Abstract: 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., V 1 (JM 216) and V 2 (JM 218), and the second was six nitrogen scheduling, i.e., N 1 to N 6 , in which nitrogen splitting was done based on 30-years of average rainfall data. Variety JM 218 and N 5 [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 N 5 nitrogen schedule would be a better choice than alternative options.
