A field experiment was conducted during rainy season of 2014 under All India Coordinated Research Project on Groundnut at University of Agricultural Sciences, Dharwad, Karnataka to find out the effect of spacing and nutrient on AVT groundnut cultivar K 1641 in black soils under rainfed condition. The highest pod yield (3578 kg/ha) was found in the K 1641 as compared to check variety TGLPS 3(3194 Kg/ha). A plant spacing of 30 cm x 10 cm gave the highest pod (3845 Kg/ha) as compared to wider intra row spacing (30 cm x 20cm) (2927 kg/ha). Among the nutrient management practices, recommended dose (100%) of NPK resulted in significantly higher pod yield (3488 kg/ha) as compared to 50% recommended dose of NPK (3120 kg/ha) and failed to respond to higher level (150%) of recommended dose of NPK (3549 kg/ha). Whereas, Cultivar K 1641 responded to higher dose of nutrient application i.e. Application of FYM @ 7.5 t ha-1 + 150 % RDNPK (37.5 kg N, 112.5 kg P2O5 and 37.5 kg K2O ha-1) and registered higher net monetary returns(Rs.103013 ha-1) and B:C ratio (2.88).
