Abstract:
The objective of this work was to evaluate the effect of pruning and training system type on the agronomic performance of the perennial cultivation of physalis (Physalis peruviana), in high-altitude tropical and humid temperate regions in Southeastern Brazil. The experiments were carried out in the municipalities of Diamantina (humid temperate climate) and Couto de Magalhães de Minas (high-altitude tropical climate), both in the state of Minas Gerais, in two cycles (2017/2018 and 2018/2019). In the first cycle, two types of training system were evaluated, one with formation pruning to define the number of stems for espalier training and the other free (without pruning and espalier). In the second cycle, renewal pruning was evaluated in each training system. Physalis cultivation in regions with humid temperate climate and mild temperatures favors high yields and large fruits. The training system in espalier with formation pruning facilitates plant management and increases productivity. The viability of the perennial cultivation of physalis varies according to the climatic conditions of the cultivation site and to the training system adopted.
