Growth, Decomposition and Instability Analysis of Major Rabi Pulse Crops in Madhya Pradesh, India

Abstract

The purpose of the study was to analyze the growth, decomposition and instability in area, production and productivity of rabi pulse crops viz., gram and lentil in Madhya Pradesh. The study was based on secondary time series data. The time series data of area, production and productivity of rabi pulse crops viz., gram and lentil have been taken for 30 years from 1992-93 to 2021-22. The study period (1992-93 to 2021-22) was divided into four periods i.e. period-I (1992-93 to 2001-02), period-II (2002-03 to 2011-12), period- III (2012-13 to 2021-22) and overall period (1992-93 to 2021-22). Three different analyses were carried out in the study viz. (a) Compound annual growth rate by fitting exponential function, (b) Decomposition analysis by Minhas and Vaidyanthan, [1] model and (c) Instability analysis by Cuddy- Della Valle index. The findings of study observed that during the entire study period, the area under gram inclined at the rate of 0.32 per cent per annum while the production and productivity had significantly increased at the rate of 2.20, 1.88 per cent, respectively per annum in Madhya Pradesh. The production of gram in Madhya Pradesh might have increased due to significant growth in productivity. In the same time, the area, production and productivity of lentil recorded positive and significant growth rate at the rate of 3.07, 2.52 and 0.54 respectively, in Madhya Pradesh. During the overall period, yield effect was more responsible for the growth in gram and lentil production. The highest instability was observed in the production of gram and lentil crop during period – I, II, III and overall in the Madhya Pradesh. Highlights • The highest growth was noticed in the production of gram during period – II in Madhya Pradesh • The yield effect was most powerful instrument to increase the production of crops • The highest instability was found in the production of gram and lentil pulse crop
