Growth, yield and quality parameters of soybean differed significantly on clayey textured soil with residualeffect of irrigation and fertilizer resources after maize at Dharwad during 2013-14 and 2014-15. Besides, experiment inmaize was laid out in split-split plot with irrigation levels in main-plots and factorial combinations of fertilizer levels withits applications in sub-plots. Residual effect of deficit irrigation at growth stages recorded higher protein content (36.8%),seed yield (11.4 q ha-1) and net assimilation rate (0.050 g dm-2 day-1). Similarly, residual effect due to fertilizer levels of250:100:125 kg N:P2O5:K2O ha-1 obtained significantly higher protein content (37.3%), seed yield (12.5 q ha-1) and netassimilation rate (0.049 g dm-2 day-1). Further, residual effect due to application of fertilizers as 33 per cent each (1/3rd) ofN, P2O5 and K2O as basal, 33 per cent each of N, P2O5 and K2O at 30 days after sowing and 33 per cent each of N, P2O5 andK2O at 50 days after sowing recorded higher protein content (37.0%), seed yield (11.8 q ha-1) and net assimilation rate(0.047 g dm-2 day-1). Similarly, interaction with respect to residual effect of deficit irrigation at growth stages and fertilizerlevels of 250:100:125 kg N:P2O5:K2O ha-1 with application of fertilizers as 33 per cent each (1/3rd) of N, P2O5 and K2O asbasal, 33 per cent each of N, P2O5 and K2O at 30 days after sowing and 33 per cent each of N, P2O5 and K2O at 50 days aftersowing recorded higher protein content (37.6%), seed yield (15.0 q ha-1) and net assimilation rate (0.055 g dm-2 day-1).
