Polyhouse technology has become a valuable part of the concept of protected cultivation and has a great promise to increase the productivity of crops, enhance the efficiency of resource use, and alleviate the negative impact of abiotic stresses like drought, temperature variations, and unpredictable rainfall. The application of polyhouse technology has not been widely applied in various regions such as North Karnataka because of various limitations although it has proven to be beneficial. Therefore, the current research was carried out to critically examine the barriers to its adoption by farmers. This study was done in the selected districts in North Karnataka using a sample of 80 polyhouse farmers who were selected using a multistage sampling method. Structured interview schedule was used to gather data and limitations were classified under technical, environmental, economic, labour, marketing and miscellaneous. Mean Percent Score (MPS) and ranking were the methods to measure the severity of constraints. The findings indicated that technical reasons were the most common with poor knowledge about polyhouse crop management first (MPS: 89.20). High perishability of produce (MPS: 88.60) was the major reason of environmental constraints. The most serious in general were economic, high capital investment in the polyhouse setup (MPS: 93.40) came first in the list of the constraints. The labour related factors like high wages (MPS: 81.75) and shortage of labour were also important. Lack of assured market and stable pricing (MPS: 78.85) was found to be the greatest constraint in terms of marketing whereas lack of knowledge on processing and value addition (MPS: 91.30) dominated the miscellaneous category. The paper arrives at the conclusion that the key barriers to adoption are the economic and knowledge-based ones. These require to be tackled by means of financial support, capacity building, better infrastructure and better market connectivity so as to help to increase the adoption and sustainability of polyhouse technology in North Karnataka.
