Manual and mechanical harvesting were compared by the number of pistachio shell trees harvested per hour (hours / tree). Harvest time of one kilogram of pistachios (min / kg), harvest time by one person to harvest one kilogram of pistachios (min / kg-person). The results are shown in the table below.
To compare the apparent yield of one tree (fresh fruit) and the number of trees per hectare, it was assumed to be 30-25 kg per tree and 100 trees per hectare. The highest harvest was obtained by mechanical harvesting. The average time required to harvest a tree was 4.82 minutes. It takes 1.56 minutes for mechanical harvesting of one kilogram of pistachios by the labor force.
