The research was carried out in Querochaca Experimental Farm, Agricultural ciences Faculty, Ambato Technical University, located in Cevallos canton, Tungurahua province, with the purpose: two types stakes evaluating (without leaves T1 and with leaves T2), 1three plant extracts (2Aloe vera aloe E1, Lens culinaris lentil E2 and Salix alba willow E3) and two controls (Hormonagro phytohormone), in valerian (Valeriana sp) propagation, under plastic cover. The treatments were eight. The experimental design of completely randomized blocks (ANOVA) was used, in a factorial arrangement 2 x 3 + 2, with three repetitions. The variance analysis, tests of Minimum Significant Difference 5% and Tukey tests 5% were performed. The economic analysis was carried using the cost benefit ratio (RBC) methodology. The stakes without leaves treatments (T1), reported higher volume of the root system (0,91 ml at 45 days and 1,19 ml at 60 days), as well as better length (4,94 cm at 45 days and 7,55 cm at 60 days) and weight of the root system (0,45 g at 60 days). The leaf area was higher (2,35 cm2 at 45 days and 3,16 cm2 at 60 days), reaching the best percentage of rooted cuttings (93,06%). The aloe extract application (E1), produced highest volume of roots (0,97 ml at 45 days and 1,26 ml at 60 days), as best growth in root length (5,07 cm at the 45 days and 7,28 cm at 60 days) and greater weight (0,33 g at 45 days and 0,47 g at 60 days). The leaf area was better (2,40 cm2 at 45 days and 3,14 cm2 at 60 days), as well as the percentage of rooted cuttings (92,36%). From economic analysis was concluded that, among the treatments with the application of vegetable extracts, the extract of aloe in leafless cuttings (T1E1), presented the highest benefit-cost ratio of 0,22.
