the effect of nanocomposites of iron spraying on yield and yield components of wax bean genotypes inoculated with rhizobium bacteria (rhizobium leguminosarum) in the farm conditions of gilan

aimed at reducing the consumption of chemical fertilizers on crop production and according to important role of micro-nutrients such as iron, on increase performance of these products, nanocomposites effect of iron on yield and yield components of wax bean genotypes inoculated with rhizobium bacteria during experimental factorial randomized complete block design with three replications was conducted on 2011 in the siahkal city. factors examined include iron nano-composite (non-spraying and spraying), bacteria nitrogen stabilizer (inoculated and non-inoculated) and four genotypes wax bean (sadri, talash, khomein and local gilan), respectively. analysis of variance for grain yield showed significant differences among genotypes. comparing the results showed that the interaction of three factors, figure with bacteria and nano-composite, figure khomein inoculated with bacteria and sprayed with 5.75 tons per hectare grain yield is the maximum amount to be allocated. khomein genotype spraying of iron nanocomposite with 5.73 showed the highest number of seeds per pod. in the interaction genotypes and inoculation of bacteria, khomein genotype with bacterial inoculation with 5.8 showed the highest number of seeds per pod. also in the genotypes interaction with bacteria inoculation and spray with nanocomposites, khomein genotype inoculation with bacteria and spraying nanocomposite produced the highest seed in pods with 5.87 was. according to the results mentioned the region experiments, sprayed nanocomposite iron and inoculation with rhizobium bacteria is increased seeds per pod and seed yield.
