2 and 0.4 t ha− 1 treatments (Table 2). The pooled data in Table 3 showed that maximum gross return (INR 39,098 ha− 1), Ribociclib cell line net return (INR 27,228 ha− 1), B:C ratio (2.29), production efficiency (11.12 kg ha− 1 day− 1) and economic efficiency (INR 328.38 ha− 1 day− 1) were realized with 0.6 t lime ha− 1. The level of lime had a significant influence on pH, soil organic carbon (SOC),

and available soil N, P and K (Table 3). Application of lime at 0.6 t ha− 1 significantly increased pH, SOC, and available soil N, P and K over lower rates of lime (0, 0.2 and 4.0 t ha− 1). Cultivar RBS-53 had significantly greater plant height, branches plant− 1, trifoliate leaves plant− 1, dry matter plant− 1, root length, root dry weight, root volume, crop growth rate and leaf area index than did RCRB-4, RBS-16 and PRR-2 (Table 1). Similarly, pooled data showed that yield attributes including pods plant− 1, pod length, grains plant− 1, filled pods plant− 1, pod filling (%) and 1000-grain weight were significantly greater for RBS-53 than other cultivars. Cultivars RCRB-4 and RBS-16 were similar in terms of yield attributes and were significantly higher than PRR-2. Among the cultivars, RBS-53 produced significantly higher grain, straw and biological yields than did RCRB-4, RBS-16 and PRR-2.

Vorinostat in vivo Cultivar RBS-53 produced 23.2%, 14.1% and 18.6% higher grain, straw and biological yield, respectively than PRR-2. Similarly, cultivar RBS-53 had significantly higher protein content and protein yield than the other cultivars (Table 2). The maximum gross return (INR 33,639 ha− 1), of net return (INR 23,869 ha− 1) and B:C (2.36) were observed for RBS-53 (Table 3). The lowest gross

return (INR 27,690 ha− 1), net return (INR 17,920 ha− 1) and B:C ratio (1.86) were observed for PRR-2. Production efficiency and economic efficiency were also significantly greater for RBS 53 than for the other cultivars (Table 3). The pooled data showed that the interaction effect of levels of lime and ricebean cultivars on seed yield was significant (Table 4). The maximum (1.21 t ha− 1) seed yield was recorded at 0.6 t ha− 1 for RBS-53. A quadratic relationship between lime application and grain yield was fitted. The relationship between lime and grain yield could be expressed by high coefficient of determination (R2 = 1) ( Fig. 1). From the regression equation, the most profitable rate of lime application was estimated to be 0.556 t ha− 1 to achieve the maximum grain yield. The application of lime at up to 0.6 t ha− 1 produced significantly higher growth traits in the present study. This result could be attributed to higher photosynthesis and better translocation to the fruiting sink due to liming. The increase in vegetative growth with liming may result from better availability of nutrients due to moderation of soil reaction [15]. It may also be due to increased biological N fixation.
