Applying New Technologies to Transform Blueberry Harvesting

The growth of the blueberry industry in the past three decades has been remarkably robust. However, a labor shortage for hand harvesting, increasingly higher labor costs, and low harvest efficiencies are becoming bottlenecks for sustainable development of the fresh market blueberry production. In this study, we evaluated semi-mechanical harvesting systems consisting of a harvest-aid platform wi...

Catching the rainbow: light harvesting in dye-sensitized solar cells.

effect of variety, time harvesting and fruit size on pomegranate mechanical properties

in this research, the effect of variety, harvesting time and fruit size were investigated on the mechanical properties of skin, density and mechanical strength. the results showed that pomegranate cultivars (ardestani, shisheh-cap and malas) had different skin thickness resulting difference in forces required for penetration of pomegranate fruit (10%). the skin of shisheh-cap variety was thicke...

Comparing of Peanut Harvesting Loss in Mechanical and Manual Methods

The main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. Hence, a field was selected in Astaneh-Ashrafiyeh and divided to three different plots. Two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. According to test results, the lowe...
