The traditional practice of shifting cultivation (jhum) in Manipur often involves growing mixed crops (rice, millets, vegetables). This is because jhum cultivation is a sustainable agricultural practice that helps to maintain the fertility of the soil. By growing a variety of crops, farmers can ensure that the soil is not depleted of any one nutrient. Additionally, mixed cropping helps to control pests and diseases.
Single crop monocultures are not sustainable because they deplete the soil of nutrients and make it more susceptible to pests and diseases. Cash crops like ginger and turmeric are not typically grown in jhum cultivation because they require more intensive farming methods. Plantation crops like tea and coffee are also not typically grown in jhum cultivation because they require large areas of land and a lot of investment.
