Recently, there has been an increased interest in improving sowing technologies and practices, as sowing is one of the most important, if not the most critical, operations that a farmer carries out during the growing season. The emergence dynamics of sown seed have been suggested by several authors to have an impact on yield potential. This condition was studied in two crop years that differed in environmental conditions. Under these effects, individual yields of the earliest- and later-emerged plants were examined. Various physical parameters were measured, such as ear weight, ear length, ear diameter, as well as individual grain weight, thousand grain weight and number of grains. Correlation was found between these yield parameters and the ripening time. Our results confirmed that there is an influence of the emergence dynamics on the yield potential, as the earliest-emerging plants yield the highest yield. Therefore, our breeding technology should also meet the goal of getting as many plants to germinate in the first emergence period.
