In shifting cultivation, the shifting cycle has been shrunk to about 5 years or even below 5 years, mainly due to
Shifting cultivation is mainly practiced in north eastern region, it is a primitive type of system where land instead of crops are rotated, cultivation on a particular piece of land was done till it worn out. Due to increase in Tribal population the shifting cycle has been shrunk and land rotation is frequent
