Mechanize planting and harvesting operations for Jerusalem artichoke (Helianthus tuberosus L...) crop to reduce energy requirements and machinery cost. The field experiments were carried out through two agricultural seasons of 2005/2006 and 2006/2007. The planting operation was carried out under two mechanical feeding systems (automatic and semi-automatic),the automatic system was operated at forward speeds of 2.05, 2.89, 3.21 and 3:88km/h.While the semiautomatic system was operated at forward speeds of 1.21, 1.48, 1.85 and 2.27 km/h, and the harvesting operation was carried out under two mechanical methods (potato digger and ridger). Both of potato digger and ridger were operated at different forward speeds of 1.5, 2.04, 2.52 and 3.06km/h, by taking into consideration, the field capacity, required energy, tubers losses, total yield and cost analyses. The experimental results revealed the following points: The planting results showed that the tubers yield increased by 12.32% and 9.48% with automatic at forward speed of 2.05 km/h and semi-automatic at forward speed of 1.21km/h system respectively as compared with manual planting, the automatic system recorded the highest tubers yield of 18.020 Mg/fed at forward speed of 2.05 km/h, energy requirement of 57.23 kW.h/fed and operational cost of 70 L.E/fed. While the semi-automatic system recorded the highest tubers yield of 17.580Mg/fed at forward speed of 1.21km/h, energy requirement of 80 kW.h/fed and the operational cost of 125.26L.E/fed. The harvesting results showed that, the potato digger recorded the highest tubers yield of 18.020 Mg/fed, and lowest value of criterion cost of 2618.97 L.E/fed at forward speed of 2.52km/h. While the ridger recorded the highest tuber-y yield of 16.320 Mg/fed and lowest value of criterion cost of 4582.89 L.E/fed at forward speed of 2.52km/h.
