ethodological approaches for delineating the sources of Agricultural growth

In India, agriculture remains a cornerstone of the economy, providing livelihood for over half the population and ensuring national food security, despite a notable structural shift towards industry and services. Technological advancements, such as the Green Revolution, alongside policy support and infrastructure investments, have boosted agricultural productivity. However, the sector's share of GDP has decreased from 33 per cent in the 1980s to 18 per cent in 2023. This study delves into various decomposition models to analyze agricultural growth, including methodologies developed by Minhas and Vaidyanathan, Hazell, Bisaliah and Total Factor Productivity (TFP). These models help identify key growth factors and productivity sources, offering insights into agricultural performance and guiding policies for sectoral development.
