I. Application and Amplification of General Seed Certification Standards

The General Seed Certification Standards are basic and together with the following specific standards

constitute the standards for certification of jute seed.

 

II. Land requirements

Land to be used for seed production of jute shall be free from volunteer plants.

 

III. Field Inspection

A minimum of three inspections shall be made in such a way that the first inspection is done prior to flowering,

the second from bud stage to peak flowering, and third prior to harvesting. 

 

IV. Field Standards

A. General requirements

 

1. Isolation

    Jute seed fields shall be isolated from the contaminants shown in the column 1 of the Table below by the 

distances specified in columns 2 and 3 of the said Table:


        Contaminants                                                                                   Minimum distance (meters)

            1                                                                                                         2                     3


Fields of other varieties                                                                                   50                   30

Fields of the same variety not conforming to the

varietal purity requirements for certification                                                      50                   30
