The Effect of Different Combinations of Nitrogen,Phosphorus and Potassium Fertilizer on Yield of Pepper

The application model between application norm and yield was established through the 3414 experimental design of fertilizer efficiency in pepper.The results showed that nitrogen fertilizer was the main factor to affecting pepper yield and the order of affecting pepper yield was nitrogen potassiumphosphorus.The suitable application combination is 7.65～8.78 kg/667m2 of pure nitrogen,1.46～4.23 kg/667m2 of pure phosphorus and 7.12～9.04 kg/667m2 of pure potassium for high pepper yield planted in the soil with middle fertility in Suiyang county.
