<br/><br/> Soybean (Glycine max (L.) Merrill) is a major oilseed crop and is known as 'Golden bean' and 'Miracle crop'. A multistage purposive sampling technique was employed for selection of 128 sample respondents who were cultivating soybean from Belagavi and Dharwad districts for the crop year 2021-22. The secondary data was collected from various published sources. The growth in area, production and productivity of soybean in selected districts of Karnataka and India and their instability as measured by Compound Annual Growth Rate (CAGR) and Cuddy-Della Valle Instability index (CDVI), respectively, was estimated for a period of 20 years from 1999-2000 to 2018-19. The entire study period was divided into two sub-periods viz., period I (1999-00 to 2008-09) and period II (2009-10 to 2018-19). The results revealed that soybean is a major kharif crop in study area which occupied about 21.38 percent, 17.21 percent and 18.95 percent of the gross cropped area in Dharwad, Belagavi and the study area as a whole among sample respondents. In Karnataka, area under soybean registered a signicant and positive growth during period I (11.74%), period II (6.36%) and overall period (9.17%) with instability indices of 25.16 percent, 12.54 percent and 18.43 percent, respectively. Likewise, the production of soybean recorded a signicant positive growth rate during period I (8.53%), period II (9.26%) and overall period (10.17%) with instability indices of 23.50 percent, 22.91 percent and 23.16 percent, respectively. However, the productivity of soybean registered non-signicant growth during all the study periods.- Reproduced <br/><br/>https://desagri.gov.in/wp-content/uploads/2023/08/ASI-Jan-2023-Final-copy.pdf<br/>
