Abstract

Abstract: The objective of this work was to elaborate the agricultural zoning of climatic risk (ZARC) for Physalis peruviana, through the thermal and water requirements of the crop in Southeastern Brazil. Air temperature (TAIR) and precipitation (PYEAR) data from 1,530 meteorological stations covering the entire region were used. Regions were considered climatically favorable to Physalis peruviana when TAIR was between 13 and 18ºC and PYEAR between 1,000 and 2,000 mm per year. Regions where TAIR was above 30ºC or less than 13ºC were considered inapt. Maps were created with this information and used to identify climatic characteristics and to establish the agricultural aptitude classes, termed apt, inapt, and marginal for the cultivation of Physalis peruviana. The Southeastern region of Brazil showed a thermal variation from 16.5 to 22.6°C and water amplitude from 800 to 2,800 mm. ZARC shows that 10% of Southeastern Brazil is climatically apt for the cultivation of Physalis peruviana, corresponding to the following regions of Brazilian states: central and southern Minas Gerais, western Rio de Janeiro and Espírito Santo, and eastern and southern São Paulo.

Highlights

Physalis (Physalis peruviana) is a non-native species that has been increasingly cultivated in Brazil (Palomino et al, 2011)
The highest TAIR occurred in the area of Triângulo Mineiro that consists of parts of the northeast of the state of São Paulo, the north of the state of Minas Gerais, and the east of the state of Espírito Santo, with values above 22.6oC
The lowest TAIR are concentrated in the south of the state of Minas Gerais, where values below 16.5oC were recorded (Figure 3 A)

Summary

Introduction

Physalis (Physalis peruviana) is a non-native species that has been increasingly cultivated in Brazil (Palomino et al, 2011). The ideal temperature for physalis cultivation ranges between 13 and 18°C, and this species is productive up to 30°C (Salazar et al, 2008a; Fischer et al, 2014); above this temperature, flowering and, fruit production, are subject to severe reductions. The ideal hydrologic regime for cultivation of physalis is between 1,000 to 2,000 mm, with equal distribution throughout the year, and air relative humidity to prevent fruit deterioration should be between 70 and 80% (Fischer, 2000; Rufato et al, 2008). Precipitation values above this range stimulate excess vegetative growth, and increase the incidence of diseases
