| Abstract | The article presents the results of research on the influence of plant density on yield formation and quality indicators of pink-fruited tomato hybrid Fujimaru F1 grown in modern glass greenhouses. The studies were carried out in 2024–2025 in industrial Venlo-type greenhouses using low-volume hydroponic technology. The greenhouse microclimate, irrigation regime, and nutrient solution supply were controlled by a Priva Integro climate computer system. The object of the study was the pink-fruited beef tomato hybrid Fujimaru F1 developed by the Dutch company Olan Agro, characterized by high fruit uniformity, a well-developed root system, and good transportability. The aim of the study was to determine the optimal plant density to ensure high yield and marketable fruit quality under greenhouse conditions. Three plant density treatments were tested in the experiment: 2.5, 3.1, and 3.6 plants per m². The experimental plot area was 10 m² with four replications. Tomato plants were cultivated according to the recommended technology for winter greenhouse production. Yield data were recorded throughout the entire fruiting period from March to November. The results showed that plant density significantly affected tomato productivity and fruit quality. Increasing plant density resulted in higher yields but led to a decrease in the average fruit weight and marketability. The average yield over two years in the control treatment (2.5 plants per m²) was 39.9 kg/m². Increasing plant density to 3.1 plants per m² increased yield to 41.7 kg/m², which was 1.8 kg/m² or 4.5% higher than the control. The highest yield (43.7 kg/m²) was obtained at a density of 3.6 plants per m²; however, this treatment showed a more pronounced decrease in average fruit weight and fruit marketability. Taking into account the combination of yield and fruit quality indicators, the most effective plant density for growing the pink-fruited tomato hybrid Fujimaru F1 in glass greenhouses was 3.1 plants per m². This density ensures an optimal balance between high productivity and high marketable fruit quality. | ||
