Abstract
The effects of 0.1% and 0.5% chitosan application on the shoot growth of rice and soybeans were investigated after incorporating it into soil before planting. In non-fertilized soil, plant heights, leaf numbers and SPAD values of rice increased, but in fertilized soil they did not increase by chitosan application. At an early stage, the growth of soybean was improved by the application, but later it became almost similar in applied and control plants. Differing from rice, the growth of soybean did not vary by chitosan application under fertilization. The effects of chitosan application on shoot growth improvement were considered to be different by crop.
