Abstract

Field experiments were conducted in summer and kharif, under irrigation, to study the effect of time and quantity of N application on the growth and yield components of sorghum (CSH-5). There was no significant difference in plant height due to different N treatments. Increase in N levels significantly decreased the number of days required for 50 per cent flowering. In summer, N levels had signi ficant influence on the leaf area per plant. Weight of grains per ear head was found to vary significantly due to N levels in kharif. In summer, N levels had highly significant influence on thousand grain weight. N management resulted in staining adequate growth and yield components which contributed to increased yield.
