Atributos físicos e desempenho agronômico da cultura da soja em um Latossolo Vermelho distroférrico submetido a dois sistemas de manejos

Abstract: RESUMOOs sistemas de manejo agindo com condicionadores do solo podem alterar a qualidade física do solo e restringir ou maximizar a produção agrícola. Objetivou-se com este estudo avaliar os atributos físicos e o desempenho agronômico da cultura da soja em um Latossolo Vermelho distroférrico submetido a dois sistemas de manejos em Dourados-MS. O delineamento experimental foi em blocos casualizados, em esquema de parcelas subsubdivididas, sendo dois sistemas manejo do solo nas (parcelas) com 0 e 2000 kg ha -1 d… Show more

“…The absence of supplementary irrigation had similar effect to irrigation depth of 100% ETc on FPH, which did not vary between cultivars. With irrigation depths of 50 and 75% ETc, the highest values were found in the cultivars M7739IPRO and NA909RR. Comparing the data of rainfed treatments with those obtained by Souza et al (2010), who studied the same variables and in the same type of soil, but in a region with lower rainfall regime, it is possible to observe some differences between these characteristics. The values of plant height and number of pods per plant were similar.…”

“…These amendments lead to increased plant height (CUSTÓDIO et al, 2005;SOUZA et al, 2010), increased production of dry matter (CUSTÓDIO et al, 2005;CRUSCIOL, 2008), higher nutrient absorption efficiency (CAIRES et al, 2006;CUSTÓDIO et al, 2005;RAMPIM et al, 2011), and consequently, better grain quality (CAIRES et al, 2006). The results of previous studies are contradictory with regard to grain yield (CAIRES et al, 2006;MASCHIETTO, 2009;NEIS et al, 2010;RAMPIM et al, 2011;SORATTO et al, 2010).…”

“…Alguns estudos demonstram os efeitos negativos do preparo do solo nos FMAs, sugerindo que isso possa promover a redução no rendimento da cultura posterior ao revolvimento do solo (COLOZZI-FILHO et al, 1999, KABIR, 2005, SOUZA et al, 2010. O preparo do solo é o mais direto e drástico estresse cultural que incide sobre a formação das micorrizas.…”
