Recent research shows that under good conditions, daily yield losses for soybeans are 0.3, 0.4, and 0.5 percent per day of planting delay for the first, second and third 10-day periods in May. Total yield loss potential mounts to roughly 15 percent by the end of the month.
Uneven emergence, skips, doubles, and uneven spacing all reduce corn yield potential. The later a plant emerges relative to the plants next to it, the less that plant will contribute to overall yield. Those plants tend to stay behind throughout the season.
Soybean stand establishment can sometimes be an easy thing, and yet there are always instances where it may take a heroic effort. Spring of 2019 could be looking for some heroes.
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.
