This experiment was conducted to find possible relationship between nitrogen in nutrient and the growth of the clone of the grafted Akamatsu tree.
The trees were planted in pots filled with pure sand and embedded in ground.
Each pot received the factorial combination of 5 levels of N as ammonium sulphate 0, 10, 25, 50 and 100 p.p.m. and 60 p.p.m. of K as K_2O, and 40 p.p.m, of p, Ca and Mg as P_2O_5, CaO and MgO, and 5 p.p.m. of Fe as Fe_2O_3 per trees.
Nutrient solutions were applied to supply 10 liters per pot each week from April to September of 1958 and 1959, And in april of 1960 too.
The effects of concentrations of nitrogen may be summarized as follows :
1. The concentration of N should seem affect the growth more in the number of branches than on the height and the diameter of a tree.
2. The optimum concentration for the growth appeared to be 50 p.p.m..
3. We observed that the number of leaves shall grow in proportion with the size of seedlings and the length of in proportion with the diameter of twigs.
