Resumo: | This paper evaluates the effects of the introduction of no tillage systems (SPD) in rainfed maize grain production, by smallholders, under Cerrado conditions, in the region of Unaí, Minas Gerais State, Brazil. The main constraints faced by farmers to produce are related to soil fertility management, difficulties in assessing tractors for preparing their land, and high levels of weed infestation. SPD was tested jointly with farmers trying to decrease these problems impacts. It showed promising results to stabilize, technically and economically, maize production. SPD solved completely the tractors dependency and contributed to decrease labour requirements for weed control. The production levels attained led to a better valorisation of the most scarce production factors, such as family labour and land. It was also evidenced the need to conduct more studies on the use of cover crops in those production systems. Key-words: Family farming; conservation agriculture; no-tillage. |

Este artigo analisa o efeito da introdução do uso do sistema plantio direto (SPD) no cultivo de milho grão sequeiro, em condições de Cerrado, por agricultores familiares de Unaí, MG. As principais limitações para a condução das lavouras desses agricultores relacionam-se ao manejo da fertilidade, precariedade de acesso à mecanização para preparo de solo e alta infestação de plantas daninhas. O SPD foi testado junto a esses agricultores, buscando-se limitar os efeitos desses problemas. Ele mostrou-se promissor para viabilizar, técnica e economicamente, a produção de milho dos assentados. O plantio direto eliminou a dependência de maquinário para preparo de solo e reduziu a carga de trabalho para controle de plantas daninhas. As produtividades alcançadas possibilitaram a valorização de fatores escassos, tais como a terra e, sobretudo, a mão-de-obra familiar. Evidenciou-se, também, a necessidade de se conduzir mais estudos sobre o uso de plantas de cobertura nesses sistemas de produção.
