Precultivated cauliflower seedlings (cultivar Chambord F1) were used in this study with the aim to evaluate the influence of the hydrophilic agent Agrisorb (3 g Agrisorb/L of substrate) on the weight and height of aerial parts, weight of roots, number of leaves and root collar diameter. The seedlings were planted under two different irrigation levels with two levels of available water capacity - 80% (optimal) and 50% (reduced). The influence of Agrisorb on the following characteristics of cauliflower edible parts was evaluated after harvest: weight, diameter, percentage representation of marketable parts, market yield, concentrations of ascorbic acid, nitrates and dry matter, and total antioxidative capacity value. The addition of Agrisorb significantly increased the weight of aerial parts by 17.3%, the root weight by 28.1%, and the number of leaves by 7.9%. After harvest, it was noted that Agrisorb significantly increased marketable yield (by 17.5%) and decreased total antioxidative capacity (by 19.9%) in the treatment with reduced irrigation level.
