INFLUENCE OF UREA ON THE CHANGE OF SOIL pH AND SEEDLING HEIGHT OF RICE (Pages : 46 - 49)

The experiment was conducted to observe the effect of urea on the changes of pH in the soil and growth of rice (BRRI Dhan-27). Urea (80 kg ha-1) was applied to one of the seedlings after 20 days of germination and the soil pH and length of rice were determined after 25 days of urea application. Soil pH was gradually decreased with increase rice grown in the control seedling. However, no changes of pH were found in the urea treated seedling up to 20 days of germination and were similar to the control. The pH of soil compared to the control falls gradually with increase rice growth. Seedling height was gradually increased in both the control and urea treated seedlings from the germination. However, higher length was found in the urea treated seedling. Up to 20 days of germination of rice, no differences of seedling height in the two seedlings were observed. This findings suggests that urea is the potent compound inducing growth of rice and pH measurements indicate the period where optimum uptake of urea is happened.Download
