In the State of Mato Grosso do Sul, the cultivation of fruits is limited of consistent information, concerning the potential for production of seedlings for field production. This work evaluated papaya seedlings biomass production in different environments, pots, and substrates in the State University of Mato Grosso do Sul, Aquidauana - MS, Brazil, from September to November, 2006. The cultivation environments were: greenhouse with low density polyethylene film; nursery with monofilament black screened; nursery with aluminized screened and nursery with straw of native coconut palm. The substrates "soil + organic compost + vermiculite", "soil + organic compost + sawdust" and "soil + organic compost + vermiculite + sawdust" filled the polyethylene bags and polystyrene trays. The experiment consisted of a completely randomized statistical analysis in split-split-plot. The environment with aluminized screened promoted the greatest biomass accumulation for the polyethylene bags. The polyethylene bag was the best pots for papaya seedlings production. The substrates containing vermiculite promoted greater biomass in polyethylene bags. The environments with aluminized screened promoted greater leaf dry mass in the three substrates compositions.
