An Evaluation of the Physical and Chemical Parameters in Brassica Seedlings Grown on Various Organic Substrates

Horticultural substrates should promote seed germination and seedling emergence. The value of the SPAD index was significantly influenced by type substrate. had a beneficial effect on plant height in comparison with control Brassica plants grown used experiment compact growth habit, which is desirable trait production. In general, macronutrient uptake differed various substrates. Significant differences this parameter were observed mainly broccoli (increase approx. 14%) white cabbage (decrease 30%) PRO2, all PRO3 9% broccoli, decrease 33% cabbage, 15% cauliflowers). decreased total micronutrient concentrations leaves around (PRO1) to 40% (PRO3) relative treatment, levels cauliflower increased 12% PRO1 35% PRO3. content 24% PRO1, 20% PRO2 PRO3, respectively, treatment.
