Flax Planting Date Trial, Heather Darby, Abha Gupta, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
Early seeding of flax generally produces the best yields and quality. Moderate temperatures and sufficient soil moisture during flowering and seed development are important for high yield and quality, and these conditions are more likely to occur with early seeding. There is little risk of frost damage with flax. Newly emerged flax can withstand temperatures down to 27O F, while plants past the two leaf stage can withstand temperatures as low as 18O F. Flax has small leaves and is relatively short, which naturally makes it less competitive against weeds. Early planted flax will establish before the majority of summer …

Dry Bean Seeding Rate Trial, Heather Darby, Erica Cummings, Lily Calderwood, Abha Gupta, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
Dry beans (Phaseolus vulgaris), a high-protein pulse crop, have been grown in the Northeast since the 1800’s. As the local food movement expands, consumers have requested stores stock more and more locally-produced foods and heirloom dry beans are no exception. Currently, the demand for heirloom dry beans has exceeded the supply. Little agronomic information exists for production of dry beans in New England. In 2015, as part of a USDA NE-SARE Partnership Grant (PG15-045) the UVM Extension Northwest Crops and Soils Program established a dry bean seeding rate trial to determine the optimal seeding rates for three types of dry …
Oilseed Meal As A Fertility Amendment In Sweet Corn, Heather Darby, Abha Gupta, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Oilseed Meal As A Fertility Amendment In Sweet Corn, Heather Darby, Abha Gupta, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
Many Northeast growers are integrating oilseed crops such as canola, soybeans, and sunflower into their operation, in hopes of on-farm fuel production, value-added products, and/or livestock feed. Many producers are using small-scale presses to mechanically separate oil from the seed. Oilseed meal, the highprotein byproduct left after the extrusion of oil, can be milled and used as a soil amendment to increase fertility and organic matter. This material has the potential to replace high-cost imported fertilizers, especially for organic growers.
Tillage Radish Planting Date X Seeding Rate Trial, Heather Darby, Hillary Emick, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Tillage Radish Planting Date X Seeding Rate Trial, Heather Darby, Hillary Emick, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
Farmers are interested in growing tillage radishes as they may potentially offer many environmental and economic benefits. Tillage radishes are quick at scavenging excess nitrogen, provide good ground cover, and break down very quickly in the spring to make way for spring planting. The plants winter kill, but the dead frozen plant material can still supress the earliest spring weeds from establishing. The roots themselves are known to drill through compacted soil layers as they grow, and the holes left by decomposed roots the next spring may also allow more water to infiltrate into the soil. Growing tillage radish as …
Pasture Productivity Trial, Heather Darby, Abha Gupta, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Pasture Productivity Trial, Heather Darby, Abha Gupta, Lily Calderwood, Erica Cummings, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
Pasture is an essential component of feed for dairy cattle on organic farms. Productivity of pastures is essential to ensure the cattle have a plentiful source of high quality feed during the entire grazing season. Optimal management of pastures should include animal, plant, and soil factors. This project aims to identify weak links in the pasture system and evaluate the impact of adopting new strategies to overcome barriers to productivity. In this case, soil fertility and species diversity were identified as the weak links to productivity.

Hop Compost Tea Trial, Heather Darby, Julija Cubins, Lily Calderwood, Erica Cummings, Abha Gupta, Julian Post, Sara Ziegler
Northwest Crops & Soils Program
As the acreage of hops continues to rapidly expand in the northeast, there is a great need for production knowledge specific to our region. Downy mildew has been identified as the primary pathogen plaguing our hop yards. This disease causes reduced yield, poor hop quality, and in extreme cases, plant death. Control measures are desperately needed that can effectively reduce disease incidence and have a minimal impact on the environment. Farmers have increasing interest in the potential impact of bio-based foliar products on yield, quality, and disease incidence of hops. Compost teas have been used to control disease and provide …
Enhancing Forages With Nutrient Dense Sprays Final Report, Heather Darby, Susan Monahan
Enhancing Forages With Nutrient Dense Sprays Final Report, Heather Darby, Susan Monahan
Northwest Crops & Soils Program
The purpose of the Nutrient Dense Spray (NDS) trial was to evaluate the impact of nutrient dense foliar sprays on perennial forage yield, quality, and fatty acid concentrations. The nutrient spray program was developed by Advancing Eco-Agriculture (Middlefield, OH) and consisted of five foliar sprays specifically recommended for the farms participating in this study. The recommended foliar applications were evaluated over 3 growing seasons. In the third year of the study, a sixth foliar spray, ‘Sea Shield’ was added to the treatments. The recommended spray program included applications of Rejuvenate in the early spring and late fall, and a combination …

Hop Pest Scouting Report, Heather Darby, Lily Calderwood
Northwest Crops & Soils Program
During the 2015 growing season, the major pest challenges we encountered at the hopyard at the Borderview Research Farm in Alburgh, Vermont were potato leafhopper (Empoasca fabae), and hop downy mildew (Pseudoperonospora humuli), as well as a few secondary plant diseases.

As the acreage of hops continues to grow in the northeast, there is increasing need for regionally specific agronomic information. The majority of hop production and research is conducted in the Pacific Northwest, a region that has a much drier climate than our own. The University of Vermont (UVM) has carried out a number of trials to build relevant experience on small scale hop production in our wet and cool climate. The results and observations from our hops research can be found on the UVM Extension Northwest Crops and Soils website: www.uvm.edu/extension/cropsoil/hops. As for any perennial crop, managing weeds can …

Downy mildew has been identified as the primary pathogen plaguing our northeastern hop yards. This disease causes reduced yield, poor hop quality, and can cause the plant to die in severe cases. Control measures that reduce disease infection and spread while minimizing the impact on the environment are desperately needed for the region. Mechanical control is one means to reduce downy mildew pressure in hop yards. Scratching, pruning, or crowning is a practice initiated in the early spring when new growth has just emerged from the soil.
