To calculate the number of seeds to be distributed, it is necessary to know the germination of the seed lot. This information is provided by the company where the seeds were purchased, but this value (% germination) may be greater than the value of emergency seeds in the field. Therefore it is recommended to make an emergency field testing. Therefore, from the representative sample, four separate sub-samples each of 100 seeds. These should be sown to a depth of 3 to 5 cm in soil prepared in four rows of each 4 m. Soil moisture should be maintained at an adequate level for emergency during the evaluation of the implementation. It counts up at each of four lines, where plants are the first pair of leaves completely open (approximately 10 days after seeding), considering only the vigorous. The percentage of emergence in the field will be the average of the number of emerged plants per row meter.

The number of plants / linear meter to be achieved in agriculture is estimated taking into account the desired plant population / ha and the adopted spacing.
