FACTORS AFFECTING THE GERMINATION AND ESTABLISHMENT OF MONOGERM SUGAR BEET
2.2.6 Post harvest treatments
The standard post harvest treatment to raw seed is a complicated and exacting operation but in outline the following is carried out: -
1) Pre-cleaned (to remove stick & leaf) and dried to below 15% moisture at a temperature not greater than 120°F (49°C).
2) Cleaned with aspiration using round hole screens to remove small and dead seeds.
3) Monogerm seed is separated from multigerm seed using a combination of round hole and slotted screens.
4) The monogerm seed extracted is graded to size specifications - usually 2.75 - 4.00 mm.
5) The graded monogerm seed is gravity separated to extract light "weak" seeds to improve germination.
6) The product is soaked in a fungicide solution of organic Ethyl Mercury Phosphate (E.M.P.) for twenty minutes - by using a concentration of 40 ppm. E.M.P. and a ratio weight of three parts water to one part seed.
7) The final seed product is then regraded to size specifications (Lindsay 1980, personal communication).
8) Pelleted.
