The analysis examined the growth and instability of area, production and productivity of autumn rice, winter rice and summer rice in BTAD.
Data were collected from the Joint Director of Economics and Statistics, BTC. The study used Compound Annual Growth Rate (CAGR) and the Cuddy-Della Valle Index to assess growth and instability.
Autumn rice showed positive growth in area, production and productivity in Period I, but area declined in Period II, despite continued gains in production and productivity. Over the full study period, area and production declined, while productivity increased due to greater use of HYV seeds, irrigation and fertilizers. Winter rice showed consistent growth in all aspects, except for a dip in area during Period II. Summer rice achieved growth in production and productivity across all periods, even as area declined, may be because of improved inputs. Overall, low instability across all rice types indicates stable growth. Expanding autumn and summer rice cultivation can help offset winter losses from flooding. Enhancing irrigation will also allow better use of fallow land during dry seasons, boosting total rice output.
