To evaluate the response to lime on cultivars of ricebean (Vigna umbellata), a field experiment was conducted during the two consecutive rabi seasons of 2010–2011 and 2011–2012 in the Nagaland foothills, India. The experiment used a split-plot design with four levels of lime (control, 0.2, 0.4 and 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^− 1 significantly 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.

Interestingly more than 50% of the world’s area is rainfed and approximately 80% of maize is cultivated under rainfed condition where selection of cultivar and management of nitrogen have major impact on production. The aim of this study was to evaluate the growth, phenology, yield and quality parameters of maize as influenced by variety and nitrogen scheduling under rainfed condition. For this, a field experiment having two factors was laid out in a factorial randomised block design and replicated three times. The first factor was variety, i.e., V₁ (JM 216) and V₂ (JM 218), and the second was six nitrogen scheduling, i.e., N₁ to N₆, in which nitrogen splitting was done based on 30-years of average rainfall data. Variety JM 218 and N₅ [40 kg N as basal followed by (fb) 2 splits of 40 kg N and 38.8 kg N at 30 and 52 days after sowing (DAS) and 1% N foliar spray at 40 DAS] nitrogen scheduling were found promising under rainfed situation because it recorded maximum value of growth parameters, yield attributes, grain yield and quality parameters (protein, mineral and dickson quality index). Thus, it can be inferred that JM 218 and N₅ nitrogen schedule would be a better choice than alternative options.
