Effects of different fertilization treatments on meat luffa yield and fertilizer use

In order to better understand the effects of fertilizer on meat luffa, different nitrogen, phosphorus and potassium fertilizer and organic fertilizer experiments were carried out in Jiangmen. The results showed that, the effects of nitrogen fertilizer on meat luffa were the greatest maximum, increasing organic fertilizer could improve the early yield and total yield, the fertilizer agronomic efficiency, partial factor productivity and utilization rate were better in the low level. Through regression analysis, the equation of fertilizer effect was obtained, and the optimum amount of fertilizer was calculated. To obtain high yield and high efficiency, in Jiangmen area, the recommended amount of commercial organic fertilizer per 667 m2 250 kg, the optimum amount, of nitrogen, phosphorus and potassium were as follows: N 23 kg, P2O5 11 kg, K2O 17 kg.
