1) These studies were conducted with the view to obtain more detail data of nitrogen application of peanut growing. Java No. 13 was sown at 20th. Apr., May and Jun. respectively in 1959,Java No. 13 and Chibahandachi were at 20th. May in 1960. In the both years, each two plots were treated with nitrogen application (control plot) and non-nitrogen application (-N plot). 2) There were no defferences between cotyledon of control plot and -N plot in regard to dry weight, N% and N amount. In the early stage, the distinctive defferences were found upon dry weight, N% and N amount of stem and leaves between each two plots. These effects of nitrogen application on stem and leaves at the early growing stage were closly related with increasing process of the flowering. And this relation was invariable with sowing periods and years. 3) Through the all studies, the nitrogen application had always better yield.
