This research was carried out as strip blocks in a randomized complete block design with three replications. The first factor, contained different amounts of chemical and biological nitrogen fertilizer at 3 levels 1- all through nitrocara, 2- 25% urea + nitrocara, 3-50% urea + nitrocara and the second factor, consisted chemical and biological phosphate fertilizer in 3 levels 1- all through barvar-2 phosphate bio-fertilizer, 2- 25% triple superphosphate + barvar-2, 3- 50% triple superphosphate + barvar2. The results showed that nitrogen and phosphorous fertilizer had a significant effect on number of rows per ear, number of seeds per row, 1000 grain weight, grain yield, biological yield, harvest index and protein yield. Interaction effect of nitrogen fertilizer and phosphorus fertilizer on grain yield, biological yield, 1000 grain weight and protein yield was not significant but had significant effect on other traits. The maximum grain yield and protein yield belonged to 50% urea + nitrokara and 50% triple superphosphate + barvar2 by 7476 and 830 kg.ha-1 respectively. The minimum grain yield and protein yield were observed for treatment of using all through nitrocara and barvar2 by 4401 and 329 kg ha-1, respectively. In generel, the results showed that in conditions of application of sugarcane compost, the use of fertilizer through biological and chemical increased the quantitative and qualitative maize yield and the maximum effect obtained on 50% urea + nitricara and 50% superphosphate triple + barvar-2.
