Dana soybean is an ultra-early maturing annual herbaceous variety, developed by Ukrainian breeders using individual selection methods. Plants reach a height of 70-90 cm, have a compact, bushy form with narrow dark-green leaves and white flowers. The maturity period is 81-85 days, allowing the variety to be grown in various climatic zones of Ukraine, particularly in forest-steppe and Polissia regions. The variety is registered in the Ukrainian Variety Register and recommended for intensive cultivation technologies, including main and inter-row sowings. Dana soybean is characterized by high grain yield, reaching 25-35 c/ha, with a potential yield of about 4.0 t/ha. Seeds are round-oval in shape, light-yellow in color with a light hilum and cotyledon, with a 1000-seed mass ranging from 150 to 175 g. The seeds contain 37-42% protein and 19-28% oil, making this variety a valuable source of nutrients and essential oils. The recommended planting density ranges from 450,000 to 1.2 million seeds per hectare, depending on growing conditions, with a planting depth of 4-5 cm. The variety is resistant to multiple diseases and stress factors, as well as highly adaptable to unfavorable growing conditions. It does not overwinter in open ground, so it is grown using direct seeding. Due to its qualities, Dana soybean is a reliable predecessor for winter crops and widely used in dietary nutrition due to its high protein and nutrient content.
