| Outline of Final Research Achievements |
Silvoarable system as one of agroforestry, which combine log-grown shiitake mushroom production with beef cattle production in Japan, has been practiced to use primary factors of production for both departments. Therefore, integrative power of this silvoarable system is much stronger and its profitability is higher than mushroom or beef cattle specialized farming. It’s also cleared that its profitability is stable to fluctuation of each sales price through model analysis. It's cleared that productivity and profitability are quite different from pregnant cow’s seasonal grazing to all cattle year-round grazing. Therefore, it’s essential to promote the later grazing method to conserve agricultural land and to improve farming revenue. Furthermore, we analyzed several risks for cattle grazing on paddy fields and suggested the ways avoids and lowers these risks.
