Production of Papaya Seedlings Using Spirulina platensis as a Biostimulant Applied on Leaf and Root
Open accessAbstract
Aims: This study evaluates the influence of Spirulina platensis concentrations on the growth and quality of papaya (Formosa Group) ‘Tainung-1’. Study Design: The experimental design was completely randomised, with plots subdivided over time. Place and Duration of Study: From April to June 2017, two greenhouse experiments were carried out at the Agro-Food Science and Technology Center of the Federal University of Campina Grande, Pombal-PB, Brazil. Methodology: We carried out two greenhouse experiments in completely randomised designs, one with the application of S. platensis on the leaf and other with an application on the root. In both experiments, the treatments consisted of six biomass concentrations of S. platensis (0.0, 0.4, 0.8, 1.2, 1.6, 2.0%). Results: At 52 days after sowing, we measured the following variables: growth, production of dry and fresh mass of roots and shoot, and the seedlings quality index. The modelling functions predict that the suspensions with 1.08% of S. platensis applied on root may provide the best growth and biomass production of the seedlings. However, suspensions of S. platensis applied on leaf were inefficient in the improvement of seedling quality. Conclusion: When applied to the roots, a suspension of 1.08% S. platensis increases the growth and biomass production of the seedlings; and when used in the concentration of 0.88% improves the quality of the 'Formosa' papaya seedlings. Suspensions of S. platensis applied on leaves do not affect the growth and quality of seedlings of papaya.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
