'Manila' mango is the most important cultivar grown in México.
Trees reach up to 30 m in height limiting plant density to only 50 trees ha-1. This increases the cost of phytosanitary protection and harvest.
The objective of this research was to reduce 'Manila' (M) tree height using diverse combinations of interstock-rootstock.
Cultivars used were: 'Esmeralda' (E), 'Irwin' (I), 'Diplomático' (D), and 'Thomas' (T). Results showed that, at 9 years of age, combinations like M/T/E and M/I/I reduced both tree height and canopy diameter by 51% and 40%, compared to 'Manila' seedling trees.
Accumulated 5 years production in these combinations was 99 and 96 kg tree-1, respectively.
Production efficiency, expressed as yield per stem cross sectional area was 0.647 and 0.612 kg cm-2; whereas yield per canopy projection area was 4.4 and 5.8 kg m-2, respectively.
These means are 161% and 216% higher in efficiency than 'Manila' seedling trees.
These improved combinations could allow planting densities of up to 500 tree ha-1.
