Effect of Prosol and Brassinolide on growth and yield of Fig (Ficus carica L.)

Abstract

Foliar fertilizer nutrient Prosol at levels of 0, 0.5, 1.25 and 2 g.l-1 and growth regulator 24-epibrassinolide (BL) at levels 0,1, 3 and 5 mg.l-1, respectively, were applied on the fig trees Ficus carica L. cv. “Aswad Diyala” planted in an orchard in Diwaniyah city during the 2013 and 2014 seasons. 2g.l-1 Prosol and BL 5mg.l-1 treatments gave the best results in leaf area (4.96, 5.59 m2.tree-1, respectively), yield (17.88, 18.78 kg.tree-1, respectively), potassium levels (305.78, 306.44 mg.100g-1, respectively) and anthocyanin (546.2, 551.8 mg.100g-1, respectively) for two seasons. Significant interaction peaked at the fourth level in the leaf area (5.48, 6.33 m2.tree-1, respectively) and yield (17.88, 18.78 Kg.tree-1, respectively) for two seasons. Potassium level significantly increased only in the 2014 season (306.44 mg.100 g-1). Spray fig trees cv. “Aswad Diyala” – in the city of Diwaniya- with Prosol at level 2 g.l-1 and Brassinolide at level of 5 mg.l-1 gave the best results.
