Last fall’s wet harvest conditions exposed the soybean seed crop to two key diseases. Phomopsis seed decay (diaporthe longicolla) attacks soybean seeds that are shriveled or have a cracked seed coat, often appearing as a chalky white covering on the seed.
Early weed competition in soybeans can reduce yields where glyphosate is not applied early.
That’s the answer to how long it takes for corn to emerge; in other words, it depends.
When weather conditions turn cold and wet, young corn plants can become stressed. That impacts their ability to take up nutrients.
Here is an easy test to help determine if soil is ready for planting.
Slow down and take the time to make sure things are right, with you, with the seedbed, with the planter.
Especially when the forecast turns cold and wet, a starter fertilizer may help get the seedlings off to a good start.
Recent rains have challenged southern growers planting plans. AgVenture reminds growers to be steadfast and wait for ideal planting conditions.
Picket fence corn stands – those that are exactingly uniform, have the most potential to produce maximum yields. Even spacing and emergence are of critical importance to maximizing yields.
While residue prevents erosion and provides organic matter, it also holds moisture and prevents optimal drying and warming of the seedbed.
In this issue of Product / Technology Update, we look at the science behind some of the key factors corn seedlings face at emergence.
Planting before a cold period with rain and/or snow can greatly impede stand establishment and resulting yield potential. Corn seed once in the ground wants to germinate.
Ideal temperature for planting occurs when soil temperatures are above 50℉ and temperatures are on a rising trajectory. At this temperature, seed will imbibe roughly 30 percent of its weight in water.
Factors that inhibit ideal emergence and promote seedling disease include extended cool and wet conditions or exceptionally dry or crusted seedbeds following planting.
When you look down the uniform, picket-fence rows of your newly emerged crop, you know without a doubt that you made the right seed choice, your planter was perfectly calibrated and Mother Nature
