摘要： Foxtail millet (Setaria italica (L.) P. Beauvois) is a high-nutrition food source. It is commonly consumed in Africa, Asia, Central America, and South America. The key to popularize high-quality foxtail millet in accordance with local conditions is quantifying the impacts of cultivation conditions on its quality. Here, we determined the effects of different fertilizer levels nitrogen (N), tetraphosphorus decaoxide (P2O5), and potassium oxide (K2O), tribenuron-methyl (TBM) herbicide, and selenium (Se) on the quality of foxtail millet Jingu 54 using a quadratic general rotation combination design. The first principal component, which could explain 57.41% of the total variance of grain quality, was chosen as the comprehensive quality of Jingu 54 via principal component analysis. The effects of fertilizer levels and Se on comprehensive quality of Jingu 54 were significant (P < 0.05), except for TBM. The effects of N x K2O, N x TBM, and K2O x TBM interactions reached significance for the comprehensive quality of Jingu 54 (P < 0.05). The grain quality of Jingu 54 was predict by regression equation (P = 0.0048, R-2 = 0.8451). Recommended cultivation conditions are 108.31 kg ha(-1), 94.80 kg ha(-1), 105.03 kg ha(-1), 88.08 g ha(-1), and 18.48 g ai ha(-1) for N, P2O5, K2O, Se, and TBM, respectively. The maximum predicted comprehensive quality of Jingu 54 was 56.85. This study lays a theoretical foundation for achieving high quality Jingu 54 in the field.
