Características vegetativas e produtivas de Pessegueiro Cultivar Eragil em diferentes sistemas de condução na Região Oeste de Santa Catarina, Brasil

Abstract

The implantation of orchards of fruit crops species in southern Brazil is traditionally cultivated in low density of planting and with ‘Open Vase’ training and pruning system. The increase in planting density has been used and tested in different fruit crop species, among which is the peach-tree. The aim of this study is to evaluate the vigor, production and quality of peach-tree cv. Eragil in different training and pruning systems, under the edaphoclimatic conditions at the mid-western of Santa Catarina, Brazil. The avaliations were carried out in two crop years (2015 and 2016). Were used three training and pruning systems: ‘Open Vase’ (5m X 3,5m, 571 trees ha-1), 'Y' (5m X 1,5m, 1.333 trees ha-1) and 'Central Leader' (5m X 0,8m, 2.500 trees ha-1). Were evaluated phenology, vegetative growth (vigor) and the productivity. The plants with ‘Open Vase’ training and pruning system had greater vigor and yield per plant, however, they had lower productivity per area. The plants 'Central Leader' training and pruning system had higher productivity and productive efficiency. The plants with 'Y' training and pruning system were intermediates between ‘Open Vase’ and 'Central Leader' in relation of the evaluated variables. The plants with 'Central Leader' training and pruning system had better performance under edaphoclimatic conditions at the mid-western of Santa Catarina.
