Culture of Cherry Tomato Treated with Pyroligneous Acid.

The main goal of the present work was to evaluate the effects of Pyroligneous Acid (PA) on nutrition, yield, classification and characteristics of taste (total soluble solids and titratable acidity) in the cherry tomato plants grown in soil treated with five concentrations of PA (0; 1; 2; 4; 8% v/v), and as for the presence and absence of shoots PA spraying (0.1% v/v). The experimental design was completely randomized in a factorial scheme (5 X 2), with four replications. The variables analyzed were: soil chemical properties, shoots dry mass, stem diameter, leaf area, foliar nutrient accumulation and foliar levels, fruit titratable acidity (TA) distribution and total soluble solids (TSS). The application of PA in the soil caused no change on soil chemical properties. The soil concentrations PA and aerial spraying did not influence the tomato, total dry matter accumulation, leaf area and stem diameter, but acted in different ways on foliar levels and nutrients accumulation. The spraying of 0.1% (v/v) of PA in the aerial portion increased the production of small fruits and the application of 8% (v/v) of PA reduced giant fruits yield. Fruits total number and the total fresh mass were not influenced by application of up to 8% of PA on soils and spraying of aerial portion. The TA and TSS were not influenced by the application of PA on soil and spraying of aerial portion of cherry tomatoes.
