In the pot experiments, the effect of single mineral fertilization with nitrogen, phosphorus, and potassium, and of the joint NPK action on the overall crop of celery and on changes in the content of chlorophyll, sugars and ascorbic acid were investigated. The results of the investigation showed that high nitrogen, phosphorus, and potassium content of the soil leads to a smaller the crop, and at same time the biological values of the plants. Moreover, tests with celery have shown that the fertilizing rates optimal in terms of the crop do not guarantee the highest nutritional values of the vegetable.
