Perdas na colheita mecanizada de milho na região de Verê - Paraná

Abstract

Corn (Zea mays L.) is one of the main cereals produced in the world, with Brazil being the world’s largest grain producer. The harvest of this cereal is carried out mechanized by a machine called a grain harvester, which has a track system that can be tangential or radial, axial or hybrid. However, many factors can cause during this process, which in turn can result in significant decreases in profitability. In this sense, this study aimed to evaluate the losses during the Cessation of mechanized corn harvesting in the municipality of Verê - Paraná during the agricultural harvest 2021/2022. Data collection was carried out considering a sample of 11 harvesters. ras, in different properties. During the inspection, parameters related to the machine (year of manufacture, time of use and threshing system), to the operator (age and time of experience) and the crop (grain moisture at harvest, productivity, natural losses and peron the threshing system and on the cutting platform). The data were submitted to an analysis exploratory, through descriptive statistics, with results displayed in the form of graphs. Most harvester operators in the southwest region of Paraná are aged between 21 to 25 years old, with less than 5 years of experience in the activity. The highest loss rates of harvest in the corn crop occurred naturally. Most harvesters belongs to the John Deere® brand, with an axial track system. The age of the harvesters did not influence highlighted the amount of crop losses on the platform. The longer the time of use of a harvester, the greater the losses in the threshing system.
