Winter Crops and Sunflowers

Winter Crops and Sunflowers

By Tina Saravia

When I started planting my winter vegetables this fall, I was looking forward to some radishes carrots, snow peas, spinach - the cool weather vegetables.

As the seeds started sprouting and slowly growing through the cooler weather and shorter days, I started noticing an unexpected crop.

I had previously planted some black oil seed sunflower (Helianthus annulus) in the same bed. Apparently, I missed some seeds when I harvested the sunflowers. So, alongside my vegetable crop, these sunflowers started growing. One of them has even bloomed. I was not aware that they grow this late in the year, much less bloom in late fall amidst the frosty weather and all the rains.

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
