The experiments were carried out in 1998–2000 in a unheated plastic tunnel. The effects of single plants topping on the quantity and quality of the yield of three cultivars of eggplant (Solanum melongena L.) – ‘Black Beauty’ ‘Solara F₁’ and ‘Epic F₁’ in the experiment was determined. No significant influence of the method on the marketable yield and the number of fruits in marketable yield was found. Plants topping also had no positive effect on mean weight of marketable yield fruit. Results achieved in present experiment point out that fruit size (length and diameter) more depends on cultivar and weather course than plants topping procedures.
