Comportamento de genótipos de feijoeiro em latossolo vermelho distroférrico típico com diferentes graus de compactação

Abstract: Visando a avaliar o comportamento de quatro genótipos de feijoeiro em diferentes condições de compactação do solo, foram conduzidos dois experimentos em campo nas safras das águas 98/99 e seca/99, em um Latossolo Vermelho distroférrico típico da área experimental do Departamento de Agricultura da UFLA. O delineamento experimental utilizado foi em blocos casualizados com quatro repetições e esquema fatorial 6 x 4 envolvendo seis níveis de densidade do solo (1,08 ; 1,24 ; 1,36 ; 1,39 ; 1,41 e 1,50 g.cm-3 ) e qua… Show more

“…The results indicate that the rhizobia and cowpea symbiosis may have provided nitrogen in similar amounts as compared to nitrogen fertilization, benefiting the crop development. Alves et al (2003) conducted a study using three soil types (Dystrophic Red-Yellow Latosol of medium texture, Dystrophic Red-Yellow Latosol, clayey, and Typical Distroferric Red Latosol) and five compaction levels (50, 62.5, 75, 87.5 and 100% of maximum density) and found that the compaction did not alter the nitrogen uptake and the nitrogen content in bean plants, the best values being found at the density of 2.12 Mg m -3 in the Dystrophic Red-Yellow Latosol of medium texture. Mandal et al (1990), using three compaction levels (moderate -1.79 kg dm that the loss of nitrate through leaching was three to four times lower in the highly compacted soil, as compared to the uncompacted soil.…”
