Abstract: A field experiment was conducted during kharif, 2018 at Agricultural College Farm, Mahanandi to assess “Effect of plant density and nitrogen management on yield and quality of sweet corn (Zea mays var Saccharata)”. Among the plant densities tried, plant density at (D1) 60 cm X 15 cm recorded that highest uptake of N, P2O5 and K2O by the crop at all the growth stages. Among the nitrogen levels tried, application of (T5) 125% RDN + FYM @ 10 t ha-1 at 25, 50 DAS and at harvest recorded the highest uptake of N, P2O5 and K2O which was however, found parity with (T4) 100% RDN + FYM @ 10 t ha-1. Among the plant densities 60 cm X 20 cm recorded higher total sugar, starch and amylose content over the other plant densities. Application 100% RDN + FYM @ 10 t ha-1 recorded significantly higher total sugar, starch and amylose content over rest of the treatments. Among the plant densities 60 cm X 20 cm recorded higher available nitrogen and 60 cm X 25 cm recorded higher available phosphorus and potassium available in soil after the harvest over other treatments. The maximum available nitrogen, phosphorus, potassium in soil was recorded with the application of 125% RDN + FYM @ 10 t ha-1 and it was on par with 100% RDN + FYM @ 10 t ha-1.
