Laboratory of Cropping Systems(Miyakonojo)

Development of cropping systems and improvement of crop productivity have been studied for upland crops in our laboratory. Particularly sweet potato is one of the main upland crops in the southern part of the Kyushu district. Then we attempted to analyse the effect of cultivation conditions on the yield and the properties of tuberous roots. The research themes relating to sweet potato are as follows:
  1. Analysis of the relationship between the cropping systems and yield or tuberous root properties.
  2. Investigation of the effect of crop management on the yield and pigment content of tuberous roots.
