Effect of time factor, spray feeding of Copper and Iron in the relation between the number of bacterial root nodules and leaves of Bean

Abstract

pot experiment was carried out during the spring season in the year 2008 to investigate the effect of the time factor, spray feeding of copper and Iron on the relation between the number of nodules and leaves of Beans. The statistical analysis showed that spray feeding of copper and Iron exceed significantly on the control treatment (water spray feeding), also, the spray feeding of Iron after 20 days of seeding excelled significantly on the spray feeding of Iron after 30 days of seeding, as well as the Spanish type of seed surpassed significantly on the Brazilian kind of seed in the number of root nodules and leaves of bean. On the other hand the studied characteristics appeared positive significant correlation coefficient (r=0.899). The interaction (overlap) treatment Cu1×S2×Fe1 recorded the highest values in both root nodules and leaves of bean by 9.00 nodule/ plant and 59.33 leaves/ plant, respectively.
