Número mais provável e eficiência de Rhizobium autóctone para soja perene e siratro em quatro Grandes Grupos de solos do estado de São Paulo

Abstract: Com o objetivo de determinar numericamente a população de Rhizobiumque se associa com soja perene e siratro, em quatro grandes grupos de solos do Estado de São Paulo, e avaliar a eficiência dessa população em solo sob cultivo de gramíneas (pastagens) e sob cultivo de soja perene, foram conduzidos os ensaios aqui relatados. Para a determinação numérica de Rhizobiumfoi utilizada a técnica de "número mais provável". Para a avaliação da eficiência as leguminosas foram cultivadas em vasos de Leonard com solução nut… Show more

“…Cultivated areas containing Neonotonia wightii (Lopes et al, 1972), peanut (Giardini et al, 1985;Lombardi et al, 1992) or green manure legumes (Chada & De Polli, 1988;Rodrigues et al, 1994, Zilli et al, 2004 were capable of maintaining rhizobial communities that were highly infective for their host plants and well adapted to soil conditions. Several studies indicated that the rhizobial communities can be affected by the properties of the soil and by the host plants (Palmer & Young, 2000, Zhang et al, 2001Laguerre et al, 2003), as well as by soil tillage (Cattelan & Vidor, 1990;Castro et al, 1993, Carvalho et al, 2004, and crop history (Venkatesvarlu et al, 1997).…”
