Abstract:: The effects of different concentrations of liquid humic acid foliar fertilizer on yield and quality of two varieties of beans ‘Zihuayoudou’ and ‘Jiangjunyidianhong’were studied to provide scientific base for applying liquid humic acid foliar fertilizer reasonably in quality vegetables planting by randomized block design with three replications in greenhouse.The results showed that 600 times of dillution was the most effective among all concentrations of liquid humic acid foliar fertilizer.The yield increased significantly in the two kinds of beans，‘Zihuayoudou’ was 11.6%，‘Jiangjunyidianhong’was 9.8%.The quality was improved significantly.The content of soluble sugar，VC and protein content increased significantly.The contents of nitrate in the two varieties of beans was declined in the concentration of 600 times of dillution，‘Zihuayoudou’was 26.3%，‘Jiangjunyidianhong’ was 25.6% respectively.
