Abstract
Field trials were conducted to determine the optimum nitrogen (N) in combinations of foliar and soil application and the concentrations of urea for foliar application in pineapple. No increase in fruit weight and yield was observed in either the plant crop or the ratoon crop with foliar application of urea compared to soil application. This lack of yield response from foliar application was further substantiated by leaf N status. Leaf N content was found to be significantly different in the “D” leaf but not in the base leaf. Under the conditions of the trial, where fertilizer N was applied in split doses, soil application seemed to be as good as foliar application.
