Grains of pearl millet were rich in crude fat and iron as compared with most other cereal grains. Wide variation in the protein content ranging from 8 to 20 per cent, was observed in different varieties. The tiny embryo of the grain contained 10 per cent. of the total protein and was seven times richer in protein than the endosperm. Prolamins and glutelins were the major protein fractions but the relative proportions of these fractions in different varieties showed wide variations ranging from 21 to 38 and 24 to 37 per cent, respectively. Albumin and globulin fractions were found to be rich in basic amino acids lysine, argi-nine and histidine as well as in cysteine and methionine. The prolamins were extremely rich in glutamic acid, proline and leucine as well as in tryptophan, but poor in lysine. Maximum concentration of sulphur was found in the globulin fraction.
The main effect of nitrogen fertilization was to enhance the concentration of the prolamin fraction in HB. 1. Consequently concentration of lysine decreased and that of tryptophan increased in the protein.
