Rice cultivation is concentrated in 5 districts of Mizoram. Out of which one district falls under medium productivity group, 3 districts are under medium-low productivity group and one district comes under low productivity group. Triennium average area of medium productivity group (yield 2,000-2,500 kg/ha) in one district was 0.173 lakh hectares, which was 32.3% of triennium average area (0.536 lakh hectares) under rice in the State. Triennium average production was 0.349 lakh tonnes, which was 37.4% of triennium average production (0.933 lakh tonnes) of rice in the State. Triennium average productivity of medium productivity group in one district was 2,017 kg/ha as against 1,741 kg/ha triennium average productivity of the State.

Triennium average area of medium-low productivity (yield 1,500-2,000 kg/ha) comprising of three districts was 0.299 lakh hectares, which was 55.8% of triennium average area (0.536 lakh hectares) under rice in the State. Triennium average production was 0.493 lakh tonnes, which was 52.8% of triennium average production (0.933 lakh tonnes) of rice in the State. Triennium average productivity of medium-low productivity group comprising of three districts was 1,649 kg/ha as against 1,741 kg/ha, triennium average productivity of the State.

Triennium average area of low productivity group (yield 1,000-1,500 kg/ha) in one district was 0.064 lakh hectares, which was 11.9% of triennium average area (0.536 lakh hectares) under rice in the State. Triennium average production was 0.091 lakh tonnes, which was 9.8% of triennium average production (0.933 lakh tonnes) of rice in the State. Triennium average productivity of low productivity group in one district was 1,422 kg/ha as against 1,741 kg/ha triennium average productivity of the State.

Nearly 56% of total area under rice in the State is concentrated in medium-low productivity group, which accounts for about 53% of total rice production in the State. High productivity zone does not exist in Mizoram. Triennium average productivity of the State is 1,741 kg/ha, which is about 11% less than the national triennium average productivity of 1,947 kg/ha. Low productivity is attributed due to adoption of old traditional varieties and lack of irrigation facilities. Area covered under high yielding varieties is nearly 10% and area covered under irrigation is about 8% in the State.

Area, production and productivity of rice under different productivity groups in Mizoram during triennium ending 2000-2001 are given in Table-16.
