Description

Eleven investigations of soil physical properties and thirteen investigations into the growth and yield of soybean were performed after twice cultivating-ridging using disk cultivator-ridgers (D) and rotary cultivators (Rm, R) in five fields planted with soybean. The following results were obtained. (1) When cultivating-ridging in wet soil conditions, the solid phase rate of the surface layer soil in the D-D plots before soybean harvesting was 0.95 times, that in the R-Rm plots, and 0.98 times in the R-R plots. The moisture content of the above-mentioned soil conditions in the D-D plots was 1.1 times that in the R-Rm plots. (2) For cultivating-ridging in wet soil conditions, the soybean yield in the D-D plots was 15 % higher than that in the R-Rm plots.
