2. SEED SAMPLING - SeedNet

~--~
kind of container or from streams of seed entering containers the following shall
be regarded as the minimum requirement.
Lot Size Number of primary samples to be taken
Up to 500 kg At least five primary samples.
501-3,000 kg One primary sample for each 300 kg, but not
less than five primary samples.
3,001-20,000 kg One primary sample for each 500 kg. but not
less than 10 primary samples.
20,001 and above One primary sample for each 700 kg, but not
less than 40 primary samples.
8. Care must be exercised in reducing composite samples. Careless splitting
of the sample cannot be expected to produce two similar portions.
9. Any seed known to have been treated with a poisonous fungicide should be
identified so that the person who subsequently may handle the sample will be
infonned of the potential hazard.
10. While taking samples from machine sewed cotton bags, a few stitches at
,oneof the top comers can be loosenlbroken and then this break can pe closed with
hand stapling device after the contents of the bag have been sampled or a self
adhesive label shall be affixed to ensure proper sealing and to avoid a tampering.
11. The weight of the sample drawn should not be less than the weight of the
submitted sample prescribed in the Table 2.1.
MEmOD OF OBTAINING PRIMARY SAMPLES
The primary samples are drawn with the aid of suitable seed triers/or by hand
in case of chaffy/non free-flowing seeds.
When the lot is in bags, the bags to be sampled should be selected at random
throughout the lot and primary samples drawn by inserting the trier gently into the
bags, pointing upwards at an angle of about 30 to the horizontal, with the hole
facing downward until it reaches the centre of the bag. The trier is then revolved
