Megjegyzések:	Ecological farming is getting even more wide spread, in horticulture as well, within that - beside fertilizers - the organic manure and bacteria fertilizers are becoming more and more important. In our comparing experiment we studied the effect of mineral fertilizer and bacteria fertilizer on the dry matter production and nitrogen-content of parsley (Petroselium crispum) and on the 0,01 M CaCl2-soluble N-content - that is easily taken up by plants - of two different soil types. In the second year of our experiment we used only mineral fertilizer, so that we could reveal the after effect of bacteria fertilizer (Philazonit-MC). The results of our experiment are the following: On the chernozem soil the N-fertilizer significantly increased the dry matter production of parsley. On the other hand the bacteria fertilization on the same soil type in the first vegetation period only trended to, contrarily in the second vegetation period significantly increased the dry matter of parsley. On the sandy soil - in both years - the N-fertilization trended to increase the dry matter production of plants, but bacteria fertilization - also in both vegetation periods - with higher amount of nitrogen added resulted a dry matter yield increment, while with a lower amount of nitrogen added it decreased the dry matter production of plants. The effect is not proven by statistical analysis. A positive significant effect was detected on the chernozem soil between N-fertilization and the N-content of plants. Bacteria fertilization contrarily did not have any influence on it. On the sandy soil N-fertilization resulted a N-content increment in both vegetation periods. The positive effect of bacteria fertilization could be revealed in the second year. N-fertilization increased the 0,01 M CaCl2-soluble N-content of chernozem soil in both years. This effect is also statistically proven. Bacteria-fertilization, however in the first year significantly increased, in the second year trended to decrease the 0,01 M CaCl2-soluble N-concentration of the chernozem soil. We could reveal a positive significant effect between the 0,01 M CaCl2-soluble N-content of the sandy soil and the N-fertilization in both vegetation periods. Bacteria-fertilization showed a trend to decrease this content. To draw further conclusions other examinations are needed in the future.
