The performance of the soybean (Glycine max) inoculated with Bradyrhizobium is influenced by cropping history. However, re-inoculation with elite strains of Bradyrhizobium generally provides increases in soybean grain yield. The Amazonian savanna has an agricultural frontier area where soybeans have recently been introduced. In this study, we evaluated soybean nodulation, N accumulation, N2 fixation, and grain yield responses to inoculation with the commercial Bradyrhizobium strains SEMIA 587 and SEMIA 5019 of B. elkanii, SEMIA 5079 of B. japonicum, and SEMIA 5080 of B. diazoefficiens.

The Amazonian savanna has an agricultural frontier area where soybeans have recently been introduced.

Four field experiments were performed in areas with or without previous cropping with inoculated soybean that contained preexisting bradyrhizobia populations of???103 or?<?102 cells g?1 soil, respectively. Inoculation of soybean in first-year cropping areas resulted in increases in several parameters compared to those in non-inoculated soybean; as expected, these effects were less pronounced when areas had been previously cropped with soybean. Despite no statistical differences, re-inoculation provided average increases in grain yield of 12 to 18% compared to that in the non-inoculated control. A dose of 200 kg ha?1 of N-fertilizer impaired the nodulation and did not increase grain yields when compared with the inoculation. Estimates obtained with the 15 N natural abundance technique confirmed the high contribution of N2 fixation in inoculated plants, ranging from 84 to 90%. Although soybean cropping increases the soil bradyrhizobia population size, annual inoculation is important to guarantee host infection by efficient strains of soybean Bradyrhizobium and their persistence in savanna soils.

Abstract: The aim of this study was to identify whether more and less adapted Angus and Simmental cattle differed in physiological responses and expression of the heat shock factor 1 (HSF1) and the heat shock 70 kDa protein 6 (HSPA6), when subjected to heat stress. Thirty bulls (n=15 ANG; n=15 SIM), extremes ?more adapted" and "less adapted" within each breed were selected to the heat tolerance test. They were selected according to an index based on the average of the respiratory rate obtained on two hot summer days from one hundred bulls. Before the heat tolerance test day, animals were taken to a paddock with water, grass and shade until 7 a.m. of the following day for morning measurements. They were kept in the barn without access to water and shade until 1 p.m. for the afternoon measurements. Respiratory rate in the morning (MRR) and afternoon (ARR), hair coat surface temperature in the morning (MST) and afternoon (AST), rectal temperature in the morning (MRT) and afternoon (ART) were measured and blood samples were collected for expression analysis of the HSF1 and HSPA6 genes. The MIXED procedure of SAS was used for all statistical analysis. The more adapted Simmental group had lesser values of MRR (P=0.023) and MRT (P=0.095), but there was no difference within Angus breed. The ARR was greater (P=0.004) in less adapted animals for both breeds. The ART was lower in the Simmental breed (P < 0.001). Less adapted had greater levels of mRNA of HSF1 (P=0.06) and HSPA6 (P=0.09). In conclusion, respiratory rate, rectal temperature and expression of the HSF1 and HSPA6 genes can be indicators of thermotolerance in taurine cattle. Both breeds show physiologically similar responses under heat stress conditions.
