The objective of this study was to evaluate the effect of homeopathic preparations and crop environments through production and yield of flavonoid and saponin on carqueja plants. The experiment was carried out at the Department of Fitotecnia-UFV, from March/2010 to December/2010. It was a factorial (6X2) on completely randomized design with 5 homeopathic treatments: Silicea CH6, CH12, CH30, D7 and Equisetum D7 + control (70% ethanol) x 2 crop nvironments: greenhouse and shade 50% and 4 replicates, totaling 48 experimental units. The carqueja plants were produced by vegetative form from the same female genotype collected in Viçosa/MG. Cuttings of about 10 cm were placed in plastic tubets for rooting in greenhouse for 2 months. After rooting, they were transplanted into 1,5 L plastic bags with 3 parts of soil and 1 part of cow manure substrate and were put on differet crop environments to receive the homeopathic treatments. The treatment were applied at concentration of 25 drops/500 mL of distilled water using hand apryers. Each plant received approximately 10 mL via leaves. The preparations were sprayed always on mornings, three times a week on alternate days during two months (27/09/2010 to 27/11/2010). The interation between the factors as well as the independents factors were compared by the Tukey test at 5% probability. The effect of homeopathic preparations and the two crop environments on carqueja plants were evaluated through the variables: height (HRE), length of the longest branch (LLB), secondary shoots (SEC), fresh matter of aerial part (FMAP), dry matter of aerial part (DMAP), moisture content (MC), flavonoids content (QCT) and saponins content (SAP) in aerial part. The variables HRE, LLB and SEC were only affected by the crop environment factor. The variables FMAP, MC and QCT were significantly influenced by the crop environments, the preparations and interaction beteween the two factors. The DMAP was only influenced by the interation of the two factors and the SAP was only affected significantly by homeopathic preparations. The 50% shade environment associated with Silicea CH6 or D7 increased production and yield of quercetin. The highest yield of saponins was achieved with Silicea D7, independent of crop environments. The preparation Silicea CH30 was able to balance the moisture content in carqueja plants, according on crop environments.
