Resposta do milho a doses de fósforo

Abstract: RESUMOConduziu-se um experimento em casadevegetação, do Centro de Ciências Agrárias da Universidade Federal de Alagoas, Rio Largo, AL, com o objetivo de avaliar o efeito de diferentes doses de P recomendadas pela capacidade máxima de adsorção de fósforo -CMAP (%), sobre os teores de P e matéria seca da cultura do milho, em solos de Alagoas. Os solos foram classificados como Latossolo Amarelo coeso, Argissolo Acinzentado, Neossolo Flúvico, Neossolo Quartzarênico, Luvissolo Crômico órtico e Luvissolo Crômico pál… Show more

“…Since P was the limiting factor in the soil, increasing the application of this nutrient strongly affected plant development, resulting in increments in all evaluated variables (Figure 1). Bastos et al (2010) studied six soils with P doses ranging from 135 to 463 mg kg -1 and did not find any effects on plant development for the same soil; however, the increase in P doses resulted in a higher content of the nutrient in the shoot. The presence of AMF spores or mycorrhizal colonization was not observed in uninoculated treatments, confirming the asepsis of the experiment.…”

“…Existe, pois, uma relação direta entre produtividade, acúmulo de matéria seca e de nutrientes (Possamai, 2003;Aquino et al, 2011). Solos mais argilosos (mais tamponados) podem condicionar menor conteúdo de nutrientes na planta (Bastos et al, 2010).…”

“…De maneira que, em trabalho conduzido por Bastos et al (2010) também demonstraram a possibilidade de utilizar o P-rem correlacionando com a CMAP para recomendar adubação para a cultura de milho, pois em Neossolo Flúvico a adubação fosfatada com dose correspondente a 30% da CMAP proporcionou incremento do teor foliar de P. Desta forma, a ausência de interferência do gesso no P-rem permite utilizar a recomendação de adubação fosfatada na cultura de milho baseada no P-rem, conforme Bastos et al (2010).…”
