Effect of nitrogen and plant densities on growth and yield attributes of sweet corn

Abstract

A field experiment was conducted during Kharif 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice based on one year experimentation. The treatments consisted of three levels of Nitrogen (80, 100, 120 kg/ha), and Spacing (30 x 25 cm, 35 x 20 cm and 45 x 15 cm) and a control. Application of Nitrogen (120 kg/ha) + Spacing (45 x 15 cm) (Treatment 9) recorded maximum Plant height (204.52 cm), Dry weight (82.83 g) per plant, Number of cobs per plant (1.69), Number of rows per cobs (14.31), Number of grains per row (39.56), Green cob yield (5.02 t/ha).
