    Seed testing

    Seed testing is the science of evaluating the planting value of the seeds. The primary aim of the seed testing is to obtain accruable and reproducible results regarding the quality status of the seed samples submitted to the Seed Testing Laboratories.

    mal


    1. Service samples for the farmers, producers and sellers on payment of cost @ Rs. 30/- per sample to know the seed standard of their seeds. This type of samples is drawn and send to the seed testing lab by the Farmers, Producers and the sellers to know their seed standards.

    b

     

    The samples received from the three categories are analysed and results are communicated to the concerned within 30 days from the date of receipt of the samples.

    Anybody including farmers can test their samples for it standard before the seeds are being certified, sold or sown.

    2. Certified samples for certification purposes on payment of Rs. 20/- per sample by the producers as testing charges collected at the time of registration.

    This type of samples is drawn by the certification officers and send them to the seed testing lab through the Assistant Director of Seed Certification with a secret code No. On receipt of the results the code will be decoded by the ADSC and then the results are sent to the producer for further certification procedure to be completed.

    2. Official samples for the quality control purpose at government cost. This type of samples are drawn by the seed inspectors for the quality control as per the seed control order and Seed act to assure the availability of quality seeds to the farming community.

    The following tests are conducted

    • Germination
    • Physical purity
    • O.D.V.( Other Distinguishable Variety)
    • Moisture

    The Seed Testing Laboratory is the hub of seed quality control. Seed testing services are required from time to time to gain information regarding planting value of seed lots. Seed testing is possible for all those who produce, sell and use seeds.
