Results indicated that the pre-harvest fruit losses were lower in early season compared to those harvested later. Un-harvested berries on the plants and losses through the blower were significantly lower than losses on the ground. Significant relationship among the fruit yield and total losses (r = 0.54 to 0.82) suggested that losses during harvesting were proportional to fruit yield. A factorial analysis of variance (ANOVA) showed that ground speed, header rpm, and their interaction were found to have significant (p=0.05) effects 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 a suitable combination of ground speed and header rpm can minimize the fruit losses during harvesting. This can increase harvestable yield and farm profitability.
