Abstract

Background and objectives: One of the most important microbial fertilizers is phosphate microbial fertilizers, it can be prepared in powder or granular form, which, after mixing the constituents, should be used for gentle heating (40-50 degrees Celsius) to dry the fertilizer, such conditions will eliminate the bacteria that are added to the carrier. The use of temperature resistant Phosphate solubilizing bacteria in granular phosphate fertilizers is one of the strategies to overcome the limitations of these fertilizers production. Materials and Methods: In this research, the efficacy and Effectiveness of phosphatic microbial fertilizers prepared from two temperature resistant Phosphate solubilizing bacteria (RPS9 and RPS7) and a non-temperature resistant bacterium (PS4) in the basal formulation of rock phosphate (45 g), sulfur (15 g) and bagasse (30 g) was evaluated on corn S. C. 704 cultivar. Experiments were conducted in a completely randomized design with regard to control treatment (without microbial fertilizer and chemical fertilizer), triple super phosphate fertilizer treatments at 50% and 100% fertilizer recommendation, with bacterial treatments (PS4, RPS7 and RPS9) in three replications Done. The irrigation of the pots was carried out through weighing at 0. 8FC. Results: The results of greenhouse experiments showed that the application of phosphatic microbial fertilizers in corn, on fresh and dry weight of the whole plant, absorption of phosphorus, potassium, iron and zinc in the root and shoot part had a significant effect. The PS4 microbial fertilizer application had the highest amount of phosphorus absorption and in this regard was treated with chemical treatments SPT (100% and 50%) in same group and increased the rate of absorption of phosphorus by 25. 07% compared to negative control and 23. 49 % Compared to control without carrier (No Carrier). In potassium parameters of the plant were also treated with SPT fertilizer (100%) and PS4 microbial treatment led to highest potassium uptake with average of 585. 685 and 511. 343 (mg / plant), respectively. Microbial treatments of PS4 and RPS9 in the supply of phosphorus and potassium of the corn plant were well treated with triple super phosphate. RPS9 of microbial fertilizer in the Fe parameter and RPS7 in Zn parameter had the highest performance. Conclusion: Inoculation of microbial fertilizers containing plant growth promoting bacteria has led to the colonization of these bacteria in the plant's rhizosphere, and we have seen the incremental effects of measured parameters. PS4 bacterial treatment was similar to triple super phosphate treatment (100%) and RPS9 treatment was similar to triple superphosphate (50%). RPS7 has lower performance. Among the two newly-released temperature resistant isolates, both of which are Pantoea agglomerans, it seems rational to use RPS9 for this purpose.
