VARIATION OF SOME PARAMETERS IN EARLY CABBAGE IN RELATION TO FERTILIZERS - COMPARATIVE EVALUATION

Abstract

The variation of some morphological parameters and physiological indices in cabbage (Brassica oleracea var. capitata) in relation to fertilization was evaluated. The experiment was carried out under greenhouse conditions, agricultural year 2023-2024. The early cabbage hybrid 'Gazelle F1' was cultivated. Fertilization was done with Natur Complet G (12.5 kg/400 m2) by incorporation into the soil, respectively Terranova (500 ml/400 m2) and Naturamin WSP (10 g/10 L water), with fertigation application. A control variant was considered for comparison. Total plant biomass (TPW, g), head fresh biomass (HFB, g), leaf fresh biomass (LFB, g), leaf dry biomass (LDB, g), leaf ash content (LAC), root fresh biomass (RFB, g), root dry biomass (RDB, g), and root ash content (RAC, g) were determined. The comparative analysis showed differences with statistical safety generated by fertilization for TPB and HFB (p<0.001), LFB (p<0.01), and LDB (p<0.05). Multivariate analysis showed positive action of parameters, and variable level of intensity in relation to the principal components. The positioning of plant parameters changed in the structure of the principal components, in relation to the fertilization variants.
