Desempenho operacional e danos na soqueira da cana-de-açúcar submetida a dois sistemas de colheita

Abstract

The use of the Policana device for crop of sugar cane generates an increase in the volume of sugar cane processed by the machine per unit time, increasing the capacity of the harvester. Aimed to evaluate operational performance and damage to the ratoon of two systems to harvest sugar cane, the first self- propelled harvester and the second formed by self-propelled harvester with Policana 2L device. The field tests were performed at the Agricultural Company New American commercial area, located in the city of Caarapó - MS. The variety harvested was SP83 - 2847, without burning, fourth cut, with spacing of 1.4 m. To evaluate the operational performance, losses and damages to the ratoon, was performed analysis of the confidence interval using the t test at 5 % probability. The harvest done using normal harvest with the Harvester and Policana 2L device provided higher field capacities and capabilities of handling and lower fuel consumption per area, while remained similar fuel consumption per ton of cane harvested, yield operating efficiency and handling. Crop losses of cane sugar and the damage caused to the ratoon plant remained similar between the two harvesting systems studied. The use of Policana 2L device coupled to the harvester during harvesting of sugarcane was able to deliver 14.7% increase in the capabilities of the machine work.
