Abstract

An experiment was conducted to check the effect of foliar spray of nano and organic fertilizers and a growth regulator on vegetative growth of sunflower crop. Sunflower (Helianthus annuus L.), Spanish class (Viki) was cultivated from march 2013 to June 2013 at College of Agriculture, University of Wasit, Iraq. Three levels of nano silver viz., control, 25 and 50 mL/L; three levels of organic fertilizer (Algastar) viz., control, 0.75 and 1.5 g/L and three levels of salicylic acid viz., control 60 and 120 mg/L were foliar sprayed at 65 days old sunflower crop. Results showed that foliar spray of 50 mL/L of nano silver, 1.5 g/L of organic fertilizer (Algastar) and 120 mg/L of salicylic acid have a positive effects on average number of leaves, number of branches and leaf contents of carbohydrate. There was no significant interaction among nano silver, organic fertilizers and salicylic acid on all studied traits of sunflower.
