Paclobutrazol applied to the soil is used for the production management of mango in most of orchards on the semiarid region. However, it is necessary to identify other plant growth regulators that might be applied to the leaves, so as to minimize the risk of residues in the soil and plant. The present paper has the purpose to evaluate the effect of plant regulators in the management of vegetative growth on mangoes Tommy Atkins. Three plant growth regulators, sprayed to the leaves, were evaluated: prohexadione-Ca, ethyl-trinexapac and chlormequat chloride, applied in two dosages, and compared to paclobutrazol applied to the soil. In order to compare the effects of the treatment, data were recorded on the vegetative growth (number and length of the shoots). Furthermore, the levels of gibberellins in the apical area of the shoots of Tommy Atkins were quantified, from the beginning of the experiment until the beginning of floral induction. The results showed that sprayings with prohexadione-Ca, trinexapac-ethyl and chlormequat chloride in a dosage of 1.5 g a.i. plant-1 plant was as efficient as a dose of 4.0 g a.i. plant-1 of paclobutrazol applied to the soil, regarding the regulation of vegetative growth of Tommy Atkins. |

Meeting the future food needs of the world can be accomplished by increasing productivity in traditional areas and by occupation of new areas not yet cultivated. Tropical regions present both alternatives, but agricultural expansion seems more important, as 830 million hectares of potentially arable land are available. Shifting cultivation and cattle grazing are the most traditional activities and the present food production is scarcely sufficient for the native population. The tropical area is mostly covered by rainforests and savanna vegetation. The climate is hot and total rainfall is high; however, rainfall distribution constitutes a problem in some parts of the tropics. The predominant soils, Oxisols and Ultisols, are commonly deep, well drained and well structured, but they are highly acid and very low in nutrients, especially phosphorus. To solve or minimize these problems, any soil management scheme should aim at: (1) improving the natura low soil nutrient status and neutralize part of the soil acidity; (2) minimizing the risks related to dry spells; and (3) protecting the soil against erosion, since rainfall intensity is usually high during the cropping season. Once these goals are accomplished by soil management, over 800 million hectares can be put to use for intensive cultivation with annual and perennial crops and for cattle grazing. It is estimated that rational utilisation can result in more than enough food production to meet the needs of 2 billion people or more within 20 to 40 year.
