A DEVELOPED POTATO PLANTER FOR MINIMIZING POTATO TUBER MOTH AND GREENING [PDF]

Misr Journal of Agricultural Engineering, 2011
The maximum prevention control for both moth to reach tubers and exposure tubers to lightmechanically through the constructed shape of the potato hill by each potato planter was the main aim of this study. For this purpose the performance of a modified potato planter, equipped with designed bedding unit (Batana) was investigated.
