INFLUENCE OF HUMIC PREPARATION ON PHOTOSYNTHETIC INDICATORS AND YIELD OF TOMATOES IN PROTECTED SOIL

This article presents the results of a study of the effect of the growth stimulator humate "Healthy Harvest" on the accumulation of photosynthetic pigments in the leaves of tomato plants. The experimental study was conducted on the territory of the SPK "Beregovoy", in a film unheated greenhouse, with an area of 500 m2 in 2024. The object of the study were 3 mid-ripening hybrids: Matissimo, Melodiya, Martez. The tests were carried out according to the method of S.S. Litvinov "Methodology of field experiment in vegetable growing". Based on the studies, it was found that the effect of using the humate preparation "Healthy Harvest" in growing tomato plants had a significant impact on the accumulation of photosynthetic pigments and increased yield. The greatest accumulation of photosynthetic pigments occurs in tomato plants with seed soaking and treatment in the 7-8 leaf phase, especially in the Melodiya F1 hybrid, compared to the control variant, the content of chlorophyll a was 2.55 times, chlorophyll b - 2.37 times, carotenoids - 3 times more. A significant increase in yield in all tomato hybrids was obtained with seed soaking and treatment in the 7-8 leaf phase and amounted to 28.7 kg / m2 in the Melodiya F1 hybrid, 25.7 kg / m2 in Martez F1, 23.4 kg / m2 in Matissimo F1.
