Corn hybrid KWS 2322 is a mid-early plastic hybrid with dent-type grain, characterized by high moisture shedding intensity, making it ideal for early harvest. Plants reach a height of 250 to 290 cm, with ear attachment at 100-110 cm. The ear is of medium length and thickness, with 12-16 rows of kernels and 34-42 kernels per row. The 1000-kernel weight is approximately 290-300 g, indicating good kernel development and density. The kernel type is intermediate, with yellow upper and orange lower parts, giving the kernels an attractive appearance.
The hybrid is included in the State Register for the Central Chernozem region and shows high yield potential, reaching 130-140 c/ha. The average yield in the region is about 75.7 c/ha, with maximum yields up to 115.6 c/ha, exceeding the standard by 14%. The vegetation period is approximately 114 days, which is 2 days shorter than the standard, and the grain moisture at harvest is at 20.6%, 3.9% lower than standard values. Early flowering contributes to high performance under hot conditions, and the hybrid responds well to high agronomic fertility.
The recommended planting density at harvest varies depending on conditions: 75-85 thousand plants per hectare under favorable conditions, and 55-65 thousand plants per hectare under unfavorable conditions. The plant exhibits medium to high anthocyanin pigmentation in various parts, including the first leaf sheath and roots, which may indicate its resistance. In field conditions, the hybrid is moderately affected by ear Fusarium, requiring attention during agronomic practices. Overall, KWS 2322 is a reliable and productive corn hybrid suitable for cultivation in the Central Chernozem region with the potential to achieve high yields with proper care.
