seed hardiness in annual medics plays an important role in soil seed bank reserve to ensure ley farming system sustainability. to study the level of seed hardiness in annual medic (medicago scuttelata var.rabinson) at different fertilizing treatments and growing conditions (irrigated and dry farming system), an experiment was conducted at two research stations (sararod, research institute and s...
BACKGROUND AND AIMS Sulfonylurea (SU) herbicides are used extensively in cereal-livestock farming zones as effective and cheap herbicides with useful levels of residual activity. These residues can persist beyond the cropping year, severely affecting legumes in general, and annual medics in particular, resulting in reduced dry matter production, lower seed yields and decreased nitrogen fixation...
There have been a few studies on removing the seed pods in annual medics, despite its importance. To investigate the role of pod removal on seed germination, seedling growth and antioxidant enzyme activities in annual medic (Medicago scutellata L.) Under salt stress, a factorial experiment was conducted based on a completely randomized design with four replications in 2014. Salinity at 5 levels...
Ensifer medicae strain WSM1115 forms effective nitrogen fixing symbioses with a range of annual Medicago species and is used in commercial inoculants in Australia. WSM1115 is an aerobic, motile, Gram-negative, non-spore-forming rod. It was isolated from a nodule recovered from the root of burr medic (Medicago polymorpha) collected on the Greek Island of Samothraki. WSM1115 has a broad host rang...
The Special Operations Force (SOF) medic must have a public health and environmental awareness mindset while conducting operations in any AO. Whether deployed at a Forward Operating Base (FOB) or isolated outpost, the SOF medic can specifically apply two U.S. Army veterinary public health mission priorities--zoonotic disease surveillance and food/water safety. The SOF medic should be knowledgea...
medicago spp. is the most important forage crop in many regions of the world.annual medics have distinct advantages over perennial medicago. these species have fastergrowth rate in cultivation year, higher crude protein percentage, tolerance to pests and morevigorous seedlings. morphological and physical aspects of pod and seeds of annual medicsplay a major role in the tolerance of the plants t...
In order to study the effect of air and root-zone temperature on yield, yield components, nodulation and nitrogen fixation of three annual medics, an experiment was conducted in controlled environment (growth chamber) at the Faculty of Agriculture, Tarbiat Modares University in 2006. The experiment was performed as a spilt split plot with the layout of completely randomized design with three re...
