COSTA JUNIOR, Euvaldo de Sousa et al. Production of Carica papaya seedlings, formosa type, with buriti stem residues (Mauritia flexuosa L.f.). Rev. de Ciências Agrárias [online]. 2017, vol.40, n.4, pp.50-59. ISSN 0871-018X.  https://doi.org/10.19084/RCA16152.

Papaya is a fruit that is highly consumed worldwide. The objective of this work was to evaluate the quality of Carica papaya seedling with buriti (PaB) residue. The experiment was conducted at the State University of Piauí (UESPI), Corrente, PI. A completely randomized design (DIC) was used, consisting of five treatments and six replicates: T1 - soil (10 L); T2 - soil: burití wood (10 L: 1.5 L); T3 - soil: burití wood (10 L: 3 L); T4 - soil: burití wood (10 L: 4.5 L); T5 - soil: burití wood (10 L: 6 L). The results were submitted to the F test at p <0.01 of significance, for diagnosis of significant effect. The variables analyzed were: seedling height, stem diameter, root length, number of leaves, total leaf area, shoot dry mass, root and total dry matter, plant height / stem diameter ratio and dry mass of root shoot / root dry mass and Dickson quality index. The introduction of 30% buriti wood into the substrate is recommended for the production of "formosa" papaya seedlings. The Dickson quality index for papaya is 0.55 with 37.5% buriti stick.
