of loss varies greatly depending on placement of the fertilizer, soil pH, soil texture,
and climatic conditions after application. |

Bacterial Leaf Scorch of Landscape Trees | Bacterial leaf scorch is an important and often lethal disease of many landscape trees, particularly in the southern and eastern U.S. In Virginia landscapes it is most often observed on oak, elm, and sycamore; however, many other landscape tree species are susceptible to this disease. The bacterium that causes bacterial leaf scorch colonizes the tree's water-conducting tissue (xylem), disrupting water movement and reducing water availability to the tree. The symptoms of bacterial leaf scorch are very similar to symptoms of other problems that limit water uptake. This is why marginal leaf scorch symptoms caused by other problems, such as drought stress or root disease, are often mistaken for symptoms of bacterial leaf scorch. Laboratory identification of the causal bacterium (Xylella fastidiosa) from affected petiole and leaf tissue is necessary for positive confirmation of the disease. |

Fertilizing Cool-Season Forages with Poultry Litter versus Commercial Fertilizer | The Shenandoah Valley of Virginia and some other regions produce more manure nutrients than local crops need. This manure has traditionally been applied to row crops and overapplication has led to soil-test phosphorus (P) being well above agronomic optimum in many cases. In 2008, it was estimated that nutrient-management regulations now require that approximately 85
percent of poultry litter be applied off poultry farms, as they do not have sufficient land to beneficially recycle their manure nutrients. |

Growing Pears in Virginia | Pears are the second most important deciduous tree fruit after apple, and it has been grown in Europe since prehistoric times. Pears belong to the genus Pyrus and probably originated near the Black and Caspian Seas. French and English colonists brought pears to America and the first record of pears in the North America was in Massachusetts in 1630. Although pear is a popular fruit, it is not grown as widely as apple. Pears can be grown throughout much of North America because they tolerate a wide range of climatic conditions. |

Growing Peaches and Nectarines in Virginia | An orchard is a long-term investment and careful planning is essential to ensure economic success. Establishing and maintaining a peach planting to bearing age (three years) costs about $3,500 per acre. Mistakes made at planting often cannot be corrected; other mistakes that can be corrected could seriously jeopardize the economic success of the orchard. Because profit margins for commercial fruit plantings are small, orchards should be established only under the most favorable conditions for success. |

Pruning Peach Trees | Annual pruning is a critical management practice for
producing easily harvested, heavy crops of high quality
peaches. However, pruning is not a substitute for other
orchard practices such as fertilization, irrigation, and
pest control. Pruning practices vary slightly in different
regions of the United States, but have changed little in
the East during the past 70 years. Although pruning may
vary slightly for different varieties and localities, certain
general practices should be followed. The successful
pruner must understand the principles of plant growth,
the natural growth habit of the tree, and how the tree
will respond to certain types of pruning cuts. Improper
pruning will reduce yield and fruit quality. |

Training and Pruning Apple Trees | Proper training and pruning of trees is a major component
of a profitable apple orchard operation. Successful
pruning is an art based upon scientific principles of
tree growth and physiology and an experienced understanding
of tree response to various pruning cuts and
practices. Each tree is an individual and should be
treated accordingly. Varieties differ in growth characteristics
and response to pruning cuts, rootstocks, soil,
and growing conditions. It is important that orchard
designs, objectives, and goals be clearly defined and that
pruning principles are developed accordingly. Mediumto
high-density plantings require greater commitment to
detailed training and pruning than low-density orchards
and should not be attempted unless such a commitment
is made. |

Growing Apples in Virginia | Growing apples in the home garden can be an enjoyable and rewarding experience, but consistent production of high quality fruit requires knowledge of tree and fruit growth and a willingness to perform certain practices at the appropriate time. Virginia is on the southern fringe of the U. S. apple producing region. Most apple varieties produce the highest quality fruit when night-time temperatures are cool (less than 60°F) at harvest time. Apples grown under warmer conditions tend to be large, soft, poorly colored, and less flavorful than when grown under cooler conditions. Our warm humid summers are also conducive for infection of many diseases. For these reasons, the best Virginia apples are grown at elevations higher than 800 feet above sea level in the western part of the state. However, even apples grown in eastern Virginia usually have quality superior to apples purchased in the supermarkets. |

Training and Pruning Apple Trees in Intensive Orchards | Since the mid 1970s in the U. S., the number of apple trees per acre in new orchards has gradually been increasing. Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible by using dwarfing rootstocks that control tree size, induce early cropping, and produce large quantities of fruit relative to the amount of wood produced. |

Physiology of Pruning Fruit Trees | Woody plants are pruned to maintain a desired size and shape and to promote a certain type of growth. Ornamental plants are pruned to improve the aesthetic quality of the plant, but fruit trees are pruned to improve fruit quality by encouraging an appropriate balance between vegetative (wood) and reproductive (fruiting) growth. |

Peach and Nectarine Varieties for Virginia | Peach and nectarine are both members of the genus and species Prunus persica, and probably differ by only a single gene for skin pubescence (hairs on the fruit surface). One probably originated as a mutation of the other, but we do not know which came first. The species originated in China and was taken by traders from there into Persia, Greece, Italy, and other temperate areas of Europe. Peach and nectarine varieties may have yellow or white flesh. In Virginia different varieties ripen over a wide range of dates, from early June until mid-September. Varieties also differ in fruit size, susceptibility to some diseases and susceptibility to low winter temperatures, chilling requirements, and fruit disorders such as fruit cracking and split-pit. Descriptions of some of these characteristics are included in the next section of this publication. |

To meet this demand, regional mills import bread wheat, which comes almost exclusively from the Plains states. These imports make up approximately 30 percent of the total grain needed for the region. |

Nitrogen Management for Winter Wheat: Principles and Recommendations | Efficient nitrogen (N) fertilization is crucial for economic wheat production and protection of ground and surface waters. Excessive plant-available N produces wheat plants that are susceptible to lodging and disease with resulting decreased yields and increased input costs. The potential for enrichment of ground and surface waters with nitrates also increases with excessive N fertilizer applications. |

Nitrogen and Phosphorous Fertilization of Corn | Corn must have adequate amounts of nitrogen (N) and phosphorus (P) for profitable production. Nitrogen and phosphorus are also the nutrients that produce excessive algae growth in surface waters when concentrations increase above certain critical levels. Profitable and environmentally sensitive corn production requires that N and P be managed in an efficient manner. Economic returns from the use of these nutrients can be maximized, while the potential for surface and groundwater enrichment with N and P can be minimized with the use of appropriate technology. Available technology includes soil testing to evaluate residual soil nutrient supplies, and the use of proper application rates, methods, and timings. |

Fertilizer Types and Calculating Application Rates | Crop production has increased dramatically over the last few decades, much of which has been due to the widespread introduction of chemical fertilizers starting in the mid-1900s. Matching fertilizer application rates to crop needs is an essential component of optimizing crop production. However, different crops in separate fields will require varying rates of the major nutrients – nitrogen (N), phosphate (P2O5), and potassium (potash, K2O) – due to variations in soil types, soil test phosphorus and potassium levels, and nutrient ranges of different crops. |

Plant Propagation from Seed | Sexual propagation involves the union of the pollen (male) with the egg (female) to produce a seed. The seed is made up of three main parts: the outer seed coat, which protects the seed; a food reserve (e.g., the endosperm); and the embryo, which is the young plant itself. When a seed is mature and put in a favorable environment, it will germinate, or begin active growth. In the following section, seed germination and transplanting of seedswill be discussed. |

Winterizing the Water Garden | Water gardens require maintenance throughout the year. Preparation for the winter months is especially important for the survival of both the aquatic plants and the wildlife in and around the pond. Some plants will not tolerate winter weather and must be removed from the pond while cold-hardy plants need only to be completely immersed in the pond. Debris such as leaves and dying plants must be removed, especially if there are fish in the pond. Fall is the time to take action. Prepare the pond for the winter months by managing the plants, cleaning the pond, and monitoring the water conditions. If treated properly, many aquatic plants and wildlife can survive in the water garden for years. |

The Effect of Landscape Plants on Perceived Home Value | The value of an attractive landscape to a home’s perceived value has often been stated at 15 percent. Is this figure reliable, and what landscape features do contribute to the value of a home? How does a landscape contractor convince his/her client to spend a significant portion of a home’s construction budget on landscaping, and is this a wise investment? How can a homeowner feel justified by spending thousands of dollars to landscape a newly constructed house? Or, will thousands of dollars worth of landscaping, significantly increase the “curb appeal” of a home for sale? To answer these questions, researchers conducted a seven-state survey of attendees at consumer home and garden shows to determine consumer perspective on how plant size, type, and design sophistication in a landscape affect the perceived value of a home (Behe et al., 2005). |

Indoor Plant Culture | Select only those plants that appear to be free of pests. Check the undersides of the foliage and the junction of leaf and stem for signs of insects or disease. Select plants that look sturdy, clean, and well-potted. Choose plants with healthy foliage. Avoid plants with yellow or chlorotic leaves, brown leaf margins, wilted foliage, spots or blotches, or spindly growth. In addition, avoid those with torn leaves. Plants that have new flower and leaf buds along with young growth are usually of superior quality. |

This practice is often used after another treatment practice to disperse or eliminate runoff. In a few cases, an SOS can be used as a pretreatment to remove small amounts of sediment via a vegetated filter strip — prior to a bioretention device, for example. |

1). These systems can reduce significant quantities of
stormwater by enhancing infiltration, as well as provide
filtering and adsorption of pollutants within the
stone media and soils. Infiltration practices are part of

Getting Started in the Production of Field-Grown, Specialty Cut Flowers | Specialty cut flowers are one of the most profitable field
crops you can grow. Lynn Byczynski, editor of Growing
For Market newsletter (see Resources section),
estimates a value of $25,000 to $35,000 per acre for
field-grown cuts. The most basic requirements are at
least half an acre of open, arable land, a rototiller, and,
of course, time and effort. This publication is directed to
those new to market gardening, but commercial vegetable
growers, tobacco farmers, and young people interested
in summer income are all potential candidates.
Even grain and livestock farmers have increased profitability
in their operations by adding cut flower production.
For many greenhouse and nursery operations,
mid-summer business is slower, relative to spring. A

A shrub does not become a tree just because it grows higher than 15 feet.

Diagnosing Plant Problems | Something is wrong with your plant. What’s the cause? You can begin to determine the cause of the problem by taking on the role of Sherlock Holmes – be a keen observer and ask many questions. Diagnosing plant problems is often a difficult task. There can be many different causes for a given symptom, not all of them related to insects or diseases. The health of a plant may be affected by soil nutrition and texture, weather conditions, quantity of light, other environmental and cultural conditions, and animals, including humans. Complicating this scenario is the fact that any two of the above factors can interact to give rise to a problem. For example, a prolonged period of drought may weaken plants so that they are more susceptible to pests; this is typically observed with boxwoods. |

Home Landscape Practices to Protect Water Quality | In Virginia, we rely on reservoir systems, wells, and other sources for our freshwater.
In recent years, our previously plentiful clean water supplies have been threatened
not only by overuse, but also by contamination. Pollutants are carried down with water
soaking through the soil to the water table. Runoff (water that does not soak into the
ground) flows over the surface, often taking soil and polluting chemicals with it into
lakes and streams. |

Small Fruit in the Home Garden | As a general rule, plant selection and production area
in a home garden should be limited to what you can
properly care for. It is better to have a small, welltended
planting area rather than a large, neglected
one. Small fruits offer certain advantages over fruit
trees for home culture because small fruits require
less space for the amount of fruit produced, and they
bear fruit one or two years after planting. Success with
small-fruit planting will depend on the attention given
to all phases of production, including crop and variety
selection, site selection, soil management, fertilization,
pruning, and pest management. |

Fertilizing Landscape Trees and Shrubs | Maintenance programs should be developed for trees and shrubs in both residential and commercial landscapes. A good maintenance program includes monitoring and controlling insect and disease problems, suppressing weed competition, and making timely applications of water, mulch, and fertilizer. Tree and shrub fertilization is especially important in urban and suburban areas of Virginia where soils have been altered due to construction. These urban soils tend to be heavily compacted, poorly aerated, poorly drained, and low in organic matter. Even where soils have not been affected, fertilization may be needed as part of a maintenance program to increase plant vigor or to improve root or top growth. |

Impact of Changing From Nitrogen- to Phosphorus-Based Manure Nutrient Management Plans | Animal manures are a good source of nitrogen (N) and phosphorus (P) for agricultural crops, but they have an imbalance in their N to P ratio, so that if they are applied to meet crop N needs, then P is overapplied. For many years, manures have been applied to meet crop N needs, which has resulted in some soils containing more P than crops require, leading to environmental concerns. Regulations have been developed to limit P losses from manures and soils high in P by moving manure nutrient management from an N basis to a P basis. |

Anthracnose - A Fungal Disease of Shade Trees | Anthracnose is a generic term for a disease that occurs on many ornamental and forest trees. A number of different fungi cause anthracnose on various hosts. It occurs most commonly and severely on sycamore, white oak, elm, dogwood, and maple. Other host plants that usually show only minor symptoms of anthracnose include linden (basswood), tulip tree, hickory, birch, and walnut. Anthracnose fungi may be host-specific, as in the case of sycamore anthracnose, which infects only sycamore and not other tree species. Anthracnose fungi have similar life cycles, but require slightly different moisture and temperature conditions for infection. |

Black Root Rot of Holly | Black root rot is a fungal root disease that is a serious and extremely common problem on Japanese holly (Ilex crenata), a commonly used evergreen landscape shrub. Inkberry holly (Ilex glabra), blue or Meserve holly (Ilex crenata) are also very susceptible to black root. The disease is not as commonly diagnosed on blue holly and inkberry holly as on Japanese holly in the Virginia Tech Plant Disease Clinic. The black root rot pathogen is soil-borne and can be introduced into a landscape on infected nursery plants. Chinese holly (Ilex cornuta) and English holly (Ilex aquifolium), are resistant to the black root rot pathogen. |

Powell River Project - Growing Christmas Trees on Reclaimed Surface-mined Land | Christmas tree production can be an excellent use for reclaimed mined lands in Virginia. Most species do quite well on mine soils because they are more tolerant of infertile and droughty conditions than agricultural or horticultural crops, yet they do respond to active management. Christmas trees can be harvested within seven to 10 years, while timber crops take much longer to mature. For the person with time to invest, Christmas trees can be an ideal way to put small parcels of reclaimed mined lands to profitable use. Individual growers can conveniently maintain up to 5 acres of trees in their spare time. |

Vineyard Financial Calculator | The Vineyard Financial Calculator is an educational tool that is useful for comparing the financial performance of different vineyard operational scenarios. This tool's intended user is an individual or organization exploring the financial requirements of vineyard establishment and operation in Virginia. The tool was designed to forecast the approximate pretax annual cash inflows and outflows of a vineyard − information required to build a business prospectus. Users can modify certain input variables, such as vineyard size and labor costs, as well as outputs, such as crop level, to tailor the projections to personal expectations. The VFC is only a predictive tool; actual results could vary from those predicted due to site conditions, variances in costs, or unanticipated gains or losses. This tool was created in 2016 and originally published in 2017. The principals with which this tool operates are still valid, but the raw material prices may have changed. |

Soybean Reproductive Development Stages | Remove the soybean plant at ground level to make it easier to stage. Examine each main stem node one at a time to determine the development stage. Focus on the top four nodes that contain fully developed leaves (shown below). A fully developed leaf is one that is located immediately below a node containing a leaf with unrolled or unfolded leaflets (leaflet edges are no longer touching). The soybean crop is considered to be at a particular stage when 50% of the plants reach that stage. Listed with stage description for R1 through R6 are the approximate number of days to R7, or physiological maturity, for full season (FS) soybean planted in May and double crop (DC) soybean planted in June/July. |

Importance of Farm Phosphorus Mass Balance and Management Options | Phosphorus is a naturally occurring element that is one
of 16 elements essential for plant growth and animal
health. Research has documented that applying phosphorus
in fertilizers or manure increases crop growth and
yield on soils that are below critical agronomic levels,
as measured during routine soil testing. Although the
economic benefits of phosphorus fertilization on crop
production are well-documented, too much of a good
thing can be detrimental to the environment. Excessive
soil phosphorus is a potential threat to water quality. |

Kudzu Bug, Megacopta cribraria, a pest of soybeans | The kudzu bug (Megacopta cribraria) is an invasive pest from Asia and first appeared in the U.S. in 2009 near Atlanta, Georgia. It has since spread to 18 additional states and the District of Columbia, threatening soybean crops. Recognizable by their mottled dark green and brown coloration, adult kudzu bugs are shield bugs that exude a pungent defensive substance when disturbed. Adults and nymphs feed on plant phloem, causing both direct and indirect damage to plants. Despite initial concerns, populations only occasionally reach damaging levels, but monitoring and management remain crucial. The kudzu bug has two generations per year, with adults emerging from overwintering in early spring. Management includes chemical control with pyrethroids and neonicotinoids, biological control with parasitoid wasps and the fungus Beauveria bassiana, and cultural control by reducing kudzu patches. Here we detail the bug's distribution, life cycle, pest status, and management strategies, highlighting the importance of ongoing vigilance and integrating management tactics. |

Hinoki Falsecypress, Chamaecyparis obtusa | Hinoki falsecypress is a medium to large conifer. There are numerous cultivars that are more popular and prevalent in the nursery trade than the species. However, the species is a very beautiful conifer and well worth the hunt in garden centers or mail order nurseries. In my opinion, the hinoki falsecypress (species, not a cultivar) is more desirable than the sawara falsecypress (Chamaecyparis pisifera species, not a cultivar) since hinoki falsecypress foliage is denser and brighter green, and the bark is a brighter red-brown color. Cultivars vary in size (growth rate), foliage size and color, and form. |

Weed Management in Small Fruit Crops | For small fruit growers, weed management is one of the greatest challenges they will face to successfully grow these crops. Factors such as climate, new weed species, weed species shifts, and years of agricultural activity have come together to select for weed species that are aggressive and persistent. Without management, weeds compete with crops for light, nutrients, and water, resulting in reduced vegetative growth of the crop plant, poor fruit quality and lower yield. Stressed crops are also more susceptible to disease and insect infestations, while excessive weed growth itself creates higher humidity in the crop foliage, enhancing disease spread and inviting unwanted insects. Weed management principles for the perennial small fruit crops are similar, with the exception of strawberries in the annual system. Grapes, brambles, blueberries and matted row strawberries are considered permanent plantings in which weed management must be addressed throughout the life of the planting. When compared to annual crops, perennial culture is a greater challenge, as weeds need to be managed through all seasons and perennial weed species increase in numbers and diversity. Understanding seasonal weed thresholds, and integrating cultural and chemical management becomes even more important in the year-round culture. |

Crop Load Management in Commercial Apple Orchards: Chemical Fruit Thinning | Chemical fruit thinning is commonly practiced in commercial apple orchards to manage and regulate the number of fruit per tree (crop load), which improves fruit quality and production. In this management practice, growers typically apply several sprays of chemical thinners to orchard blocks in the spring when the fruit is small and just beginning to develop. These thinning spray applications result in the abscission, or detachment, of some of the fruit. This intentional fruit abscission or shedding is commonly referred to as “thinning.” |

Mortality of Great Rhododendron (Rhododendron maximum) in Virginia | Since 2015, Extension specialists from Virginia Tech (VT) have visited and collected plant and soil samples from several large areas of dying great rhododendron (Rhododendron maximum) in Virginia’s mountainous regions. In 2016 VT specialists met with Virginia Department of Forestry, US Forest Service personnel, and other experts to revisit some of these sites. No consistent cause of this mortality has yet been identified. It is possible that a variety of factors are stressing the rhododendrons in these areas to a point where opportunistic pathogens or insects can successfully attack and kill them. The following information summarizes our observations and diagnostic results from four separate great rhododendron mortality sites in Virginia. This information is not equivalent to a research study, which would also include samples taken from healthy great rhododendron for comparison; however, we are confident that we have ruled out two diseases that are frequently mentioned both online and anecdotally as a cause of this mortality, specifically Phytophthora root rot and Botryosphaeria dieback. |

Sampling Tall Fescue for Endophyte Infection and Ergot Alkaloid Concentration | Endophyte-infected tall fescue is the dominant forages in Virginia. As such, it is imperative to manage this important forage resource wisely. Ergot alkaloids produced by fescue’s fungal endophyte create challenges to accomplishing this. Tests for endophyte presence and alkaloid levels are important management tools that producers can use to minimize alkaloid consumption and the negative impacts of on animal performance. Consistent testing methods are important for adequately assessing alkaloid levels and for making comparisons among pastures over time. These results then can be used to develop a custom grazing strategy to avoid severe incidences of fescue toxicosis. Repeated testing during a grazing season can help determine possible benefits to pasture renovation or addition of legumes. Similar to testing forages for nutrient concentrations and devising a winter feeding and supplement plan, testing fescue-based pastures for endophyte infection level and for ergot alkaloid concentrations at various times during the year can facilitate management to reduce alkaloid consumption and also help determine if further mitigation is needed. |

Consider Your Whole System: Nitrogen and Sulfur Leaching Potential in Virginia | Jun 25, 2018 | SPES-39NP | |||
Consider Your Whole System: Nitrogen and Sulfur Leaching Potential in Virginia | Early summer often means locally heavy and sporadic rainfall as thunderstorms deliver intense rains, and 2018 appears to be no different with many areas in eastern Virginia receiving 3+ inches of rain in a few days (Figure 1). These storms also often coincide with the timing of sidedress nitrogen (N) and sulfur (S) applications on corn. While some rainfall after sidedress is very beneficial to facilitate N movement into soil, heavy rain (2+ inches) often leaves us wondering how much, if any, of that recently-applied N remains and if additional N is needed. |

Chemical Options for Defruiting Young Apple Trees | Apple trees can produce plenty of fruits in the first two years of planting. If kept on the tree until harvest, these fruits would have a negative effect on tree growth and structure. Defruting newly planted and young apple trees (e.g., 2nd and 3rd leaf), particularly those on dwarfing rootstocks, allows the trees to fill their allotted bearing space and become structurally capable of bearing a decent crop by the fourth and fifth year. Although defruting can be achieved manually by removing flower clusters and small fruitlets, several chemical options can make defruting much faster and less labor-intensive. This publication aims to provide information about the rates and application timing of chemical materials apple growers can use to effectively defrut young trees. |

Hydroponic Production of Edible Crops: Planning for the Market | According to the 2017 Census of Agriculture, U.S. greenhouse vegetable farms more than doubled from 2012 (USDA 2019). Virginia fell within the top 10 states for acreage of vegetables and berry crops grown under protected culture. Protected culture includes greenhouses and structures like high tunnels. With close to two and a half million square feet devoted mostly to tomatoes, vegetables, herbs, and strawberries, the value of Virginia greenhouse sales in 2017 was over 31 million dollars! A lot of this increase in square footage was due to the addition of large operations coming into Virginia. |

Aerial multispectral imagery for high-throughput mapping of spatial corn yield potentials. | Drone-based spectral imaging is a nondestructive approach for estimating corn grain yield efficiently prior to harvest. Such spatial estimations if done early in the season could help growers to identify lower performing areas of the field. This will guide them to adopt prompt, precise and cost-effective crop management operations (e.g., irrigation, fertilizer or fungicide applications) in the same season or before/during next cropping season. Pre-harvest yield estimates would help in better planning and allocation of harvest, storage, and sales resources for higher profitability and crop value. This article summarizes a recent exploration on drone-based multispectral imagery to estimate grain yield potential of corn. |

The publication covers the basics of how septic systems operate, both in the septic tank and the drainlines. It also provides information about soil evaluations, including who can evaluate the soil and reasons that the soil must be evaluated. The publication includes information on how much space both the septic tank and the full septic system will take up. Finally, the publication discusses set-back distances that are required for the septic system, the home and various other features that may be found on the property. |

Prohexadione Calcium or Seed Aging? | Peanut is a “cash” commodity for Virginians and most farmers grow this crop for certified seed. Seed quality and germination in particular are, therefore, very important. Even though the 2022 results were inconclusive, potential for prohexadione calcium to reduce germination and increase abnormal seedling production was clearly suggested by these data. The inconclusiveness could have been the result of a combination of factors, other than PC, affecting seed quality during storage. A differential response of the cultivars to both, seed aging and PC, was clearly suggested by our preliminary data. Evidence that PC may affect the seed quality, through seed weight, was also notable from the 2022 tests. |

Faba Bean: A Multipurpose Specialty Crop for the Mid-Atlantic USA | Faba bean (Vicia faba L.), also known as fava bean, broad bean, horse bean, or Windsor bean, is a leguminous crop used as food, feed, forage, or cover crop in different parts of the world. This crop can be used for food, feed, and as a ground cover crop. It is highly nutritious and has high protein content, the second after soybean when comparing with the common grown legumes including, dry beans, lentils, peas, cowpeas, and chickpeas. The high protein content makes faba bean an excellent source for plant-based foods, like meat and milk. Compared to the other cool-season legumes such as pea and lupin, faba bean can attain and fix substantially more nitrogen from the atmosphere to soil. Because of temperature increase during summer, a winter crop can ensure cropping system diversification while minimizing the negative effects of summer heat on yield and economic return, and this crop can potentially be faba bean. A USDA-funded project at the Virginia Tech’ s Tidewater Agricultural Research and Extension Center (TAREC) in Suffolk, VA, is focused on introduction of faba bean as a winter seed crop with multiple benefits for the Mid-Atlantic cropping systems. The project includes collaborators from the University of Maryland, University of Delaware, North Carolina State University, and University of Georgia, in addition to the Virginia State University and Virginia Tech. Started in 2023 and lasting until 2027, the project will address objectives related to cultivar development through breeding, genetics and physiological strategies, identification of the best agronomic practices to maximize yield and economic return, economic and marketing logistics, and consumer acceptance. As the results became available, the PI will provide updates on this new crop for the region. |
