Bio fertilizers contain a sufficient number of one or more species of beneficial microorganisms and nutrients from the soil are able to convert unused usable form. In order to evaluate the effect of manure into bio-fertilizer and seed inoculation with nitrogen-fixing on agronomic traits of grain corn KSC647 cultivars, factorial experiment in a randomized complete block design with four replications was conducted during 2012-2013 in the College of Agriculture, Islamic Azad University of Varamin. The first factor manure: M1: to use 30 tons of manure per hectare of manure and M2: Non-application of manure, Second factor bio-fertilizers Azotobacter strains (Azotobacter chroococcum): Az1: seed inoculation with Azotobacter and Az0: non-inoculated seed with Azotobacter and the third factor bio-fertilizers Azospirillum strains (Azosprillum brasilense): As1: seed inoculation with Azospirillum and As0: non-inoculated seed with Azospirillum bio-fertilizer. The results showed that the highest grain yield, biological yield, grain weight, harvest index, number of seed per ear from animal manure and seed inoculation treatments combined with Azotobacter and Azospirillum was obtained. Specify the use of bio-fertilizers with manure saves 50% of the nitrogen fertilizer. It seems that excess nitrogen from manure improves the vegetative growth at the beginning and in the middle of nitrogen-fixing bacteria able to stabilize the soil nitrogen available to the plants. Synergy of these two factors has led to the growth of nitrogen in the plants, and thus achieved the highest yield. Manuscript profile

In order to evaluate the effect of micronutrients (Fe, Zn and Mn) on the quantity and quality of the Stevia, an experiment was conducted in during 2014 at Research Greenhouse of Faculty of Agriculture, Islamic Azad University, Varamin branch. A randomized complete block design with three replications was used. Treatments included: 1-Control, 2-Foliar application (9% Fe water-soluble), 3- Foliar application (6% Fe water-soluble), 4- Foliar application (9% Fe water-soluble)+ Zn, 5- Foliar application (6% Fe water-soluble)+ Zn, 6-Foliar application (9% Fe water-soluble)+ Mn, 7- Foliar application (6% Fe water-soluble)+ Mn, 8- Foliar application (9% Fe water-soluble)+ Zn+Mn, 9- Foliar application (6% Fe water-soluble)+ Zn+Mn. Results showed a significant effect of Foliar micronutrients on shoot length, Internode length, root dry weight, leaf dry weight, soot dry weight, Stevioside, Rebaudioside, Glycoside, chlorophyll a, chlorophyll b, total chlorophyll, chlorophyll b/a, Fe, Zn and Mn content, but the effect of Treatments on P and Ca content is not significant. The Best Results in Foliar application (9% Fe water-soluble) + Zn+Mn treatment was obtained. The impact on the amount of phosphorus and calcium treatments were not significant. Because the micro-nutrients applied as foliar application is sent, an increased impact on soil phosphorus and phosphorus absorption and thus no plant phosphorus content is also due to the lack of elemental calcium treatments and applications by spraying, can have no effect on the absorption of calcium soil. Most of the glycosides in the treatment of iron (nine percent soluble in water) + Zn + Mn and lowest in control 7.55 and 3.94 respectively with an average of dry matter was obtained. Most of the shoot in the treatment of iron (nine percent soluble in water) + Zn + Mn and lowest in control respectively 81 and 58 cm respectively. Fe + Zn + Mn combination treatment compared to other treatments bigger share of Stevia in the lengthening of internodes were at least internode length, with an average of 3.03 inches was in control. Lowest Steviosid with an average of 2.25% of dry matter in the Amdo control Fe + Zn + Mn combination treatment compared to other treatments had a bigger share in the increase in the Stevia plant Steviosid. The highest Rybvdyvzyd in the treatment of iron (nine percent soluble in water) + Zn + Mn and iron treatment (six percent soluble in water) + Zn + Mn with an average of 2.63 and 2.53 percent of the dry matter and least control it. In between treatments, foliar iron (not water-soluble iron content) + Zinc + foliar fertilizer spray six thousand four hundred manganese fertilizers more effective than other treatments the traits were measured.
