Sunflower Reduced Tillage Trial, Heather Darby, Hannah Harwood, Erica Cummings, Susan Monahan
Northwest Crops & Soils Program
Sunflowers are being grown in the Northeast for their potential to add value to a diversified operation as fuel, feed, fertilizer, and an important rotational crop. However, early season weed competition can limit the yields of sunflower crops, especially when wet or adverse soil conditions do not allow for mechanical cultivation in early summer. Planting sunflower into a freshly-terminated cover crop of winter rye could help reduce weed pressures. Winter rye would suppress weed germination by covering the ground early in the season, and also through the allelopathic compounds produced in the plants’ roots, which inhibit germination of small-seeded plants. …

Sunflower Variety Trial, Heather Darby, Hannah Harwood, Conner Burke, Erica Cummings, Susan Monahan
Northwest Crops & Soils Program
Sunflowers are being grown in the Northeast for their potential to add value to a diversified operation as fuel, feed, fertilizer, and an important rotational crop. The major sunflower production areas are in the northern Great Plains, so seed production and agronomic management guidelines generally come from this region. Identifying varieties of sunflower that will perform well in Vermont’s particular climate is essential to viable crop production. With this in mind, UVM Extension’s Northwest Crops and Soils Program have been evaluating sunflower varieties for their performance in our microclimate.

Winter Canola Survival, Heather Darby, Hannah Harwood, Erica Cummings, Susan Monahan
Northwest Crops & Soils Program
Winter canola (Brassica napus) is a relatively new crop in Vermont. This crop has the potential to be added into a rotation to both promote soil health and yield a crop for oil production. Generally planted in late August or early September, winter canola should produce ample vegetation and root growth prior to plant dormancy (Figure 1). Growers can often fit a canola crop in after harvesting winter grains or other early crops. Regrowth in the spring depends on the harshness of winter conditions, but generally the plants are “greening up” in April, and will enter the rosette stage and …
Cover Crop Planting Date X Seeding Rate Trial, Heather Darby, Conner Burke, Erica Cummings, Hannah Harwood, Susan Monahan
Cover Crop Planting Date X Seeding Rate Trial, Heather Darby, Conner Burke, Erica Cummings, Hannah Harwood, Susan Monahan
Northwest Crops & Soils Program
When corn silage is harvested in the fall, the entire plant is removed, leaving the soil exposed through the winter. Many farmers have started to plant cover crops following corn harvest because of the multitude of benefits cover cropping brings to soil health and fertility. The cover crop protects the soil from erosion, adds organic matter, and also scavenges excess soil nitrogen (N), releasing it again after cover crops are terminated in the spring. This keeps the nitrogen from potentially being lost through leaching, which, in addition to the soil benefits, provides a financial benefit to farmers – less nitrogen …

Enhancing Forages With Nutrient Dense Sprays 2013 Trials, Heather Darby, Susan Monahan, Conner Burke, Erica Cummings, Hannah Harwood
Northwest Crops & Soils Program
The nutrient dense study was continued at two locations in Vermont during the 2013 growing season to evaluate the efficacy of amending forages with foliar sprays. The nutrient spray program was developed by Advancing Eco-Agriculture and consisted of five foliar sprays for the farms in this study. The recommended spray program included applications of Rejuvenate in the early spring and late fall, and a combination of PhotoMag, Phosphorus, Potassium and MicroPak applied in the spring and after each cut of hay or graze (Table 1). This study was conducted based on farmer interest in enhancing nutrient density of forages through …
