Resumo: The effects of different values of base saturation (BS) (25%, 50%, 120%, and 150%) and different corrected layers (0-5, 0-10, 0-15, and 0-20 cm deep) of a soil on the dry matter production of Guinea grass (Panicum maximum Jacq.) were studied. The substrate utilized was an acid, allic and dystrophic dark red latosol. The experiment was carried out in a greenhouse and the plants were grown under controlled conditions. A randomized block factorial design with five corrected layers, four BS values and a control with four replicates was used. The experiment consisted of 84 experimental units. After fifty-six days of culture, the plants were harvested. The shoot and the roots collected from the different corrected layers were washed with deionized water and oven-dried at 65oC so as to determine the dry matter. The soil samples collected from the different corrected layers were submitted to chemical analyses. The determined values of BS corresponded to the theoretical values of BS up to 50%. Above this level, the determined BS values were lower than the theoretical ones. The root and the shoot dry matter production of Panicum maximum were reduced when the theoretical values of BS were higher than 120% and 50% respectively

Estudaram-se os efeitos de diferentes valores de saturação por bases e de camadas de correção da acidez do solo sobre a produção de matéria seca do capim-tanzânia (Panicum maximum Jacq). Foi utilizado um esquema fatorial 5 x 4 + 1 (testemunha) com cinco camadas de correção (superficial-S, 0-5, 0-10, 0-15 e 0-20cm) e quatro níveis de saturação por bases (V% de 25%, 50%, 120% e 150%) com 4 repetições, tendo sido estabelecido um delineamento inteiramente casualizado, totalizando 84 unidades experimentais. Cinqüenta e seis dias após a semeadura, foi realizado o corte da parte aérea das plantas e separação solo/raízes. O material vegetal foi lavado e seco em estufa de circulação de ar a 65ºC para a determinação da matéria seca. As amostras de solo coletadas nas camadas de 0-5, 5-10, 10-15 e 15-20cm foram submetidas às análises químicas para a determinação do V% real. Os valores obtidos de V% real corresponderam aos valores de V% teórico até o nível de 50%. Acima desse nível, os valores de V% real ficaram abaixo dos valores teóricos. Em geral, a produção de matéria seca das raízes e a produção de matéria seca da parte aérea foram reduzidas à medida que o V% assumiu valores teóricos acima de 120% e 50%, respectivamente, e à medida que a camada de correção foi crescenteUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/287010.4025/actasciagron.v22i0.2870Acta Scientiarum.
