The farmer ’s exposure to risk and uncertainty is often provoked by lack of information about inputs, farm management practices or market prices and this lack of information has an adverse impact on crop production and income. The evidences suggested that a farmer who received quality, up-to-date information and who has the ability to use that information is able to lessen the effect of these risks. To minimize all types of risks of farmers, there are number of ICT initiatives working in the country. However escalating large number of ICT projects in country, are unable to fill the information gap. mKRISHI® system of disseminating messages in agriculture technology is an important extension methodology in this ICT era. Beside its wide adaptability among the farmers, it has few limitations to meet the information needs of all the farmers. Hence the present study was conducted in the Nasik and Kanchipuram districts of Maharashtra and Tamil Nadu respectively where mKRISHI® is working with the objective to analyze the various constraints in providing the extension services through the use of messages. A sample of 60 beneficiary farmers from both the districts was selected. An open-ended questionnaire was used to obtain the perception of the farmers about the constraints. Garrette ranking technique was used to rank the constraints. Later a structured schedule was also used to collect information related to the constraints. Friedman test was used to identify the most severe constraints. It was found that the most severe constraint in the functioning of mKRISHI® was Lack of update information followed by High cost for service provided,low IT literacy and low literacy
