Abstract
Millets are an important group of food grains. Understanding the sources of growth is crucial for enhancing the performance of millets under rainfed condition. This study examines the contribution of area effect, yield effect and interaction effect to the production growth performance of Cholam, Cumbu, Ragi, Thinai and Samai using Decomposition Analysis across two decades and the overall period. Decomposition results indicated shifting drivers of growth Cholamâs production was influenced by interaction, area and yield across periods; Cumbu and Ragi became more yield-driven indicating improved cultivation practices; Thinai relied mainly on yield gains; and Samai shifted from area to yield effects. Overall, the findings emphasize the need to strengthen yield enhancing technologies to ensure sustainable growth in millet production.
