Division of Crop Rotation Research for Lowland farming

Demand for domestic agricultural products is increasing, however, for soybeans and wheat, the planted area and yield per area in prefectures other than Hokkaido are stagnant or declining. The paddy fields in the Kanto and Tokai region are large production areas for soybeans and wheat. However, soybeans have low yield and wheat has issue of large fluctuations in yield and quality. In addition, it is urgent to control the supply-demand balance of rice, wheat and soybeans and improve the self-sufficiency rate of soybeans and wheat by introducing long-term upland crop rotation and improving the productivity of field crops. Based on this background, we proceed research aiming at 1) developing cultivation improvement and growth control technology based on the acquisition information of fields and crops using various smart technologies for the upland crop rotation, 2) presenting a sustainable upland crop farming model that enables 20% improvement in soybean yield, 10% improvement in wheat yield, and grain protein optimization by optimizing crop rotation for stable production under sustainable field rotation.
