Abstract
In trials in 1967-8, sorghum cv. CSH-1 and Swarna, grown at a stand density of 91 000-272 000 plants/ha and given 0-180 kg N/ha, gave average grain yields of 4.48 and 3.26 t/ha, respectively. Application of 120 kg N/ha gave the highest yields of 4.87 t/ha, compared with 2.13 t/ha in plots given no fertilizer. Increases in stand density were accompanied by linear increases in yields from 3.66 to 4.12 t/ha. The economic optimum N rates for CSH-1 and Swarna were 132 and 140 kg/ha, respectively. Grain protein contents increased with increasing N rates and with decreasing stand density. A rapid increase in N uptake occurred at 75 days after sowing.
