Abstract:
This paper briefly discusses the effect of different levels and split application of nitrogen with and without foliar spray of urea on nutrient uptake, yield and economics of sweet corn. Experiment was laid out in factorial randomized block design with three replications at Faculty of Agriculture of Navsari Agricultural University of Navsari, during rabi season in 2017-18. The research comprised of three level of recommended dose of nitrogen: 50%, 75% and 100% RDN; two levels of split application: basal fb 30 DAS, basal fb 20 and 40 DAS; and foliar application of nitrogen: control and 2% urea at 50 DAS. The result showed that significantly higher N content and N, P and K uptake in grain and fodder was recorded with application of 100% RDN and three splits with foliar application of urea. N uptake in grain and fodder showed significant interaction effects. While maximum gross realization, net return and B:C ratio were obtained with application of 100% RDN and three splits with foliar application of urea.
