Maize DN Kiyahy

DN Kiyahy is an early modified hybrid of sweet corn with FAO 190, registered in the Ukrainian Plant Variety Register since 2022. It is intended for grain and silage production and is characterized by versatility and high cold resistance, allowing it to be grown in various climatic zones, including Steppe, Forest-Steppe, and Polissia, as well as in northern countries with cool climates. Hybrid plants reach a height of 220-260 cm, have a conical-cylindrical ear shape 21-24 cm long, attached at a height of 90-100 cm. The grain is yellow-orange, cream-serrate, oval-long shape, with a 1000-grain weight of approximately 270 g.

The DN Kiyahy hybrid exhibits high grain yield — 11.5-13.0 t/ha, exceeding the standard DN Pivihya by 0.42-0.84 t/ha at the same grain moisture level at harvest. It rapidly accumulates dry matter and is characterized by intensive moisture release from the grain, facilitating drying. Plants are resistant to root and stem lodging, have high cold, drought, and heat resistance, as well as resistance to diseases such as corn smut and fusarium.

DN Kiyahy responds well to improved growing conditions and can develop even on soils with low agrofertility. The recommended planting density varies depending on the growing zone: in Steppe — 55-65 thousand plants per hectare, in Forest-Steppe — 70-80 thousand/ha, in Polissia — 80-90 thousand/ha. Thanks to its characteristics and adaptability, this hybrid is an effective choice for farmers aiming to achieve high and stable yields under various climatic conditions.
