Efeitos da aplicação de manganês no crescimento, na nutrição e na produção de matéria seca de plantas de Brachiaria brizantha (cv. MG4) em condições de casa de vegetação

Abstract: A adubação com micronutrientes, como o manganês em gramíneas forrageiras tropicais, contribui para o atendimento das exigências nutricionais tanto das plantas quanto dos animais. Objetivou-se, neste trabalho, estudar os efeitos da aplicação de manganês no crescimento, na nutrição e na produção de matéria seca de plantas de Brachiaria brizantha, em condições de casa de vegetação. Para isto, realizou-se um experimento em casa de vegetação da FCAV/UNESP, Campus de Jaboticabal, com Brachiaria brizantha (cv. MG4), … Show more

“…In saline soils, an increase in the concentration of Na and a reduction in exchangeable Ca promotes ionic imbalance [43]. In the case of Mg, the high recovery is due to the activity of lactic acid bacteria that accumulate Mn [29,44]. For micro-nutrients, Zn recovery was related to the plug process, which is the accumulation of buffers containing Zn, hindering the rise of crude sap [37]; therefore, the movement of minerals to the bottom of the silo may have increased.…”

“…Although signal grass is sensitive to salinity, in contrast to other perennial grass species (Deifel et al., 2006), it has adaptive characteristics that enable it to survive in metal contaminated soils (Ferreira et al., 2021). The grass has medium tolerance to Mn allowing high levels in the shoot without causing visual symptoms of toxicity (Puga et al., 2012). In addition, it has tolerance of lead (Pb) (Kopittke et al., 2007), and can accumulate cadmium (Cd) and copper (Cu) in plant tissue without causing toxicity (Rabêlo et al., 2020; Silva et al., 2018).…”
