The effect of harvesting opration on potato crop handling [electronic resource]. تأثير عملية الحصاد على تداول محصول البطاطس. p.492-503. Includes references. This study aimed to investigate the effect of some operational factors related to harvesting machine on damage and unlifted potato tubers. These factors included: Three different forward speed 3.02, 4.25 and 5.2 km/h, three different chain speeds 2.3,3.5 and 4.65 km/h, three different agitation throw-out zero, 1and 2 cm, three different chain inclinations 15, 20 and 25 degree, three different harvesting depths 10, 16 and 22 cm and soil moisture content 15, 20 and 25% and storage time after harvesting 0,1,2,3 and 4 week. The experiments were carried out in Nubaria location, el-Bheara Governorate in 2006. From the obtained results, it was cleared that the proper condition to operate the harvesting machine were 22 cm harvesting depths,5.2 km/h forward speed, 4.65 chain speed, zero agitation throw-out, 15% soil moisture content and primary chain inclination of 15 degree. The moisture content of potato tubers varied with storage time after harvesting. Summary in Arabic. Potatoes Breeding. Potatoes Growth. Potatoes Harveting. Potatoes Handling.
