Conteúdo: | The effect of tooping hright and tree removal on yield of over-crowded, non-productive, 34-year-old 'Lula' and 'Booth 8' avocados (Persea americana Miller) was studied. Trees were periodically topped at 9 (subsequently 12), 16, or 22 ft with or without eventual removal of every other tree on a diagonal within the grove. 'Lula'produced no fruit during the first three seasons after topping. During the fourth season, 'Lula' topped at 16 and 22 ft with trees removed had more fruit per tree (1.6 and 2.2 bu/tree, respectively) than other topping teatments. 'Lula' trees topped to 22 ft with and without trees removed produced more fruit per acre (119 and 108 bu, respectively) than trees topped at 9 ft (43 bu/acre) and 16 ft with trees removed (86 bu/acre). 'Booth 8'topped at 22 ft with no trees removed and 16 and 22 ft with trees removed produced fruit during the second season after topping. More fruit was produced in 'Booth 8' plots topped to 16 and 22 ftwith trees removed(469 and 464 bu/acre, respectively for two years combined) than those topped to 9 ft with trees removed and 22 ft with no trees removed (130 and 249 bu/acre, respectively for two years combined) Topping at 16 and 22 ft with tree removal increased the percentage of fruit in the lower third of 'Lula' and 'Booth 8' canopies, whereas more fruit was produced in the middle of the canopy for trees topped at 22 ft without tree removal.
