Analysis of Trends and Instability in Area, Production and Productivity of Indian Coffee

This paper attempts to estimate trends in area, production and productivity of Arabica and Robusta coffee for the period of 1995-96 to 2011-12. The analysis is based on data for past 17 years. The entire analysis was done separately for all coffee growing states for the study. The trend in growth analysis reveals that the trend in area, production and productivity over the years were positive in first and third period and while in the second period, was shown negative as indicated by the cubic equation. The study also noticed that the trend of Robusta with respect to area and production surpassed Arabica at national level. Further, as the crop was introduced in the last decades in to non-traditional areas in a bigger way, the instability with respect to both Arabica and Robusta was very high and hence, affecting on stability at national figures. The main sources of instability in coffee production (Arabica and Robusta) were found to be changed in area variance and changed in yield variance.
