Fertility Components Critical For High Yield Corn

Nitrogen. Multiple applications of N are more efficient and result in higher yields (preplant, starter, pre-tassel applications through pivot or sidedress, and post-tassel applications). Additionally, multiple applications improved N use efficiency and reduce potential for stalk rot organisms to infect corn stalks. Post Tassel N Applications. Post-tassel (post-flowering) applications of N can increase yields by …
