Abstract:: The luffa variety ‘Jiangshu No.1’ was used as test material,a field experiment was conducted using completely randomized block design to investigate effect of combined application of nitrogen (N)，phosphorus (P) and potassium (K) fertilizers on chlorophyll content，fruits dry matter content，yield and quality of luffa.The results showed that single luffa dry weight and fresh weight of potassium nitrate∶calcium superphosphate∶potassium sulphate (2∶1∶1.5)T4 treatment were the highest，dry matter content of potassium nitrate∶calcium superphosphate∶potassium sulphate (1∶1∶1.5) T2 treatment was the highest，followed by T4 treatment.T4 treatment had the highest total chlorophyll content，followed by potassium nitrate∶calcium superphosphate∶potassium sulphate(1∶1∶3) T3，compound fertilizer (1 500 g) T7 and T6 treatment.T4 treatment had the highest carotenoid content than other treatments，followed by T6 and T3 treatments.The content of the soluble sugar of T2 treatment was the highest，followed by T4 treatment；the content of the soluble protein of T7 treatment was the highest，followed by T4 treatment.Early yield and total yield of CK were the lowest.Early yield and total yield of T4 treatment were the highest and increased by 18.54% and 28.76% when compared with CK.T4 treatment which could increase yield and quality of luffa was the best on the ratio of fertilization.
