Maize DN Sinewir

DN Sinewir — a high-tech three-line early-maturing hybrid sweet corn with FAO 190, developed by the Institute of Agriculture of the Steppe Zone of NAANU and registered in the State Register of Ukraine since 2017. This hybrid is primarily intended for grain production, but is also suitable for silage use. Plants reach a height of 230–250 cm, with cylindrical ears 21–23 cm long, bearing 16–18 rows of kernels, 36–38 kernels per row. Kernels are yellow, dent-shaped, with a thousand-kernel weight of 270–280 g, and the ear stalk is red. The hybrid features a strong, sturdy stalk resistant to lodging, and leaf mass remains intact without shedding.

DN Sinewir demonstrates high yield potential, reaching up to 11.5–14.3 t/ha depending on growing conditions. Best results are achieved in forest-steppe and Polissia regions, as well as in steppe areas of Ukraine. The hybrid exhibits moderate water-use efficiency during grain maturation and accelerated dry matter accumulation, which is particularly valuable for northern ecotypes. It shows high cold tolerance, enabling successful growth even during sudden spring frosts, and also possesses heat- and drought-resistance.

Throughout the entire vegetation period, plants remain resistant to diseases and pests, reducing the risk of yield loss. The hybrid responds well to seeding density and is recommended for cultivation with plant density at harvest time: 60,000 per hectare in steppe regions, 80,000 in forest-steppe regions, and 90,000 in Polissia. Thanks to its agronomic characteristics and stable yield, DN Sinewir is a reliable choice for farmers focused on producing quality grain and silage.
