Hybrid corn MAS 33A is a versatile mid-early variety with FAO 320, designed for extensive cultivation technologies. The plant is tall, reaching heights from 151 to 200 cm, with a strong and well-formed ear 19-22 cm long and medium density of kernels. The ear contains 14-16 rows of kernels, each row with 33-37 dent-shaped yellow kernels. The thousand kernel weight is 320-340 g, ensuring high yield and good milling quality — 81-82%. MAS 33A exhibits high resistance to adverse conditions, including drought and lodging, as well as tolerance to major diseases such as Fusarium ear and stalk rot, and powdery and downy mildew. The hybrid shows rapid early growth and high energy for emergence, promoting stable plant development. Due to its high nutritional and vitamin content in silage, as well as its versatility, this hybrid is suitable for both grain production and silage and root crops. Recommended planting density is 70-80 thousand plants per hectare under adequate moisture and 60-70 thousand under unstable moisture. MAS 33A is successfully grown in various climatic zones, including forest-steppe, steppe, and meadow regions. Grain yield reaches 14 tons per hectare, and silage yield — up to 70 tons per hectare, making this hybrid a profitable choice for farmers aiming for high and stable yields.
