Abstract

In order to evaluate NODULING and NITROGEN FIXATION as well as efficiency of RHIZOBIUM JAPONICUM STRAINS in Clark cultivar of SOYBEAN under DROUGHT STRESS and also efficiency of RHIZOBIUM JAPONICUM STRAINS. Experiment performed in 2003 and 2004. Experiment conducted under split plot based on randomized complete block design with three replications. Irrigation treatments as main plots with tree levels of DROUGHT STRESS, namely low stress (85% plant water requirement), medium stress (70% plant water requirement), high stress (55% plant water requirement) and complete irrigation as control. The subplots were three strains of Rhizobium Japonicum named Helinitro, Rizoking, Nitragen and no bacteria as control were considered. The amount of irrigation water calculated with the help of plant water requirement and the atmometer. Seeds were inoculated with bacteria strains before planting. And then quantity, dry weights and sizes of nodules, NITROGEN FIXATION and also NITROGEN FIXATION yield in area determined. The results indicated that DROUGHT STRESS affected NITROGEN FIXATION. In complete irrigation as Control highest dry weight produced with application of Helinitro strain. Rizoking strain which had active nodules showed higher NITROGEN FIXATION and produced dry weight in low and medium DROUGHT STRESS. In order to access dry mater in complete irrigation using Helinitro and in DROUGHT STRESS, Rizoking were more appropriate. Also results showed that size and weight of nodules were not suitable as an index of NITROGEN FIXATION.
