Effect of dung, vermi compost and biofertilizers (Psoudomonoas and Azotobacter) in a chemical less sweet corn agro ecosystem

There isn’t balanced between production and consumption when population increased due to traditional agriculture replaced to the modern agriculture. Evaluated of agriculture knowledge in genetic and biotechnology with using fertilizer and chemical pesticide can be facilitated agriculture production and also can be increased food production in increased countries but it disturb equality of ecosystem biology and also using these kind of toxic material and hormones such as nitrate and cadmium change industrial agriculture to agronomic agriculture. Here we applied randomized complete block design with three replications in a field of Karaj Azad University. We used vermicompost (1 kg/m2 for case and control)¡ Animal manure (3 kg/m2 for case and control)¡ Pseudomonas (10 ml/100gr seed for case and control)¡ and Azotobacter (10 ml/100gr seed for case and control) as a four treatment factors. The analyzed trial were sugar¡ hormones (auxin¡ gibberellin¡ cytokinin)¡ biomass¡ ear yield¡ grain fresh yield. The result showed that treatments were significant on total. Application total treatment increased trials than no application. Azotobacter and pseudomonas have more significant effect on hormones (auxin¡ gibberellin and cytokinin) than other treatments.
