Corn AV 403 MS is a simple modified mid-early maturity hybrid with FAO 290, intended for cultivation as grain or silage. This hybrid stands out for its high yield potential, reaching up to 14 tons per hectare, making it an attractive choice for farmers aiming for maximum productivity. The grain has a dent structure and yellow color, and the ear is cylindrical with 14-16 rows of kernels. Plants reach a height of about 220 cm, with the ear positioned at approximately 110 cm. The hybrid has medium ability to form two ears, further increasing its yield potential. One of the key features of AV 403 MS is its high grain drying intensity after maturity, significantly reducing costs for additional drying and accelerating harvest. The hybrid adapts well to various soil-climatic conditions, especially excelling in the Northern Steppe of Ukraine. High drought and cold resistance (8 out of 9 points) ensures stable yields even under adverse weather conditions. Additionally, the corn shows good resistance to major diseases such as common and aerial smut, as well as the corn borer. Its versatility makes AV 403 MS a cost-effective solution for farmers interested in producing both quality grain and silage. High adaptability and resistance to stress factors allow this hybrid to be used in various agronomic systems, ensuring stable and high yields. Thanks to the combination of productivity, reliability, and versatility, corn AV 403 MS is an optimal choice for modern agricultural enterprises.
