Effect of different levels, split and foliar application of nitrogen on growth and yield of sweet corn (Zea mays var. saccharata)

Abstract

The goal of this research carried out at Faculty of Agriculture of Navsari Agricultural University of Navsari, during rabi season in 2017-18 was to determine the influence of different splits of nitrogen rates with and without foliar application of 2% urea on growth and yield of sweet corn (Zea mays var. saccharata). Experiment was laid out in factorial randomized block design with three replications. 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 results revealed that plant height at 60 DAS and at harvest, leaf area at 60 DAS, dry matter accumulation at harvest, number of grains and cob weight had significant results when 100% RDN applied in 3 splits while 100% RDN applied with 2% urea at 50 DAS, plant height at harvest, chlorophyll SPAD value at 60 DAS and dry matter accumulation at harvest were found significant superior. Significantly higher cob and fodder yield recorded in case of 100% RDN, 3 splits and foliar application of nitrogen.
