Effects of Frequency of Nitrogen Application on Yield and Quality of Smooth Cayenne Pineapple
Ananas comosusr cv.Cayenne under 400 kg/hm2 nitrogen application was studied.The fertilization frequency was from 0 to 4 in order to analyze the effects of frequency of fertilizer application on the yield and quality of pineapple.The results showed that average application in two times was the most appropriate treatment to increase the yield of smooth Cayenne.Based on it,less or more than 2 fertilizer application times would result in a decline in fruit weight and yield.With the quality of smooth Cayanne,increasing the frequency of fertilizer application would result in a decline in titratable acid,sugar content and vitamin C.So increasing the frequency of fertilizer application was not conducive to maintaining the quality of smooth Cayenne.The study provided a reference for farmers engaged in Cayenne varieties cultivated fertilization.
