Abstract

This paper presents results of an investigation of farm work technology characteristics. A chisel in a fertilizer-applicator ditcher was constructed to improve Welsh onion cultivation. When the fertilizer-applicator ditcher was opening a ditch, work rates were 1.31-1.76h/10 a, widths were 50-52cm, depths were 16-19cm, and the bottom surface widths were 19-20cm. Fertilizer positions were 6cm from the center at the bottom surface to horizontal. Depths at these positions were 2-3cm. Depths of the chise were 11cm. Amounts of rectangle board settlement at the center at the bottom surface showed a significant difference between test blocks with chisel and test blocks with no chisel. The work rate for planting showed no differences among test blocks. However, test block with chisel and double drill fertilize exhibited the best rate of right planting at 86%. Planting postures were improved by soil softening of the shallow phase, which disturbs drill fertilizers in an open ditch with a transplanter.
