This study was completed with the aim of determining labor requirements, work efficiencies, and total costs of 6 different traditional hazelnut pick-up methods, along with 3 different mechanical harvest methods using a portable-type pneumatic hazelnut harvesting machine, on flat ground in two hazelnut orchards with linear and brush planting systems. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2016) 40: 301-310 © TÜBİTAK doi: Labor requirements and work efficiencies of hazelnut harvesting using traditional and mechanical pick-up methods Taner YILDIZ* Agricultural Machinery Program, Samsun Vocational School, Ondokuz Mayıs University, İlkadım, Samsun, Turkey Received: Accepted/Published Online: Final Version: Abstract: This study was completed with the aim of determining labor requirements, work efficiencies, and total costs of 6 different traditional hazelnut pick-up methods, along with 3 different mechanical harvest methods using a portable-type pneumatic hazelnut harvesting machine, on flat ground in two hazelnut orchards with linear and brush planting systems. Trials were conducted in the two different orchards in the August 2013 harvesting season. Among traditional pick-up methods, the lowest unit of human labor requirements (units of human labor power, h ha–1) in an orchard with a linear planting system was obtained ( h ha–1) for the method involving Ethrel administration, hand-shaking, and rows gathered by garden rake (first method). For the brush-planting system orchard, the lowest value ( h ha–1) was obtained with the method with no Ethrel administration, hand-shaking, and rows gathered by scrub rake (fourth method). In terms of work efficiencies, the best values were obtained ( ha h–1) for the first method for the linear system and for the third method for the brush system ( ha h–1). In terms of time utilization coefficient, the different pick-up methods with the hazelnut harvesting machine obtained lower levels compared to the different traditional hazelnut pick-up methods. In trials of different methods of traditional pick-up, the lowest value for total harvest costs was obtained for the method with Ethrel administered and rows gathered by .
