The study aimed to evaluate the influence of solid manure (MBR 34) and leaf (AX) based on shale in the production and quality of strawberry cultivars Camarosa and Camino Real. The experiment was conducted in a private property located at Estrada da Gama, 9th District of Pelotas / RS in the period from May to December 2009. The cultivars were Camarosa and Camino Real, conducted in three rows, spaced 0.30 mx 0.30 m under low tunnels and drip irrigation. For each cultivar experiment was performed with a split-plot design by block, with four replications. The solid manure factor (S) with two levels: presence and absence of 500 kg ha-1 in MBR 34 (particle size 100% <0.3 mm) was allocated in the plot. In the subplot factor was allocated foliar fertilizer (F) with three levels: 0, 12 and 24L ha-1 water shale + 10% Ca (calcium nitrate, 14% N and 18% Ca) + 2% B (boric acid, 17% B). Were also employed two additional treatments (control). The experimental unit of the factor plot consisted of 12 plants. The variables analyzed were number of fruits per plant, fruit weight (yield) per plant, weight per fruit, leaf chlorophyll content, soluble solids, total acidity and herbal compounds, which are, anthocyanins, phenolic compounds and antioxidant activity . Was also performed chemical analysis of soil and foliar. Data were subjected to analysis of variance followed by comparison tests of means or polynomial regression analysis. To cultivate Camarosa, concluded that: the leaf manuring and solid manure did not influence the variables of production and chlorophyll content, it is possible that under the experimental conditions, the high levels of nutrients in the soil did not permit the performance expected for the treatments, the antioxidant activity of fruits was higher in the presence of solid manure, the concentrations of phenolic compounds were reduced according to foliar and anthocyanin contents were not affected by treatments, the content of soluble solids was higher in the presence of solid manure (MBR 34), while the acidity of this variety was not affected by treatments. To cultivate Camino Real, increasing the dose of AX, on average, promoted an increase in mass per fruit, the chlorophyll content were not affected by treatments, the Camino Real cultivar proved to be benefited by the element manganese in the soil, especially in the presence MBR 34; generally the nutrients P, Mn, Ca, Mg, Zn and Cu were positively correlated with the variables of production of this cultivar, the nutrient potassium and manganese were elevated in soil, however, remained on the stalk It is within the proper range, the functional characteristics of strawberry are influenced mainly by adverse conditions of culture medium, the content of soluble solids was higher in the presence of solid manure (MBR 34), while the use of foliar fertilization resulted higher levels with the control that was superior to other treatments in the presence of MBR 34.
