In the years 1998-2000 studies aiming at the evaluation of yielding and quality of small-sized tomato grown in the field and their storability were conducted. The yields of three Polish cultivars: ‘Maskotka’, ‘Ola’, and ‘Pinokio’ were compared. The tomatoes were spaced as follows: 50×40 cm (5 plants per 1 m2) and 40×30 cm (8.3 plants per 1 m2). The results of three-year studies showed that the increase in plant density caused a significant increase in the total, commercial, and 1st class fruit yield in all the tomato cultivars under study. It was found that the early yield of ‘Pinokio’ was significantly lower in comparison with the other two cultivars. Particular cultivars of small-sized tomato differed highly significantly in their qualitative characteristics. ‘Ola’ produced fruits of the greatest weight, diameter, and the thickest pericarp. Storability and the percentage of weight losses were also analysed after 1, 2, 3, and 4-week storage period in a cool chamber. It was found that storability and weight losses did not depend on plant spacing or cultivar but on the storage period. After 3 weeks all the tomatoes had poor storability (below 60%) and weight losses were higher than half of the plant mass placed in the cool chamber.
