Study of the Effect of Potato Lifter Line on Some Properties at Different Depths and Varieties of Potato Crop

Abstract This research aims to study the effect of number harvest rows under two digging depths and cultivars on quality harvesting potatoes (damage losses). The experiment was factorial, using a randomised complete block design with split-split plot three replications for each treatment. types were placed in main plot, type digger secondary split depth plot. results showed no significant differences between potato diggers most studied traits. However, two-row recorded better than one-row digger, 83.60% undamaged tubers (UD) compared 81.07% digger. cultivar Actras achieved highest percentage UD total 85.18% 98.22%, respectively, Arizona 79.49% 95.00%. interaction 25 cm superior lowest bruised (3.99%) crop losses (7.88%).
