Determination of the Application Parameters of Spraying Drones for Crop Production in Hazelnut Orchards

Hazelnut, which has the most common cultivation area after almonds and walnuts among shell fruits in world, contains high levels of fat, protein, carbohydrates, various minerals vitamins. Hazelnut a broad growing around Turkey accounts for 58% world production with 776,000 tons annually. With this capacity, ranks first hazelnut over world. Harmful insects trees are main factors that reduce yield quality. Pesticides sprayed backpack sprayers fight against these pests trees. Farmers directly exposed to pesticides practices, use amounts water. In recent years, unmanned agricultural vehicles agriculture increased. Drones also used pesticide applications agriculture. study, suitability drone fields Giresun province terms field conditions spraying efficiency was investigated. September 2021, were made DJI Agras MG-1P model selected orchard Uzgur village province. The 4 Teejet XR11001VS fan jet nozzles. Water-sensitive papers placed on different regions be drop measurements. experiments, using water at heights rates. 6 flights carried out 1.5 2 meters altitudes 1, 3 L.da-1 spray rates, three hazel as repetitions each flight. After flight trials, water-sensitive scanned scanner, volume median diameters number droplets per square centimetre calculated DepositScan software. As result analyses done, it observed performed 1 rates would not sufficient efficiency. altitude increased, accumulation drops inner leaves decreased. distribution, homogeneous application parameter found above upper rate.
