| Abstract | ||||
| This study was carried out through 2014 and 2015 in a private date palm orchard located in New Assuit City district, Assuit Governorate to study the effect of spraying with different concentrations of two seaweed extraction, (Eprosil-k at 4%) and (Oligo-x at 2 or 4%) either alone or with silicon nutrient at (0.5%), on yield and fruit quality of Zaghloul date palms. palms sprayed three times during grown seasons (first of April, May and June) with Seaweed extracts at 2 or 4% either alone or with silicon were very effective on improving yield and fruit quality (fruit weight, dimensions, total soluble solids and sugar contents) in comparison with control treatment. The promotion on these characters was observed when the concentrations of Oligo-x (Seaweed extract compound) were increased from 2 to 4%. The best results with regard to yield and fruit quality of Zaghloul date palms were obtained due to spray the palms three times with a mixture of seaweed extract (Oligo-x at 4%) and silicon nutrient at 0.5%. | ||||
