Estudo da época de poda hibernal e irrigação na produção antecipada de pêssegos.

Abstract

It was aimed in this study to evaluate the influence of irrigation and different hibernal pruning dates in the phenology of peach tree, cv. Diamante, as well as to verify its reflexes on the production. The experiment was carried out in a 4-year- commercial orchard, conducted in “Y” system, spaced 4 x 2 m, in the municipality of Lavras, MG, during the 2003/2004 and 2004/2005 season. It was studied the following pruning dates: 05/01, 05/15, 06/01, 06/15. Experimental design was random blocks, with 8 treatments and 3 repetitions in a 4 x 2 factorial outline (four pruning dates with and without irrigation), being each plot composed of four plants. It can be concluded that the best results were obtained with prunings in 05/15 (no irrigation) and 06/01 (with irrigation), allowing to anticipate harvesting in 31 to 37 days, giving a relatively high production (14,17 kg/plant with no irrigation and 14,33 kg/plant with irrigation, respectively). The use of irrigation made possible to obtain bigger fruits (108,91g), independently of the pruning date.
