The experiment on N. P and K requirements for pineapple growing were conducted duing the periods of 1955 to 1957 at Chiayi and Fengshan and 1960 to 1961 at Changhua.
The results of the experients have summerized as follows:
(1) Effects on the yield of pineapple fruits
Nitrogen has significant effect on the yield of the fruit in generall, The yield of the fruit has been increased as much as 32~140% at changhua and Fengshan where Nitragen seems to have more significant effect.
Potassium and Phosphorous have no significant effects in increasing the yield of the fruit.
(2) Effects on quality of the fruits
The application of Nitrogen has increased the contents of reducing sugar and total sugar in the fruit as well as promoted the color of the flesh.
Nitrogen seems to reduce the acidity of the juice and improve the taste of the flesh.
Potassium application tends to increase the content of total sugar in the fruit but the application of phosphorous lose flavor of the flesh.
It has been considered that the application of proper amounts of N and K is needed for improving quality of pineapple fruit.
