Abstract
In our series of experiments celery test plants were used in lysimeter type pots. Plant growth, nutrient content and the relationships of them were observed. This publication shows the effects of different doses of nitrogen fertilizer (absolute control, basic +60/120/180 kg/ha N, and the base + 240 kg / ha N (calculated N from manure). The nitrogen content of the celery increased significantly depending on the N-doses; and a strong positive correlation (r = 0.815, p < 0.025 level) was detected in the tubers between N content and vitamin C. Our results establish that in our experimental setup on sandy soil, organic fertilization - enriching the colloid content and improving soil structure - proved to have the most beneficial effects.
