Studies on Nutrition of Pineapple Iii. Effect of Varying Levels of Npk on Leaf Nutrient Status in Var. Kew in High Fertility Soil

A field trial conducted to determine the response of pineapple (var. Kew) to NPK application in a 3³ confounded factorial design in a soil of high fertility status was utilised for the study of the relationship between NPK application and leaf nutrient contents at various stages of growth. The analysis were done at 5th, 8th and 11th month after planting. In the 5th and 8th months, application of N, P and K was not clearly reflected in the leaf nutrient contents. In the 11th month sampling however, there were significant increases in leaf N, P and K corresponding to N, P and K applications.
