Effect of Formulated Fertilization on Growth and Productivity of Coix in Xingren County
摘要
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 .关键词
