EVALUATING THE EFFECT OF BSN ON SEED GERMINATION AND VIGOUR

TB161 recommends the appropriate testing procedures for both laboratory testing and field testing when evaluating the effect of BSN on seeds.

Dr Hooshang Nassery, RLF’s Head of Technical carefully charts the parameters that are considered the best indicators of the beneficial effects of BSN on seed.

BSN is RLF’s world-leading Seed Priming product, now being used by more than three million farmers across many cropping environments and world markets.

TB161 places emphasis on comparison between the control (untreated) and treated seeds for both laboratory and field usingsoil that closely characterises the targeted farm soil. A preview of the document shows that some of the measuring parameters that are good indicators of the beneficial effects of BSN are described as follows :

  • percentage of germination
  • percentage of abnormal seedlings (seedling that fail to establish)
  • number of days from the start until completion of germination
  • uniformity of germination
  • seedling establishment and vigour
  • humus formation in the rhizosphere
  • earliness of tillering in cereals

Photographic record is strongly suggested for keeping a record of the comparative and quantitative measurements. RLF’s Protocol Document, with easy to read instructions and guidance titled ‘How to Apply BSN to Seed‘, is recommended reading particularly as it relates to the recommended range of product and water.
