Effects of organic fertilizer (compost) and/or humic acid as a stimulators on minimizing mineral nutrition rate were evaluated in order to decreasing the environmental pollution and high cost of banana production. Field experiments were carried out during two growing seasons (2014/2015and2015/2016) at wadi El-Natrun, Nubaria region, El-Behera Governorate, Egypt on Grand Naine cultivar grown in sandy soil and the irrigation was pumped from a well fresh water (1.18 dSm^-1). The data indicated that application of compost with or without humic acid minimizing the recommended values of mineral fertilization used for banana production to about 50% without affecting on its productivity. Using 50 ton compost with spraying banana plant (Grand Naine cv) three times on the middle of April, May and June by humic acidat 1500 ppm gave best results with regard to growth, flowering and maturity as well as productivity. These recommended treatments stimulated all studied growth parameters as well as recorded earliness flowering and maturity. In addition it increased, bunch weight and total yield as well as improved physical and chemical characters of the fruits in relative to the control.
