Rice region

Rice is considered as the major crop in the vast region stretching from lower Gangetic plain to Brahmaputra valley in the east and the circum-coastal alluvial tracts of the peninsula region. Though rice displays overall dominance, considering the secondary importance of other crops, this region may be subdivided into following zones:

• Rice-Jute-Tea: This association of crops occurs in far east, near Assam Valley, north-west Bengal and lower Gangetic plains.

• Rice-Pulses-Millets-: This association occurs in the western section of the former zone, covering central Bihar, eastern Madhya Pradesh and eastern Uttar Pradesh.

• Rice-Millets: This zone comprises the entire Andhra Pradesh, southern Orissa and some parts of Tamil Nadu.

• Rice-Coffee-Spices: This zone is found in the southern extremity of Kerala and Tamil Nadu.
