This research examines the structural break points in rice for area, production and productivity in Assam using annual time series data spanning the years from 1990 through 2015. The structural changes occur during the sample period. Thus after applying unit root tests of Augmented Dickey–Fuller (ADF), time series properties of the data are analyzed by F statistic (chow test) approach to determine structural breaks in variables of agricultural commodities. The result from the Chow test which was formalized from Perron23 clearly indicate that on time series data on three assumed dates 1998-99, 2004-05 and 2006-07 at which there was a statistically significant structural break. The study reveals that endogenously determined structural break time for the agricultural variables (area, production, productivity) of Assam was found to be 1998-99, 2004-05 and 2006-07.

Key words: Structural break, Assam, Rice, Production.
