    Evaluación de cuatro sustratos y dos fitohormonas en el prendimiento de estacas de caña guadúa (Guadúa angustifolia) en el sitio el Mirador, cantón Echeandía, provincia Bolívar

    In the world, you begin to look to the cane guadúa like an ecological alternative, since its use in several productive processes would reduce the impact on the native forests, because the guadúa can be a substitute of the wood. This investigation was carried in the Mirador, Echeandía city, Bolívar state, to an altitude of 600 mls. The objectives outlined in this investigative work were: i) Evaluate the effect of four bases and two fitohormonas in the asexual propagation of guadúa plants in nursery. ii) Determine the effect of four types of organic bases on the apprehension of guadúa plants in nursery. iii) Measure the answer of two types of hormones in the asexual propagation of guadúa plants in nursery and their effect in the apprehension components and survival of plants. iv) Carry out a budget economic analysis partially and Marginal Rate of Return (TMR%). A design of Complete Blocks was used at random (DBCA) in factorial arrangement 4x2. Factor A corresponded to four types of bases: A1: Earth of Guabo, A2: Humus of Worm, A3: Shell of Cocoa and A4: Earth of the Place. The Factor B was two types of hormones B1: Cytokin and B2: Rootmost. Eight treatments were had with three repetitions. They were carried out variance analysis, main effect for types of hormones, test of Tukey for factor A, Types of bases and interactions AxB. Correlation analysis and economic of budget partially and calculation of the TMR%. The more important results were: The basis with the percentage of survival of higher guadúa to the 90 days was the A1: Earth of Guabo with 89,67%. The hormone with the biggest percentage of survival of guadúa plants to the 90 days was Cytokin with 79,17%. In the interaction of factors AxB, the highest percentage of survival in plants was evaluated in the T 1: A1B1 (Guabo Earth with the hormone Cytokin) with 90,33%. The independent variables that contributed to obtain a bigger percentage of survival of plants to the 90 days were: percentage of apprehension of plants to the 30 and 60 days, height of the bud to the 60 and 90 days, diameter of the shaft to the 90 days and root volume to the 90 days. Economically the treatment with the highest net profit was the T5: A3B1 (Shell of cocoa with the hormone Cytokin) with $. 44,48 and a value of TMR of 37%. Finally this study contributed to improve the asexual propagation of cane guadúa, 123 having plants of good quality, very developed and in smaller time, with 60 days less in relation to the one to conventional propagation, that makes more competitive the activity of the viverista
