On Farm Testing is to test and evaluate the research findings of Research Stations at the farmer's field and to refine and modify the technologies, if required for better adoption by farmers. It is confirmation of already proven research results under real farming situation. Based on the background information that the farmers do not adopt about 70% of the available technologies and hence it becomes necessary to take up farmer participatory testing of research findings in their own farms. Apart from convincing them it is also given an opportunity to refine or modify the recommendations to suite the requirements of the farmers in a given farming situation. Economically viable, operationally feasible technologies matching with farmers needs are identified to solve the problem faced by them.

The procedure of On-farm research has five steps viz.,

  • Diagnosis
  • Planning
  • Experimentation
  • Assessment / Evaluation of results
  • Recommendation and diffusion

There is, however, a considerable overlap and feedback among these five steps.

Diagnosis: The diagnostic stage involves collecting and analyzing information in order to design On-farm experiments. In this steps, an understanding of farmers’ circumstances and practices are made in order to; i) understand the farming system, and system interaction; ii) identify possible productivity problems; and iii) begin to develop hypotheses on possible solutions.

Planning: The planning on On-farm research is used to identify experimental factors to be included in on-farm experiments, as well as to suggest other research activities. There are six practical steps for research planning.

  • Listing problems
  • Ranking problems
  • Identifying causes of problems
  • Diagram problems and causes
  • Listing possible solutions
  • Screening possible solutions for feasibility

Experimentation: On-farm experiments are conducted in the fields of representative farmers and to examine a small number of experimental variables. Those experiments may be described and classified in a number of ways, but regardless of classification most of them progress from exploring production problems, to testing possible solutions, and then to verifying recommendations and demonstrating them with farmers.

Assessment: The results of the on-farm experiments should be analyzed carefully. The analysis requires an assessment of farmers’ reactions and opinions. A thorough agronomic interpretation, and careful statistical and economic analysis will be helpful to this stage. The results of the assessment are then used to plan future research and to make recommendations for farmers.

Recommendation and Diffusion: When researchers are confident that they have enough information, they can formulate recommendations and non-recommendations can be released for demonstration on a larger area in the farmers’ fields.

KVK submits the Action Plan for technical intervention to ICAR – ATARI. Based on the approval KVK conducts On Farm Testing in Field Crops, Horticulture Crops, Farm Implements, Enterprises and Livestock in the district.
