What the grower thinks
“Chessum follows the ethos of how I like to grow my crops,” he says. “I don’t like to feed my crops with a lot of nitrogen and, like Nelson winter wheat, you can put in lower amounts of N and still get a usable crop in terms of protein.” Lincolnshire arable farmer, Colin Chappell.
Agronomic Characteristics
Outstanding yield security
Chessum has demonstrated strong yield performance in both treated and untreated situations, giving growers greater confidence when managing input costs.
Key trial results (% of control yield) have shown:
- 108.8% treated yield and 122% untreated yield (2023)
- 105% treated yield and 122% untreated yield (2024)
- 113% treated yield and 109% untreated yield (2025 drill trials)
This combination of yield potential and disease resistance helps deliver reliable returns, even under challenging conditions.
Disease resistance
Disease resilience is one of Chessum’s standout features.
- Septoria resistance: 7.1
- Yellow Rust resistance: 7
- Strong untreated performance
- Reduced fungicide reliance
- Improved crop security throughout the season
For growers seeking to balance productivity, sustainability and input efficiency, Chessum offers a robust disease package that protects yield potential.
Milling & baking performance
Independent testing has demonstrated excellent milling and baking characteristics.
Chessum delivers strong dough strength, high loaf volumes and above-average water absorption, providing millers and bakers with a reliable and consistent raw material. Premium performance can be achieved at lower protein levels, helping growers reduce nitrogen requirements without compromising marketability.
The smarter choice for modern farming
Chessum brings together the traits growers need most: high yield potential, strong disease resistance, premium milling quality and improved input efficiency.
