Effect of spacing and nitrogen levels on nutrient contents and their uptake in hybrid pearl millet

The experiment entitled “Effect of crop geometery and nitrogen levels on growth and yield of newly develop pearlmillet hybrid HHB197” was conducted at Research farm, Choudhary Charan Singh Haryana Agricultural University, Hisar during Kharif season of 2007. Four spacing patterns viz., 45 x 12, 45 x 16, 60 x 12 and 60x16 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. With each successive increase in nitrogen dose there was significant increase in N and P content in grain, stover as well as uptake by grain and total uptake upto the highest dose of N i.e. 160 kg N ha-1. Plant spacing 45×16 cm recorded significantly highest N, P and K uptake by grain as compared to other spacing treatments. Higher K content in grain was recorded under 60×16 cm spacing treatment which was significantly higher.
