The trust areas of KVKs are refinement and demonstration of technologies, and training of farmers and extension functionaries. Imparting vocational trainings in agriculture and allied fields for the rural youth is one of its mandates. The study was undertaken to do a formative and summative (outcome and impact) evaluation of the Dairy farming and mushroom growing vocational training programmes in the Jaisalmer District of Rajasthan state. One-group pre and post evaluation design was employed for conducting a formative and outcome evaluation. The knowledge tests were administered to 40 Dairy farming and 40 mushroom cultivation trainees, before and after the training programmes organized in 2020 to 2021. The vocational training programmes have resulted in continued-adoption of Dairy farming and mushroom cultivation enterprises by 51 % and 20 % trained farmers, respectively. Age and trainee occupation had significant influence on the adoption decision of Dairy farming vocation, whereas education and family income significantly affected the adoption decision of mushroom cultivation. The continued adapters of Dairy farming and mushroom growing had increased their family income by 49% and 24%, respectively. These training programmes are augmenting the dwindling farm income of the farmers in Jaisalmer District of Rajasthan.
