Maze is widely cultivated in many countries due to capabilities such as adaptation to various climatic conditions, drought tolerance, high performance, ability to be in different frequencies, full adoption of mechanization and the multiple uses. In order to investigate the application effect of mycorrhiza fungus and various amounts of the phosphorus fertilizer levels on the quantitative and qualitative features of Zea mays Single Cross Karoon, an experiment was conducted as factorial in randomized complete blocks design with two levels of mycorrhiza fungus application and non-application and four amounts of phosphorus fertilize with three replications, in north of Khouzestan in 2013 cropping year. The obtained results of variance analysis showed that through adding mycorrhiza fungus the grain yield, biological yield, bush harvesting index, grain number in row and bush height, at one percent level and the traits like bush height, one thousand-grain weight and grain protein was significant at five percent level and row number in grain was not affected by mycorrhiza. Also, A2 treatment (the use of mycorrhizal inoculation) showed higher yield with the average protein percent 10/83 comparing to treatment A1 (lack of using mycorrhizal inoculation) with average 10/59. The effect of phosphate treatment on bush height, one thousand-grain weight, grain yield, grain number, biological yield, bush harvesting index and protein was significant at one percent level and was not significant at row number in maize.
Keywords: Quantitative and qualitative characteristics, Phosphorus, Mycorrhiza.
