This study examines growth trends of mustard in respect of area, production and productivity at Bharatpur district. Study is based entirely upon secondary data for the period of 27 years (1990-91 to 2016-17). To estimate compound growth rate of area, production and productivity exponential function has been applied. Instead of that coefficient of variation is computed to get variation around the mean and instability index is also computed to get variation around the trend. The contribution of area and productivity in production of mustard is expressed through decomposition analysis. The result indicated that growth rates of mustard in case of area, production and productivity were positive for the overall period. Growth rates were statistically significant and positive in case of production and productivity in mentioned period. Instability index shows highest variation around trend in production of mustard. Coefficient of variation was also found to be highest in case of production in mustard followed by productivity. Production increases because of increase in productivity under mustard in the corresponding period.

KEYWORDS: Productivity, Secondary Data, Growth Rate, Instability Index, Decomposition Analysis.
