Abstract The aims of this study were:- 1- To investigate the feeding system has the ability to transplant the sugar beet seedling in field conditions. 2- Studies the parameters affecting the transplanting performances. The prototype design consists of the following parts; The feeding unit (The seedling system - Vertical conveyor - Elastic disc and Rollers press device), The minor Units (Cart holding seedling - Furrow opener and Coverers units) Methods & Results The following variables such as: four transplanter traveling speeds of 0.40; 0.80, 1.16 and 1.60 m/s. the seedling location on the horizontal belt are 5, 7 and 10cm which realizing the distance between seedling in row of 15, 21 and 30cm. The clearance between the feeding rubber discs is regulated by the roller press diameters therefore; three levels of roller press diameter of 15, 18 and 21 mm are used. The last variables parameters are the size or diameters of paper pot diameters, two parameters of 2.5 and 4.0 are recommended by the authors. The tests were replicated three times for each treatments of transplanter. • The maximum field efficiency of 76.6 % was obtained at forward speeding of 0.4 m/s and 2.5cm paper pot diameter and the minimum field efficiency of 62.6 % was obtained at forward speed of 1.6 m/s and 4.0 cm paper pot diameter. Recommendations:- Use the transplanter forward speed at 0.4 m / s, P.P.D 2.5 cm and 21 cm planting distances and 18 mm diameter rollers |
