BACKGROUND: Soil nutrition management is an important factor, which determines the plant growth. Soil fertility is determined by the presence or absence of nutrients i.e. macro and micronutrients, which are required in optimum level for crop. OBJECTIVES: Evaluate the effect different amount of nitrogen and phosphorus fertilizers in maize field under sugarcane compost consumption on leaf area index, total dry weight and seed yield. METHODS: Current research was conducted according a split block experiment based on randomized complete block design with three replications. The first factor included biological and chemical nitrogen fertilizers in 3 levels (a1: completely nitrokara, a2: 25% urea plus nitrocara and a3: 50% urea plus nitrokara) also the second factor, including biological and chemical phosphorus fertilizer in three levels (b1: phosphorus biofertilizer, b2: 25% triple super phosphate plus phosphorus biofertilizer, b3: 50% triple super phosphate plus phosphorus biofertilizer). RESULT: The results of analysis of variance indicated that the effect of different levels of nitrogen chemical and biofertilizer on plant height, leaf area index, total dry matter, crop growth rate and net photosynthesis rate were significant at 1% probability level. Also the effect of different levels of phosphorus chemical and biofertilizer in all traits was significant at 1% probability level. The interaction effect of treatments on total dry weight was significant at 5% probability level and did were not significant difference for other traits. Mean comparison of different level of main factor was observed in consumption of 50% of urea plus nitrokara and completely nitrokara treatment, respectively. Also Among different levels of subfactor the maximum and minimum amount of measured traits were observed in 50% triple super phosphate plus phosphorus biofertilizer and completely phosphorus biofertilizer treatment, respectively. CONCLUSION: Generally result of current research revealed that use of nitrogen and phosphorus chemical and biological fertilizers in field with sugarcane compost had a positive effect on measured traits of wheat and finally consume 50% urea plus nitrokara with 50% triple super phosphate plus phosphorus biofertilizer was achieved maximum amount of measured traits and can be advised to farmers.
