This is considered as an additional inspection for cotton seed farms and should be reported in inspection report form. During inspection, the SCO has to ascertain whether the kapas harvested from the seed farm is available or not.

Ginning of cotton kapas 

 

The cotton kapas collected from passed seed farm, have to be ginned at the approved ginning unit.

 

The seed kapas stored at growers premises should be moved to the Ginning unit after sealing along with the processing report within THREE months from the date of final inspection. The Sealing intimation procedures as already said need to be followed.

 

Before commencing ginning of kapas, the gins have to be dismantled and thoroughly cleaned to avoid admixture of seeds.

 

The seed certification officer in the ginning unit should verify the stock and make necessary entries and permit for ginning. The ginning operation shall be carried with the knowledge / care of the concerned unit Seed Certification Officer.
