To determine if two crop species sown together (intercropping) could provide an opportunity to increase total grain yield compared to monocultures, diversify grain production and increase yield and profit in the Riverine Plains region.
• Four dual-species mixes (field pea/canola, faba bean/canola, faba bean/wheat and barley/canola) were sown at different ratios at Rutherglen, Burramine and Caniambo during 2020.
• At all three sites, seasonal conditions during 2020 were exceptional, with excellent growing season rainfall (GSR) resulting in high yields across the trials.
• At the Rutherglen site, all the dual-species combinations resulted in positive yield benefits compared with the monoculture crops.
• At the Burramine and Caniambo sites, 75% of the dual-species combinations resulted in positive yield benefits compared with the monoculture crops.
• To achieve a superior economic return, when compared to a monoculture of either species, the intercrop land equivalent ration (LER) needed to be greater than 1.1.
