Effect of Inoculation and Growth Regulator on Soybean Yield and Photosynthetic Pigment Content
Year: 2006
Type: article
Abstract: Th e main objective of this study was to evaluate the infl uence of soybean inoculation with diff erent Bradyrhizobium japonicum strains and the application of Bioalgeen-S90, as a growth regulator, on photosynthetic pigment content and soybean yield. Regarding the main objective, both greenhouse experiment and fi eld trials were conducted. Th e positive eff ect of interaction between Bioalgeen-S90 and seed inoculation with B. japonicum strain D344 on photosynthetic pigment content was determined in greenhouse experiment. Th e results from fi eld trials showed a signifi cant infl uence of Bioalgeen-S90 on chlorophyll b and a+b content and soybean yield. Regardless of the B. japonicum strain used, inoculation had a signifi cantly positive eff ect on chlorophyll a, b and a+b content. Compared to the non-inoculated control variants, inoculation with both B. japonicum strains, showed the statistically signifi cant eff ect on soybean yield. Th e simultaneous application of Bioalgeen-S90 and B. japonicum strains caused the highest yield increase.
