A study led by the University of Alberta in Canada has found that growing perennial cereal and leguminous crops together in the same field can increase yields and plant resistance. The research, published in the Journal of Animal Science, demonstrates that this approach maximizes the potential of both types of crops and can reduce farmers' reliance on synthetic fertilizers. The study, which involved planting two perennial grasses and three legumes at six sites across the province, found that the combined crops had a positive impact on forage yield and nutritional value.
