The experiment was carried out in 1997-99. The aim of the study was to compare the effect of various truss cutting methods on the yield, quality and storage life of small sized (cocktail) tomato cv. Camelia. Three methods of truss thinning (leaving 12 or 16 fruits per truss and not thinning trusses) and three different storage times (2, 3 and 4 weeks), were tested. The experiment was performed in a high, unheated plastic tunnel, in the middle of May. Truss thinning to 12 fruits had a significant effect, decreasing total yield by 1.27 kg and marketable yield by 0.94 kg/square m in comparison with the yield obtained from control plants. Truss thinning had a positive influence on the early yield of tomato. Thinning to 12 fruits increased early yield by 0.19 kg/square m in comparison with the control. Furthermore, truss thinning increased the weight of marketable fruits. These fruits retained higher quality after 2, 3 and 4 weeks of storage, they were firmer than fruits from control trusses. Lycopene content increased while beta-carotene and vitamin C contents decreased after 2 weeks of storage
