In order to investigate the occurrence status of tiller at the upper node of rice, this trial was conducted with different eco-types and 23 cultivars in 1983 and testified the effect of fertilizer levels with Indica x Japonica cultivars in 1984. In occurring of tiller at the upper nodes, upper 2nd node and 3rd and lower 2nd node and 3rd rose simultaneously. The tillering rates of the upper nodes of Japonica x Indica cultivars were more than Japonica cultivars and early maturing cultivars were more than medium or late maturing cultivars, respectively. Highly negative correlations were found between the tillering rate of upper nodes and days from transplanting to heading and bending angle degree of 2nd node. The tillering rate of the upper nodes treated with different levels of fertilizer increased with non-fertilizer than those of standard (N-P-K = 15-11-13Kg/10a) or heavy (N-P-K = 25-15-18Kg/10a) levels.
