Dneprovsky 257 is a simple modified corn hybrid developed by the Institute of Steppe Agriculture of NAAN of Ukraine. It belongs to the mid-early maturity group with FAO 290 and is intended for cultivation in various climatic zones, including Steppe, Forest-Steppe, and Polissia. The hybrid features a strong root system, plant height of 200–250 cm, and ear attachment height of 80–90 cm. The cylindrical ear, 20–22 cm long, contains 16–18 rows of kernels, with 36–40 kernels per row. The kernels are dent-shaped, yellow-orange in color, and the 1000-kernel weight is approximately 280–300 g.
Dneprovsky 257 exhibits high resistance to major corn diseases such as gray leaf spot and stalk rot, as well as pests. The hybrid possesses high drought and cold tolerance, making it suitable for regions with limited water availability and for early planting. It is resistant to lodging and does not tend to tiller, ensuring stable yields even with dense planting.
The hybrid is highly technological and responds well to the application of mineral fertilizers and foliar feeding, which contributes to achieving high yield potential. Grain yield is 120–125 c/ha, and silage mass yield is 580–630 c/ha. The grain dries quickly during ripening, facilitating harvesting and storage. Dneprovsky 257 is suitable for both grain and silage production, making it a versatile choice for agricultural enterprises.
