Answers
Rotation of crops is the process which helps to retain the fertility of the soil. The crops are grown alternatively.
ii). For example: Wheat is grown in one season and sugarcane is grown in other.
Multiple Cropping
i). Raising more than one crop on the same field during the same season is known as multiple cropping.
ii). For example: wheat and mustard.

Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients.
crop rotation It helps in reducing soil erosion and increases soil fertility and crop yield.
The technique of multiple cropping allows farmers to achieve better results by making practical use of resources such as soil, water, fertilisers, etc.
the first importance of multiple cropping is increase output area as multiple cropping involves cultivating two or more crops in same field during one season..
multiple cropping also helps maintain soil fertility with suitable crops like legumes in the cropping systems.
it also decreases space available for weeds restrict their growth by supressing weeds..it also increases food production.
crop rotation increases soil structure water conservation in soil.
crop rotation stops land water pollutions.
crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops.
Crop rotation also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted.
