The data were recorded for five major groundnut growing districts viz. Amreli, Bhavnagar, Jamnagar, Junagadh and Rajkot and for the state as a whole. An attempt was made in present investigation to fit polynomial and ARIMA models to arrive at a methodology that can precisely explain the fluctuation in area, production and productivity for groundnut crop in different districts of Gujarat state and to compare different modelsenAgricultural StatisticsStatisticsThesis
