| Abstract | ||
| The current study was conducted at a plastic house belong to College of Agriculture/ Al-Qadisiya university during the growing season 2012-2013 in order to study the effect of spray with seaweed extract at 0, 3, and 6 ml/L and amino acids at 0, 400, and 800 mg/L and their combination on some vegetative and root growth characters, yield fruits quality of sweet pepper Capsicum annuum L. cv. Flavio. Results showed that there were a significant increase in plant height, number of fruting branches, dry weight of shoot and root and chlorophyll leaf content at 6 ml/L of seaweed or and 800 mg/Lof amino acids. Also, mean fruit number, plant yield, and total yield, vitamin C content, phenols, total soluble solids (T.S.S) and sugars were increased significantly at the highest concentrations of both seaweed extract and amino acids compared to control treatment. For the combination of the factors, it was showed that the combination of seaweed at 6 ml/L and amino acids at 800 mg/L gave the highest values of the parameters measured in compare to the control. | ||
