Abstract

                                Studies on the chemical composition viz., nitrogen, phosphorus, potassium, starch ash contents and protein quality in certain sorghum varieties showed that all the varie- ties tested differed significantly in nitrogen, potassium and starch contents, while the phosphorus and ash contents showed no significant differences. All the varieties differed significantly in their protein content and showed no statistical significance as far as leucine content is concerned. Simple correlations showed significant nega- tive correlation between nitrogen and leucine, potassium and leucine and grain yield and leucine. Ash and starch content showed significant positive correlation, Energy values of different varieties, calculated based on starch content varied from 1109.11 to 1315.39 calories per Lb. of sample.
