MANEJO DE ADUBAÇÃO NA CULTURA DA MANDIOCA (Manihot esculenta Crantz).

Abstract

One of the most important sources of energy in the carbohydrate form, cassava stands out economically, both nationally and in other Latin American countries. This plant has the most important tropical subsistence crop, as well as being one of the plants with the best efficiency in the export of nutrients and energy production, being able to adapt to the soils with low fertility. However, domestic production is dominated by family and low-income agriculture, which adds a social bias in this work and justifies research with this culture to determine techniques and practices that help the producer. The objective of this work was to evaluate the development of table manioc under the effect of organic fertilization, mineral and with the Ubyfol rooting. The experiment was carried out in the Pirpiri Site Community, Mari municipality, a micro region of the Zona da Mata Paraibana, using randomized blocks (DBC), with four replications. The experimental design was in randomized blocks, with the following treatments: (T0) without fertilization, (T1) poultry manure, (T2) silage foliar fertilization, (T3) conventional fertilization, (T4) bovine manure and (T5) rooting Ubyfol . An evaluation of the Variables: stem diameter, plant height, number of shoots, total shoot weight, length, root diameter and total weight and strain weight. It was observed that conventional fertilization (T3) is among the evaluated treatments the best cultural tract for cassava production in the rainforest in the studied region, since it promoted an increase in root and shoot weight. The other treatments did not show significant increases.
