Cultivation of cassava with use of organic fertilizers and their effect on industrial quality of roots

Abstract

The objective of this study was to evaluate the organic fertilization in cassava cultivation and its
effect on the industrial quality of the roots. The research was carried out in the municipality of
Garanhuns, State of Pernambuco - Brazil, in a randomized block design, and in a sub-subplot
(4x2x4) scheme, consisting of four leguminous plants in the plot (jack beans, crotalaria, dwarf
pigeon peas and cowpeas), presence or absence of organic compost in subplots, and four
concentrations of biofertilizer in sub-subplots (0, 5, 10 and 15%). The analyzed variables were:
starch content and yield of cassava flour. The data were submitted to analysis of variance and
treatment means were compared by Tukey test (p <0.05). For the study of biofertilizer concentrations,
regression analysis was utilized. Green manure from cowpeas increased the industrial
quality of cassava roots.
