Impact of the foraging activity of Apis mellifera adansonii Latreille (Hymenoptera: Apidae) and Bradyrhizobium fertilizer on pollination and yield components of Glycine max L. (Fabaceae) in the field

摘要: To determine the impact of Apis mellifera adansonii and Bradyrhizobium on pod seed yields Glycine max , field trials were carried out during 2012 2013 cropping seasons. Hence, 120 to 25658 flowers labeled each year divided into five treatments, differentiated according whether plots inoculated with or not, plants protected from insects activities not last treatment isolated then opened only A. m. . The effects nodulation, plant biomass yield, as well foraging behavior flowers, number seeds per normal seeds' rate evaluated. Results indicate that significantly increased (P<0.001), root nodules (P<0.0001), in plots. foraged G. 09.00 a.m. 16.00 p.m. throughout whole blooming period. This insect intensely harvested nectar. By comparing unprotected those 35.85% increase fructification index, 73.09% due this bee recorded. synergistic activity by 32.16% percentage 32.87%. Our results reveal inoculation soybean at sowing installation hives close could be recommended for a sustainable pods yield improvement crop.
