Abstract
Objectives: This work was carried out to estimate the optimal plant density for 4 Valencia orange varieties and to determine the highest yield potential as a strategic to overlap the yield reduction by citrus HLB disease. Methodology: Tree growth data of nine years [(height, diameter and canopy volume (CV); area of soil covered by canopy (ASC)] and yield in kg/tree (Y) of four varieties were analyzed first by correlation analysis and then submitted to a lineal and multiple regression analysis. Contribution: Correlation values of 0.8 and 0.85 were observed for ASC and CV with Y, respectively. Based on these variables the optimal calculated tree densities by regression for “Pineapple”, “Queen”, “Cutter” and “Campbell” varieties were 900-1000 trees/ha, which can yield 30 to 60 ton/ha/year, from 4th to 9th year.
