Resposta da Mimosa caesalpiniaefolia ao substrato enriquecido com resíduo da carcinicultura oligohalina

Abstract

The growth of shrimp farming with oligohaline waters is an activity that is developing with great notoriety in the hinterland region of Ceará, and despite being an economically viable enterprise, river environments, when poorly managed, alter the biochaeochemical conditions of the environment and can lead to contamination. of natural water resources. Another problem is the removal of vegetation and installation of tanks in protected areas. Therefore, there would be a double gain, since the waste was disposed of correctly, with losses and costs associated with the acquisition of external organic waste to be used in forestry replacement projects. Know whether the potential of these residues is relevant to their use as a soil conditioner. The general objective of this work is to verify the effect of shrimp farming extinguishing doses added to a substrate on the growth, development and carbon content of Sabiá (Mimosa caesalpiniaefolia). Methodologically, an experiment was installed in a greenhouse at the Meteorological Station of the Department of Agricultural Engineering of the Federal University of Ceará (UFC) located in the municipality of Fortaleza-CE. The experimental design was in randomized blocks with 5 (destruction doses) x 1 legume, Sabiá (Mimosa caesalpiniaefolia Benth) with four replications, totaling 20 experimental units. Growth assessments and determination of Carbon content were carried out in the aerial part and root of the plant. There were significant effects for PSPA, PSR and Height. Like other variables, diameter, COTPA and COTR did not have a significant effect. It is concluded that the extinction of shrimp farming favored the initial growth of Sabiá based on evaluated parameters, therefore it can be used in forest restoration or recovery of degraded areas.
