摘要：Adoption assessment and quantification of returns to investment of soil-water-nutrient management research outputs received little attention in the literature. This paper attempted to estimate the adoption and measure impact of the research information related to soil-water-nutrient management. A specific case, the Groundnut Production Technology, was selected. The study finds that farmers adopt concept and modify the package as per their needs, convenience and resource endowments. It was found that there was differential adoption of various components of the Groundnut Production Technology package. The adoption of various components related to nutrient management was ranging from 10% for ferrous sulphate, to 35% gypsum, and 50% single super phosphate. Adoption of soil management component was in about 29% groundnut area. Water management through sprinkler irrigation was adopted in about 11% area. Farm-level benefits were realized in terms of yield gains, higher income, better output prices, efficient utilization of inputs, etc. The benefits were quite higher than t.he research and packaging cost of the Groundnut Production Technology. Investment on extension of the technology to cover more area may be very rewarding.
