Abstract
A comparative analysis of farm incomes was performed from the new composition system of crops, such as feed crops, including soybeans, Italian ryegrass, soybean-potatoes, and soybean-barley planted in rice fields. Through this analysis, the suggested implications were derived, and the technological solutions were determined. The profitability of the composition of soybean-Italian ryegrass showed that the soybeans yield was 325kg/10a, and the sale price was ￦3,962/kg, leading to a gross revenue of ￦1,288,000/10a. The yield of Italian ryegrass was 1,584kg/10a with a sale price of ￦125/kg, showing a gross revenue of ￦198,000/10a. The net income of soybeans was ￦284,000/10a, which means a net income rate of 22.1%, whereas the net income of Italian ryegrass was -￦30,000/10a. The composition of soybeans-potatoes and soybeans-barley showed a gross revenue of ￦930,000/10a and ￦375,000/10a, respectively. The crop composition types have been developed for the Income Type, Production Type of Forage, Improvement Type of Food Self-Sufficiency, and Corresponding Type to Climate Change. On the other hand, regional types have not been developed sufficiently. In addition, various selections of alternative crops and the establishment of crop composition congruent to the specific regions should be developed systematically in terms of the production technology. Therefore, it is necessary to develop the technological establishment of the crop composition through continuous related studies with the mid-to-long term objectives of land utilization and grain self-sufficiency rates.
