Variety description

10 August 2026

The hybrid Kneja 625 is a highly productive agricultural crop bred at the Maize Research Institute in the city of Kneja. It was traditionally developed for the needs of grain production.

During scientific research of the hybrid, its morphological indicators were studied, including ear length and thickness, as well as the number of grain rows. Field trials of yield at different planting densities from 4500 to 6500 plants per decare were also conducted, and correlation links with leaf area were analyzed.

The hybrid trials were conducted under non-irrigated field conditions.
