An investigation on the “Response of sweet corn hybrid to varying nitrogen and phosphorus levels” was conducted during summer season, 2015 at College of Agricultural, Junagadh. Treatment consisted four sweet corn varieties viz., Bajaura sweet corn, Sugar 75, Win Orange and Priya and three levels of fertilizers (90-40, 120-50 and 130-60 kg N-P2O5 ha-1). Nitrogen and phosphorus concentration and uptake was found significantly highest in sweet corn variety Sugar 75 over the rest of varieties but potassium content remain unaffected by sweet corn verities. Significant increase in NPK uptake by crop and were recorded with application of fertilizer 120 kg N + 50 kg P2O5 ha-1.
