Option 1: Mixed cropping refers to the practice of growing two or more crops together in the same field without any specific pattern. This method is commonly used to maximize the use of space and increase crop diversity.

Option 2: Inter cropping is the correct answer. It involves the simultaneous cultivation of two or more crops in a specific pattern or sequence on the same field. The aim is to optimize the utilization of resources such as sunlight, water, and nutrients. Inter cropping helps in reducing the risk of crop failure and increasing overall productivity.

Option 3: Mixed farming, on the other hand, refers to the practice of combining multiple agricultural activities like crop cultivation, livestock rearing, and poultry farming on the same farm. It is a form of diversification that helps in balancing income sources and reducing risks.

Option 4: Hybrid farming is not the correct term for the simultaneous cultivation of multiple crops in a definite pattern. Hybrid farming generally refers to the practice of producing hybrid varieties of crops through controlled breeding techniques.

In conclusion, the correct term for the growing of two or more crops simultaneously on the same field in a definite pattern is inter cropping.
