To evaluate the effectivity of ʻCoral gravel agricultureʼ on cherry tomato, we examined the effects of silicon and calcium included in solid medium on growth, yield and photosynthesis. Total fruit yield and total number of fruits were increased by silicon material in solid medium. Simultaneously, net photosynthetic rate at later growth stage was increased by silicon material. However, the yield and photosynthesis parameters were no affected by foliar spray of silicon. These effects indicate that the silicon thorough root was the important on yield and dry matter production of cherry tomato. Moreover, the calcium material in solid medium increased the total fruit yield in cherry tomato. The photosynthetic rate was slightly increased by calcium material, but the effects was not significant. Therefore, the calcium through root was the important factor in cherry tomato, but the importance of calcium was smaller than silicon. These results indicated that silicon and calcium in Coral gravel promoted the growth and photosynthesis, and consequently increased the yield of cherry tomato.
