1. Inter-cropping: In this method, the crops are selected such that their nutrient requirements are different. This ensures maximum utilisation of nutrients supplied and also prevent pests and **** from spreading to all the plants belonging to one crop in a field. This way both crops can give better returns.
2. Crop rotation: The growing of different crops on a piece of land in a pre-planned succession is known as crop rotation. If crop rotation is done properly then two or three crops can be grown in a year with good harvest.
