Book Description
Soybeans (Glycine max (L.) Merrill) has been cultivated in Asia since time immemorial. However in the United States this culture only became important in the twentieth century. It is now one of the most importat crops in North America. The production of soybeans in the South Central and Southeastern States has increased. This shift in production from the North Central States has accentuated the seedborn disease problems of this crop. Fungicide seed treatment can help to control seedborn diseases and improve germination. A good nodulation is of maximum importance for soybean yield and it can be obtained only in presence of an effective strain of Rhizobium japonicum. Funcicidal effect upon the rhizobia is not clearly understood and consequently seed treatment is not generally a recommended practice for soybeans in Georgia...

Book Description
"Soybean [Glycine max (L.) Merr.] is a tropical to subtropical legume that requires root zone temperatures (RZTs) in the 25 to 30°C range for optimal symbiotic activity. The inability of soybean to adapt to cool soil conditions limits its development and yield in short season areas. In particular, nodulation and nitrogen fixation by this crop species is sensitive to cool RZTs. The isoflavone genistein, which is the most effective plant-to-bacterium signal in the soybean nitrogen fixation symbiosis, has been used to pretreat Bradyrhizobium japonicum inocula. This resulted in increased soybean nodulation and nitrogen fixation in several studies, indicating that genistein preincubated inocula could overcome low RZT inhibition of plant growth and yield. The effectiveness of isoflavones was found to vary among soybean cultivars. Some legume cultivars apparently supply limiting amounts of the flavonoids. The objective of this thesis was to determine how soybean cultivars of different maturity groups would respond to genistein incubation of B. japonicum prior to inoculation. Two field experiments were conducted in 1997 and 1998 involving eleven soybean cultivars of three maturity groups organized in a randomized complete block design. Cells of B. japonicum, treated with genistein or not, were applied onto seeds in the furrow at the time of planting. The results of this study indicated that genistein application increased nodule number and nodule dry matter per plant, increased plant nitrogen content, grain protein and grain yield of all cultivars. There was no interaction between maturity group and genistein application, and there was no correlation between maturity groups and increase in nodulation, total biomass, nitrogen content and yield due to genistein treatment. Thus, responses of soybean cultivars of different maturity groups to genistein treatment are not related to maturity and/or yield potential." --
