What are the different croping patern …

Cropping pattern means the proportion of area under various crops at a point of time. This is, however, a dynamic concept as it changes over space and time
There are three distinct crop seasons in the northern and interior parts of country, namely kharif, rabi, and zaid.
crops can be  identified as associating themselves with a particular type of agro-climate, and certain other minor crops with similar requirements are grouped in one category. For example, wheat, barley and oats, are taken as one category.
Certain other crops, such as the plantation crops and other industrial crops are discussed separately. Among the kharif crops, rice, jowar, bajra, maize, groundnut and cotton are the prominent crops to be considered the base crops for describing the kharif cropping patterns.
Among the rabi crops, wheat, gram and sorghum or jowar are considered the base crops for explaining the rabi cropping pattern.
