A field experiment was conducted during kharif season of 2018 at WALMI farm, UAS, Dharwad to study the response of sweet corn (Zea mays L. saccharata) to split application of nitrogen and potassium with protective irrigation. The experiment was laid out in factorial RCBD with three replications. There were two factors Viz., fertilizer levels (L₁:100:50:25, L₂:125:60:25 and L₃:150:65:65) and split application of nitrogen and potassium (S₁: Two equal split as basal and 30 DAS, S₂: Three equal splits as basal, 30 and 45 DAS and S₃: P and K as basal and N in three equal splits as basal, 30 and 45 DAS). Among the fertilizer levels, application of 150:65:65 N:P₂O₅:K₂O kg ha^-1 recorded significantly higher fresh cob yield (150 q ha^-1) and fresh fodder yield (245 q ha^-1) compared to application of 100:50:25 N:P₂O₅:K₂O kg ha^-1. However, it was on par with 125:60:25 N:P₂O₅:K₂O kg ha^-1. Among split application, three split application of N and K as basal, 30 and 45 DAS recorded significantly higher fresh cob yield (153 q ha^-1) and fresh fodder yield (247 q ha^-1) as compared to application of P and K as basal and N was applied in 3 equal split doses (as basal, 30 and 45 DAS). However, it was on par with split application of N and K in two equal splits (as basal and 30 DAS).
