Plant growth analysis describing the soybean plants response on dryland field to seed co-inoculation
ABSTRACT: Plant growth analysis can be used for soybean plants evaluation to identify morphologic changes caused by soil microbes after seed inoculation. The objective was to measure changes of inoculated soybean plants grown under regular field Brazilian production conditions. The experiment was carried out to compare 5 inoculation treatments: T1 (Bradyrhizobium japonicum and B. diazoefficiens), T2 (T1 and Azospirillum brasilense), T3 (T1 and Trichoderma asperellum), T4 (T1 and T. virens, and Bacillus amyloliquefaciens) and T5 (T1 and Penicillum bilaiae). Leaf area, shoot and root dry matter were measured at vegetative and reproductive growth stages. Results of this study validate the contribution of plant growth analysis of soybeans plants for identifying their responses promoted by the combined inoculation of their seeds with selected microbes. Also, the microbial effects on plant growth vary not only between microbes but also between parts of the plants and through the plant development stages. The introduction of different microbes in soybean rhizosphere combined with Bradyrhizobium sp. strains can contribute to increase crop dry matter productivity during its growing cycle.
