We focus on the use of green manures, e.g., sorghum and hairy vetch, to decrease damage to cabbages caused by clubroot disease. Effect of green manures on soil fertility, and chemical, physical, and biological properties will be also identified. The results of this study can contribute to developing useful methods for protecting cabbages from clubroot disease without the high amount of agrochemicals. In addition, we focus on other study themes as well (please see below). All studies in our lab have the same target, which is to identify the solutions for providing safer agricultural products sustainably. ABio-resource Science DivisionStudy theme 1Identification of the effects of green manures to decrease clubroot of cabbage Study theme 2Identification of the effects of the in-organic or organic fertilizer application on cabbage growth and taste Study theme 3Identification of the root function of phosphorus uptake in runner beanGood growth condition of cabbage root (left) and infected root by clubroot disease (right).Continuous cultivated cabbages (left), cultivated cabbages after cultivation of hairy vetch (middle) and sorghum (right).Cabbages after green manure were better than continuous one.Continuous cultivated cabbage plot (left), hairy vetch plot (right back) and sorghum plot (right foreground).Continuous cultivated cabbage showed bad growth status due to infection of clubroot disease.
