Abstract
Experiments were carried out using a developed mechanical `feeding unit using feeding belt with cells on its out surface to study the effect of linear speed of feeding belt, speed ratio between conveyor belt and feeding belt, seedling bulb diameters and cell width of feeding belt on onion seedlings properties (seedling feeding rate, inclined seedlings percentage, damaged seedlings percentage and average seedlings spacing) and power consumed. The best results of seedlings feeding rate were 153 seedlings/min, inclined seedlings percentage 5.69 %, damaged seedlings percentage 3 %, average seedlings spacing (11-12 cm) and useful power consumed 0.0994 kW. This data were obtained at operating the developed mechanical feeding unit at linear speed of feeding belt of 0.347 m/s, relative linear speed of 1.33, feeding belt cell width of 3 cm and by using onion seedlings with diameter of (> 5 < 10 mm).
