Sowing Suitability of Seeds

the percentage of seeds in a given batch that are suitable for sowing. This figure, based on indexes of cleanliness and germination, is established by multiplying these indexes and dividing by 100. The result is rounded to a whole number. The percentage arrived at is used to determine exact seeding rates, which are adopted for different crops and are based on a maximum possible rate of 100 percent sowing suitability. Since seeds in a given batch rarely meet this standard, the seeding rate is increased by introducing an adjustment for sowing suitability.
