| The largest losses in mechanical harvesting of peanuts occur during the stage of digging, and its assessment is still incipient in Brazil. Therefore, the aim of this study was to evaluate the quantitative losses and the performance of the tractor-digger-inverter, according to soil water content and plant populations. The experiment was conducted in a completely randomized block design with a factorial scheme 2 x 3, in which the treatments consisted of two soil, water content (19.3 and 24.8%) and three populations of plants (86,111, 127,603 and 141,144 plants ha-1), with four replications. The quantitative digging losses and the set mechanized performance were evaluated. The largest amount of visible and total losses was found in the population of 141.144... |

| A colheita mecanizada de cana-de-açúcar é uma tendência crescente e irreversível ao setor canavieiro, devido à sua maior operacionalidade durante os turnos diurno e noturno, em razão das leis ambientais e trabalhistas ligadas a esta operação. Entretanto, o grande desafio deste sistema é a melhoria do mecanismo de corte de base, uma vez que esse mecanismo é capaz de causar elevados índices de danos e abalos nas soqueiras quando associado ao desgaste das facas do mecanismo de corte basal. Diante do exposto, objetivou-se, neste trabalho, avaliar a qualidade do corte basal por meio dos índices de danos e abalos causados às soqueiras, bem como o desgaste de três modelos de facas do mecanismo de corte basal de cana-de-açúcar, em função do tempo de uso.

| ABSTRACT The mechanized sugarcane harvesting process is considered one of the major economic bottlenecks, with low operational efficiency and, mainly, high losses of stalks left in the field. In order to minimize these problems and assist in the improvement of processes, this study aimed to evaluate the losses in the mechanized sugarcane harvesting using statistical process control. The experimental design was completely randomized, based on the methodology of statistical process control with samples collected on five work fronts during the daytime and nighttime operation. The experiment was carried out in an agricultural area of a sugarcane mill in the municipality of Ribeirão Preto, SP, Brazil, on five sugarcane harvest fronts. Losses were measured using... |
