The correct answer is: Rice followed by vegetables.
Crop rotation is a system of farming where different types of crops are grown in the same field in a planned sequence. This helps to improve soil fertility and reduce the risk of pests and diseases.
In Manipur, a common crop rotation practice is to grow rice followed by vegetables. Rice is a major crop in Manipur, and it is grown in both wet and dry fields. Vegetables are also a major crop in Manipur, and they are grown in both wet and dry fields.
Rice is a heavy feeder, and it takes a lot of nutrients from the soil. Growing vegetables after rice helps to replenish the nutrients in the soil. Vegetables are also a good source of nitrogen, which is an important nutrient for rice.
Crop rotation also helps to reduce the risk of pests and diseases. Pests and diseases can build up in the soil over time, and they can attack crops if they are grown in the same field year after year. Crop rotation helps to break the cycle of pests and diseases by growing different types of crops in the same field.
Maize followed by pulses, millets followed by oilseeds, and fruits followed by fallow are also common crop rotation practices in Manipur. However, rice followed by vegetables is the most common practice.
