How do oat–pea intercropping and reduced nitrogen fertility affect crop performance and economics? This report shares results from the 2025 Northern Plains Program demonstration trial at the Northeast Agriculture Research Foundation (NARF) near Melfort, Saskatchewan. The trial compared oat monocrops and oat–pea intercrops under varying nitrogen rates, examining yield, grain quality, nitrogen-use efficiency and economics.
Explore the results to see how reducing nitrogen affected oat production, how intercropping influenced oat and pea yields, and the potential economic and longer-term rotational and soil-health considerations of each system.
Read the full report to learn what we discovered and what these results could mean for producers considering reduced nitrogen or intercropping on their farms.
