and conclusion Customer satisfaction and loyalty are the ultimate outputs of any firm for sustaining competitive advantage in the market, as well as for increasing profitability. Initially, with the help of exploratory factor analysis (KMO, composite reliability and Cronbach’s alpha scores), we reduced the variables, which assisted in determining the exogenous (image, expectations, perceived quality and perceived value) and endogenous latent variables (satisfaction and loyalty) as input and output variables for the model. Following this, an output-oriented BCC DEA model was used for measuring farmers’ satisfaction and loyalty efficiency toward fertilizer brands. The results show that PPL was ranked as the preferred fertilizer brand, followed by IFFCO and CIL, whereas IPL and TCL were the least-preferred brands. As stated earlier, Odisha is a proactive agrarian state, with a number of agricultural input companies operating in different input marketing sectors, like fertilizer, seeds, equipment and crop protection chemicals, with steep competition for gaining and maintaining a high market share. Therefore, this study will help to make them aware of the different vital reasons for their growth and the actions required to keep the farmers highly satisfied because it is more expensive to attract new farmers than to retain existing farmers. For the older firms in the market, it is important to improve their images and accord farmers’ expectations the utmost priority. The existing firms must put in all efforts and must look to provide good services and high-quality products with timely delivery, which will lead to farmers’ satisfaction and, over a period of time, enhanced overall loyalty.
