Abstract

We conducted the experiment in the town of Al-Bu-dhiyab, west of Ramadi during 2024's spring season on 5-year-old Ibrahimi apple trees, to study the effects of injecting micro-Nano elements and adding seaweed extract on vegetative growth, chemical properties, and yield. The experiment included three levels of injection: (0 - injection with distilled water only, B10+Fe20, and B20+(Fe40 mg L-1)) and the addition of seaweed extract at four concentrations: (0 - injection using just pure water from distillation, 3-, 6-, as well as 9- ml. L-1). Treatments were applied in three batches on March 16, with a 20-day interval between each treatment. The following characteristics were studied: The content of chlorophyll a and b in leaves, Content of leaves in boron and iron, Percentage of remaining fruits, Fruit fall percentage, Fruit firmness, and The percentage of total soluble solids in the fruits T.S.S.
The findings indicated that the injectable therapy (B20+ (Fe40 mg L-1) resulted in a substantial enhancement of most examined features. Likewise, the incorporation of seaweed extract (9 ml L-1) resulted in an extensive improvement for examined attributes. The interaction between the study components revealed that the injectable therapy at the concentration of B20+(Fe40) and the addition of seaweed extracted with a level for 9 ml L-1 performed in most evaluated features.
