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

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 semiarido paraibano. This work was done in the experimental farm of the Federal University of Campina Grande, campus Pombal, Paraiba. 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.

Physiological behavior of melon cultivars submitted to soil salinity1

Melon has a great economic value in the Brazilian market, being one of the crops with the highest growth rate for vegetables exported by the country. In 2016, Brazil ranked 12th in the world production scale, being the largest melon producer in South America, with a national average yield of 25,814 kg ha-1 (FAO 2017, IBGE 2017). Besides the economic and food influence, Brazil also has a great social relevance in the generation of direct and indirect jobs in the Northeast of the country, the ABSTRACT RESUMO
