There’s all the time loads of consideration paid to getting grain corn off to a great start, and the identical ideas apply when it comes to the finer factors of planting corn for silage.
With seed deliveries underway and planting season across the nook, Alana Serhan, market growth agronomist for Delight Seeds in Western Canada, takes us by the very best administration practices for planting silage corn on this new Corn College episode.
To start, she recommends that a farm develop a number of hybrids: “Having two or even three silage hybrids on farm helps spread out risk, and helps with maturity, making sure whole plant moisture is ideal as we go through the silage chopping season.”
The following crucial resolution is when to start planting. Corn received’t germinate till soil temperatures are round 10 levels Celsius, she explains, noting temperatures close to the floor can change relying on daylight and time of day.
“That first drink of water that corn seedling takes in needs to be warm,” stresses Serhan. “If it’s going to imbibe that cold drink of water, we see things like cork-screwing, root development but no coleoptile, no emergence happening, and that often leads to a replant scenario.”
One space the place the strategy to silage corn can differ from grain corn is with seedbed and residue administration, as silage producers have a tendency to have extra corn-on-corn acres.
Trash-whippers or row-cleaners are your good friend, says Serhan, however ensure they’re set correctly.
“We don’t want to create a trench where cold moisture, potentially snow can sit. We only want them tickling the surface moving debris when needed,” she explains.
Lastly, most silage producers have entry to manure, nevertheless it’s simply as necessary to listen to nutrient wants of corn being grown for silage as it’s for grain. As a common rule, Serhan says for each tonne of silage, you want about 4 to six kilos of nitrogen on a per-acre foundation. And you probably have any skill to put down starter fertilizer, do it, particularly in Western Canada in soils that aren’t all the time best, she says.
