Explanation:

- Crop rotation: This involves growing different types of crops in the same field across different seasons or years to maintain soil health and reduce pest buildup.

- Inter cropping: This is the cultivation of two or more crops in the same field with each crop in separate rows. It maximizes space and can enhance biomass and yield.

- Alternate cropping: This is the growing of alternative crops to diversify production but not necessarily providing spatial separation like in intercropping.

- Kharif cropping: This refers to crops that are sown with the onset of the monsoon and harvested in autumn in South Asia. It is a seasonal term, unrelated to the technique of growing crops in different rows.
