Résumé :
3 pp.<br>Due to worldwide shortages of non-dormant alfalfa seed, production opportunities and acreage have increased recently in Central Arizona. Seed production for profitability is challenging. Cultural practices differ from those commonly used in forage production. This article outlines management recommendations that may help to accomplish profitable seed alfalfa yields.

Résumé :
A test was conducted to evaluate the effect of two seed treatments on seven varieties of alfalfa. The treatments included Rhizocote, Rhizocote plus Apron plus Rovral and untreated seed. Significantly fewer seedlings emerged for the coated than the uncoated seed when planted on a pound for pound basis. First cutting alfalfa yields were neither increased nor decreased as a result of the seed treatments.

Résumé :
The handling of alfalfa and other crop seed may result in seed scarification. Scarification may not affect germination of alfalfa seed in a non - saline environment, but may decrease germination where farmer's fields are severely salt-stressed.

Résumé :
Alfalfa which is extremely salt tolerant during germination has been developed by researchers at the University of Arizona Carbohydrates were analyzed in the original parental gemiplasm 'Mesa- Sirsa' and Cycle₅Syn₂ and Cycle₈Syn₂ seed to determine why this seed could germinate in extremely saline conditions. Raffinose and sucrose were both significantly higher in the salt -tolerant germplasm compared to the parental germplasm; however, the magnitude increase of these free sugars was not sufficient to explain the increased ability of the seed to absorb water in a stress environment.

Résumé :
This experiment tested the effects of a cytokinin containing product (Dry Seed +) on CUF 101 alfalfa when applied with the seed at planting on October 24, 1996, at the rate of 1 /lb product to 100 lb of alfalfa seed. Data indicated a non - statistical yield response averaging 200 lbs an acrefrom treated fields the first cutting, valued at $11 /acre, but yields were identical the second harvest. Alfalfa quality means were very similar for both harvests. A positive net return of $9.76 /acre was noted by using Dry Seed +. More testing is suggested to confirm these findings.

Résumé :
<p> Alkali bees, <i>Nomia melanderi</i>, are native, solitary, soil&ndash;nesting bees commercially managed in southeastern Washington State. They nest in dense aggregations and are important pollinators of alfalfa produced for seed. The Washington State Department of Transportation (WSDOT) proposed safety improvements to US Highway 12 through the Touchet&ndash; Lowden&ndash;Gardena alfalfa seed growing district, an area critical to alfalfa seed production. This includes northern realignment to accommodate a wider roadway and avoid impacting any towns. Relocation of the highway will bisect se

Résumé :
Nine cycles of recurrent selection for germination salt tolerance in alfalfa (Medicago sativa L.) were compared with their parental cultivar, 'Mesa-Sirsa'. Test seeds were produced in the same season and locale. Cycle 9 and Mesa-Sirsa showed 90% and 2.5% germination, respectively, in a -1.7 MPa NaCl medium. Cycle 8 germinated more vigorously compared to Mesa-Sirsa in stressed and non-stressed environments. Selection also enhanced germination speed and radicle length. Fresh seed and one year old seed showed similar percent germination. Scarification decreased germination in a saline solution. M

The objective of this study was to determine the effect of waterlogging on germination, growth and histology of alfalfa seeds. In this study , the Hunter River of Taiwan alfalfa cultivar and Middle East were to be used for materials. The plants were waterlogging at 4th leaf , 8th leaf and booting stages for 10 days, respectively. The unwaterlogging treatment was to be control (CK). The results are showed the effects were not significant on the germination of alfalfa seeds in cultural dishes. Other

Résumé :
The assemblages of plant bugs in buckwheat and seed alfalfa in southern Manitoba mainly include the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), and the alfalfa plant bug Adelphocoris spp. While the most abundant species of mirid plant bugs in buckwheat is L. lineolaris, this species and Adelphocoris spp. are about equally common in both organic and conventional fields of seed alfalfa. Lygus lineolaris has two generations in both crops in all the study locations. Lygus bug adults can move from drying swaths of canola near buckwheat and seed alfalfa late in the growing season. H
