A field experiment was carried out at College of Agriculture, Navile, Shivamogga during kharif 2016 to study the response of maize to different phosphorus (P) levels with and without PSB seed treatment. The P levels were 0, 30, 45, 60 and 75 kg P2O5 per ha-1 with and without PSB seed treatment were tried in a randomized complete block design with three replications and eleven treatments. The results of the experiment indicated that seed treatment with PSB and higher levels of P significantly increases the growth, yield and yield attributes and uptake of nutrients by maize. Among the treatments, treatment receiving 75 kg P2O5 per ha-1 through DAP and PSB seed treatment recorded higher plant height (207.15 cm), total dry matter accumulation (116.65 g plant-1), and yield parameter like cob length (16.19 cm), cob weight (161.07g plant-1), test weight (37 g), grain yield and stover yield (55.07 and 76.48 q ha-1, respectively), and nutrient content and uptake of N, P, K by maize were also increased compared to other treatments and was on par with 75 kg P2O5 per ha-1 without PSB seed treatment and 60 kg P2O5 per ha-1 with PSB seed treatment. The experiment evidently proved that P application @ higher levels with PSB seed treatment could enhance the growth, yield and yield attributes, nutrient content and uptake by maize.
