Résumé:
The yellow passion fruit Passiflora edulis Sims. f. flavicarpa Deg., belonging to the
Passiforaceae family, is among the main fruit species cultivated in Brazil. The work aimed to
evaluate the influence of different percentages of bovine manure in the production of passion
fruit seedlings, to investigate the initial growth of the seedlings, to identify which percentage
provides the shortest period for planting the seedlings in the field and to observe the occurrence
of pests and diseases . The experiment was conducted in the field from march to july 2020,
Jaçanã, RN. The seedlings were produced in polyethylene bags. The experimental design was
completely randomized, with treatments called T1 as control with 100% soil in the substrate,
T2 with 90% soil + 10% bovine manure, T3 - 80% + 30%, T4 - 70% + 30%, T5 - 60% + 40%
and T6 - 50% + 50%, respectively of soil and manure. Plant height, stem diameter and number
of leaves were evaluated. The data were subjected to analysis of variance and the means
compared by the Tukey test at 5% probability. The substrates provided satisfactory results
regarding seed germination. In the initial growth phase, there was no significant difference in
treatments, as well as in the second analysis. It can be seen that at the end of the experiment the
investigated variables behaved similarly in the T3, T4, T5 and T6 treatments, not differing
statistically, but with a significant difference from the T1 control. It was concluded that the
morphometric performance of passion fruit seedlings stood out in relation to Treatment 6, with
a higher percentage of bovine manure, the initial growth of the seedlings was increased as the
percentage of bovine manure was added, even though there were no significant differences
between the two. treatments. The percentage of 50% of bovine manure in the substrate provided
a greater increase in the variables investigated, plant height, collection diameter and number of
leaves, despite being statistically equal to treatments 3, 4 and 5. The occurrence of pests and
diseases did not reached crop damage level.
