Abstract

In Miyazaki Prefecture, taro is cultivated in wide rows that allow for the use of tractors. We developed a labor-saving method for ridging work using a direct-mount-type hiller. This machine improves upon commercial up-cut rotary tillers in terms of the arrangement of the three rotary blades, the shape of the rotary cover, and the addition of a grass divider. The theoretical field capacity of this machine loaded on a 20-kW tractor is 0.16ha/h with the rotary tiller rotating at 316rpm and the machine running at 0.2m/s. For soil moisture contents of 35-59% and plowing depths of 51-166 mm, the plowing depth (x) and ridging thickness (y) were positively correlated (r=0.95), and the linear regression equation was y=1.03x-15.43. If soil contraction is considered, the required thickness of the ridges immediately after work is 135mm. The equation shows that a 149-mm plowing depth is necessary to obtain a 135-mm thickness. This study confirmed that the machine has sufficient capacity for ridging work for taro cultivation. The effective field capacity for supplemental application and ridging work by the machine was 2.9-3.6 times that of the traditional method. The yield equaled that of cultivation without ridging, and the quality of the product was higher than that of cultivation without ridging.
