Effect of spacing and nitrogen on growth and yield in pearl millet

Abstract

A field experiment was conducted during Kharif season 2022-2024 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on Pearl millet. The soil of the experimental plot had a sandy loam texture, low organic carbon (0.72%), a nearly neutral pH (7.2), nitrogen (178.48 kg/ha), phosphorus (27.80 kg/ha), and potassium (233.24 kg/ha). The experiment was conducted using a randomized block design with nine treatments, each replicated three times. The results revealed that significantly higher plant height (189.43 cm), dry weight (53.33 g/plant), number of ears/m2 (38.09), number of grains/ear head (1666.67), seed yield (2.76 t/ha), stover yield (5.53 t/ha) and harvest index (33.57%) were obtained in treatment T6 (45 cm × 10 cm + 90 kg/ha N) in Pearl millet crop.
