Sunflower Variety Trial Report

Variety selection is one of the most important agronomic decisions that sunflower growers make about their crop each season, especially in Vermont where the relatively short growing season limits available choices. Sticking with a tried and true variety is often difficult because new varieties are released every year while familiar ones are discontinued, and seed companies release new traits that may or may not influence yield. To help area farmers make the best decisions, UVM Extension conducted replicated variety trials at Borderview Reseach Farm in Alburgh, VT during the 2010-growing season. The trial evaluated fourteen varieties with varying maturity dates, seed sizes, and trait information, as listed in table 2. All varieties are non-GMO hybrids. The varieties Croplan 306 and Croplan 3080 were not treated with a seed fungicide or insecticide. All others were treated with the CruiserMaxx treatment package, which contains Thiamethoxam (broad-spectrum insecticide), Azoxystrobin (fungicide), Fludioxonil (fungicide), and Mefenoxam (fungicide)

Vermont Relative Maturity Corn Silage Trial

In 2010, the University of Vermont Extension conducted an experiment to evaluate yield and quality of corn hybrids with a range of relative maturities. The goal is to document the best range of corn silage maturities to grow in this area to maximize corn yield and quality. It is important to remember that the data presented are from a single test at only one location. Hybrid-performance data from additional tests in different locations and often over several years should be compared before conclusions are drawn

Cover Crop Termination & Reduced Tillage Study

In 2010, the University of Vermont Extension conducted the second year of an experiment to evaluate the impact of cover crop termination and reduced tillage strategies on soil health, soil nitrogen dynamics, and corn silage yield and quality. The goal is to document the positive and negative aspects of each strategy so farmers can decide the best way to terminate cover crops and implement reduced tillage on their farm

Cover Crop Planting Date x Seeding Rate Trial Report

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 being 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 loss means less fertilizer needed in the spring. Farmers have asked about best practices for growing cover crops to maximize benefit to the soil, while protecting corn silage yield and quality. In particular, establishing a “last chance” planting date for cover crops is important in our region where the growing season is short and common adverse fall weather can delay planting. This study was intended to determine what planting dates and which seeding rates give the best cover crop performance into the spring

Spring Cereal Grain Forage Trials

In 2010, the University of Vermont Extension continued their research evaluating several organic annual forage models. Spring cereal grains such as oats, barley, triticale, wheat, and spelt could have the potential to provide high yield and quality feed for livestock. Spring grains are planted in mid to late April and can be harvested at various stages of development. The objective of this project was to evaluate yield and quality of spring grains harvested in the boot, milk, or soft dough stage. The overall goal of this project is to help organic dairy producers reduce their reliance on expensive concentrates through the production of a variety of high quality annul forages. In addition, we were interested in investigating the value of combining brassica forage with these cool season annuals

Warm Season Annual Forage Performance Trials

In 2010, the University of Vermont Extension continued their research to evaluate warm season annual forage systems. Warm season annual forages include grasses such as sorghum, sudangrass, sorghumsudangrass, Japanese millet, and pearl millet varieties. These grasses prefer the warmth of the summer months and generally thrive between June and August. Warm season annuals can be grazed or harvested for stored forage. Since warm season annuals thrive in hot weather they could supplement pasture during the summer slump. The summer slump is a period during the summer that cool season perennial grasses slow in growth and quality. The goal of this project was to evaluate the yield and quality of commercially available varieties of warm season annuals. In addition, we were interested in investigating the value of combining brassica forage with warm season annuals. The goal was to maximize forage yield and quality

Vermont Organic Grain Corn Performance Trial Results

In 2010, the University of Vermont Extension conducted an organic grain corn performance trial in Alburgh, Vermont, in cooperation with Borderview Research Farm and Organic Valley Farmers Advocating for Organics Program (FAFO). The purpose of the program is to provide unbiased performance comparisons of commercially available organic corn varieties. It is important to remember, however, that the data presented is from one replicated research trial in Vermont. Crop performance data from additional tests in different locations and often over several years should be compared before you make conclusions

Winter Canola Variety Trial

In 2009, the University of Vermont Extension Northwest Crops and Soils Team initiated a winter canola variety trial in Alburgh, VT as a part of the 2009-2010 National Winter Canola Variety Trial. Growing winter canola holds many possible advantages for Vermont farms. Sown in early fall, winter canola can fit well into rotations following short-season grain crops, or short-season corn. Additionally, many farms are engaged in on-farm fuel production endeavors, and canola continues to be a high-yielding oilseed crop in areas where the growing season is relatively short. However, in order for on-farm fuel production to be feasible, farmers must be able to reliably produce a high yielding crop, which is dependent on good agronomic practices including variety selection. Replicated canola variety trials were conducted with an experimental design of randomized complete blocks with four replications. Fifteen varieties were evaluated for fall stand density, yield, and oil quantity

Winter Cereals as a Multipurpose Crop

In 2010, the University of Vermont Extension continued their research evaluating winter cereals as a multipurpose crop. Winter cereal grains including barley, wheat, and triticale are planted mid to late September in the Northeast. The crops can be harvested as pasture, stored feed, or grain and straw. This study was to evaluate if the winter cereals could be grazed and then harvested for forage or grain/straw. This would allow a farmer to harvest more than one type of feed from only one planting of cereals. Overall the goal of this project is to help organic dairy producers reduce their reliance on expensive concentrates through the production of a variety of high quality annual forages. Winter cereals begin to grow early in the spring when air temperatures are in the low 40s. The growth of cereal grains begins before cool season pasture. Hence these cereals may provide early season grazing opportunities and then still be able to provide later harvested stored feed or even grain/straw
