The article discusses historical aspects and modern effective approaches to sugar beet fertilization in Kazakhstan. The results of the first experiments, started in the 30s of the last century, showed differences in the effects of fertilizers depending on the type of soil. Studies have confirmed the effectiveness of nitrogen fertilizers on gray-earth soils and phosphorus fertilizers on light chestnut soils. In addition, it was found that the use of complete mineral fertilizers significantly increases the yield of sugar beet, especially in the dosage of N100P60K100. Attention is also drawn to the importance of the timing of fertilization: fertilization in the phase of formation of 3-4 pairs of real leaves in plants is more effective than later application. The role of organic fertilizers in improving the physico-chemical properties of the soil and increasing the yield of sugar beet is emphasized.
Studies conducted in our country have shown that it is effective to use a fertilizer system for sugar beet. The main requirements for mineral nutrition in the practice of growing sugar beet during its development: it is necessary to meet the needs for nutrients using a fertilizer system that includes seed and foliar nutrition.
According to the research results, the use of manure and mineral fertilizers has an effective effect on obtaining a high yield of sugar beet, as well as additional seed and foliar nutrition.
