Abstract

Cultivation techniques of proso millet (Panicum miliaceum L.) and foxtail millet (Setaria italica L.), such as sowing, weeding, and harvesting, are often not properly utilized, resulting in low productivity rates. The goal of this study was to develop cultivation techniques to increase millet productivity rates and reduce labor inputs. We evaluated the effects of different machine sowing methods compared with manual sowing methods from 2014 to 2016. The three machine sowing methods were dibbling, drilling, and broadcasting. Compared with manual sowing, the broadcasting method decreased labor times by 16.07 and 14.23 hr 10 a-1 for proso and foxtail millets, respectively. Proso millet showed greater culm lengths at 138 and 125 cm with the broadcasting method for two years, whereas foxtail millet after three years had greater culm lengths from both the drilling and broadcasting methods. Both crops exhibited the thickest culm stems in the 3rd year. The greatest number of seeds of the panicle were from the manual sowing method in both crops. Compared with manual sowing, broadcasting increased grain yields by 15–35% and 9.1–28% for proso and foxtail millets, respectively. Therefore, we suggest that the application of broadcasting in mechanical sowing will increase labor efficiency and yields of proso and foxtail millets.
