The experiment used a split-plot design with four levels of lime(control, 0.2, 0.4and 0.6 t ha-1) in main plots and four ricebean cultivars(RBS-16, RBS-53, PRR-2, and RCRB-4) in sub-plots with three replicates. The results revealed that increasing levels of lime(in the furrow)from 0 to 0.6 t ha-1significantly increased growth, yield attributes and yield. The quality parameters of ricebean were also influenced significantly by the application of lime. Maximum gross return(INR 39,098 ha-1), net return(INR 27,281 ha-1), benefit:cost(B:C) ratio(2.29),production efficiency, and economic efficiency were also realized with the application of lime at 0.6 t ha-1. Among the ricebean cultivars, RBS-53 produced significantly higher growth, yield attributes, grain yield, straw yield, biological yield, and harvest index. Similarly, yield and protein content were higher in RBS-53. Maximum gross return, net return, B:C ratio, production efficiency, and economic efficiency were observed for RBS-53.展开更多
