RESPONSE OF LATE WHITE CABBAGE TO FERTIGATION AND BROADCAST NITROGEN APPLICATION

Summary

Research was conducted in 1997-1998 on response of late white cabbage on drip irrigation and traditional broadcast fertilization as compared to liquid fertilization. Use of fertigation with nitrogen or multiple fertilizer "Polyfeed" has caused a significant rise in the yield of late white cabbage considering the traditional, broadcasted use of nitrogen. Liquid-applied fertilizers were utilized more effectively as compared to broadcast-applied nitrogen. Lowering the dose of nitrogen in fertigation from 200 to 125 kg/ha has not decreased the yield significantly. Due to fertigation of nitrogen or multiple fertilizer, the nitrogen status of plants was uniform within the whole growth period and markedly better than that obtained by dredge-applied nitrogen fertilizing. No differences in yield, dry matter production and contents of nitrate and total nitrogen have been stated between surface and subsurface fertigation.
