Abstract:

Agricultural growth with stability has been a matter of concern in Odisha. As rice is the major crop growing in the state, the present study was therefore carried out with the objectives to work out the district wise growth rate of area, production and yield of rice and to estimate district wise instability in area, production and yield of rice in districts of Odisha. The study was based on the secondary data on area, production and yield of rice in Odisha state collected from different sources like Directorate of Agriculture and Farmers Welfare, Directorate of Economics and Statistics, Department of Agriculture & Farmers’ Empowerment, Government of Odisha and other departments. The data under study for all district of Odisha from 1993-94 to 2016-17 was split into four periods i.e. period I: 1993-94 to1999-2000, period II: 2001-02 to 2009-10, period III: 2011-2012 to 2016-17 and period IV: 1993-94 to 2016-17. The growth rates for area, production and yield were computed using exponential model. The instability in area, production and productivity was measured through Cuddy Della Valle’s instability index was used to analyze the instability in area, production and yield of districts of Odisha. The compound growth rate for production was significant and highest for Deogarh district during period III. Compound growth rate for area for all the periods including overall period, shows a negative growth rate. But growth rate in case of area was highest during period I in Puri district. Lowest growth rate in area during period I was found in Ganjam district. The compound growth rate for production and yield showed positive growth rate in the entire periods except for period I. The highest Cuddy Della Valle’s instability index for area was observed in Ganjam during period I. The highest instability index for production and productivity was observed Bolangir district during period III. The instability in case of area, production and yield was highest during the period III. The growth in area was negative during all the four periods and the growth in production is mainly due to growth in yield.
