Résumé:
Moringa oleifera Lam. Has been widely studied for its diverse applications and benefits.
Resistant to drought, this plant has been satisfactorily adapted to the edafoclimatic conditions
of the Brazilian Northeast. Information on the nutritional requirements of this plant is relevant
in view of the high development potential in the semiarid region. The objective of this study
was to evaluate the effect of organic fertilization on plant growth, fruit production and moringa
root system. The experiment was conducted in the Forage Sector, in an experimental area of
the State University of Paraíba / UEPB / Campus IV - Cashew, located in the municipality of
Catolé do Rocha / Paraíba. For the growth and fruit production evaluations, the experimental
design used was randomized blocks, with five treatments, corresponding to the doses of bovine
manure (0.0 g, 300 g, 600 g, 900 g and 1200 g), with four replications. The experimental plot
consisted of 12 moringa plants with 3.0 m x 3.0 m spacing, with only eight central plants being
evaluated. A randomized block design in a 5x2 factorial arrangement was used for the study of
the root system, corresponding to five doses of bovine manure (0.0g, 300g, 600g, 900g and
1200g) and two depths (0-10 cm ; 10-20 cm) in four replicates. The experimental plot consists
of 04 central plants. The variables height and diameter and fruit yield of the moringa plants
were not significantly affected by the different doses of bovine manure used. The moringa
plants developed satisfactorily in the semi-arid conditions of Catolé do Rocha-PB. The doses
of bovine manure did not influence the length and density of moringa roots. The organic
fertilization for the moringa crop must be carried out in the superficial layer of the soil, up to
10.0 cm deep.
