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
