The main objective of seed sampling is to obtain a representative sample of each lot of seed under certification.
The term seed lot is used to represent a fixed quantity of agricultural seeds i.e.
When a seed lot is sampled either from containers or in bulk several individuals samples are drawn from different containers, each such sample is called a primary sample.
All the primary samples drawn from one lot are combined to form a bulk and is called composite sample which is generally much larger than required for analysis.
A portion of seed derived from the composite sample to be submitted for analysis to Seed Testing Laboratory is called submitted sample.
The sample derived in the Laboratory from the submitted sample and is used for analysis is called as working sample.
|A. FOR PACKED SEED|
|1||Upto 5 containers||Sample from each container at least 5 primary samples|
|2||6 to 30 containers||Sample is drawn from 5 containersor at least one in every 3 containers whichever is greater|
|3||More than 30 containers||Sample from at least in every 5 containers or at least from 10 containers which ever is greater.|
|B. FOR BULK SEED|
|1||Less than 50 kg||At lest 3 primary samples|
|2||50 to 500 kg||At least 5 primary samples|
|3||Above 500 kg upto 3000 kg||One primary sample for each 300 kg but the number should not be less than 5|
|4||Above 3000 kg||One primary seed sample for each 500 kg but the number of primary seed samples should not be less than 10|
|Crop||Minimum lot size (q.)||Minimum Submitted Sample||Sample Size (gms.) Working Sample For|
