Perdas na colheita mecanizada do milho

Abstract

Corn (Zea mays) is one of the main agricultural crops in Brazil and in the world, having a very important role due to its ability to adapt to adverse climatic and soil conditions, besides being one of the main grains used in human consumption animal. Losses occur throughout the entire maize production chain, causing losses to farmers. Losses during mechanized harvesting may have significant value in reducing the net crop revenue. In view of this problem, this work aims to determine the losses that occur in the internal mechanisms of the harvester in the corn harvest. For evaluation, four different velocities of displacement were used, as well as two sizes of collection places to evaluate the losses. In order to evaluate the losses, a completely randomized design (DIC) was used, in a 4x2 factorial scheme using 4 displacement speeds (3km / h, 4km / h, 5km / h and 6km / h) and two collection places 2m² and 4m². It was concluded that the losses increased in the displacement velocity and there was no significant difference between the area sizes used for data collection.
