Likewise, the complexity and multidimensionality of sustainability make it necessary to turn complex aspects into clear, general and objective values, called indicators. The inputs and services used in plant production represent an energy cost, depending on these factors and the productivities obtained, the conversion of production into energy will determine the energy efficiency of the system. The objective of this study was to evaluate the sustainability of small and medium-scale horticultural production systems in the San Joaquin parish of Cuenca, using sustainability indicators established by Altieri and Nicholls (2002) and Funes (2009). The methodology adopted included the gathering of information through surveys conducted in a direct interview with horticultural producers. The results showed that horticultural farms exceed the threshold of soil and crop sustainability with values of 7.79 and 5.84 respectively, however there are indicators that showed a deficit, such as the surrounding natural diversity where 97% of farms have values <5 below the threshold of sustainability, and therefore require management to improve them. In the horticultural systems of San Joaquín 98% have an energy efficiency > 1. The crops that presented the highest annual EfE were garlic (7.71) and carrot (5.35). In conclusion, in the San Joaquín parish, the evaluated farms show a tendency toward sustainability and good energy efficiency.Item Evaluación de tierras con fines de riego para pastizales extensivos e intensivos en la granja de Nero(1998) Sánchez Viteri Henry; Alvarado, Paúl; Cevallos Becerra, ClaudioItem Evaluación de tres sistemas de riego en la producción de tres tipos de pastos hidropónicos(1997) Delgado A., Pablo; Contreras Rivera, Jorge EduardoItem Evaluación del efecto de inoculantes de suelo nativo y raíces de Macleania rupestris en dos sustratos sobre el crecimiento de plántulas de la misma especie(Universidad de Cuenca, 2024-08-06) Luna Avila, Daniela Nicole; Mendieta Gutiérrez, Luis Ángel; Peña Tapia, Denisse FabiolaMacleania rupestris, commonly known as joyapa, is a native plant belonging to the family Ericacea, known for its benefits both for human health and for the sustenance of the ecosystems in which it grows. Finding substrates where this species is correctly established is of utmost importance for its domestication, besides, understanding the microorganism substrate interactions is important to understand how the endophytic microbial colonies of root, surrounding soil and rhizospheric soil are related to the peat and fiber substrates where they are inoculated. As a method of study, the variables plant height and number of leaves were evaluated over a period of 4 months, and the biomass variable was evaluated only in the last data collection of the experiment. It was identified that the peat substrate establishes higher plant survival rates regardless of the inoculant used. In turn, the surrounding soil inoculum vehicle presented better rates of height increase denoting greater plant growth, while the peat plus root inoculant treatment denoted greater leaf production over the course of the trial. This study shows the effect of substrates on the production of joyapa seedlings and the potential of microbial inoculants in the domestication process of Macleania rupestrisItem Influencia de la poda de formación y distancias de plantación, en la producción de tomate de árbol (Cyphomandra betacea Cav-Seend)(1996) Ortuño Rivera, Jorge R.; Santillán Santillán, FranklinItem Influencia de las variables ambientales sobre la fenología de 10 especies forestales nativas, de la Granja Experimental de Nero, cantón Cuenca(2018-11-19) Eras Chacho, Ronal Manuel; Pintado Muy, Christian Roberto; Jadán Maza, Ángel OswaldoIn Ecuador there is little information on the forestry knowledge of native species that allow having technical and scientific tools to use them within reforestation and ecological restoration plans. For these reasons, it is important to carry out different technical activities such as phenological studies to design calendars, especially for the collection of seeds. Under this background, the present study was developed whose objective was to evaluate the occurrence of the phenological phases of 10 forest species and their relationship with the environmental variables of temperature precipitation and heliophany. The native arboreal species studied were: Clethra fimbriata (Cletra), Escallonia myrtilloides (Chachaco), Ilex rupícola (Ilex), Myrcianthes rhopaloides (Arrayan), Myrsine dependens (Myrsine), Oreocallis grandiflora (Gañal), Oreopanax andreanus (Pumamaqui rojo), Oreopanax avicenniifolius (Pumamaqui blanco), Vallea estipularis (Sacha capulí), y Weinmannia fagaroides (Sarar). These are found in the forest of Granja Nero, belonging to the University of Cuenca. Methodologically, six individuals were selected for each species, with good phenotypic characteristics. The monitoring of these species was carried out every 15 days for a period of 26 months. In addition, the environmental variables of precipitation, temperature and heliofania were correlated with the phenological stages flowering and fruiting. Of the ten species Clethra fimbriata (Cletra), Escallonia myrtilloides (Chachaco), Oreopanax andreanus (Red Pumamaqui) did not show flowering and fruiting. However, those who did experience these phases did so in different months and with different intensity. The phenological phases of flowering and fructification of most of the species showed a greater correlation with heliophany. It was also observed that, during the study period, the flowering and fruiting of the ten forest species highlight their fertilityItem Problemas de transferencia tecnológica a sectores campesino indígenas: El caso del maíz en Patacocha(1998) Quinde P., Francisco; Ortega Vilela, EnriqueItem Respuesta del cultivo del fréjol (Phaseolus vulgaris L.) variedad panamito a diferentes niveles de fertilización(1990) Orellana G., Edgar; Larrea Calles, FernandoItem Sistemas de conducción en un cultivo establecido de granadilla Passiflora ligularis Juss. en Gualaceo(1993) Alvarado B., Pedro Orlando; Larrea Calles, Fernando
