    The main use of the mulberry at world level is like food of the silk worm, but depending on the town, it is also appreciated by its fresh consumed fruit, in juice or in preserves, as delicious vegetable, for its medicinal estates in infusions, for paisajismo and eat animal forage. The bases allow the anchorage of the system radiculars, playing a support part for the plant, it can intervene or not in the process of the nutrition of the plant. The vegetable hormones have to do mainly with the stimulation of roots, increase of the flotation, maturation of the fruit and, in it generates with the growth and development of the plant and their organs. This investigation was carried out the farm of State University of Bolívar CAEDIS Echeandía, located to an altitude of 600 msnm, temperature average of 25°C, annual precipitation of 2.300 mm and a relative humidity of 90% The objectives that thought about in this investigation were: i) Evaluate the apprehension percentage and quality of the mulberry plant agronomical with three types of bases and two types of hormones. ii) Determine the treatment that presents bigger apprehension percentage in the mulberry cultivation. iii) Determine the effect of three types of bases and two types of hormones in the quality of the mulberry plant. iv) Carry out a benefit-cost economic analysis B/C. An experimental design of complete blocks was used at random in factorial arrangement of 3x2+1 witness with three repetitions. The factor A: corresponded to 3 types of bases, A1: Fuzz of Rice 50% + earth of place 50%; A2: Fuzz of coffee 50% + earth of place 50% and A3: earth sowed 50% + earth of place 50%. The factor B was two types of hormones B1: Hormonagro and B2: Bio root, six treatments and a witness were had. They were carried out chemical analysis of bases, variance analysis, test of Tukey to 5%, main effect for types of hormones, correlation analysis and lineal regression, benefit-cost economic analysis B/C The main obtained results were:  Significant statistical differences were calculated for most of the variables evaluated in the asexual propagation of mulberry.  The basis with the highest percentage of the apprehension of mulberry plants to the 90 days was the A1: Fuzz of Rice 50% + earth of place 50% with 85%; followed by the A3: Earth sowed 50% + earth of place 50% with 81%.  The hormone Hormonagro, had a bigger effectiveness as for the variable percentage of apprehension of mulberry plants to the 90 days with 82,00% comparative to Bio roots that presented 79,00%.  In the interaction of factors types of bases for types of hormones the most effective treatments were the T1: A1B1 (Fuzz of rice 50% + earth of place 50% + Hormonagro) with 96,00% and the T2: A1B2 (Fuzz of rice 50% + earth of place 50% + Bio roots) with 85,00% to the 90 days.  The variables that contributed to increase the apprehension percentage significantly from the mulberry stakes to the 90 days were the height of plants to the 60 and 90 days and the width from the limbo to the 90 days.  The relationship benefit-cost in the production of mulberry plants in asexual form, by means of the use of bases and hormones, in all the treatments is superior that the unit, guaranteeing us a good profitability in this activity. The treatment with the best RB/C was the T7 with $. 5,56
