Soils with improved fertility indicate opportunities for more rational use of fertilizers. The objective of this study was to evaluate the management of potassium fertilization in the succession of soybean-corn in soil with improved fertility, in the southwestern region of the state, Goiás. The experiment was set in 5×3 factorial scheme, arranged in randomized blocks with four repetitions. The treatments consisted of the combination of potassium doses (0, 40, 80, 120 and 160 kg ha-1 of K2O) and seasons of application (100% of the dose in pre-planting, 100% of the dose in coverage and in installments with 50% of the dose in pre-planting + 50% in coverage). The best performance of soybean, considering grain yield, was obtained with the parceled application...

Honey Bee Health in Apiaries in the Vale do Paraíba, São Paulo State, Southeastern Brazil. Repositório Alice
SANTOS, L. G.; ALVES, M. L. T. M. F.; MESSAGE, D.; PINTO, F. A.; SILVA, M. V. G. B.; TEIXEIRA, E. W..
Bee health is a growing global concern due to phenomena with as yet undefined causes, such as the sudden population decline of colonies that has been observed in apiaries in many countries, recently including Brazil. The main objective of this study was to assess the presence and/or prevalence of pathogens that afflict Africanized Apis mellifera bees in the Vale do Paraíba region of São Paulo state, Brazil. Three sampling periods were established: period 1 ? August and September 2009 (winter/early spring); period 2 ? December 2009 and January 2010 (summer); and period 3 ? April and May 2010 (autumn). The results demonstrate that although mites and microsporidia are widespread in the region?s colonies, the Africanized bees are apparently tolerant to...
