摘要

The avocado (Persea americana) has become a valuable crop in Ethiopia due to its nutritional value and ability to adapt to different climates. Although indigenous to Central and South America, avocados have flourished in Ethiopia’s varied agricultural landscape, particularly in regions such as Oromia and the Southern Nations, Nationalities, and Peoples’ Region (SNNPR). However, a common challenge for avocado growers is fruit drop, where mature and immature avocados fall from the tree before they can be harvested. This phenomenon can be triggered by several factors, including natural factors (environmental conditions), nutritional factors, physiological causes, pathological agents (tree health), and issues with fruit development. Young avocados are especially prone to dropping during their early stages of growth fruitlets. Stressors such as drought, excessive rainfall, nutrient deficiencies, and pest infestations can lead to increased fruit drop as the tree prioritizes its resources. Additionally, avocados exhibit a characteristic known as alternate bearing, where a tree produces a large crop one year and a smaller one the next. This cycle often results in heightened fruit drop during the off year. Understanding and managing these factors are crucial for improving avocado yields in Ethiopia.
