The effect of seed inoculation with growth stimulus bacteria and nitrogen fertilizer on the yield and yield components of mung bean in the Ivan Gharb city

In order to effect of nitrogen fertilizer and seed inoculation with growth stimulus bacteria on the yield and yield components of mung bean, a factorial experiment was conducted in a randomized complete block design with three replications in the research farm located 15 km from the city of West Ivan in the 40 km northwest of Ilam In the 2012. Factors included the levels of nitrogen fertilizer at four levels of urea source (Zero, 25, 50 and 75 kg urea per acre) and seed inoculation with growth stimulus bacteria at four levels included (Non-inoculated of the seed as control, seed inoculation with Pseudomonas, Putida strain 186, Azotobacter strain 5 and Azospirillum lipoferum strain). The results showed that the nitrogen fertilizer and seed inoculation with bacteria had significant effect on the number of pods per plant, number of seeds per plant and biological yield. In addition to the effect of nitrogen and growth bacteria, the effect of treatments was significant on grain yield and harvest index. The highest grain yield was obtained with the consumption of 50 kg urea per hectare and seed inoculation with Azospirillum (3182 kg per ha). It seems that seed yield can be increased when seed inoculation with growth bacteria the Azospirillum in the lower urea values. Also in the experiment, all traits except thousand seed weight had positive and significant correlations with grain yield.
