Effect of nitrogen and zinc on growth and yield of sweet corn article type

Abstract

The field experiment which was conducted during the kharif season of 2023 at Crop Research farm, Department of Agronomy. In which the treatments consisted of 3 levels of nitrogen (100 kg/ha, 125 kg/ha, and 150kg/ha) and zinc (0.2, 0.3 and 0.5%) with recommended doses of phosphorus and potash and a control (120-60-40 kg N-P-K/ha). The experiment which was laid out in a Randomized Block Design with 10 treatments and replicated thrice. The application of 150 kg/ha nitrogen along with foliar spray zinc 0.5% (Treatment 9) recorded highest dry weight (124.41 g), cobs per plant (2.90), rows per cob (20.50), grains per row (34.33), cob yield (6.53 t/ha) and green fodder yield (15.30t/ha).
