Title A name given to the resource Desenvolvimento e nodulação natural de leguminosas arbóreas em solos de Pernambuco Development and natural nodulation of legume trees in soils from Pernambuco, Brazil Creator An entity primarily responsible for making the resource Newton Pereira Stamford, Egídio Bezerra Neto, Luiz Augusto Gomes de Souza, Carolina Etienne de Rosália Silva Santos Description An account of the resource O objetivo deste trabalho foi avaliar o desenvolvimento e nodulação natural de leucena (Leucaena leucocephala), palheteira (Clitoria fairchildiana) e sabiá (Mimosa caesalpiniifolia), em solos com diferentes formas de uso da terra, da Zona da Mata de Pernambuco. Foram utilizados quatro solos de mata, seis solos de áreas agrícolas e dois de áreas degradadas. Os solos foram classificados, analisados quimicamente e distribuídos, 3 kg de solo por vaso, com duas plantas por vaso. A colheita das mudas foi feita aos 76, 70 e 62 dias, para leucena, palheteira e sabiá, respectivamente. O delineamento experimental foi inteiramente casualizado, com 12 tratamentos e 3 repetições. Foram constatadas baixas freqüências de populações nativas de rizóbios para leucena, 22% de plantas noduladas, em comparação à palheteira e sabiá, 100 e 86%, respectivamente. A palheteira apresentou nodulação natural abundante e eficiência na fixação de N2, o que demonstra compatibilidade com as populações nativas de rizóbios. O crescimento, o desenvolvimento, a nodulação e o acúmulo de nitrogênio das três espécies foram favorecidos no solo de área agrícola com cobertura de Calopogonium mucunoides. A palheteira apresentou o maior potencial para fixação de N2 e eficiência da nodulação com populações nativas de rizóbios, seguida por sabiá e leucena.The objective of this work was to evaluate the development and natural nodulation of Leucaena leucocephala, Clitoria fairchildiana and Mimosa caesalpiniifolia, in soils with different type of land use, in Zona da Mata of Pernambuco, Brazil. Soils of four forest areas, six agriculture areas and two degraded areas were used. Soils were classified, analyzed chemically and distributed in pots 3 kg soil per pot, two plants per pot. Plant evaluations were carried out at 76, 70 and 62 days, for L. leucocephala, C. fairchildiana and M. caesalpiniifolia, respectively. The experimental design was completely randomized, with 12 treatments and 3 repetitions. Low frequencies of native populations of rhizobia were verified for L. leucocephala, with 22% of plants nodulated, compared to C. fairchildiana and M. caesalpiniifolia, with 100% and 86%, respectively. M. caesalpiniifolia presented abundant natural nodulation and efficiency in the fixation of N2, demonstrating compatibility with native populations of rhizobia. Growth, development, nodulation as well as accumulation of nitrogen of the three species, were favored with soil under agricultural areas with covering of Calopogonium mucunoides. C. fairchildiana presented greater potential for fixation of N2 and efficiency of the nodulation with native populations of rhizobia followed by M. caesalpiniifolia and L. leucocephala.
