Intercropping systems in Arunachal Pradesh aim to:

The correct answer is: All of the above.

Intercropping is a cropping system in which two or more crops are grown simultaneously on the same piece of land. It is a traditional practice in many parts of the world, including Arunachal Pradesh. Intercropping has many benefits, including:

• Maximizing land use: Intercropping can help to increase crop yields by using land more efficiently. For example, intercropping a legume with a cereal can help to improve soil nitrogen levels, which can lead to higher yields of the cereal.
• Improving soil fertility: Intercropping can help to improve soil fertility by providing a source of organic matter and nutrients. For example, intercropping a legume with a cereal can help to fix nitrogen from the atmosphere, which can be used by the cereal.
• Controlling pests: Intercropping can help to control pests by disrupting their life cycles. For example, intercropping a cereal with a legume can help to reduce the incidence of cereal pests, as the legumes provide a refuge for natural enemies of the pests.

In addition to these benefits, intercropping can also help to reduce soil erosion, improve water infiltration, and increase biodiversity. It is a sustainable agricultural practice that can help to improve food security and reduce environmental degradation.
