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.
进行了一项盆栽试验，以研究不同水平的微量营养素（0、2、4和8克/5千克土壤）以及固定量（6克/5千克土壤）的大量营养素肥料对连续种植两个季节的高粱品种（Gadambalia）籽粒的抗营养成分、蛋白质含量和消化率、总宏量和微量元素以及可提取宏量和微量元素、氨基酸含量和评分的影响。两个季节中，高粱籽粒的蛋白质含量和必需氨基酸组成均随微量营养素水平的增加而显著（P≤0.05）提高。两个季节和处理中，单宁和植酸含量均显著（P≤0.05）下降，同时蛋白质消化率、宏量和微量元素的可提取性增加。两个季节中，籽粒的宏量和微量元素含量均随微量营养素水平的增加而增加。两个季节和处理中，籽粒的必需氨基酸评分均显著（P≤0.05）提高。
