Abstarct: Irrigation is one of the pillars of agriculture and the use of appropriate water has an important impact on growth and development and yield and health of crops. In the margins of large industrial societies after the use of water, wastewater is often not valued as an addition to daily life and is left in the environment or used as irrigation water. In wastewater are soluble substances that affect plant mextabolism. The use of nanomaterials, especially nanosilver, due to their biological reactions and chemical and physical soil improvers are considered in research.
Therefore, with the aim of using different levels of foliar application of nano-silver, the application of zeolite and bio-four has an effect on the cultivation of sunflower irrigated with wastewater. A factorial field experiment designed in a completely randomized design using three levels of nano-silver as described as zero, 60 and 120 ppm and the application and non-application of bio four and zeolite in 1397 in Varamin city in a field by sewage It was irrigated, it was implemented. The results showed that nano-silver had the greatest effect on the measured physiological traits such as chlorophyll a and b and carotenoids by reducing them at a concentration of one hundred and twenty.
However, these effects interacted with the use of biochar and zeolite, so that the simultaneous use of biochar reduced the effects of nanosilver and the effect of zeolite was more limited. Regarding the amount of oil, but the effect of nanosilver appeared as a stimulant and caused the amount of oil increased, but biochar and zeolite also showed an increasing effect in combination with it. Most of the treatments did not have a significant effect on the traits that affect performance and morphological traits.
