Cereal grains viz., Wheat, rice, and maize are stapled foods across the globe. Given this, the goal of the current study was to estimate the growth in acreage, output, yield, and decomposition analysis of the state’s principal cereal crops. For the period of 30 years, from 1991-1992 to 2020-2021, the secondary data were gathered from the DES, New Delhi, Agricultural statistics yearly data book, etc. These decades were broken further into four sections: Decade I (1991-2000), Decade II (2001-2010), Decade III (2011-2020), and

overall (1991-2020). The annual growth rates and proportional contributions of components in the grain harvest output were quantified using exponential trend and decomposition model. The study examined that the growth rate for wheat reported positive, whereas rice and maize show mixed patterns. Rice was one of the crops which reported affirmative and significantly favorable growth at the value of 0.46 per cent throughout the entire study period. Decomposition analysis of wheat, rice, and maize revealed that the rise in output was caused by the yield effect, although the acreage effect for rice and maize was significant and positive for decade II.

Highlights

• The growth rates showed mixed patterns during the study period.
• Yield effects were superior for wheat, rice, and maize.
