Abstract

During zaid season, a field investigation study was conducted at crop research farm, Sam Higginbottom University of Agriculture, Technology and Sciences to find out the effect of growth and yield attributing characters of sweet corn (Zea mays L.) in relation to three planting geometries and levels of phosphorus grown in Uttar Pradesh. A Randomized Block Design was followed with nine treatment combinations and three replications based on the factors of planting geometry (60 cm × 15 cm, 60 cm × 20 cm and 60 cm × 25 cm) and phosphorus levels (P at 45, 60 and 75 kg/ha). Growth characters such as plant height (173.67 cm), number of leaves (9.33/plant), dry weight (115.32 g/plant) was noticed maximum in 60 cm × 25 cm + P at 75 kg/ha but CGR (50.83 g/m2/day) was recorded in 60 cm × 15 cm + P at 75 kg/ha and RGR (0.0457 g/g/day) in 60 cm × 15 cm + P at 45 kg/ha. Yield attributes such as cobs (1.33/plant), grain rows (16.33/cob), grains (28.13/row), cob length (20.63 cm) and seed index (2
