Abstract


An experiment was conducted in a private orchard, located along the Blue Nile bank at Hantoub, Gezira State during the seasons of 2007 and 2008, to investigate the effect of improved harvesting methods on reducing physical injury during harvesting of mango fruits of selected cultivars viz. Kitchener (Baladi), Alphonso, Timour, Abu Samaka and Gulbeltour. The experimental design was a split plot with three replications. Cultivars were assigned to the main plots and harvesting methods to the subplots. The harvesting methods consisted of a ladder, a modified picking pole (MPP), a straw mattress (SM) and the traditional picking pole (control). The ladder harvesting method resulted in the lowest percentage (4.4%) of physical injury followed by the modified picking pole (16.0%) and the straw mattress (29.5%), while the traditional picking pole resulted in the highest percentage (53.1%) of physical injury. The cultivar Gulbeltour and Abu Samaka showed the highest percentage of physical injury, while Timour showed the lowest. Both the ladder and the modified picking pole harvesting methods took the longest time (44 minutes) to harvest one hundred mango fruits followed by the straw mattress (19 minutes) and then the traditional method (10 minutes). The cultivars Alphonse, Kitchener and Timour required less time to harvest one hundred fruits, while Gulbeltour and Abu Samaka required more time.
