Soybean is one of the leading protein-oil crops in global agriculture, possessing a unique composition and high nutritional properties. Soybeans contain a significant amount of protein, B vitamins, as well as vitamins A, C, E, and H. Additionally, soy is rich in trace elements such as sodium, calcium, magnesium, potassium, phosphorus, iron, iodine, boron, and zinc. Special importance is given to the presence of isoflavones, which help compensate for estrogen deficiency in women during menopause, while the high calcium content contributes to bone strengthening and osteoporosis prevention.
Soybean is a light-loving and heat-loving crop, requiring a significant thermal regime for successful cultivation. For early varieties, such as 'Find', the optimal sum of effective temperatures during the vegetation period ranges from 1700 to 2000 °C. The most critical phases for plant development are flowering, pod formation, and seed filling, when high soil moisture — around 70–80% — is required. Soybean is relatively drought-tolerant in early growth stages, but requires adequate watering during flowering and seed formation. Proper soil preparation, selection of preceding crops, fertilization, as well as protection against diseases and pests play a key role in ensuring high yields.
Soybean is not only an important source of plant protein and oils, but also contributes to improving soil nitrogen balance, positively affecting subsequent crops. Soybean yield allows for significantly higher protein production per hectare compared to other cereal and leguminous crops. Recent discoveries of wild soybean varieties with increased protein content open new prospects for selection and improvement of cultivated varieties, making this crop even more valuable for agricultural production and the food industry.
