Abstract

Abstract: To study the effect of narrow-row no-till on soybean root, grain yield and quality, three treatments were set including 30 cm narrow-row no-till (NT1), 19 cm narrow-row no-till (NT2) and 68 cm traditional tillage (CT). The results indicated that dry and fresh root weight per plant of NT1 and NT2 were significantly lower than that of CT. However, the dry and fresh root weight of group of NT1 and NT2 were significantly higher than that of CT. Narrow-row no-till had significant effects on soybean yield, yield component and agronomic traits, and the grain yield of NT1 and NT2 was 27.8% and 22.1% higher than that of CT, respectively. There was no significant difference in grain protein content, fat content, and total protein-fat proportion among the three treatments. However, significant difference was found in total fat content, total protein content and total protein- fat content. Total fat content and total protein content of NT1 were significantly higher than that NT2, which were significantly higher than that of CT. The total protein- fat content had no significant difference between NT1 and NT2, but it was significantly higher than that of CT.
