Effect of crop geometry and nitrogen levels on growth parameters and yield attributes of Pearl millet

Abstract

A field experiment was conducted during the kharif season of 2007 at Agronomy Research Farm, Chaudhary Charan Singh Haryana Agricultural University, Hisar to study the effect of crop geometry and nitrogen levels on growth and yield of newly develop pearl millet hybrid HHB197. Four spacing patterns viz., 45 x 12, 45 x 16, 60 x 12 and 60 x 16 cm and five nitrogen levels viz., control, 40, 80, 120 and 160 kg N ha-1 tested in factorial randomized block design (FRBD) with three replications. Plant growth in terms of height, dry matter accumulation plant-1, leaf area plant-1 increased significantly with increase in spacing at most of the stages of observations. Similarly, yield attributing characters like effective tillers plant-1, 1000 grain weight, length of earhead and girth of earhead increased significantly with increase in spacing.
