Abstarct: Many environmental and economical problems in urban waste disposal and increasing reduction of countries soil organic matter have caused more production and also application of fertilizer products from urban waste. Urban waste compost humus in the extraction and use of agricultural land can be millions of annual production of various crops and garden added. Another organic fertilizer is humic acid. Humic acid absorption capacity of nutrient is fast. Accordingly, this study examined the effect of compost application humic acid on qualitative and quantitative traits in maize crop 90 - 91 Shahrood University Agricultural Research Farm was located in Bastam.The experimental Factorial baxsed on randomized complete block design with three replications was applied. In this project, effects of the two factors, humic acid and vermicompost,in four and three levels were investigated respectively. The traits including yield, plant height, seed weight, number of grain rows per ear, number of rows per ear, grain weight, biological yield, respectively. The results showed that compost application on all traits except number Kernel rows per ear and harvest index had a significant positive impact that the increasing use of compost Traits also increased. Also, it was observed that the treated humic acid also on all Measured traits except grain weight, number of grain rows per ear and harvest index had positive and significant impact So that the lowest and the highest yield was measured using no and 2400 ml humic acid.
