Colección y selección de gramíneas y leguminosas nativas y naturalizadas en cuatro cantones de la provincia de Zamora Chinchipe para formar un banco de germoplasma promisorio en la estación Experimental El Padmi

Were selected and collected grasses and legumes Zamora cantons, Centinela del Condor, The Pangui and Yantzaza to form a seed bank, with the aim of improving livestock production systems in the province of Zamora Chinchipe. The objectives were: to collect grasses and legumes native and naturalized and identify morphological attributes and productive accessions characterized and evaluated at the Experimental Station "The Padmi" National University of Loja and evaluate their nutritional value and disseminate results to farmers, technicians, teachers, students. By transect walks and use of key informant collected 33 grasses and 12 legumes planted in the The Padmi, in 104 plots of 10 x 4 m. The results concluded that: the variable percentage of seizure, the maralfalfa grass (Pennisetum violaceum) reached 92.5% and the legume indigofera (Indigofera suffuticosa) 80.0%, the best grass height at 60 days corresponded to German grass (Echynochloa polystachya) with 67.0 cm between the pulses was the moringa (Moringa oleifera) with average height 71.5 cm, on the average thickness of the stem stressed sugarcane forage grasses (Saccharum officinarum) with 14.20 cm and between the porotillo with spina legumes (Erythrina ulei) with 9.9 cm, the best average of tillering in grasses corresponded to dallis grass (Brachiaria decumbens) with 17 tillers per plant, in legumes the best was the peanut (Arachis pintoi) with 5 tillers, there were no pests or diseases in grass and legume species studied, the best average length and width of the leaf in grass species occurred in forage cane (Saccharum officinarum) to 108.5 cm in length and 3.95 in width, between the best average pulses corresponded to porotillo spina (Erythrina ulei) with 5.05 cm long and 3.0 cm wide in the biomass yield grasses was average at best forage sugarcane (Saccharum officinarum) with 116 t / ha, and in legumes groundnut (Arachis pintoi) with 12.53 t / ha, in the best average carrying capacity it reached maralfalfa grass (Pennisetum violaceum) with 6.20 UBA legumes and peanuts (Arachis pintoi) with 0.76 UBA, in relation to the nutritional value porotillo with spina species (Erythrina ulei) 21.50% protein and fiber 29.00% reached the highest nutritional value. After completing the study were considered promising species porotillo the legume and grass boneless maralfalfa, for its high content of protein, fiber and biomass production.
