The careful practice of Intercropping and crop rotation can help in __:
1. greater yield per area of land
2. encouragement to biodiversity
3. pesticide control
Select the correct option from the codes given below:

Answer: [D] 1, 2 & 3

lntercropping is the practice of growing different crops in the same field. There are many spatial combinations possible for intercropping, including mixed intercropping, in which different crops are planted in the same row or without regard to row, and row intercropping, which involves planting different crops in alternating rows.

Crop rotation involves planting different crops on the same plot during different times of the year, and can include some of the benefits of intercropping, such as reducing insect pest populations, increasing beneficial insects, and weed suppression. In addition, non-crop plants such as weeds, cover crops, and habitat plantings can be combined in space and time to influence numbers of pest and beneficial arthropods on the main crop.
