Abstract
Manihot esculenta Crantz is a native species of central Brazil present in all tropical and subtropical territories, has good adaptability, tolerance to drought and presents satisfactory yield in low fertility soils, promising crop in the family agriculture, contributing to the social and economic development of Brazil. In spite of this, traditionally, the culture is conducted with low financial investment, and in general, does not have the application of corrective and fertilizer in adequate doses. The objective of this work was evaluate the effect of two types of soil preparation; achievement or not of plaster; and four limestone rates on cassava yield (IAC 12). The experiment was carried out in a sub-divided plot with 24 replicates. Two types of soil preparation were evaluated: one with plow and grating and the other only with grating; plastering (0 and 650kg / ha); and four doses of limestone (0, 600, 1000, 1400 kg / ha). Harvesting was performed 10 months after planting and productivity per plant was determined. Variance analysis and ScottKnott's test were performed to compare means. It was found that there was no significant response to any of the treatments performed.

Summary
Júlio Cesar Reis Araújo, Alandionys Gonçalves de Lima, Juracy Mendes Moreira , Antonio Florentino de Lima Junior , Arinaldo Pereira da Silva , Lucas Roberto de Carvalho , Juliano Queiroz Santana Rosa6*. Tradicionalmente a cultura é conduzida com baixo investimento financeiro, geralmente, não havendo aplicação de corretivos e fertilizantes em doses adequadas. O objetivo deste trabalho foi avaliar o efeito de dois tipos de preparo de solo; realização ou não de gessagem; e quatro doses de calcário na produtividade da mandioca (IAC 12). O experimento foi desenvolvido em parcela subsubdividida com 24 repetições. Avaliaram-se dois tipos de preparo de solo um com arado e grade e o outro somente grade; gessagem (0 e 650kg/ha); e quatro doses de calcário (0; 600; 1000; 1400kg/ha). A colheita foi realizada 10 meses após o plantio e foi determinada a produtividade por planta. Foi realizada análise de variância e teste de Scott-Knott para comparação de médias. Verificou-se que não houve resposta significativa para nenhum dos tratamentos realizados
