open soybean area, the yield increased 6.3% over the caged area. The increase in yield when<br />
honeybees were introduced in the area, compared to caged soybeans, was attributed to 10%<br />
increase in the number of pods, 3% increase in the number of pods with two seeds <strong>and</strong> 5% in<br />
the number of pods with three seeds.<br />
In conclusion, there are conflicting results in the revised literature. While some authors<br />
found 10-50% increase in soybean yield, when insect pollination conditions are adequate,<br />
other refer that cross-pollination is in the range of 0.5-2% <strong>and</strong> soybean flowers are fertilized<br />
when open. A net of studies involving different years, genetic material, latitude <strong>and</strong> environmental<br />
condition should be set up to clarify the controversy.<br />
