Objective: evaluating the productivity of mother plants and the rooting percentage of cuttings of Eucalyptus grandis, Eucalyptus urophylla and Eucalyptus urograndis. Design: Ten clones of each species were evaluated in a clonal miniature garden in a gutter system fitted with drip irrigation. Results: The assessed number of sprouts and viable cuttings variables registered high significant differences (P <0.0001) between clones: UP1 (17,947 shoots and 34.05 viable cuttings), UG2 (12,120 shoots and 22.96 viable cuttings) and G2 (10,254 shoots and 23.96 viable cuttings). Regard the measured parameters in the irrigation water, the average values of EC 0.5 mS/cm and pH 5 to 7 were obtained. The stem cuttings established in the module had high significant differences (P <0.0001) in terms of the rooting percentage.  Three clones were superior, the best of which, clone G2, reports 78.58% rooting, which developed in environmental conditions of relative humidity greater than 80% and temperature between 25-30 ° C. Findings/conclusions: With the obtained values from the measured variables, a rooting productivity projection was carried out considering a 54 mother plants / m2 density, resulting in a minimum average annual production of viable cuttings from 10,000 to 27,000 depending on the clone, with 2,000 to 18,000 cuttings with rooting possibilities per square meter.

Six leguminous species Frijol bayo (Vigna unguiculata), Frijol white Var. Orituco, Quinchoncho dwarf (Cajanus cajan (L.) Millsp., cv. Aroita), Kudzú tropical (Pueraria phaseoloides), Crotalaria (Crotalaria juncea), Sesbania (Sesbania grandiflora) were established in an agroforest systems to assess his effect on the chemical property of a Alfisol soil at municipality Ospino Portuguese state, at the farm La Yaguara planted with E. urograndis. In a design in random blocks with 7 processings and 4 repetitions, employing STATIXTIS 9.0 to carry out the ANDEVA and for variables where differences are presented the test was employed of Tukey (5%); obtaining as results that in the soil of the farm The Yaguara alone significant differences were found (P<0,05) for the variables relation C/N, CO, Zn, highly significant and differences (P<0,01)for N; being the Sesbania and quinchoncho the best treatment in relation C/N; for CO the frijol blanco and the treatment control; for Zn the quinchoncho and treatment control, frijol blanco and kudzú tropical; in the N quinchoncho and Sesbania. To confirm the generated profit to the agroforestry system analysis were completed foliate to the eucalyptus, finding highly significant differences for P with Frijol blanco and Kudzú and significant for Zn where is quinchoncho and treatment control.
