Abstract
The purpose of this study is to establish the mechanized working system of simultaneously planted Barley and Taro cultivation in Autumn on a practical scale, and to evaluate an effect on saving of the fuel consumption.
The results obtained are as follows;
1. The cultivation system of combined Barley and Taro by simultaneous planting were established without having a bad influence on the growth of both crops.
2. In the simultaneously planted Barley and Taro cultivation system, the machine working hours in test fields were ranged from 5.26 to 5.40hr/10a and the working hours were ranged from 24.20 to 27.14man·hr/10a. Fuel consumption were ranged from 11.53 to 11.83l/10a.
3. In the control test plot (Taro cultivation after barley harvesting), the machine working hours was 7.31hr/10a, the working hours was 23.18man·hr/10a and fuel consumption was 16.46l/10a.
4. Fuel consumption of simultanseously planted Barley-Taro cultivation was lesser than that of the control test plot (Barley-Taro cultivation).
5. It was found that the production of carbon dioxide of new cultivation system (simultaneously planted Barley and Taro cultivation) was 30% less than that of control test plot.
6. It was shown that the techniques, developed indivividual working researches, could be applicable to simultaneously planted Barley-Taro cultivation on practical scale.
