Abstract

An experiment was conducted in farm condition to study the effect of different PLANTING DATEs and GENESTINE CONCENTRATIONs on NODULATION and NITROGEN FIXATION of three medicgo species for two years, (2004 - 2005). Three medicago species, in clouding Medicago polymorpha, Mradiata, Mrigdulawhich are suitable for cold and temperate zone were used. PLANTING DATEs on three levels, 20th of Feb, first and, 10th of March was considered as main plot, the medicago species as sub plot and GENESTINE CONCENTRATION in 2 levels of 0 and 20 Micromole/Liter in secondary plot considered as sub plot. The experiment performed with four replications in split -split- plot base on the complete randomized blocks design. The result showed that at first year, in accordance with more suitable temperature at the beginning of growing season, the medicago species had better growth, NODULATION and NITROGEN FIXATION than the second year which unsuitable temperature at the beginning of growing season was more long. The result in according to NODULATION, NITROGEN FIXATION and all other searchable characteristics have significant difference and M. polymorpha has better ability in NITROGEN FIXATION and is better from the point of NODULATION, NITROGEN FIXATION, nitrogen percent and quantity of dry maters of root than other species. On third PLANTING DATE, because of favorite air and soil temperature, NODULATION and NITROGEN FIXATION was at highest level in Medicago species, but in first PLANTING DATE measure of NODULATION and NITROGEN FIXATION was at the lowest level in Medicago species because of the bad effect of low temperature of air and soil on growing, NODULATION and NITROGEN FIXATION. The use of genestion has a significant improving effect on NODULATION and NITROGEN FIXATION in medicago species. It represents the moderating mark of genestine and its role in declining the negative effect of low environmental temperature on NODULATION and NITROGEN FIXATION of medicago species. The study of corresponding effects of care and attendance showed that the use of genestine in the first PLANTING DATE on all species under test causes the goosing rate in NODULATION and NITROGEN FIXATION. It represents the effect of genestine to make the plant withstanding toward cold for improving NODULATION and NITROGEN FIXATION of medicago species in farming conditions.
