Influence of seed physical properties and speed on the external mechanical damage index and in-row spacing uniformity in an automatic potato planter

Bu çalışmada, dikey bir disk etrafına belirli aralıklarla dizilmiş kepçe ve tutucu çubuklardan oluşan tohum dağıtma düzenine sahip yeni bir tam otomatik patates dikim makinası kullanıldı. Tohum dağıtma düzeninin performansını değerlendirmek için sıra üzeri tohum dağılım düzgünlüğü ve yumru zedelenme indeksi belirlendi. Ayrıca sıra üzeri dağılım düzgünlüğünün bozulmasına sebep olan boşluk ve ikizlenme incelendi. Denemelerde iki farklı patates çeşidi (Marfona and Agria) ve iki farklı patates boyutu (25-45 ve 45-65 mm) kullanıldı. Patates dikim makinası ilerleme hızları 3.5, 5.4 ve 7.3 km h-1 olarak seçildi. Yumru fiziksel özelliklerinin ve makina ilerleme hızının sıra üzeri tohum dağılım düzgünlüğünü ve zedelenme indeksini önemli derecede etkilediği belirlendi (P

Tam otomatik bir patates dikim makinasında tohum fiziksel özelliklerinin ve makina ilerleme hızının sıra üzeri tohum dağılım düzgünlüğü ve yumru zedelenme indeksi üzerine etkisi

In this study, a new fully automatic potato planter was used in which the planting metering mechanism consists of cups and hold pins attached to the circumference of a vertical disc. In order to evaluate performance of the planting metering mechanism, in-row spacing uniformity and external mechanical damage index were determined (P
