On Farm Testing is aimed at testing the proven technologies evolved at Research Stations on farmers’ field with their farming system perspective in view under their management and their active participation so as to convince them the relevance and viability of the new technology.
During this year 2009, the following 12 OFT Programmes viz., White fly Management in Cotton, Mealy bug Management in Cotton, Management of Downy mildew in Grapes, Management of Sigatoka leaf spot in Banana, Management of Tea mosquito bug in Cashew, Management of Phytopthora wilt in Betel vine, Management of Fruit fly in Annual Moringa, Management of Pseudostem weevil in banana, Assessment of suitable method of planting in banana for higher profitability, Approaches for drudgery reduction and quality improvement of banana fibre, Assessment of suitable goat Breed for higher productivity, Effect of EM in uptake efficiency, cost reduction, quality and milk production were implemented.
The needed critical inputs for trial were given to the farmers and study was carried out to know the viability of the technologies tested. The field testing was carried out involving 88 farmers in an area of 42.6 ha.
