Application of organic fertilizers in the cultivation of early potatoes in the Non-Chernozem zone

The results of studies on the effect of organic fertilizers on the formation of early potato harvests in the Non-Chernozem zone are presented. Potatoes are one of the main agricultural crops that are in demand during the winter season, but the demand for early potatoes does not decrease during the summer season, as the previous year's supplies are running out. Early potato varieties are sold fresh to the public and are recommended for table use. In the extreme farming zone, which includes the Moscow region, it is important to choose the right variety and cultivation methods. The use of promising technologies for growing early potatoes is an important area in vegetable growing. The search for resource-saving techniques to increase productivity and product quality while reducing production costs remains relevant. The purpose of the research: to study the influence and effectiveness of organic and organomineral fertilizers on the development of potato plants and the formation of yields in the early stages. The experiment was conducted in 2024-2025 at the Horticulture and Vegetable Growing Research Center with local varieties of early potatoes. Organic preparations Rostovit, Omek-7, and Aminozol were used to optimize growing conditions and develop plant resistance to adverse factors. These broad-spectrum preparations promote the formation of a strong root system and increase crop yields. The aim of the study was to investigate the impact and effectiveness of organic fertilizers on potato plant development and early yield formation. The highest yield was observed in the Riviera variety with Rostovit, reaching 32.6 tons per hectare, which is 15% higher than the control variant. When treated with Rostovit, an increase in productivity was observed due to the mass of tubers in all fractions and their quantity. The minimum increase was observed in the variant with Omek for both varieties. On average, over two years, the increase was 4% for the Riviera+Omek variety and 6% for the Colomba+Omek variety.
