Groundnut, an oilseed derived from the fruit of groundnut plant. It is commonly mistaken as a nut though it is not a nut exactly; it’s a seed rather and is also known by the name of peanut. The main objective of the study is to explore the influence of farming and technological antecedents on extraction of groundnut oil in Tumakuru district. Descriptive research methodology was followed to attain the framed objective; the required primary data have been collected from 240 groundnuts farmers and also who involved in groundnut oil extraction process by using convenient sampling technique. In Tumakuru District, the required primary data have been collected by using a well-structured and pre- tested interview schedule Such collected data have been analysed with regression analysis. It is found that, the unique contribution of the variables related to farming factors such as Sophisticated farming knowledge, growing only under contract, Season specific plans, Resource availability, Choice of an appropriate market channel, and Irrigation facilities have found significant influence factors in predicting the extraction of groundnut oil in Tumakuru district. is accepted. The unique contribution of the variables related to technological factors such as Physical Squeezing, Cold-Pressing Technology, Application of Pressure, Hydraulic Jacks, Plate Presses, and Rams Press have a significant relationship with the extraction of groundnut oil in Tumakuru district.
