MARTINEZ VARONA, Roberto. Controlled deficit irrigation effect in the productivity of the banana tree. Rev Cie Téc Agr [online]. 2013, vol.22, n.2, pp.51-55. ISSN 2071-0054.

Banana is a species highly sensitive to water stress, so it is not expected to respond positively to the lack of soil moisture soil at any developing stage. However the lack of rain that has characterized the country in recent years, advises determine which phases occur most affected, with the aim of establishing effective irrigation strategies in times of low water availability. To this end, this research was conducted, using the same witness that was irrigated throughout the growing season and four treatments in which irrigation was suspended several months for which transited their respective cycles. The results indicate that the most affected phase, where there should be no water stress were; the planting ranging from up to 50% bloom and ranging from 90% until the end of flowering of the crop, both affectation values above 20% productivity. Proved to be the least affected between 50 to 90% of blooming, where the productivity is only affected by less than 15%.

Keywords : banana; controlled deficit irrigation; productivity.
