Abstract

The objective of this study was to evaluate different pistachio hullers and determine the proper harvest time of pistachio nuts for hulling. Three pistachio hulling machines (Helical drum, Helical- blade drum, Rubber drum) at three harvest times and 15 days interval were evaluated. The hulling efficiency, percentage of damaged nuts, faulty hulled nuts and unhulled nuts were measured at each time interval. A factorial experiment was carried out using a randomized complete block design with three replicates. Data were compared using analyses of variance and employing Duncan's multiple range test. The results showed that the interaction effect of hulling machine type and harvesting time on the hulling efficiency and nut damage in the outlet of hull and nut was significant at the five percent level (p
