Description

<p>About rice production cost, fertilizer cost, and labor expense in California and in Italy (rice locality in developed countries in the West) are clearly lower than that of Japan. But their utility cost, agrochemical cost and depreciation for buildings are not quite different from Japanese ones. Seed cost is also expensive per unit weight. A case in Aomori has tractors like Italian make expensive in depreciation amount for machines, but it can reduce labor cost near to developed countries in the West. Ordinary combine harvester can be used in the U.S.A and in Italia about 5,000ha, but Japanese head-feeding combine harvester can be used lower than in that case in Aomori. So technological improvement and diffusion of ordinary combine harvester is important in Japan. Compared to water management which is notably labor-saving in Italy or in California, Italian wet direst seeding is needed more frequent labor than that of Japan. But Italian water outlet and migration is very less per area than that of Japan, so labor is saved in Italy. In California Irrigation operations are few. For labor-saving about water management, more extension of farm field will be expected in Japan.</p>
