The semi- automatic transplanter of sugar beet [electronic resource].

The aim of the present study has been concerned with a particular problem, associated with the sugar beet seedling transplanting. That aim was seen to be achieved through developing a transplanting machine with feeding system of the elastics disc which its idea depend on using the horizontal belt feed to vertical belt instead of using control guide. The general trend of this investigated that face the problem of little germination of sugar beet seeds in salted lands by using the seedling transplantation, and to control the row spacing in field. Under forward speed of 0.4m/s, the best results were obtained using feeding metering speed of 0.16 m/s. The theoretical distance was 29.5 cm and the actual distance was 32.45 cm. This was acceptable result as it was in the right limit (the interference is 10%). while by changing the seedling location from 7.0 to 10 cm to the highest value of seedling dispersion 10.3% was obtained under forward speed of 1.16 m/s with metering speed of 35rpm. The maximum field efficiency of 94.5 % was obtained at forward speeding of 1.5 km/h and the minimum field efficiency of 83.2 % was obtained at forward speed of 4.2 km/h.
