Estudo do nível de cianetos em 4 variedades de mandioca sob diferentes condições de irrigação

Abstract

In order to study the fluctuation of the cyanide level in cassava under irrigation and another under rainfed conditions, this work was carried out, using 4 varieties of cassava, namely, TMS 42025, MZ 89001, Gangassol and TMS30395. These varieties were subjected to 3 levels of irrigation, on the first level called L3 the plants were fully irrigated, on the second level they were partially irrigated and on the third level they received water in minute quantities that could be considered to have been in dry conditions. The HCN analysis was performed using the method of Bradburgy et al, (1998), 144 analyzes were performed in 48 sub-samples, the treatment included analysis of variance and the Duncan test. The results of the data treatment showed that the varieties concentrated larger amounts of HCN in the irrigation level considered as rainfed.(TRADUÇÃO NOSSA)
