Abstract (eng)
The potato is an important energy source for humans. It contains great amounts of potassium, which lowers blood pressure. Vitamin C as well as the B-vitamins thiamine, niacin and pyridoxine are further important vitamins, stored in the tuber. They are essential for metabolism, controlling several physiological functions. The results of this work demonstrate various positive effects on human nutrition.
The empirical part of the thesis is dealing with an evaluation of three organically grown cultivars, their resistance against pests and plant diseases and their tolerance of dry growing conditions. The most important effects (e.g. fertile soil) for optimizing growing and developing of potato plants and tubers are discussed and the results are demonstrated. They are: a varied crop rotation, the use of legumes, organic fertilizer and an adequate tillage. Especially in dry areas like the Lower-Austrian „Weinviertel“ these measures play an important role in sucessful agriculture.
Potatoes are of high nutritive value but are much underestimated. Therefore teaching materials and concepts have been developed in the present thesis to highlight the importance of this food source.
