Nutritional quality of grains of sorghum cultivar grown under different levels of micronutrients fertilization.
A pot experiment was carried out to investigate the effect of different levels of micronutrients (0, 2, 4, and 8 g/5 kg soil) and a fixed amount (6 g/5 kg soil) of macronutrients fertilizer on the antinutrients content, protein content and digestibility, total and extractable macro- and micro-elements, amino acid content and score of grains of sorghum cultivar (Gadambalia) grown for two consecutive season. Protein content and essential amino acids composition of sorghum grains significantly (P⩽0.05) increased with micronutrients level for both seasons. Tannins and phytate contents dropped significantly (P⩽0.05) with a concomitant increase in protein digestibility, macro- and micro-elements extractability for both seasons and treatments. The content of macro- and micro-elements of the grains increased with micronutrients level during both seasons. The essential amino acids scores of the grains were significantly (P⩽0.05) increased for both seasons and treatments.
