Abstract：Under the condition of long-term and fixed position nitrogen application in vegetable field, the variations of biomass, economic output and economic coefFicient of different type of vegetables were checked.The relationship between the variations and soil fertility were investigated.Models for output variations were estableshed in the experimental situation. Effect of the coordinated application of organic manure and nitrogen fertilizer on yield was remarkable. Based on the yield respose to fertilizing, vege...
