The purpose of the studies, conducted in the years 2001–2003, was to examine the effect of the methods accelerating ripening (Ethrel, truss cutting, Ethrel + truss cutting) on yielding of two cultivars of small-sized tomato (‘Cheresita F1’, ‘Favorita F1’).

It was found that the total and marketable yield significantly decreased as a result of truss cutting. Ethrel did not increase either total or marketable yield whereas a significant increase in the yield of early tomato was observed after Ethrel application or Ethrel + truss cutting. ‘Cheresita F1’ gave a significantly higher total, marketable and early yield but produced smaller fruits. The use of plant growth regulators (Ethrel + truss cutting) limited the number of harvests to 7 and shortened the harvest period by 12 days in comparison with the control.
