Comparison of Three Planting Distances and Fertilizer Applications on the Yield of Pineapple VarietyPR 1-67

Abstract

An experiment was established at Manatí, Puerto Rico, on a Bayamón fine sandy loam to determine the inf1uence of three different planting distances and fertilizer applications on yield of the new pineapple variety PR 1-67. The three distances compared in the experiment varied only along the lines of double rows and consisted of intervals of 12, 18 and 24 in, equivalent to 13,403, 8,944 and 6.701 plants per acre, respectively. Fertilizer applications were 1.5075 ton/acre for the 12-in spacing, 1.006 ton/acre for the 18-in spacing and 0.7545 ton/acre for the 24-in planting distance in the first crop; and .4188, .2795, and .2094 ton/acre, respectively, for the second crop. The best planting distance and fertilizer application for the plant crop was 24 in between rows and 12 in within the row with 1.5075 tons/acre of 13-3-12 fertilizer.
