ABSTRACT - The objective of this work was to investigate changes in soil chemical characteristics, phosphorous concentrations in maize leaves, and the agronomic efficiency (AE) of magnesium thermophosphates produced from rocks of the Maicuru complex in the Brazilian Amazon Basin, in comparison with triple superphosphate (TSP). The thermophosphates consisted of a mixture of raw material from apatite, dunite, and quartz sandstone from Maicuru, aiming to adjust the contents of P, Mg, and Si. The mixture was melted, ground, and subjected to the analysis of solubility, chemical characteristics, and granulometry. The experiment consisted of two rates of dolomitic lime (0 and 2.4 Mg ha-¹), three rates of P (20, 60, and 100 mg kg-¹ soil), and four sources of P (TSP and three Mg thermophosphates), as well as of two control treatments, with and without lime. Three replicates were carried out per treatment in pots containing plants of the BR 5107 maize hybrid. Phosphorous concentration was determined in maize leaves at 45 days after sowing. The Mg thermophosphates showed a high AE and a higher neutralizing effect with the application of lime, which improved soil chemical characteristics and AE. The thermophosphates obtained from rocks of the Maicuru complex can be an alternative P fertilizer in maize production. RESUMO- O objetivo deste trabalho foi investigar mudanças em atributos químicos do solo, concentrações de fósforo em folhas de milho e eficiência agronômica (EA) de termofosfatos magnesianos produzidos com rochas do complexo de Maicuru, na bacia da Amazônia brasileira, em comparação ao superfosfato triplo (SFT). Os termofosfatos consistiram de mistura de matéria-prima de apatita, dunita e arenito quartzoso de Maicuru, para ajuste dos conteúdos de P, Mg e Si. A mistura foi fundida, moída e submetida à análise de solubilidade, características químicas e granulometria. O experimento consistiu em dois níveis de calcário dolomítico (0 e 2,4 Mg ha-¹), três níveis de P (20, 60 e 100 mg kg-¹ de solo) e quatro fontes de P (TSP e três termofosfatos magnesianos), além de dois controles, com e sem calcário. Foram realizadas três repetições para cada tratamento, em vasos com plantas de milho do híbrido BR 5107. A concentração de P foi determinada nas folhas de milho aos 45 dias após a semeadura. Os termofosfatos magnesianos apresentaram alta EA e maior poder neutralizante com a aplicação de calcário, o que melhorou as características químicas do solo e a EA. Os termofosfatos obtidos de rochas do complexo Maicuru podem ser alternativa de fertilizante fosfatado na produção de milho.

Most studies selecting antagonistic microorganisms have focused on one pathosystem and then extended to others, but this approach was not a viable alternative for mango decay which is caused by a pool of pathogens in the tropics. In this study, 182 yeast isolates were isolated from ripe fruits of native wild plant species and other fruit crops from the Brazilian semi-arid region and selected against four prevalent agents of mango decay in tropical regions. The largest number of isolates was obtained from table and wine-grapes, followed by the native Spondias tuberosa. In dual culture assays, 8.8% of the yeast isolates showed growth inhibition halos of at least one of the pathogens. However, only six yeasts reduced the development of lesions in vivo to less than 50% to all the pathogens. Yeast/pathogens co-inoculation in healthy mango fruits in semi-commercial conditions showed that S. cerevisiae ESA45, Saccharomyces sp. ESA47 and Pichia kudriavzevii CMIAT171 had the larger spectrum of control efficiency, significantly reducing rot incidence and severity of all pathogens. The isolates also showed a variable tolerance to abiotic stress and biomass production. These results show the potential of these epiphytic yeasts as biocontrol agents of multiple pathogens infection in mango fruits. |
