Management of summer grazed alfalfa
Alfalfa (<i>Medicago sativa</i>, L. cv. Arc) productivity, regrowth, and quality as affected by summer grazing management and K fertilization (560 kg K/ha) was investigated with sheep. Sheep grazed alfalfa for 2-, 4-, or 6-weeks following a 2 July hay cut when regrowth was 450 kg/ha dry matter; …

Fall harvest management of alfalfa
Alfalfa (Medicago sativa L.) harvest schedules are often interrupted by rainfall, unfavorable environmental conditions for growth, and unfavorable weather for hay curing. Interruptions in alfalfa harvest schedules can delay the final harvest until dates considered critical to winter survival. …

Combined Roles of Glandular-haired Alfalfa and Natural Enemies in Alfalfa Pest Managment in Virginia
Both alfalfa weevil, <i>Hypera postica</i> (Gyllenhal), (Coleoptera: Curculionidae), and potato leafhopper, <i>Empoasca fabae</i> (Harris), (Homoptera: Cicadellidae), remain key pests of alfalfa in Virginia. Commercial varieties of potato leafhopper-resistant (or glandular-haired) alfalfa were …

Evaluation of the Persistence of Grazing Alfalfa Varieties
<p>The use of alfalfa (Medicago scitiva L.) for grazing is becoming more common. Alfalfa is the most widely planted legume, and is one of the most nutritional forage crops available. It is proposed that alfalfa was cultivated 4000 to 5000 years ago and produces the most protein per acre of any …

Heterosis between semidormant and nondormant derived alfalfa germplasm
<p>Alfalfa (Medicago sativa L.) yield has not increased over the past 25 years in the Midwestern United States. One way to increase yield in alfalfa is through capturing heterosis. Heterotic groups are genetically distinct germplasms that, when hybridized, repeatedly produce progeny that express …

Heterosis in a broad range of alfalfa germplasm
<p>As part of an ongoing effort to implement a semi-hybrid breeding scheme Medicago sativa subsp. falcata genotypes from across the subspecies range were testcrossed to elite subsp. sativa populations to determine hybrid performance. The goal was to determine, which falcata germplasm created the …

MOLECULAR ASPECTS OF DIRECT SOMATIC EMBRYOGENESIS IN ALFALFA (MEDICAGO)
… cycMfl and cycMf2 and a cdc2 cDNA fragment from alfalfa. The full cDNA and genomic sequence of cycMfl was determined by the RACE procedure. Several cycMfl 5' end cDNA sequences, representing different allelic variants in the tetrapioid alfalfa genome, were also isolated. The expression of the …

Oats as a Companion Crop for Alfalfa: Establishment Methods
Companion crops are commomly seeded with alfalfa in the spring as an establishment method. The objectives of this research were to evaluate the performance of seedling Alfalfa (Medicago sativa L.) in terms of yield when grown with spring oats (Avena sativa) as a companion crop and to evaluate the …

CHARACTERIZATION OF SOD-INDUCED ALFALFA SEEDLING INJURY (ALLELOPATHY, ANAEROBIOSIS)
… to examine the seedling vigor of sod-sown alfalfa (Medicago sativa L.).</p><p>Seedlings grown in tilled soil had more dry matter, were taller, and had longer internodes than seedlings in sod. Node number and plant density were reduced in some experiments. Seedling vigor was not hindered by …

Mating behavior of the alfalfa weevil, Hypera postica (Gyllenhal)
The qualitative and quantitative aspects of mating behavior, the stimulus for locating and mating, and the effects of varying temperatures on mating behavior and oviposition were studied in the laboratory. Postdiapausing weevils, collected in April, and nondiapausing weevils, reared in the …

Accuracy of hay moisture sensing systems for round alfalfa bales
Moisture measurement is critical when baling alfalfa into round bales for feed. If alfalfa is too wet or too dry, it can greatly diminish the alfalfa crop’s feed quality and cause economic loss to producers. Therefore, monitoring of alfalfa moisture content while baling is critical for producers to …
