and seeding are major challenges in crop production specially after harvesting of Aman rice. The problem can be solved using power tiller operated seeder (PTOS). Different tillage and planting methods were implied in farmers’ fields for maize in Patuakahli and Rajshahi during rabi seasons of 2018-19 and 2019-20. The experiment was laid out with RCBD design with four treatments and three replications. The treatments were power tiller operated seeder with full tillage (PTOS), strip tillage (ST), zero tillage (ZT) and conventional tillage cum manual planting method (CT). Farmers unit plot area of about 0.40 ha (One Bigha) land was selected for this experiment considering uniform land type, soil type and cropping pattern. PTOS was found effective in tilling and planting of maize in all locations. Significantly the highest grain yield was found from PTOS than ST, ZT and CT. The BCR (benefit cost ratio) of PTOS and CT methods were found 1.54 and 1.08, respectively. The PTOS saved time preventing late sowing and also reduced labour curtailing crop production cost. So, the BARI developed PTOS can be recommended for reduced tillage practices for planting of maize in Bangladesh.
