Plantation crops such as premium coffee, cardamom, and tea are grown in hilly areas in small quantities with large growth potential. Most people cultivate rice as it is the main staple diet of the people. About 80% of the cropped area is dedicated to rice. Oilseeds is another, higher income crop gaining ground in Nagaland. The farm productivity for all crops is low, compared to other Indian states, suggesting a significant opportunity for farmer income increase. Currently, the Jhum to Terraced cultivation ratio is 4:3; where Jhum is the local name for cut-and-burn shift farming. Jhum farming is ancient, causes a lot of pollution and soil damage, yet accounts for the majority of the farmed area. The state does not produce enough food and depends on the trade of food from other states of India.
