説明

<p>The use of paddy fields for feed production has become an important issue in Japan in terms of adjusting rice production under the conditions of a decline in rice consumption and the need to improve feed self-sufficiency. However, studies of the effects of measures that promote the practical use of paddy fields to increase production of domestic feed under the conditions of a decline in farming population and financial budget restrictions, have not been carried out. Also, it is indispensable for paddy farmers to have studies conducted on the optimal kinds of feed by production size in order to assess the possibility of earning a profit from feed production.</p><p>Therefore, the purpose of this report is to build a liner program for comprehensive economic evaluation based on the analysis of yields, harvesting labor, production costs from feed rice, whole crop rice, whole crop corn, and grass on paddy fields, to clarify a favorable combination of each feed and their scale from the view point of compensation and year-round hiring of workers.</p><p>The results indicate that adoption of direct seeding of rice on dry fields and diversification of feed production into crops such as corn and grass are beneficial in terms of lower required investment, lower labor requirements, higher profitability, and seasonal equalization of work, when compared to food rice production executed through a system based upon transplantation of rice seedlings.</p><p>The results also suggest that present measures for feed production on paddy is not always efficient for promotion of the practical use of paddy fields and increased production of domestic feed because policies to encourage farmers to plant feed rice limits their ability to expand farm scale.</p>
