Influence of Organic Humic Fertilizer “Tumat” on the Productivity of Sugar Beet

Abstract

The production of sugar beet in the Republic of Kazakhstan is insufficient to meet the domestic sugar needs of the population. This shortfall is attributed to the natural and climatic conditions, the high cost of production, and the low use of mineral fertilizers. The objective of the study is to investigate the impact of the organic humic fertilizer “Tumat” on the growth, development, yield, and sugar content of sugar beet in the conditions of irrigated light chestnut soils in Southeast Kazakhstan. Scientific research confirms the effectiveness of using the organic humic fertilizer Tumat for cultivating sugar beets. This fertilizer is highly bioavailable and contains a balanced mix of essential macronutrients and micronutrients, polyunsaturated fatty acids, and other biologically active substances. Foliar feeding of sugar beets enriches the soil with exchangeable potassium, mobile phosphorus, and easily hydrolyzable nitrogen during the plant’s vegetative period. Using the Tumat fertilizer enhances plant germination rates by 6.0–16.0%, stimulates growth and development, accelerates the ripening of sugar beets, and increases the yield of tubers by 10.5–15.2%, sugar content by 0.4–0.7%, and sugar output by 13.6–20.8%. An organic humic fertilizer, is recommended as an environmentally safe and effective agricultural product that boosts the productivity and quality of sugar beets, as well as soil fertility.
