      The study is based on secondary data collected from various publications for the period 1990-91 to 2010-11. The performance of paddy crop in different districts of Eastern Vidarbha region is studied by estimating growth rates of area, production and productivity using “Exponential function”. Co-efficient of variation and Coppock’s Instability Index has been computed to measure the degree of instability in productivity of rice. Similarly, Nerlovian lagged adjustment model is estimated to know the various factors affecting the acreage planted under the rice crop.

       In case of area under paddy for the period-I (1990-91 to 2000- 01) and period-II (2001-02 to 2010-2011) almost all districts shows nonsignificant growth except for Gadchiroli district where very low and positive growth was observed. The growth in paddy production was negative and non-significant in almost all districts for different periods except for Chandrapur district for period-II where significant negative growth was observed. Similar picture of negative and non-significant growth was obsersved in case of productivity of paddy except for Chandrapur and Eastern Vidarbha for period-II where significant negative growth were observed. The variability in area of paddy was highest in Chandrapur and lowest in Gadchiroli District. Eastern Vidarbha as a whole has observed constant variability; it means that the area under paddy is stagnant. In general Eastern Vidarbha has shown cosntant instability in area for different periods. Chandrapur and Bhandara districts shows high variability in the production of paddy for various time period. Similarly, Bhandara districts has observed the highest Coppock’s instability index for period-I. 

       In case of productivity lowest variability was observed in Bhandara district for period-II. In general it is observed that variability and instability was found lower in period-II in all districts as compare to periodI. In acreage response model, lagged year price of paddy and gross irrigated area were found positively significant for Bhandara district for overall period of study. In cast of Chandrapur district lagged year area found negatively significant i.e. lagged year area is negatively affecting the acreage allocation of paddy. However, in Gadchiroli district, lagged year price and price risk were positive and significant impact on acreage allocation of paddy

       In forgoing analysis for overall period area, production and productivity of has shown non-significant growth. For acreage allocation of rice, lagged year price, lagged year area, gross irrigated area, and price risk has significant effect.
