Phenological Characterization and Productivity of the Physalis peruviana L., Cultivated in Greenhouse

Abstract

The Physalis peruviana L. presents great nutritional value and economic viability, becoming an alternative for the small and medium producer and an innovation for the Brazilian horticulture. However, some information on cultivation, are still scarce. In this context, our objective is to characterizing the phenological phases and productivity of the Physalis peruviana cultivated in a greenhouse in the semiárido paraibano. This work was done in the experimental farm of the Federal University of Campina Grande, campus Pombal, Paraíba. The experiment was driven in a randomized blocks design, with five repetitions, each repetition constituted of five plants. The phenological phases were determined through the height, diameter of the stem, number of leaves, floral buttons, flowers and fruits per plant, production and productivity. The data were submitted to the variance analysis and polynomial regression. The vegetative phase of the Physalis peruviana L. is concluded in a period understood among 32 to 45 days after the transplant (DAT) and the reproductive phase extends until 161 DAT. In the conditions of the semiarid, the crop of the fruits of the Physalis peruviana L. begins to 71 DAT, with a dear productivity of approximately 2 340.95 kg ha-1.
