Twenty-four lactating Holstein dairy cows (12 first lactation and 12 multiparous; day in milk = 11 ± 5 days) were allotted to a randomised complete block design in a 2 × 3 factorial with four replicates per treatment to evaluate the effects of two methods of alfalfa feeding (dry and reconstituted to achieve a theoretical dry matter (DM) content of 350 g/kg) and three geometric mean (GM) particl...

The Arecibo Legacy Fast ALFA (ALFALFA) survey is an ongoing second generation blind extragalactic HI survey exploiting Arecibo’s superior sensitivity, angular resolution and digital technology to conduct a census of the local HI universe over a cosmologically significant volume. As of mid2007, ∼4500 good quality extragalactic HI line sources have been extracted in ∼15% of the final survey area....

Aphanomyces euteiches Drechs. causes economically important root rot diseases of several legume species when wet soil conditions prevail. This soilborne oomycete pathogen causes severe root rot damage to pea (Pisum sativum L.), alfalfa (Medicago sativa L.), snap bean (Phaseolus vulgaris L.), and red clover (Trifolium pratense L.) (12,21,22,24,25,29). A. euteiches was first described as an impor...

The sericultural productivity could be effectively modulated by enriching the silkworm diet with exogenous factors like alfalfa, a widely used homeo medicine. The minimum effective concentration (MEC) that promotes optimal larval growth, activates metabolism and improves silk production has been determined in Bombyxmori, by a stepdown process starting from higher concentration (5%) to a lower c...

Alfalfa (Medicago sativa L.) is a highly attractive plant host to Lygus spp. and is used as a trap crop in California organic strawberries to influence the dispersion and dispersal of these pests, particularly Lygus hesperus Knight. The abundance and distribution of Lygus spp. nymphs between two trap crops separated by 50 strawberry rows was analyzed in 2008 and 2010. Nymphs demonstrated a bimo...

Drought resistance is an important breeding target for enhancing alfalfa productivity in arid and semi-arid regions. Identification of genes involved in drought tolerance will facilitate breeding for improving drought resistance and water use efficiency in alfalfa. Our objective was to use a diversity panel of alfalfa accessions comprised of 198 cultivars and landraces to identify genes involve...

Some plants can tolerate and even detoxify soils contaminated with heavy metals. This detoxification ability may depend on what chemical forms of metals are taken up by plants and how the plants distribute the toxins in their tissues. This, in turn, may have an important impact on phytoremediation. We investigated the impact of arbuscular mycorrhizal (AM) fungus, Glomus intraradices, on the sub...

A slaughter experiment was conducted to determine the effects of alfalfa particle size on rumen morphology and performance of lambs. Twenty-four Balouchi lambs aged 21 days (9.1 ± 1.1 kg) were randomly fed control (diet without alfalfa hay; CON) and mixed rations containing 15% finely ground (FINE; 2 mm) and 15% coarsely chopped alfalfa hay (LONG; 3 to 4 cm). After a 63 days feeding period, nin...

The experiment was carried out in 1999-2001 at the University of Agriculture in Krakow (Poland) to study the capacity of nine crops (red beet, field pumpkin, chicory, bean, barley, white cabbage, maize, alfalfa, and parsnip) to remove cadmium (Cd), lead (Pb) and zinc (Zn) from different soil horizons (0-20, 20-40, 40-60 cm). The content of exchangeable Cd, Pb, and Zn decreased along with the de...

Birdsfoot trefoil is a high-quality forage recommended for irrigated perennial pastures, either in mixtures with grasses or in pure stands. In this bulletin we report on the forage nutritive value of pure stands of birdsfoot trefoil harvested at 6week intervals, and compare it to alfalfa harvested at the same intervals. We found that the digestibility of the two forages was similar, but that al...
