Intercropping is a type of multiple cropping system in which two or more crops are grown simultaneously on the same field. Relay intercropping is the production of a second crop planted into a field when the first crop has reached its reproductive stage but before physiological maturity. 2025/6/17 Prof.Dr.LiL 2

2025/6/17 Prof. Dr. Li L 3 Intercropping includes • Strip intercropping: growing two or more crops in strips wide enough to allow independent cultivation and yet narrow enough to induce crop interactions • Row intercropping: growing two or more crops in a well-defined row arrange-ment • Mixed intercropping: growing two or more crops in an irregular arrangement • Relay intercropping: planting one or more crops within an established crop so that the final stage of the first crop coincides with the initial stage of the next crop
