Question:

What are the advantages of inter-cropping and crop rotation?

Answer:

Inter-cropping and crop rotation both play an important role in increasing the yield of crops. Inter-cropping helps to maintain soil fertility and prevents pests and diseases from spreading throughout the field. It increases productivity per unit area. Crop rotation improves the soil fertility and avoids depletion of a particular nutrient. It minimizes the pest infestation and diseases. Both these methods reduce the need for fertilizers. It also helps in controlling weeds and controls the growth of pathogens and pests in crops.
