The corn variety Donskaya High-Yielding 2 belongs to the dent group and is medium-maturing with a vegetation period of 110-120 days (FAO 450). The plants of this variety are tall, reaching 250-350 cm in height, have wide leaves and high leafiness. Conical ears, 25-30 cm long, are located high on the plant (100-120 cm), and most plants form two ears. The kernels have yellow coloring of varying intensity, with a 1000-seed mass of 280-300 g. The kernel type is intermediate, with yellow-orange coloring of both upper and lower parts.
Donskaya High-Yielding 2 is a versatile variety intended for use both as grain and for silage. One of the important biological features of this variety is the retention of green leaf-stem mass at full grain maturity, enabling efficient use for silage production. Green mass yield reaches 450-550 centners per hectare, and under favorable conditions, grain yield may exceed 100 centners per hectare, as confirmed by variety trials in various regions.
The variety is characterized by high productivity and resistance to adverse weather conditions due to its prolonged flowering period, which ensures pollination and seed setting even at unfavorable temperatures. To achieve maximum yield potential, the variety should be cultivated on a high agro-technological background with optimal plant density, which varies depending on growing conditions and crop purpose. Donskaya High-Yielding 2 is a reliable choice for agricultural producers seeking high and stable yields of grain and silage.
