Humate-based biologics in the technology of tomato growing in the open ground of the republic of Dagestan

Dagestan annually harvests more than 1 million tons of outdoor vegetables. In 2023, up to 1.5 million tons of vegetables were harvested in the region. Cabbage accounts for more than 50% of Dagestan's vegetable production, tomatoes account for more than 26%, and cucumbers, carrots, onions, garlic, table beets and other crops are grown here in significant quantities. The purpose of the research is to evaluate the effectiveness of using a domestic biological product (Relict R) on domestic tomato varieties when they are grown in the open ground. The research was conducted in 2022-2024 in the open ground in the Tersko-Sulak sub-province of the Babayurt district. A comparative assessment of the effectiveness of the use of biologics Humate+7 and Relict R on tomato plants of the Voskhod variety bred at VNIISSOK is given. The highest plant height was noted in variants with top dressing of Relict R. The difference compared to the control after the first top dressing was 3.3 cm, after the second – 5.3 cm, after the third – 6.7 cm, after the fourth – 4.6 cm, after the fifth – 7.3 cm. In the course of our research, tomatoes fed with biologics Humate+7 and Relict P exceeded the control in yield in g/m2 and fruit weight. The highest yield was observed with top dressing with Relict P (exceeding the control by 300 g/m2) and Humate +7 (by 200 g/m2) at each tomato harvest. Biochemical analysis of tomato fruits showed a dry matter content from 6.4% (Humate +7) to 6.9% (Relict P). In the control variant, the dry matter content was 5.9%.
