In this study, productivity, yield, and area covered under irrigation of the groundnut crop are the main emphasis areas, as it investigates the relationship between irrigation and groundnut production outcomes in India from 1950–51 to 2020–21. We estimated the average annual growth rate of groundnut productivity (yield) over the given period via the compound annual growth rate (CAGR). The calculated CAGR of approximately 2.49% indicates a positive and steady growth trajectory in groundnut output over the examined period. Regression analysis was used to examine the impact of irrigation on groundnut production via secondary data from government sources. According to the results, there is a strong positive association between groundnut production and irrigation, with irrigation levels accounting for approximately 50.3% of the production variance. The shade analysis performed in this study revealed patterns such as increasing irrigation coverage over time along with a steady increase in groundnut production over time. A 2020 study by Narayanamoorthy et al. revealed the groundbreaking effects of drip irrigation on groundnut production. The results of their research revealed that the use of flood irrigation techniques resulted in a large increase of 79% in groundnut yield and a remarkable decrease of 36% in water use. Farmers were able to increase their income through the use of drip irrigation since it reduced the costs of manpower, weeding, and intercultivation while simultaneously optimizing water utilization. This is consistent with the research that we have done using secondary data. This research recommends expanding access to modern irrigation methods, including drip and sprinkler systems, for farmers. These improvements can enhance sustainable agricultural practices and increase farmers' income by decreasing the consumption of water and input costs while increasing yields. In addition, future research may focus on examining differences between regions in the use of irrigation and the social and economic impacts of better irrigation systems in areas where groundnuts grow.
