Agricultural zoning of climate risk of banana tree (Musa sp) in the hydrographic basin of paraná river 3, brazil

Abstract

Fruticulture is a prominent segment of Brazilian agriculture. Agroclimatic zoning should be one of the first information to consider when starting a particular crop. Thus, the objective of this work was to perform climate risk zoning for Banana (musa sp) in the basin of Paraná River 3, Paraná state, South of Brazil. We used meteorological data from 43 stations from 1976-2018. The climate risk analysis was based on the climatic requirements of the species, such as rainfall, annual water deficit, average annual and coldest month temperature and the risk of frost. The findings of this study suggest that the basin has areas with low climate risk for banana crops. Rainfall precipitations and water balance were sufficient in all scenarios tested. Only in particular periods during the summer in specific locations was a water deficit registered, however that does not restrict production. The most limiting factor for production in part of the basin is the occurrence of frost, thus restricting production in the eastern portion of the basin. In the far west the low altitudes often provide high maximum temperatures and management techniques should be used in extreme heat.
