The 2025 growing season provided another great opportunity to evaluate both silage hybrids and winter cereals for forage use under North Dakota conditions. Results from irrigated and dryland silage trials, along with winter rye forage data, assist producers in identify high-performing varieties that balance yield and nutritional quality.
Irrigated and Dryland Silage Performance
Under irrigation, three Integra hybrids (STP4723, STP5191, and STP5203) averaged 25.4 tons per acre (dry matter basis), with harvest moisture near 61%. Yields ranged from 23.6 to 25.4 tons per acre, reflecting consistent performance across hybrids. STP5191 showed the highest yield, suggesting strong silage potential under irrigated conditions.
Dryland trials included seven hybrids from Integra, Proseed, and Golden Harvest. Yields ranged from 23.9 to 29.8 tons per acre, with an overall mean of 27.3 tons per acre. The Integra STP5191 again led the group, producing 29.8 tons per acre, followed closely by Proseed LFY101 and STS105GT. Despite slightly lower plant height under dryland conditions, yield stability across entries was excellent, demonstrating the resilience of modern silage hybrids even under limited moisture.
