During the period 2022-2023 was studied, the morphological characteristics were monitored of a greenhouse tomato: plant height, number of leaves, number of inflorescences and number of buds per plant in different variants of treatment with organic fertilizers. The results of the morphological analysis show that in terms of plant height, the variants that were fed with organic fertilizers, on average for the studied period, exceed the unfertilized control by 12.2% to 18.5% for Vermilenza and by 14.3% to 23.6% for Grando. The application of fertilizers increases the development index in the studied tomato varieties. With application of the organic fertilizer Siapton, the highest values were recorded for the Grando variety - 10.50 and for the Vermilenza variety - 7.63. A strong positive relationship was established between the indicators 'plant height' and 'total yield', with a correlation coefficient for the Grando variety r = 0.91, and for the Vermilenza variety r = 0.89. The nature of the linear relationship between the indicators 'plant height' and 'number of inflorescences' was determined, with a coefficient of determination R² = 0.846 for the Grando variety and R² = 0.797 for the Vermilenza variety.
