to study the physiological and morphological relationships of two clover species affected by herbicides, pursuit experiment in a factorial based on randomized completely design with 3 replications at the damavand in 2012. the first factor consisted of two species of trifolium pretense l. and trifolium alexandrinum l. and the second factor consisted of three levels of herbicide pursuit (0, 0.5, ...

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...

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...

in order to evaluate intercropping of summer savory (satureja hortensis l.) and persian clover (trifolium resupinatum l.), an experiment was conducted at agricultural research station of ferdowsi university of mashhad in 2004 growing season. treatments were sole cropping of persian clover (eight rows), double-row intercropping of persian clover and summer savory with 27, 40 and 80 plants.m-2 (e...

objective: returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. in fact, the plant residues can affect soil conditions such as ph and important role in soil fertility and cycling of elements in the soil may have. in addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...
