Intercropping grain pea with cereals in organic farming

Intercropping grain peas with cereals like barley, rye, or triticale is a proven method in Swiss organic farming. This system enhances resilience to biotic and abiotic stresses through semi-leafless peas and optional camelina. Key practices include seed pre-mixing, proper sowing depth, and adjustable seed ratios. Success depends on crop rotation, seedbed prep, timing, weed control, fertilisation, and post-harvest separation. Widely adopted in Swiss organic grain pea production.
