The groundnut cultivar JL 24 was tried during 2012 with eleven ratios of nitrogen (N) and phosphorus (P2O5) fertilizers with potassium level as constant (25 kg K2O ha-1) at UAS, Dharwad. The yield attributing characteristics, dry pod yield and economics were increased due to increasing N/P fertilizer ratios from 0.00 to 1.00. The treatment receiving N/P fertilizer ratio of 0.50 (30 kg N, 60 kg P2O5, 25 kg K2O ha-1) produced significantly higher dry pod yield (3310 kg ha-1), 100 kernel weight (38.50 g). Maximum gross monetary returns and net monetary returns (Rs. 1,25,780 ha-1 and Rs 1,01,426 ha-1) and highest B : C ratio of 4.16 in the treatment receiving N/P fertilizer ratio of 0.50 (30 kg N, 60 kg P2O5, 25 kg K2O ha-1) produced higher kernel yield (2441 kg ha-1). as compared to all other treatments and control (Rs 83,372 ha-1 and Rs 62,904 ha-1) B: C ratio was recorded is lowest (3.07).
