ESPAÇAMENTO E DOSES DE FÓSFORO EM JOÁ DE CAPOTE

Abstract

The number of species with potential for the production of biodiesel is still small, so it is necessary to search for new ones, such as the capped joá (Nicandra plysaloides). This work had the objective of evaluating the possibility of using joá de capote as a supplier of raw material for the production of biodiesel. This work was developed in the experimental field and in the Soil and Vegetable Tissues Laboratory of the IF Goiano - Campus Rio Verde –GO, the planting of seedlings was carried out on 12/15/2016, in a factorial scheme (4x2) using a delineation in randomized blocks with 4 replications, totaling 32 experimental plots. Four doses of phosphorus were applied: control (without application), 40, 80 and 160 kg ha-1 of P2O5, using triple superphosphate and two spacings: 0.25 and 0.50 m between lines as source. There was an increase in the dry matter weight of the crop root, as a function of P2O5 doses. There was no significant effect on the spacing in the increase in the overcoat joá oil content. The vegetative development and productivity of the overcoat were influenced linearly by the factors of P2O5 doses.
