Abstract

The aim of this study was to check the increase of seed production of soybean, cv IAC-14, owing lo the cross pollination performed by insects, mostly honey bees. The honey bee Apis mellifera was very numerous in the area owing to the large number of hives in nearby bee yards. At the flowering time (February, 1994) pollination cages (4mx3mx2m) were set up with the objective of obstructing the insect access. Other areas with the same dimension (4mx3m) remained freely visited by bees and other insects, and still other areas had their plants bagged with gauze. The experimental design used was the complete randomized one with three treatments (caged, visited and bagged plants). The mean of the number of pods per pit, the number of seeds per pod, the number of seeds per pit, the weight of pods per pit and the weight of seeds per pit were compared by the Tukey test (P<0.05). It was verified that the numbers of pods and seeds per pit were bigger (P<0.05) in the visited plants (199.65 and 397.54) than in the caged ones (125.90 and 218.05). On the other hand, the numbers of pods and seeds per pit in the caged plants were bigger than ones of the bagged plants (59.53 and 99.52). The number of seeds per pod in the visited plants was bigger (P<0.05)(1.91) than the ones of the caged plants(1.66). The weights of pods and seeds per pit were bigger (P<0.05) in the visited plants (66.20 and 45.90g) than in the bagged ones (28.92 and 19.36g).
