PAIXAO, Marcus Vinicius Sandoval et al. Organic and mineral fractions in the production of papaya seedlings. Rev. Bras. Frutic. [online]. 2012, vol.34, n.4, pp.1105-1112. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452012000400018.

The objective of this study was to evaluate the effect of different dosage of chicken manure associated with the superphosphate fertilizer, replacing the formulation used in the north of Espírito Santo, the production of 'THB' papaya seedlings. The experiment was conducted in an agricultural nursery, of the Company Caliman Agricola SA, in Linhares-ES in randomized block design in a factorial 5x5 (superphosphate: 0, 5, 10, 15, 20 kg m-3 x chicken manure: 0, 10, 20, 30, 40% v / vt) with additional witness consisting of the standard mixture used in the region with 3M® mini Basacote fertilizer, NPK (mg) 13-06-16 (1.4) with micronutrients (10% S, 0.05% Cu, 0.26% Mn, 0.015% Mo) at a dosage of 10 kg m-3, with 4 repetitions. The substrate was Bioplant®. It was evaluated the % of emergency, the emergency speed index and the emergency average time, the rate of chlorophyll content, seedling height, stem diameter, leaf number, root length, dry mass of roots and shoot. It is concluded that the standard treatment of substrate and fertilizer Basocote Bioplant®, presented itself as the best for production of 'THB' papaya seedlings and discouraged the use of chicken manure mixed with the substrate. The application of superphosphate fertilizer did not improve the quality of the seedlings from the default.
