Описание
The present study proved that we can produce organic potato in sandy soil by using 100% compost without any significant differences in tubers yield per fed. as comparing to the conventional fertilization. Using compost treatment exceeded all biofertilizer treatments in marketable yield, without significant differences compared with mineral fertilization. Using compost significantly exceeded mineral fertilization in concentration of nitrogen, increasing concentration of phosphorus and Potassium in leaves. There were no significant differences between using compost and mineral fertilization in nitrogen, phosphorus, Potassium, starch and dray matter concentration in tuber. Compost application had significantly lower nitrate concentration in tuber than mineral fertilization.
