<br/><br/> This investigation was carried out in 2000 and 2001 to study the effect of two rootstocks (seedling and Trabols), different rates of nitrogen and potassium fertilizers and their interactions on shoot length, fruit set, fruit retention, yield and leaf mineral content of Costata persimmon trees. The results are summarized as follow: 1. Regardless of potassium fertilization and rootstock. nitrogen fertilization increased shoot length, fruit set, in 2001. Fruit retention, yield and leaf Nand Mg were increased in both seasons. On the other hand, leaf K, Fe and Zn in both seasons and P in the seoond season were decreased. However, leaf Ca and Mn were not affected by nitrogen fertilizer. 2. Regardless of nitrogen fertilization and rootstock, potassium fertilization increased fruit set, fruit retention, yield and leaf K, Zn and Mn, whereas leaf Ca, in both seasons, and Mg, in 2001, were decreased. Shoot length and leaf N, P and Fe, in both seasons, and Mg, in 2001, were not affected by the addition of potassium sulphate.
