The study intended to analyse the farmers’ access to various agricultural extension service providers, and their preferences and thereby, delineate the underlying determinants for accessing the specific information source, using the dataset of NSSO 77th round. The study used survey data from 14,782 households of 5 major states of the Indo-Gangetic Plains (IGP) of India (Bihar, Haryana, Punjab, Uttar Pradesh and West Bengal). The preferences of the farmers ranged from private agencies, mainly the input dealers as the most preferred, followed by the traditional mass media channels and public extension system. The utility of the Cooperative model and farmer-based organisations have not yet been fully explored by the farmers for their information needs. Though multiple sources of information are available in present times, a meagre proportion of the farming population takes benefit of the same to make their decisions, a habit which should be developed and encouraged among the farmers to become well-informed and make efficient farm decisions. The inputs (seeds, fertilisers, plant protection chemicals) were the most sought-after information. However, in an era of changing needs, the farmers should try to gain more information on aspects of marketing, climate change, and post-harvest functions. Also, the extension component in the livestock sector and animal enterprises needs to be strengthened, which is more remunerative. The multivariate probit analysis reported that the likelihood of access to agricultural information sources is positively influenced by the age, gender, education level of the household head, size of operational landholding, irrigated area, and households that sold crop produce at MSP. The study suggests making the extension services for small and marginal farmers more inclusive.
