This work was carried out in a greenhouse of plant formation at Campus of Universidade Federal de Lavras, UFLA, Minas Gerais aiming to evaluate different doses of organic compost and simple super phosphate in papaya 'Formosa' seedling. It was tested in Red Latosol distrophic four doses of simple super phosphate 0,0; 2,5; 5,0; 10,0 kg m-3 of substrate, with 180 g of P2 O5 per kg-1 and four percentages of organic compost 0%, 10%, 20%, and 40% of total volume. A randomized block design was used with factorial scheme 4x4, with four replications and five plants by plot. It was evaluate the following characteristics: high of plants (cm), root length (cm) number of leaves/plants, dry matter of aerial part and root (g/plant). The results showed that the use of simple super phosphate at 10kg m-3 in substrates warranty best quality in plant formation of papaya Formosa. The organic compost at 40% in substrates showed is a viable alternative in organic matter for plant formation of papaya.
