Response of Sunflower (Helianthus annuus L.) to Spraying of Nano Silver, Organic Fertilizer (Algastar) and Salicylic Acid and Their Impact on Seeds Content of Fatty Acids and Vicine‬?

Abstract

This experiment is carried out on Sunflower (Helianthus annuus L.), Spanish class (Viki) in one of the fields for the period from 05/03/2013 until 18/06/2013, where the shoots are sprayed after period of 65 days of its cultivation with 25 and 50 ml/l of nanosilver, 0.75 and 1.5 g/l of organic fertilizer (Algastar) and with the use of salicylic acid in two concentrations 60 and 120 mg/l in addition to the comparison treatment (spraying with distilled water only). The field experiment is laid as a factorial experiment which included three factors in RBCD design with three replications (3×3×3×3) that included three factors, the averages of transaction are compared by using LSD (least significant difference at 0.05%). Results of the experiment have shown that spray shoots with 50 ml/l of nanosilver, 1.5 g/l of organic fertilizer (Algastar) and 120 mg/l of salicylic acid gave the highest positive effects of unsaturated fatty acids while the same high concentration of factors reduced the content of the most of the saturated fatty acids and vicine.The three way interaction has affection on field experiment in some studied traits positively while it has no significant effect on seeds content of vicine and fatty acids (Palmitic, Stearic, Archaic, Myristic, Linoleic and Oleic).
