This research aims to study the effect of different treatments of potato plants with a
feeding organ on the growth and yield of potato crop and on the quality of tubers. The
Romano variety of potato was used, and the commercial organic feeder "plan
t energy
1000" was applied in four treatments. The treatments were: a control and three ways for
treating the plants with the organic feeder: by roots, foliage spray, and by both in one
treatment.
The completely randomized design was adopted in this experiment. The experiment
was implemented in the nursery farm of Tishreen University in the spring planting season
of 2012.
The results showed that treating potato plants with the organic feeder led in general
to an increase in the growth, which was reflected in the increase in the fresh weight, total
leaf area and its indication, as well as in the quality and number of tubers, total production
and marketing quality. These results were clearer in the case of the joint treatment: root
feeding and foliage spray together. This treatment showed significant superiority in
increasing production and improving its quality.
