RESUMO:

The search for inputs adapted to organic agriculture has increased due to the interest of the society for healthy food. The use of available organic residues represents an alternative for organic agriculture needs, since they are bioestabilized by composting. The objective of this dissertation is to prospect organic residues, evaluating the effect of  composts prepared with them in the cultivation of lettuce. Initially, farmers from Mogi das Cruzes and Suzano were interviewed about organic residues which may be used as fertilizers. Residues of mushroom production, and poultry, quail and cattle manure presented higher amounts of nutrients and potential of use as fertilizers. During composting process, it were observed that composts prepared with manures reached temperatures above 50°C. It were evaluated eight composts for organically grown lettuce, prepared with the residues: (i) Grass + Cattle manure; (ii) Grass + Quail manure; (iii) Grass + Poultry manure; (iv) White Shimeji compost; (v) Black Shimeji compost; (vi) Shimeji compost + Quail manure; (vii) Shimeji compost + Poultry manure; (viii) Control treatment. The adopted statistical design was randomized blocks, with three replications. The organic composts applied to lettuce promoted higher fresh shoot biomass production in reltion to control treatment, except for the White Shimeji compost. The treatments Shimeji compost + Quail manure and Grass + Cattle manure promoted higher production of lettuce. The use of composted organic residues has shown efficient results for organically grown lettuce.
