Abstract: Objective] In order to offer theoretic basis for camellia cake utilization ,the effects of camellia cake on the growth of banana and on f usarium wilt control were investigated through a field test .[Meth‐od] Camellia cake was applied as basal fertilizer ,and banana seedlings were inoculated with Fusarium ox‐ysopoyum f. sp. Cubence race 4 (Foc4) 4 months after transplantation .The effects of camellia cake on growth ,fruiting rate and yield of banana and f usarium wilt control of the plant were studied .[Result]Camellia cake played positive roles when applied at the rate of 100kg/mu (15 mu = 1 hectare) .Nine months after the treatment ,the average plant height ,stem girth and the number of green leaves were 198.67 cm ,14.85 cm and 10.27 ,respectively ,while those of CK were 197.00 cm ,14.44 cm and 10.10 , respectively .The fruiting rate and the number of banana fruit of the treatment were 87.88% and 125.00 , respectively ,as compared to 81.67% and 121.25 for CK ,respectively .Without camellia cake top‐dressing after inoculation with banana f usarium wilt , the mortality of banana plants of the treatment with 150 g/m2 as basal fertilizer was 16.67% lower than that of the control .Furthermore ,high dose camellia cake application ,such as 300 g/m2 and 450 g/m2 ,negatively affected banana grow th .[Conclusion] High doses of camellia cake can inhibit the grow th of banana ,reduce the fruiting rate and fruit number ,and de‐lay fruit maturation .Appropriate doses of camellia cake have positive effects on the grow th of banana , help to control f usarium wilt of banana and increase banana yield .
