EFFECT OF NITROGEN FERTILIZATION AND BIOFERTILIZATION ON ELEMENT CONTENT OF PARSLEY

A pot experiment was carried out to investigate effect of N fertilizer and biofertilizer on parsley (Petroselinum tuberosum) yield and N, P, K, Ca and Mg content. Two soils were used, one of them is a chernozem with slightly acidic pH and with high content of organic matter, and the other one is an acidic sandy soil with low organic matter content. On chernozem, the N fertilization significantly increased the yield of plant, while there was no significant biofertilizer effect. On sandy soil, the dry matter of plants, increased with increasing N doses comparing to control, but no correlation has been found between biofertilization and dry matter weight. The N fertilization increased the N content of parsley, however, no relationship was found between N content and biofertilization rate in chernozem soil. In case of the sandy soil, there was a statistically confirmed N fertilization effect on plant N concentrations. The P content of parsley was enhanced by both N fertilization and biofertilization on the chernozem soil. With increasing of N doses P content decreased significantly, while application of biofertilizers caused no any change in P concentrations. For both soils, both N fertilization and biofertilization has no effects on parsley K content.
