AbstractInvestigation of the number of fertilizer applications needed for optimum yields of Red Spanish pineapple on a Bayamón silty clay at Bajadero, Arecibo showed that: 1. One application at time of planting was equal to, or better than, splitting the same quantities of fertilizer into two or three applications. 2. The total fertilizer applied was more important than number of applications made. A discussion is presented in which the credit for the lesser number of fertilizer applications is given to the increased vigor of the pineapple plant when kept free from disease and insect attack.
