In Hungary for the most part of the arable land were one-crop plant productions, which means mostly corn, wheat, barley, sunflower and autumn rape. This overproduction were increased the number of fodder need animals and protein requirement, which we couldn’t be able to fulfill only from national production. Filed pea has the highest yield of leguminous plants in the whole world. In spite of the continously growing demand of protein plant and excellent properties the sown area of field pea is very small in this region. Intercrop is a possible way to increase the sown area and diversificate plants to cultivating two or more simultaneously in the same field: sowing, take care and harvest together. The research was established in one growing season (2019/2020), with 2 winter wheat species (GK Szilárd, Cellule) and one filed pea species (Aviron), in 4 repeats, on 10 square meter random layout plots in the research site in Szeged-Öthalom. We use 2 different seed density in every species in every combination, and compared grain yield and inner content values of the mixed parcels with the control and fertilized plots. The grain yield of mixed wheat-pea stands is generally small, but in two cases we observed higher grain yield than the control plot, what we couldn’t prove it statistically. In addition inner content values (crude protein, gluten, zeleny) were still the same level. There were no differences between wheat pure stands and plant associations statistically. The highest values without exception were winter wheat with fertilizer plots. However the most preferred plant association- because of their inner content- were the Aviron 100 seed-2 with both winter wheat species.Our aim is to evolve an alternative technology for farmers how to produce by low input and high yield stability. Pea-wheat intercropping is a promising way to produce cereal grains in an efficient, economically sustainable and environmentally friendly way.
