Evaluation of Minitubers Yield and Scaling which Produced from Microtubers Transplanting Using Soilless Culture Technique

The results of the experiment showed that the variety santa was significant superior than draga in leaf area, mean number of tubers.plant-1, total yield. plant-1 and the percentage of number of tubers with the size 1.5- 2 cm, which reached 9.3, 26.56, 6.34 % and 47% respectively there were no differences between them in the tuber sizes of 2-3 cm. the draga variety significantly differ than santa on the tubers size 0.7-1.5 and 3-5 cm and the ratio was 2.5% and 79.8%, respectively. the growing media m1 significantly superior than m2 and m3 in leaves area, numbers of minitubers and total yield.plant-1 reached 26.26dcm2, 19.69 minitubers and 427.37g .plant-1 respectively. the media m3 significantly differed from m2 and m1 in the tubers size 3-5cm and theeir ratio were 19.0%, 15.8% and 15.2% respectively. the draga variety in m2 media significantly differed than santa in m1 media in differed from tubers size and the ratio reached 20.5% and 10.1% respectively.
