Careful identification of target groups is essential in any effective agricultural extension program. Since one of the objectives of agricultural extension is to increase crop yield, efforts should be exerted to clearly identify the target audience. Blanket recommendations have given marginal returns to investments. In this context, the farmer performance index (FPI) can be used to categorize farmers who can be targeted as recipients of extension programs. Pingali et al (1990) have defined FPI as the ratio of farmers’ actual yield to location-specific yield (LSY) potential. The main advantage of using FPI in agricultural extension programs is the assurance that extension targets can be identified for different technological packages.
