Abstract:                  The vainites are easy and tasty palatability, in human consumption, also help in the decoration of the gastronomy, which is a productive alternative of great importance for farmer.Foliar fertilizers can be used to optimize the production of this crop. These fertilizers of chemical origin have high prices in the market, this diminishes their profitability. The tea of foliar worm humus of organic origin and home production is an alternative available to producers and is important in the production with ecological orientation of crops. To achieve the proposed objectives, a randomized block design (DBA) was used with a two-factor or two-factor arrangement. The factors studied were "Variedades de vainite" and "Aplication te de humus de lombriz" which formed 8 treatments, each treatment had three repetitions, therefore, 24 experimental units were counted. To achieve the proposed objectives, a randomized block design (DBA) was used with a two-factor or two-factor arrangement. The factors studied were "Variedades de vainite" and "Aplication de humus de lombriz" which formed 8 treatments, each treatment had three repetitions, therefore, 24 experimental units were counted. Seven response variables were proposed, which are: Days to emergence, height of the plant, pod length, weight of pods, and number of pods, yield, and Preliminary Economic Analysis. The experiment was located in the Cota Cota experimental center of the Faculty of Agronomy of the University of Mayor de San Andrés (La Paz - Bolivia), occupyingan area of 30 m² under a protected environment, each treatment measured 0.9 x 0.9 m, in a cycle of cultivation of the vainite of 120 days and four applications of earthworm humus tea with a frequency of 15 days. The yield for the averages of the two varieties vainite was obtained a greater average in yield vainite (25% tea of humus of worm in water with variety V1 tail of mouse) that had the value 1193 g, followed by the treatment 3 (50% worm humus tea in water with V1 variety mouse tail) with 1077.3 g and finally treatment 7 (50% earthworm humus tea in water with V2 variety Bush blue lake 1061 g. The highest pod yield was 25% earthworm humus tea with 3672.8 g/treatment on average followed by 50% water worm humus tea that obtained 3577.15 g/treatment on average, 75% concentration earthworm humus tea which obtained 3074.9 g/ treatment of the average yield of pods of the vanilla and finally the treatments that did not apply earthworm humus tea, achieved an average of 3063.47 g/treatment. For the Benefit/Cost relationship it was determined that treatment 2 (V1 mouse tail variety and 25% earthworm humus tea) obtained a value of 1.76, which means that for each Bolivian invested, Bs0.76 will be earned; followed by treatment 7 (variety V2 Bush blue lake and 50% earthworm humus tea) with a benefit/cost of 1.64 which means that we will earn Bs0.64 and finally treatment 3 (variety V1) mouse tail and 50% earthworm humus tea) that achieved a result of 1.61 which tells us that Bs0.61 will be earned. It is better to use 25% earthworm humus tea in a V1 mouse tail variety, so that you have a better profitability in the production of vanilla under protected environment.
