An Evaluation of the Biometric Parameters and Chemical Composition of the Florets, Leaves, and Stalks of Broccoli Plants Grown in Different Soil Types

Abstract

Soil affects plant growth and development, and it is one of the factors that determine crop yields and quality. Broccoli (Brassica oleracea var. italica Plenck) plants cv. Cezar were grown in an experiment conducted in 2021–2022 on a horticultural farm. The biometric parameters of broccoli plants were determined in the first stage. The chemical composition of the edible parts of broccoli was determined in the second stage, which involved two experimental factors. The first factor was the edible parts of broccoli: florets, leaves, and stalks. The second factor was the effect of soil type on the chemical composition of the edible parts of broccoli. Albic Luvisol (II) had a significant positive effect on floret height and the number of florets. Leaf yield was significantly lower when broccoli plants were grown in Eutric Cambisol (I) compared with Albic Luvisol (II) and degraded chernozem (III). Soil type had no significant influence on the macronutrient content of broccoli florets, leaves, and stalks, but the accumulation of macronutrients varied across the edible plant parts. The content of iron, zinc and manganese in broccoli plants was not significantly affected by soil type, but soil type exerted a significant effect on copper content.
