USE OF PACLOBUTRAZOL IN MANGO ORCHARD IN SOUTHWEST REGION, BAHIA STATE, BRAZIL
The present work was carried out in the Southwest Region of Bahia State, Brazil, in mango orchards from November, 1997 to November, 1998. The purpose of the study was to identify the percent of mango orchards using paclobutrazol (PBZ) and the results obtained in relation to flowering and production. About ten percent of the total area with mango cultivation of the region was evaluated. The percentage of orchards that used PBZ, concentration and month of application, was determined in relation to flowering (after spraying with potassium or calcium nitrate) and production. The results were concluded as: a) 63% of the orchards from three to more years used PBZ, from 0.5 to 1.0 g a.i. per meter of canopy in diameter, from November to December, 1997; b) 100% of the orchards were sprayed with potassium or calcium nitrate, after 90 to 120 days after PBZ application to induce flower initiation; c) trees that received PBZ produced flowering and yield earlier than those received only nitrate sprays; d) orchards with PBZ can harvest from June, July and August 1998, while those sprayed with only nitrates can harvest from August, September and October, 1998.
