Custos de implantação e condução de girassol de corte em sistema de plantio orgânico em Laranjeiras do Sul/PR

Abstract

The flower market is constantly expanding in Brazil, demanding more and more quality in the products sold. Thus, there is a need to develop commercial projects that seek to delineate the economic aspects of planting, serving as a basis to indicate what is necessary for the implantation of a crop. The cultivation of sunflower (Helianthus annuus L.) for ornamental purposes is included in the expanding flower categories in the country and its organic cultivation is a possibility of income generation, however there are few studies on its economic aspects. Thus, the objective of this work was to determine the main technical coefficients and costs of implantation and management of 0.5 hectare of ornamental cut sunflower in an organic production system in Laranjeiras do Sul/PR. Thus, the study was divided into three distinct stages. The first was carried out through bibliographical research, aiming to outline the aspects of planting ornamental sunflower in an organic plantation, highlighting its processes and needs. The second stage of the research refers to the installation of an experiment with the objective of validating the proposed study. This experiment was carried out in the 2021/22 agricultural season in the experimental area of the Federal University of Fronteira Sul campus Laranjeiras do Sul. Finally, the third stage refers to the determination of the main technical coefficients and their costs. The summary of the cost results for the implantation and management of 0.5 hectare of sunflower for ornamental cutting in the region of Laranjeiras do Sul were R$: 190,557.40, with the highest expenses related to inputs (97.71%) , followed by mechanized operations (1.31%), manual operations (0.92%) and finally other inputs representing 0.05% of the country. Under the organic planting system conditions in Laranjeiras do Sul/PR for cut sunflower, the total cost for 0.5ha is R$ 190,557.40. The most significant cost components were inputs, which added up to higher values in the process of setting up the experiment.
