Abstract: Effects of varied fertilizations on agronomic characteristics, dry matter accumulation, nutritional content, productivity and yield traits of coix in Xingren county, Guizhou was studied using a "3414" regression design. The results showed that the yield of coix were improved by the formulated N-P-K fertilizations as compared with CK (Treatment 1). The agronomic properties of the coix under the 20-5-15 and 20-10-7.5 formulations were better than the other 12 treatments. Among all treatments, the 20-5-7.5 formulation rendered the greatest yield, while the 20-5-15 exhibited the most significant effect on the accumulations of dry matters and nutrients. Based on a quadratic regression analysis, the fertilization with 16.45 kg N/667 m², 9.53 kg P₂O₅/667 m² and 14.49 kg K₂O/667 m² was recommended for coix cultivation in Xingren county.
