Abstract. Various forms of nitrogen fertilizer were applied for cultivation of red cabbage, ‘Langendijker’ c.v.: control (unfertilized with nitrogen), Ca(NO3)2, (NH4)2SO4, NH4NO3, CO(NH2)2. Nitrogen treatment, irrespective of the applied fertilizer form, increased total yield of cabbage in comparison with the control. The highest N-total, K, Mg and Ca concentrations were found in heads of plants fertilized with Ca(NO3)2 and CO(NH2)2.

Key words: nitrogen fertilization, nitrogen, macro components, red cabbage

 

The effect of fertilizer nitrogen form on the amount of yield
and content of selected macro components in red cabbage

Summary

The experiments with field cultivation of red cabbage ‘Langendijker’ c.v. were conducted in 2003-2005 at Grębałów near Cracow. Plants fertilized with the following forms o nitrogen fertilizer were researched: 1 – control (non-fertilized with nitrogen, 2 – Ca(NO3)2, 3 – (NH4)2SO4, 4 – NH4NO3 and 5 – CO(NH2)2. Treatment with individual nitrogen forms caused an increase in yielding in comparison with the control ranging between 17.5 and 23.2%. In comparison with the control nitrogen fertilization raised the degree of plant nitrogen and potassium enrichment. The highest contents of N-total, K, Mg and Ca were registered in the heads of plants fertilized with Ca(NO3)2 and CO(NH2)2.
