Summary

The influence of drip irrigation and traditional broadcast nitrogen fertilization as compared to drip fertigation was studied in field experiments. The yield of celeriac was highest with 1/3 preplant and 2/3 drip applied nitrogen, and lowest with broadcast nitrogen application without drip irrigation. Fertigated plants had greater leaf area, dry matter production, nitrate nitrogen and total N contents as compared to broadcast nitrogen application, both with and without drip irrigation. No significant differences in yield, dry matter production and contents of N03- -N and total nitrogen between surface and subsurface fertigation were stated.
