| The aim of the investigation is to study the effect of the planter forward speed, spacing between seeds and ridging time on the germination, lateral deviation, double and void tubers percentage, productivity, power and energy requirement. The field experiments were conducted at forward speeds of 2.0, 2.7 and 3.6 km/h, planting depths of 14, 17 and 20 cm spacing between seeds of 25, 30 and 35 cm under ridging with planting and ridging after emergence. The results revealed that the forward speed has a negative effect on germination; lateral deviation, productivity, energy requirements and positive effect on the double and void tubers percentage. Meanwhile, the planting depth has a negative effect on the germination, productivity and positive effect on the lateral deviation, power and energy requirement. The ridging after emergence gave a significant increase of the germination and productivity as compared with ridging with planting. The highest germination of 98.6% was found at forward speed of 2.0 km/h, spacing between seeds of 30 cm, planting depth of 14 cm without ridging during planting (ridging after emergence). Meanwhile, the highest productivity of 11.21 ton/fed. was obtained at forward speed of 2.0 km/h, spacing between seeds of 25 cm, planting depth of 14 cm with ridging after emergence.The lowest double tubers of 3.3%, void tubers of 2.9% were found at forward speed of 2.0 km/h., but the minimum value of lateral deviation of 10.68% was found at forward speed of 3.6 km/h. The highest power requirements of 40.85 kW was obtained at forward speed of 3.6 km/h and planting depth of 20 cm. While the lowest energy requirements of 31.69 kW. h/fed. was found at forward speed of 3.6 km/h and planting depth of 14 cm. | ||
