With all the bad news about the coronavirus this year, we need a miracle. It is really a miracle of nature that a puny little seedling can grow into a big, tall corn plant within a couple of months. The most crucial time in the life of a corn plant is the seedling stage. If we understand how our crops grow, we can do a better job of meeting their needs and improve the odds for getting higher yields. Let’s look at what happens as the young corn plants develop.
Stage V1 to V2 — corn seedlings need 110 to 120 growing degrees to germinate and emerge. The seedlings emerge when coleoptile, the spear-like leaf, pierces thru the ground. First and second leaves develop six to seven days after the seedlings emerge. The first roots start to supply water and nutrients to the young seedlings.… Continue readingRead More »
