Online published on 13 January, 2016. Abstract A field experiment was conducted in wheat during rabi season 2012–13 on sandy loam soil at Crop Research Centre, Chirodi of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). The experiment was conducted in R. B.D with three replications comprising keeping eight treatments of rice cultivars suited to different conservation tillage system. Narrow-bed x PUSA-1121 (T1), Non-puddled-bed x PUSA-1121 (T2), Puddled-bed x PUSA-1121 (T3), Wide-bed x PUSA-1121 (T4), Narrow-bed x Vallabh basmati-22 (T5), Non-puddled-bed x Vallabh basmati-22 (T6), Puddled-bed x Vallabh basmati-22 (T7), and Wide-bed x x Vallabh basmati-22 (T8). The results indicated that Planting technique Wide-bed x PUSA-1121 (T4), was observed highest in plant height, number of tillers, leaf area, dry matter accumulation, fresh weight per plant and test weight of followed by Wide-bed x Vallabh basmati-22 (T8), Puddled-bed x PUSA-1121 (T3), and Puddled-bed x Vallabh basmati-22 (T7), planting techniques respectively. Highest grain yield (59.01q/ha−1), and straw yield (79.41 q/ha−1), was recorded Planting technique Wide-bed x PUSA-1121 (T4), maximum net return and B-C ratio was recorded with Planting technique Wide-bed x PUSA-1121 (T4), (69633/ha) and (2.46), followed by Wide-bed x Vallabh basmati-22 (T8) ((69086.2/ha) and (2.13). respectively.
