Keywords: Harvesting efficiency fruit losses mechanical harvester head revolutions and wild blueberry.
The results of classical statistics suggested that the pre-harvest fruit losses were lower in early season of harvesting. Un-harvested berries on the plants and losses through blower were significantly lower than losses on the ground for selected fields. Significant relationship between the fruit yield and total losses suggested that losses during harvesting were linear function of fruit yield within selected fields. Factorial analysis of variance (ANOVA) showed that ground speed, header rpm and their interaction were found to have significant impact on the picking efficiency of the harvester. Results of means comparison showed that a combination of 1.2 km h-1 and 26 rpm resulted in significantly lower losses when compared with other treatment combinations. Results also revealed that an ideal combination of ground speed and header rpm can minimize the fruit losses during harvesting, which will increase harvestable yield and ultimately enhance farm profitability.
