Evaluation of Rice Cultivars Suited to Different Conservation Tillage System for Improved Water Productivity and Yield

Abstract

A field experiment was conducted in wheat during kharifseason 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 (Tz), Puddled-bed x PUSA-1121 (T3), Wide-bed x PUSA-1121 (T4), Narrow-bed x Vallabh basmati-22 (Ts), Nonpuddled- bed x Vallabh basmati-22 (T6), Puddled-bed x Vallabh basmati-22 (T1), and Wide-bed x x Vallabh basmati-22 (Ta). 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 (Ta), Puddled-bed x PUSA-1121 (T3), and Puddled-bed x Vallabh basmati-22 (T1 ), planting techniques respectively. Highest grain yield (59.01qjha-1), and straw yield (79.41 qjha-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), (f69633/ha) and (2.46), followed by Wide-bed x Vallabh basmati-22 (Ta) ((~69086.2/ha) and (2.13).
