Abstract
The results of the experiment showed that combined application of K, N obviously promoted tomato growth. The fresh weight, dry weight, stem width and leaf area per plant increased with the increasing of K concentration in nutrient solution and showed significant positive correlation. Blooming, fruit-setting and cropping date were advanced with increasing of concentration of K and N.
