Morphological Response of Stevia Rebaudiana Bertoni to Organic Fertilizer and Proline

Abstract

Abstract. A field experiment was carried out in the wooden canopy - Department of Horticulture and Gardening Engineering - College of Agriculture - University of Anbar to testing the response of Stevia rebaudiana bertoni to spraying Organic fertilizer and Proline, three levels of Organic fertilizer (0mg, 50mg and 100mg) used, as well as three levels of Proline used (0mg, 100mg and 200mg). The results showed that the treatments sprayed with the Organic fertilizer (100mg) were significantly superior with the highest ratios of plant height, number of leaves per plant and leaf thickness, recorded (55.20cm) (729 leaf) (07370mm), respectively Whereas, the best ratios of the above characteristics were recorded when spraying with Proline, (87.04cm) (737 leaf) (07620mm) respectively. The highest rate of plant height, the number of leaves per plant, and the thickness of the leaf were recorded when the interaction between the experiment factors, where the highest rate was recorded at the interaction (100 mg Organic fertilizer and 200 mg Proline) the highest ratios were recorded (97.50cm) (789 leaf) (07740mm), respectively.
