Abstract: This paper has studied the growth trends and decomposition analysis of area, production and productivity of groundnut in Gujarat. The study was based on the secondary data of 20 years from 1996-97 to 2015-16 which was split into two sub-periods i.e. period I 1996-97 to 2005-06 and period II 2006-07 to 2015-16. The growth rates were calculated by exponential function and instability by Coefficient of variation and Cuddy Della Valle’s instability index. The relative contribution of area and yield to change in output was estimated by using Minhas decomposition model. The result showed that, the compound growth rate for area, production and productivity during period I was positive. The instability indices i.e. CV and CDVI were lowest during all the periods in case of area. For area, production and productivity the cubic function was best fitted while the decomposition analysis showed largest area effect on groundnut production during overall period.
