Abstract
As a part of the study on the causes of the decrease in yield of black soybeans in converted fields in Kyoto prefecture, we examined the annual changes in the yield of continuous cropping of black soybean and the chemical properties of the soil in the converted gray lowland paddy field. The yield of grains increased in the third year after field conversion, and gradually decreased after the fourth year. The number of pods increased in the third year, and remained at the same level thereafter. The 2L size ratio of grains (weight ratio of grains larger than 10mm in diameter to total grains harvested) was still high for three years after conversion, and then decreased greatly after the fourth year. The number of nodules decreased gradually after conversion, and greatly after the fourth year. The decrease in the contents of total carbon and nitrogen in the paddy soil was not observed after conversion. The application of cattle manure composted with bark (CMCB) mitigated the decrease in the nodule formation, but not that in the 2L size ratio of grains. The amount of available soil nitrogen in the fifth year after conversion with CMCB application was higher than that in the non-converted paddy field without CMCB application.
