Cool Season Annual Forage Mixtures Trial, Heather Darby, Sara Ziegler, Amanda Gervais, Abha Gupta, Lindsey Ruhl

Northwest Crops & Soils Program

In 2017, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of cool season annuals and mixtures of these annuals at Borderview Research Farm in Alburgh, VT. In the Northeast, cool season perennial grasses dominate the pastures and hay meadows farmers rely on throughout the season. Often times during the fall months, the perennial pasture will decline in yield and quality. Addition of cool season annual forages into the grazing system during this time may help improve the quality and quantity of forage and potentially extend the grazing season. Recently, there has been a growing …

Maximizing Forage Yields In Corn Silage Systems With Winter Grains, Heather Darby, Sara Ziegler, Abha Gupta, Lindsey Ruhl

Northwest Crops & Soils Program

Producing sufficient high quality forage on farms is becoming difficult given current economic and environmental pressures. Farmers are looking for strategies to improve yield and quality of their own forage to reduce the financial burden of purchasing feed off-farm. In addition, with increasing focus on managing farm nutrient balances for environmental reasons, farmers are also looking to decrease the importation of additional nutrients from feed onto their farms. One strategy for accomplishing this is utilizing winter grains, such as rye, wheat and triticale, as forage crops. These crops could be grazed or harvested in the fall to extend the grazing …


Forage Brassica Variety Trial, Heather Darby, Sara Ziegler, Amanda Gerrvais, Abha Gupta, Lindsey Ruhl Jan 2017

Forage Brassica Variety Trial, Heather Darby, Sara Ziegler, Amanda Gerrvais, Abha Gupta, Lindsey Ruhl

Northwest Crops & Soils Program

Forage brassicas are very cold hardy and can extend the grazing season late into the fall. They grow extremely fast and provide very nutrient dense feed at times when growth is limited for many other species. Brassicas fit well into some annual crop rotations such as small grains or summer annual forages. Adding brassicas to a grazing plan can not only extend the grazing season but can also reduce the reliance on expensive feed inputs. There are many different species of forage type brassicas on the market today including mustards, turnips, radishes, and kales. In 2017, the University of Vermont’s …

This project evaluated yield and soil health effects of five different corn …


Summer Annual Variety Trial, Heather Darby, Sara Ziegler, Erica Cummings, Abha Gupta Jan 2017

Summer Annual Variety Trial, Heather Darby, Sara Ziegler, Erica Cummings, Abha Gupta

Northwest Crops & Soils Program

Warm season grasses, such as sudangrass, and millet can provide quality forage in the hot summer months, when the cool season grasses enter dormancy and decline in productivity. The addition of summer annuals into a rotation can provide a harvest of high-quality forage for stored feed or grazing during this critical time. Generally, summer annuals germinate quickly, grow rapidly, are drought resistant, and have high productivity and flexibility in utilization. The UVM Extension Northwest Crops and Soils team conducted this variety trial to evaluate the yield and quality of warm season annual grasses.

Forage Intercropping For Resiliency Experiment, Heather Darby, Lindsey Ruhl, Amanda Gervais, Abha Gupta, Sara Ziegler

Northwest Crops & Soils Program

Producing high quality forage crops is exceedingly challenging in Vermont as climate change progresses with more precipitation, faster rates of precipitation, and higher annual temperatures (Faulkner, 2014). Knowing which cropping systems, annual or perennial, and which forage species will grow best in this challenging environment is crucial to the success of our forage-based farm operations. Increased species and variety diversity has been shown to increase resiliency or tolerance to pests and environmental stress, however it can also make it more difficult to harvest at peak quality and yield. This project evaluates the productivity of both perennial and annual forage systems …

The Efficacy Of Spraying Fungicides To Control Fusarium Head Blight Infection In Spring Malting Barley, Heather Darby, Erica Cummings

Northwest Crops & Soils Program

Public interest in sourcing local foods has extended into beverages, and the current demand for local brewing and distilling ingredients is quickly increasing. One new market that has generated interest of both farmers and end-users is malted barley. This only stands to reason since the Northeast alone is home to over 180 microbreweries and 37 craft distillers. Until recently, local malt was not readily available to brewers or distillers. However, a rapid expansion of the fledgling malting industry will hopefully give farmers new markets and end-users hope of readily available malt. To date, the operating maltsters struggle to source enough …

Hop Crowning Trial Final Report, Heather Darby, John Bruce, Abha Gupta, Freddy Morin, Scott Lewins Lewins

Northwest Crops & Soils Program

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 either before or at the time that new growth has just emerged from the soil.

Hop Germplasm Study, Heather Darby, John Bruce, Abha Gupta, Scott Lewins, Freddy Morin

Northwest Crops & Soils Program

Until now, commercial hop (Humulus lupulus L.) production has not occurred in the northeast (NE) region of the United States for 150 years. Vermont production peaked in 1860 when the state produced 289,690 kg of dried hops (Kennedy 1860). A combination of the spread of hop downy mildew, the expansion of production in western states, and prohibition laws from the 1920’s contributed to the decline of the 19th century NE hop industry. Today, the Pacific Northwest states of Washington, Oregon, and Idaho remain the dominant hop production sites of the U.S. However, hop production in non-traditional regions is growing and …


Hop Harvest Timing, Heather Darby, John Bruce, Scott Lewins Jan 2017

Hop Harvest Timing, Heather Darby, John Bruce, Scott Lewins

Northwest Crops & Soils Program

In the Northeast, hop harvest generally begins in mid-August and continues through mid-September. Harvest date is primarily dependent on the hop variety but weather can delay or hasten maturation and impact when harvest will occur. In addition to weather, various pests, such as spider mites and downy mildew, can similarly impact harvest timing. The time at which you harvest hops can affect the various qualities of your finished product. Alpha and beta acid content peaks before many essential oils have fully developed. Delaying harvest can provide time for these oils to develop but increases the amount of time the hops …
