Abstract
The experiments were carried out at El-Maamoria village- El-Gamalia region, Dakhlia Governorate during onion harvesting season 2008-2009 to evaluate onion harvesting crop by a combine machine for harvesting and collecting onion cropandachieving the following factors: Decreasing harvesting costs of onion crop, Decreasing a partial and total damage caused in onion bulbs, Decreasing harvesting period and Easing of collecting onion crop. by using a developed combine machine to harvesting and collecting of onion crop. All treatments were carried out on onion crop at four different speed ratios K (ratio of elevator speed to machine forward speed) (K1=1.8, K2= 1.55, K3= 1.05 and K4= 0.8) and four different tilt angle of share (T1=10, T2=15, T3=20 and T4=25 degree) with different four depths of share (D1=4, D2= 5.5, D3=7 and D4=8.5 cm ).The best results of harvesting efficiency, damage ratio and fuel consumption were at (K3= 1.05, T4=25 degree, D3= 7 cm).
