Caracterização de manejos das principais culturas agrícolas na área de entorno do Parque Estadual de Vila Velha, Paraná, Brasil

Abstract

ABSTRACT. The objective of this paper is to contribute to the implementation of lessimpacting farming practices in environmentally sensitive areas. Vila Velha State Park is located in Campos Gerais, a region of high-technology agriculture. Typical farming systems in the park's buffer zone were identified in visits, and characterized in consultations with experts, agronomists, retailers and stakeholders. Three major systems (A, B and C) were described, considering the most common practices in crop rotation, choice of products and machinery operations for soybean and corn production. Systems A and B are characterized by high investment and technology level, though System A has more capital for investment. System C is typified by the use of service packages offered by commissioned retailers. Alternatives to mitigate environmental impact could potentially arise in experiments conducted in association with Farmers A and B, and through economic studies with Farmer C.

Performance of the AquaCrop model for the wheat crop in the subtropical zone in Southern Brazil

“…In the state of Paraná, the winter crop is the most important, reaching about 1.081 million hectares of planted area in the 2015/2016 harvest, with a production of 3.3 million tons (Oliveira Neto & Santos, 2017). The Campos Gerais region stands out in the state due to its agricultural potential, which is above the national average (Shimandeiro et al, 2008).…”
