Response of cassava to different types of soil preparation

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.
