A field experiment was conducted during kharif season of 2012 on calcareous soil to study the effect of 4 levels of nitrogen and 3 levels of phosphorus on yield and yield attributes of maize in South Saurastra. N (60, 80, 100 and 120 kg ha-1) and P (40, 50 and 60 kg P2O5 ha-1) with twelve treatment combinations tested in factorial randomized block design with three replications. Results indicated that application of 120 kg N ha-1 recorded the maximum plant height (165.28 cm), number of cobs per plant (1.49), cob length (17.87 cm), cob girth (15.05 cm), dry matter accumulation (153.09 g plant-1), number of grains per cob (283.19), 100 grain weight (26.70 g), grain yield (4905 kg ha-1), stover yield (8478 kg ha-1), biological yield (13382 kg ha-1), net return (39228 ha-1) and BCR (3.14). Application of 60 kg P2O5 ha-1 recorded the maximum plant height (159.16 cm), number of cobs per plant (1.47), cob length (17.58 cm), cob girth (14.99 cm), dry matter accumulation (146.52 g plant-1), number of grains per cob (275.74), 100 grain weight (25.27 g), grain yield (4987 kg ha-1), stover yield (8281 kg ha-1), biological yield (13268 kg ha-1), net return (38967 Rs. ha-1) and BCR (3.03).
