Nutrient uptake by crop mainly depends on the dynamics of biomass accumulation during crop growing season. So a field investigation was carried out during kharif 2015-16 at Agricultural Research Institute, Professor Jayashanar telangana state Agricultural University Rajendranagar, Hyderabad with an object to find out the optimum sowing date and plant density. The experiment was carried out with three dates of sowing (26 June, 6 July and 16 July) as one factor and three plant densities 3,33,333 plants ha-1, 1,66,666 plants ha-1 and 1,11,111 plants ha-1 as another factor in RBD (factorial) design replicated four times. The study revealed that 26 June sown crop recorded significantly more dry matter production, nitrogen uptake, seed yield and haulm yield over 6 July and 16 July sown crop. Among plant densities of 3,33,333 plants ha-1 recorded significantly higher dry matter production, nitrogen uptake, seed yield and haulm yield.
