India has the world's highest concentration of tribal people (8.2%), with the North East area accounting for 8.55% of the tribal population of India. Of the seven states in Northeast India, in four states the majority of the population is tribal: Mizoram (94.5%), Nagaland (89.1%), Meghalaya (84.9%), and Arunachal Pradesh (64.2%). Further, even after continuous efforts of extension organisations, 60% of the farmers do not access any source of information for advanced agricultural technological information, resulting in a huge adoption gap. To tackle this issue, understanding the most efficient source of information transfer in the aforementioned region is imperative. In light of the above facts, this comprehensive review has been conducted focusing on the dissemination of knowledge, adoption of innovative practices, and empowerment of local communities. The key insight drawn from this study was that in Assam 75% of the agricultural information was mainly transferred through television. Similarly, in Mizoram and Manipur agricultural information was transferred to the tribal community through television in the tune of 50.91% and 63.64% respectively. On the other hand in Meghalaya(71.60%) and Tripura(78.75%), mobile phone was found to be the most impactful medium for information transfer. Therefore, it can be safely concluded that mobile and television were two major sources of information transfer in Northeast India.
