Plant nutrients might affect the activity and bioavailability of heavy metals in the soil –plant environment thus their accumulation in the plant. Little is known about the effect of nitrogen fertilization on cadmium (Cd) uptake by alfalfa “Medicago sativa”. This work aims to characterize the oxidative status, the physiological stress parameters and the Cd uptake in alfalfa « Medicago sativa » ...

The study evaluated the response of alfalfa (Medicago sativa L) to arbuscular mycorrhizal fungi (AM) species Glomus intraradices and Sinorhizobium meliloti, strain 1021 regarding the dry biomass accumulation, mycorrhizal fungi colonization, nodulation and nitrogen fixation activity. Alfalfa plants were grown in a glasshouse until the flowering stage (58 days), in 4 kg plastic pots using leached...

Our objective was to understand how mineral N availability alters accumulation of N reserves (nitrate, amino acids, soluble proteins and vegetative storage proteins known as VSP) in alfalfa (Medicago sativa L. cv Lodi) taproots. The effects of variation in NH4NO3 availability were followed by studying non-nodulated plants grown under hydroponic conditions during 21 days with (i) different N sup...

This study aimed to evaluate the quality of Arbuscular mycorrhizal fungi (AMF) produced by different nutrient fortification techniques in increasing adaptation and productivity alfalfa (Medicago sativa L.) at greenhouse scale. The research design was a completely randomized (CRD) with 5 treatments 10 replications. treatment based on types AMF product, including without as control (P0), superior...

A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population develo...

With more than 65% of agronomic crops under no-till in Pennsylvania, herbicides are relied on for weed management. To lessen the environmental impact and selection pressure herbicide resistance, we conducted a 9-yr experiment to test reduction practices dairy crop rotation at Rock Springs, PA. The included soybean [Glycine max (L.) Merr.]–corn (Zea mays L.)–3-yr alfalfa (Medicago sativa L.)–can...

The meat goat industry is growing rapidly in the U.S., particularly on small farms. There are a diversity of forage types and qualities used in meat goat production systems. Seventy-two Boer goats were used to evaluate weight gain and carcass parameters when growing goats were finished on alfalfa (Medicago sativa L.; ALF), red clover ( Trfolium pratense L.; RCL), or orchardgrass (Dactylis glome...

Alfalfa (Medicago sativa L.) is one of the most important perennial forage crops on cultivated fields in the world. Agronomical interests for this crop are based on its numerous advantageous characteristics such as (1) high yield potential and suitable feeding value, (2) different methods of utilisation green mass, hay, silage, greenchop, briquette, pellets, etc., (3) favourable environmental i...

Amylase was found in high activity (193 international units per milligram protein) in the tap root of alfalfa (Medicago sativa L. cv. Sonora). The activity was separated by gel filtration chromatography into two fractions with molecular weights of 65,700 (heavy amylase) and 41,700 (light amylase). Activity staining of electrophoretic gels indicated the presence of one isozyme in the heavy amyla...

The bacterial leaf spot described here was first recognized on Turkestan and Grimm alfalfa (Medicago sativa L.) in two locations at Madison, Wis., in August 1930. The alfalfa in both instances was in cultivated experimental rows and had been repeatedly splashed bywatering with a garden hose. In October 1931 the disease recurred under similar circumstances at one of these locations, but with the...
