    Technology Assessment and Refinement (TAR)

    1. Meaning
    • TAR is a systematic process to test, evaluate, refine, and adapt agricultural technologies under real farming conditions before large-scale dissemination.
    • It ensures that technologies developed at research stations are feasible, acceptable, and sustainable in farmers’ fields.

     

    1. Why TAR is Needed?
    • Many technologies fail when transferred directly from research stations → farmers’ fields.
    • Differences in soil, climate, resources, socio-economic conditions affect adoption.
    • Hence, technologies must be assessed and refined with farmers’ participation.

     

    1. Steps in Technology Assessment and Refinement
    1. Technology Assessment
      • Test a technology in real farm situations.
      • Check for technical feasibility, economic viability, social acceptability, and environmental sustainability.
      • Examples: Testing a new crop variety, fertilizer dose, irrigation method.
    2. Technology Refinement
      • Based on farmer feedback and field results, modify or fine-tune the technology.
      • Example: A new paddy variety matures late → scientists may refine it with farmer input (selecting early maturing alternatives).
    3. Validation
      • Re-test the refined technology in multiple farm locations.
      • Ensure consistency of results.
    4. Dissemination
      • Once proven suitable, spread through extension systems, FPOs, KVKs, FFS, etc.

     

    1. Types of TAR Activities
    • On-Farm Trials (OFTs): Conducted in farmers’ fields to test new technologies.
    • Front Line Demonstrations (FLDs): Large-scale demonstrations on farmers’ fields under ICAR/DAE schemes.
    • Adaptive Research Trials (ARTs): Trials adapted to local conditions before large-scale promotion.

     

    1. Institutions Involved in India
    • Krishi Vigyan Kendras (KVKs): Major role in OFTs & FLDs.
    • ICAR Research Institutes & SAUs: Develop and refine technologies.
    • ATMA & Extension Departments: Help in dissemination.

     

    1. Examples
    • A new wheat variety developed by ICAR tested in farmers’ fields in Uttar Pradesh → found to be prone to lodging → refined by recommending lower nitrogen dose.
    • IPM modules tested in cotton fields with farmer participation → refined by adding neem-based biopesticides.
