The Use of Honeybee Hives May Boost Yields of Some Crops in Nepal

Figure 1

Production of bittergourd, buckwheat, and mustard crops in Nepal. Control = excluding all flower visitors; honeybee hives = adding Apis mellifera beehives; ans open access to insect = flowers freely accessible to any foraging insect. Note. Different letters over boxes indicate a significant difference at a low α-level of 0.05; dashed lines in plots show the average production for every crop: bitter gourd (20.12 tons/ha), buckwheat (6.60 quintal/ha), and mustard (6.81 quintal/ha); and a ton is a tenth of quintal unit.
