Soybean Cover Cropping Trial

In 2016, the University of Vermont Extension Northwest Crops and Soils Team interseeded cover crops into soybean varieties to evaluate cover crop establishment and effect on soybean yield at Borderview Research Farm in Alburgh, VT. Growing conditions in Alburgh are conducive to grow soybeans from maturity group 1.8 and under. Due to the later harvest date of soybeans in Vermont, little research has been done of cover crop establishment. Cover crops, particularly legumes, have difficultly establishing after the late soybean harvest and are not able to develop enough biomass to protect the otherwise bare soil during the winter. In an effort to support and expand the local soybean market throughout the northeast and increase soil health in fields rotated with soybeans, the University of Vermont Extension Northwest Crop and Soils (NWCS) Program, as part of a grant from the Eastern Soybean Board, established a trial in 2016 to evaluate cover crop seeding methods and establishment in soybeans

Organic Soybean Variety Trial

In 2016, the University of Vermont Extension Northwest Crops and Soils Team evaluated yield and quality of organic soybean varieties at Borderview Research Farm in Alburgh, VT. Growing conditions in Alburgh are conducive to grow soybeans from maturity group 1.8 and under. Due to the short growing season in Vermont, little research has been conducted on soybeans and the insects and diseases that can affect their harvest yield and quality. Soybeans are grown for human consumption, animal feed, and biodiesel. In an effort to support and expand the local soybean market throughout the northeast, the University of Vermont Extension Northwest Crop and Soils (NWCS) Program, as part of a grant from the Eastern Soybean Board, established trials in 2016 to evaluate soybean varieties under conventional management to evaluate which ones thrive in our northern climate

Oat Variety Trial

Oats (Avena sativa L.) have a long history of production in the Northeast. Although most oats are planted for a cover crop or forage, grain oats are a potential revenue source for farmers. According to the 2007 census, about 200 acres of land in Vermont is cultivated for oat grain production, with an average yield of 1747 lbs per acre. With the exception of hull-less varieties, oats need to be de-hulled before being used for human consumption and further processing is required to make oatmeal, steel cut oats, or oat flour. Since 2009, the University of Vermont Extension Program has conducted oat variety trials to provide yield comparisons in Vermont’s climate. Varietal selection is one of the most important aspects of crop production and significantly influences yield potential. It is important to remember, however, that the data presented are from replicated research trials from only one location in Vermont and represent only one season. The goal of this project was to evaluate yields and protein of eleven oat varieties

Summer Annual Forage Mixtures Trial

In 2016, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of six summer annual forage species and five mixtures at Borderview Research Farm in Alburgh, VT. In the Northeast, cool season grasses dominate the pastures and hay meadows farmers rely on throughout the season. With the onset of hot summer weather, these grasses enter dormancy and slow in production leading to what is generally referred to as the “summer slump”. In addition to this loss in production, organic producers must provide animals with 30% of their dry matter intake (DMI) from pasture over at least 120 days of the year. These constraints, in combination with variable weather, can make it very difficult to produce adequate forage from these cool season perennial grasses alone to meet the farmer’s needs. Summer annual species thrive in hot weather and can be grazed to help reach the pasture requirement or can be used as stored feed to supplement other sources. Recently, there has been a growing interest in utilizing multiple species to maximize forage yield and quality. In 2015, we trialed three- and five-way mixtures of various summer annual grass, legume, and forb species. We found it very difficult to establish a well-balanced mixture as the grasses tended to outcompete the other species. In 2016, we simplified the project to examine seeding rates of summer annual legumes and grasses to better understand how to establish mixtures of these species and be able to benefit from both species. While the information presented can begin to describe the yield and quality performance of these forage mixtures in this region, it is important to note that the data represent results from only one season and one location

Soybean Variety Trial

In 2016, the University of Vermont Extension Northwest Crops and Soils Team evaluated yield and quality of short season soybean varieties at Borderview Research Farm in Alburgh, VT. Due to the short growing season in Vermont, little research has been conducted on soybeans and the insects and diseases that can affect their harvest yield and quality. Soybeans are grown for human consumption, animal feed, and biodiesel. In an effort to support and expand the local soybean market throughout the northeast, the University of Vermont Extension Northwest Crop and Soils (NWCS) Program, as part of a grant from the Eastern Soybean Board, established a trial in 2016 to evaluate soybean varieties under conventional management to see which varieties and characteristics thrive in our northern climate

Hop Crowning Trial

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

Hop Biofungicide Trial

Downy mildew has been identified as the primary pathogen plaguing northeastern hop yards. This disease causes reduced yield, poor hop quality, and, in severe cases, plant death. Control measures that reduce disease incidence and have a low environmental impact are desperately needed for the region. Regular application of protectant fungicide sprays is an effective method for managing downy mildew pressure in hop yards. However, regular chemical applications can lead to residual toxicity in the soil and have a negative effect on beneficial organisms. Extended use of protectant and curative fungicides can also lead to pathogen resistance. The goal of this project was to evaluate the efficacy of organic approved biofungicides with a variety of active ingredients for control of downy mildew in hops

Hop Optimal Irrigation Trial

Hops reportedly use about 610 to 715 mm (24 to 28 inches) of water per year (Evans 2003). Rainfall can contribute to this total, however, due to climatic variability, it is important that hops are irrigated regularly to combat moisture stress. Moisture deficit during the hop growing season has been shown to cause reductions in hop cone yield (Hnilickova et al. 2009). Irrigation systems can help to alleviate some of the potential drought stress, but timing of water application is just as important as the amount of water hops are receiving. Hops require the majority of their water in the critical period between training and flowering for optimal vegetative growth. The hop yard is irrigated through a well-fed drip irrigation system, which delivers 3000 gal ac-1 each week, beginning in late May. Over the 14-week irrigation period, this equates to 1.54 inches of water, or 0.11 inches each week, which is well below the 23.5 inches required, adjusting for potential evapotranspiration. The goal of this project was to evaluate differences in yield, insect pests, and disease presence between plants at the Borderview Research Farm that were watered at the optimal level, and plants that were irrigated at the level sustained by the on-farm well

The interest in growing cereal rye for grain to be sold as cover crop seed, or to other value-added markets (distillers and bakers), has increased considerably across the Northeast region. As a result, farmers and end-users are requesting yield and quality information on cereal rye varieties. In 2016, University of Vermont Extension Northwest Crops and Soils (NWCS) Program conducted a variety trial to evaluate yield and quality of cereal rye. The varieties were Huron, Spooner, Abruzzi, Brasetto, Musketeer, and one variety that was not specified (VNS)

Summer Annual Variety Trial

Warm season grasses, such as sorghum x sudangrass crosses, sudangrass, and millet are high-yielding annuals that can provide quality forage in the hot summer months, when the cool season grasses that make up most pastures and hay meadows in the Northeast 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
