an experiment was conducted at assossa agricultural research center (aarc) station during 2008 cropping season in order to study the effects of co-inoculation of bradyrhizobium japonicum (tal-378 and tal-379) and phosphate-solubilizing bacteria (psb) (pseudomonas spp.), and conventional farmers’ fertilizer level (combined and individual application of 46n kg ha-1 and 46 p2o5 kg ha-1) on nodulat...

the essential oil extracted from the epicarp of citrus sinensis exhibited absolute fungitoxicity against soybean’s fungus as alternaria alternate, aspergillus niger, cercospora kikuchii, chaetomium spp., cladosporium cladosporioides, curvularia lunata, fusarium roseum, macrophomina phaseolina, penicillium italicum, phomopsisspp. rhizoctonia solani, and sclerotium rolfsii. it is very difficult t...

In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...

Loss of seed viability is a serious hurdle in production and ambient storage soybean. Understanding the factors affecting viability, identification soybean genotype(s) with higher critical for production. In this study, seeds 125 genotypes three different species [Glycine tomentella Hayata, Glycine max subsp. soja (Siebold & Zucc.) H. Ohashi, max(L.) Merr.] 25 RILs (Glycine × max) were tested g...
