The Contribution of Managed Honey Bees to Crop Pollination, Food Security, and Economic Stability: Case of Ethiopia

Table 1: The mean and standard error (SE) of marketable fruit yield per tree, per hectare of apple trees, and seed yield of Niger seed /hectare under different treatment.

Treatment	Mean Marketable Apple Fruit Yield kg/tree + SE (kg)	Average Apple Fruit Yield kg/ha	Seed Yield of Niger Seed /ha(kg)
T1 = Caged with honey bees	3.2 + 0.4^a	3,560	1669^a
T2 = Open pollination	2.2 + 0.37^ab	2,440	1324^ac
T3= Caged without insect pollinators	1.8 + 0.22^b	2,000	960^c
