I had reported the effcct of bark powder of camphor tree on the growth of the crops, and after ward I conducted the same experiments on rice plant, upland rice, barley, wheat and potatoes. The result on the germination and the field experiment on potatoes are as follows. I Germinating cxperiment One section (withont powder) and the other (with powder) Were 100 percent in germination percentage. In the germinating energy, the top was the best and the middie and the base followed in order. In comparing the standard with the other, I could not find any difference between them But the middle and the base buds of the latter were superior to the standard. ll Field experiments I conducted the experiments dividing 3 section. A section (put the powder on cut surface). C section (mixed the powder in the soil) and. B section (without the powder). A and C sections were better than B section in harvest at the rate of from 23-38 percent. ln the beginning there were some tendency of retarding in A and D section, but at the end I found the one with the powder mixed in soil was the best in harvest.
