Description
This unit of competency describes the skills and knowledge required to determine the weight per 1000 pure seeds from a submitted sample.It applies to senior seed analysts who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare a working sample
  • 1.1 Obtain pure seed following a purity analysis or as a representative fraction of a submitted sample
  • 1.2 Use mechanical dividers where appropriate
  • 1.3 Maintain moisture content of working sample before counting through storing it in moisture-proof containers
  • 1.4 Complete labelling and records
2. Count and weigh seed by machine
  • 2.1 Put the entire working sample through a counting machine and record the total number of seeds indicated
  • 2.2 Weigh working sample to the required number of decimal places
3. Count and weigh replicates by hand
  • 3.1 Count out eight replicates of 100 seeds randomly from the working sample
  • 3.2 Weigh each replicate to the required number of decimal places
  • 3.3 Record weights of each replicate
  • 3.4 Calculate variance, standard deviation and coefficient of variance
  • 3.5 Test a new set of replicates where the coefficient of variance exceeds the prescribed value
  • 3.6 Determine the average weight of 1000 seeds where the coefficient of variance does not exceed the prescribed value
4. Report results
  • 4.1 Report results of weight determination under "other determinations" to the prescribed number of decimal places
  • 4.2 Report the method used and the results calculated
