cultivation of annual medics is a way to increase producing of forage with a better quality, to increase the quantity of producing forage in low yield drylands, and to assisst establishing pasture. this study was conducted in order to investigate the adaptation and determination of quantitative and qualitative characteristics of three species of annual medics. the experimnet was conducted in a ...
ABSTRACT- Annual Medicago species (Medicago spp.) are native to the Mediterranean region and widely used in fields and pastures in Iran. There are several methods of sowing annual Medicago species, each with different effects on the performance. However, there is currently no sufficient information about the appropriate methods for sowing Medicago species. In order to evaluate methods of sowing...

The nutritive value of the annual alfalfa (Medicago rigidulla, Medicago polymorpha and Medicago scutellata) species harvested at flowering stage was assessed by chemical composition, in vitro dry matter and nitrogen digestibility, in sacco dry matter and nitrogen degradation (0, 8, 12, 24, 48 and 72 h) and palatability (short-term intake rate, STIR) methods. Mean values of the chemical analysis...

this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Ensifer medicae WSM244 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago species. WSM244 was isolated in 1979 from a nodule recovered from the roots of the annual Medicago polymorpha L. growing in alkaline soil (pH 8.0) in Tel Afer, Iraq. WSM244 is the only acid-sensitive E. medicae strain that has been seque...
Allelopathy is one of the main factors limiting the plants growth. The present study investigated the effect of aqueous extract of leaves and fruit of Artemisia sieberi that is an important species for rangeland rehabilitation on seed germination and seedling growth of three alfalfa species (Medicago sativa cv. Nikshahri, Medicago polymorpha and Medicago scutellata cv. Robinson) in laboratory ...
Effect of different genestein concentrations on nitrogen content and nodulation in annual medics was studied this research was done under controlled environmental condition at the 20/25 oC day/night air temperatures and 5 oC low root zone temperature. Three annual medics species (Medicago polymorpha, Medicago radiate, Medicago rigidula) adapted to cold and temperate zones and 5 genestein leve...
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...
