An analysis of growth and variability in area, production and yield of groundnut in Punjab

The study was conducted to examine the trends and variability in the growth of groundnut as oilseed crop in Punjab state. For the analysis purpose, the relevant secondary data from 1975–76 to 2014–15 were examined. The study was based upon secondary time series data collected from issues of various statistica. abstracts of Punjab, published by Government of India or Economic and Statistical Organisation. The compound growth rates were estimated with the help of exponential function and variability by using Cuddy-Della Vella test for the convenience of comparison over the period. Therefore it was subdivided into three periods [Period-I: 1975–1995 (pre-WTO), Period-II: 1996–2015 (post-WTO) and whole period: 1975–2015]. The study concluded that area and yield had declined but reciprocated in terms of production in the whole study period. In context with variability, the study concluded that there persisted wide fluctuations in the growth of area and production of groundnut over the study period.
