1. To study the potential for complementarity in nitrogen acquisition from different soil depths, we injected an isotope tracer ( 15 NH 4 Cl) at 5 and 20 cm depths in plant communities containing Achillea millefolium L. and Festuca ovina L. or Phleum pratense L. and Trifolium pratense L. in monocultures and two-species mixtures. 2. In monoculture, Festuca and Phleum took up tracer at 5 and 20 c...

in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

Rhizobium tropici CIAT899 induced chlorosis in the leaves of its symbiotic hosts, common bean (Phaseolus vulgaris L.), siratro (Macroptilium atropurpureum Urb.), and Leucaena leucocephala (Lam.) de Wit. Chlorosis induction by strains CIAT899 and CT9005, an exopolysaccharide-deficient mutant of CIAT899, required carbon substrate. When the bacteria were added at planting in a solution of mannitol...

Some plant species belonging to Trifolium L. genus are a source of isoflavones considered to exert phytoestrogenic activities. The aim of the present study was to examine the effects of standardized extract obtained from aerial parts of Trifolium medium L., in comparison with the extract of Trifolium pratense L., on the development of estrogen deficiency-induced osteoporosis in rats. Both Trifo...

Oilseed rape (OSR; Brassica napus ) is a globally important crop which increasingly under pressure from pests, pathogens and weeds. We investigated the potential of achieving multifunctional protection benefits by intercropping oilseed with legumes. A field experiment was conducted in winter intercropped annual frost sensitive legumes berseem clover ( Trifolium alexandrinum or spring faba bean ...

No information is available about the effect of Egyptian radish (Raphanus sativus) and clover (Trifolium alexandrinum), sprouts (ERS and ECS) on diabetic animals. To clarify the effects, the influence of ERS and ECS on blood sugar and lipid metabolisms was investigated in normal and streptozotocin-induced (STZ) diabetic rats. Rats were fed a semi-modified diet containing 10% of ERS or ECS ad-li...
