Previous issue date: 2010 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (Capes) / Este trabalho teve como objetivo comparar em tr?s cultivos a produtividade, componentes de rendimento, atributos qu?micos do solo e a nutri??o do feijoeiro em quatro sistemas de preparo do solo de um Neossolo Quartzar?nico. O primeiro cultivo do feijoeiro foi realizado de abril a junho de 2006, o segundo, de novembro de 2006 a janeiro de 2007, e o terceiro de dezembro de 2008 a fevereiro de 2009. O delineamento experimental utilizado foi o de blocos casualizados no esquema de experimento em faixas, com cinco repeti??es. Os tratamentos foram os seguintes preparos do solo: arado de disco, arado de aiveca, grade pesada e plantio direto com o uso de dessecante na vegeta??o. Os sistemas de preparo influenciaram nos atributos qu?micos do solo, na produtividade e nutri??o do feijoeiro nas condi??es de Campo Limpo na Serra do Espinha?o Meridional. O plantio direto e grade pesada s?o os sistemas de preparo do solo mais adequados para a produ??o do feijoeiro, quando cultivado sob um Neossolo Quartzar?nico. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT This study aimed to compare three crop yields, yield components, soil chemical properties and nutrition of common bean in four tillage systems on soil conditions in Quartzarenic Neossol. The first crop of the common bean was in April-June, 2006, the second was from November, 2006 to January, 2007 and the third was from December, 2008 to February, 2009. The experimental design was randomized blocks of the scheme in split plot, with five replicates. The treatments were the following soil tillage: disk plow, moldboard plow, heavy offset disk harrow and no-tillage with the use of desiccant in vegetation. The tillage systems influenced the chemical properties of soil, yield and nutrition of bean plants under field conditions in the Campo Limpo in Serra of Espinha?o Meridional. No-till and heavy offset disk harrow are the most suitable soil tillage for the bean productivity when the growth is in a sandy soil.
