An On-Farm Trial aims at testing a new technology or an idea in farmer’s fields, under farmers’ conditions and management, by using farmer’s own practice as control. The programme aims at testing new technologies developed at research stations in the field of crop husbandry, horticulture, animal husbandry, fisheries etc. to ensure their suitability and sustainability to the specific locations and to suggest or modify or refine the technology accordingly. This is done by testing a released technology under the real farm situations with the participation of farmers. The real problems by the farmers in the adoption of new technologies are also fed back to the research centres. KVK meets the cost of critical inputs of the programmes. The KVK Uttarkashi conducted OFT from 2005 to 2014 on various aspects of agriculture.
