Black Hawk County, IA | "Nick" is the timing of the male pollen shed to when the female is silking. If the female silks a little early it is not a major problem as the silks will keep growing waiting for pollen. However if the male pollen is throwing before the female silks then the female will not be pollinated as the pollen shed is only 7-14 days and its over. This is still one of the biggest challenges in hybrid seed corn production. J | |
