Abstract
A water culture was conducted with 5 levels of nitrate-ammonium ratio (NAR: 10:0, 7:3, 5:5, 3:7, 0:10) to study the ionic balance, cation-anion (C-A) in mulberry leaves and to determine the optimum NAR for the greatest leaf yields. The results were as follows: 1. The growth rate of mulberry plants was the greatest at 7:3 NAR. 2. Magesium in the mulberry leaves was not affected by NAR. By lowering NAR, calcium content decreased more than potassium content increased, consequently lowering the sum of cation content (
