The experiment investigated the effect of different irrigation methods (no irrigation, irrigation by means of a drip tape) and method of AgroHydroGel application (control, AgroHydroGel applied to seedlings, AgroHydroGel applied to plants in the field, half of the AgroHydroGel applied to seedlings, the other half to plants in the field) on the yield level and quality of celeriac grown in the field. Irrigation significantly increased yields as well as the average weight of the marketable root; however, it had no influence on the nutrient contents. The application of AgroHydroGel to plants in the field or in a split proportion resulted in the most favourable influence on yielding. In the non-irrigated combination, AgroHydroGel applied entirely to plants in the field or in a split proportion increased marketable root yields. In the irrigated treatments, the highest yield was obtained in the plots where hydrogel was applied to plants in the field. Roots from the treatments where AgroHydroGel had been applied in a split proportion contained more dry matter as compared to the control. In the non-irrigated combination, AgroHydroGel applied entirely to plants in the field and in a split proportion increased ascorbic acid content. Simultaneously, irrigation and hydrogel application in a split proportion increased total sugar content as compared to the plants in which the hydrogel was only applied to the seedlings
