Field emergence

As germination or emergence is known in agriculture, the ratio of young crops , the at some point topsoil , have pierced the total number of sown seeds . The prospective field emergence can be predicted by laboratory determination of the germination capacity and driving force. The methods used for this are defined by the International Seed Testing Association (ISTA) and are valid worldwide.

In the case of broad and drill sowing , the amount of seed required is increased in relation to the desired plant population, whereas in the case of single-grain sowing , 100% field emergence is aimed for, as this is the only way to achieve the optimal plant spacing. There is a risk of stock shortages due to emergence diseases and pests , especially rooks . In order to achieve optimal crops , the sowing and seedbed preparation requires special care, which is given by the germination requirements of the respective plant species ( dark germinator or light germinator ).
