Over the past four decades, India’s cropping pattern has experienced profound structural changes, with crop diversification emerging as a defining feature. These transformations, spanning the period 1980–81 to 2023–24, have been driven by a combination of economic reforms, climatic variability, technological advancements, and policy interventions. A marked shift has occurred from a cereal-centric production system toward a more diversified agricultural base that increasingly includes horticultural crops, pulses, oilseeds, and other commercial crops. The study highlights the role of government initiatives, innovations in agricultural technology, and changing climatic conditions in shaping these dynamics. To investigate the determinants of diversification, explanatory variables such as percentage of irrigated area (PIA), road density (RD), agricultural credit (AC), and fertilizer use per hectare (FUPH) are examined. These infrastructural and technological factors together explain the evolving trajectory of cropping patterns across India.
