Effect of fertilizers application and plant growth promoting rhizobacteria on Forage yield in maize (Zea mays L.)

In order to study the effect of organic food systems، fusion، increased chemical and bacteria growth (PGPR)، on the growth stages of corn silage single cras 704 in order to reduce consumption of chemical fertilizers، improve soil and plant nutrition improvement، in the year 2010 Farm Research، Islamic Azad University of Arak as factorial experimental design based on randomized complete block with three replications was performed. To test treatments، inoculated seeds by stimulating the growth of bacteria in four levels، B0= rhizobiom، azsprliom، Azotobacter and Pseudomonas، B1=rhizobiom، azsprliom and Pseudomonas، B2= rhizobiom، Azotobacter and Pseudomonas، B3= azsprliom، Azotobacter and Pseudomonas and use of nitrogen fertilizers،nitrogen، phosphorus and potasiom four levels، A0= no consumption، A1= 1/3 the recommended amount، A2=2/3 the recommended amount، A3 = 100 % of the recommended amount، were applied. The results showed that chemical fertilizer on the characteristics such as plant height، number of leaf، number of grain rows، number of grain per ear and forage yield level was statistically significant in a percentage. Also، different levels of biological fertilizers on the characteristics such as: ear leaf length، number of seeds per row، plant height and forage yield made a positive impact on the statistical level was a significant percentage.
