No farmer will begin to sow without knowing the germination of seeds. This is understandable. Without knowledge of germination, it is impossible to install a seeder for seeding at a given rate. We will have to sow "by eye," and this will certainly lead to a shortage of crops. It is necessary to know the seeding rate in research work, even when conducting not very complex experiments that we offer you in this brochure.
