Abstract:
The growth rate analysis is mainly used in economics to know the trend of a particular variable over a period of time and often used for policy analysis. The present study was attempted to examine the annual compound growth rate of area, production and yield of major maize growing districts of Odisha. The secondary data covering the period from 2003 to 2017 were collected from various issues of economic survey of Odisha for computation of growth rate and instability index. The statistical measures like exponential function and Cuddy Della Valle index were used for calculation of growth rate and instability index respectively. The study revealed that Kalahandi district registered the highest growth rate (7.4%) in area followed by Nabarangpur (4.8%), Koraput (4.2%), Rayagada (2.6%) and Keonjhar (-0.1%) districts respectively. Similarly in case of yield parameter, Keonjhar district recorded the highest growth rate (10.3%) followed by Kalahandi (10%), Rayagada (8.1%), Koraput (7.9%) and Nabarangpur (1.9%) respectively. So far as production was concerned, Kalahandi district recorded the highest growth rate in production (17%) followed by Koraput (12%), Rayagada (10.7%), Keonjhar (9.9%) and Nabarangpur (6.6%) respectively. In Odisha the annual compound growth rate of area, yield and production were reported to be 2.8%, 6.3% and 9.2% respectively. Area expansion and yield were the major factors or increased maize production in the state. Therefore, the thrust should be given to increase the area by utilizing the suitable area and to increase the yield through technological advancement, varietal research, and strengthening agro advisory services in Odisha. The computation of instability index confirmed that districts like Keonjhar and Rayagada experienced low level of instability so far as area was concerned. The districts like Nabarangpur and Koraput suffered from medium level of instability. The instability in area was found to be very high in case of Kalahandi district. The instability of yield in Odisha was observed to be low. The districts which showed low instability in yield were Koraput and Rayagada. The moderate level of instability was observed in Nabarangpur district. The instability in production for Nabarangpur, Keonjhar, Koraput, Kalahandi and Rayagada districts were reported to be 27.73, 15.90, 21.54, 55.34 and 26.93 respectively. Moderate instability in production was observed in the state as a whole.
