Abstarct: In sustainable agricultural system using the organic components less damage to environment such as Humic Acid. It cam increase water and mineral material absorption by semi – Normic activity and also increasing the function result in plants. Experiment was conducted as a split-plot baxsed on randomized complete block design with three(s) iteration performed in research agricultural center of shahrood in order examine the affection of Hyomick Acid in both way for using in soil and spray solution upon quantity function and quality properties of sunflower respect Hybrid in dry condition : test cure include 3 dry stress level : observer(100% needed water)middle stress (80% needed water ) and server stress (60% needed water) mentioned as a main cure also fire level of Hyomik acid include :observer clack of using ,spray solution with 1/5 , 3 kilogram concentration in 1000 loter water and soil using with 15 and 30 kilogram in Heetar as a minor agent is considered. Results show that, using the Hyomic Acid in both way(using in soil and spray Acid) have meaning significant on height of bushier diameter of level, seed function , biological function , amount of collrophil a and percent of phosphor and potassium l elements in seed by increasing the amount of Hyomick Acid concentration also increasing the measurable properties. Also it observed that dry stress cues to decrease seed and biological yield, seed weight, head diameter, stem diameter, grain phosphorus, collorophil b and carotenoid. function in this test the hyomic acid contraction and dry stress upon oil percent have meaningful affection note that , the oil amount in crease by dry stress .result show that using the hyomic acid in both way(using in soil and spry solution) in high enocentration cause to slightly decrease mis- affection of dray stress on sunflower .
