Effect of iranian common biofertilizers inoculation on growth and uptake of elements by corn (single cross 704) and Bean (Phaseolus vulgaris L. ) at green house condition

The use of native biofertilizers in Iran requires quality control of this type of fertilizer. Quality control of biofertilizers is a multi-step process and greenhouse testing is the most important step in using fertilizer. Accordingly, in order to investigate the effects of inoculation of conventional Iranian biofertilizers on corn and beans, a greenhouse experiment was conducted in a completely randomized design with 5 treatments (control, Barvar 2, Supernitroplus, Nitroxin and Biosuperphosphate) and 4 replications. The results showed that the use of biofertilizers had a significant effect on beans and corn. In Bean plant, the total fresh weight for Barvar2 treatment with an average of 67.10 g was the highest. Comparison of mean nitrogen concentration showed that Nitroxin biofertilizer treatment increased by 40.5% compared to control. In maize, nitrogen concentration was highest for Biosuperphosphate and Barvar 2 treatments with 0.91% and 0.81%, respectively. The chlorophyll index for Barvar 2 and Biosuperphosphate is the highest with an average of 4.945. Also, the comparison of the mean showed that the concentration of iron in the root of maize in the biosuperphosphate treatment (832.7 mg/kg -1 ) was the highest and no statistical difference was observed between Barvar 2 and Nitroxin and control treatments.
