Abstract
In 2 successive years the accumulation of nitrogen by this sorghum (Sorghum bicolor) hybrid increased upto 60 days in the stem and 75 days in the sheath and leaves, and decreased thereafter. Application of N markedly increased N uptake in the whole plant at all stages. At harvest the percentage recovery of N in the two years was 53.8 and 56.4 in the panicle, 22.5 and 22.2 in the leaf, 14.8 and 13.5 in the stem, and 8.9 and 7.9 in the sheath. N uptake by the plant increased with N application up to 200 kg/ha, but increases in yields of grain and of the rest of the plant became lower above 120 kg N/ha. Different times of N application did not significantly affect yields and total N uptake. Plant recovery of N decreased with increasing application of N.
