To calculate the number of seeds to be distributed, it is necessary to know the germination power of the seed lot. This information is provided by the company where the seeds were purchased, but this value (% germination) may be higher than the emergence value of the seeds in the field. Therefore, it is recommended that an emergence test be carried out in the field. To do this, from a representative sample, four sub-samples of 100 seeds each are separated. These should be sown at a depth of 3 to 5 cm in prepared soil, in four rows of 4 m each. Soil moisture should be maintained at an adequate level for emergence during the evaluation. A count is made in each of the four rows when the plants have their first pair of leaves fully open (approximately 10 days after sowing), considering only vigorous plants. The percentage of emergence in the field will be the arithmetic mean of the number of emerged plants per meter of row.

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