Inter-sow refers to the act of sowing or planting seeds between previously established crops. This practice is often used to maximize land usage, increase productivity and promote sustainable farming. Some synonyms for inter-sow include, intercropping, relay cropping, sequential cropping, and crop rotation. Intercropping allows a farmer to plant different crops together in the same field, for instance, growing legumes with cereal crops in a single farmer's field. Relay cropping involves planting short season crops after others have been harvested. Sequential cropping refers to planting different crops in the same field in successive seasons, while crop rotation involves alternating the type of crop grown in each field every season to manage soil fertility and control pests.
