Effect of nitrogen and phosphorus on growth and yield attributes of sweet corn

Abstract

A field experiment was conducted during Rabi 2023 at Crop Research Farm, Department of Agriculture, Ideal college of Arts and Sciences, Vidyut Nagar, Kakinada, Andhra Pradesh. The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice on the basis of one year experimentation. The treatments consisted of 3 levels of Nitrogen (80, 100, 120 kg/ha), and Phosphorus (40, 60, 80 kg/ha) and a control. Application of Nitrogen (100 kg/ha) + Phosphorus 80 kg/ha (Treatment 9) recorded maximum Plant height (221.47 cm), Dry weight (91.01 g) per plant, Number of cobs per plant (2.17), Number of rows per cobs (16.47), cob yield (6.46 t/ha).
