- ÍtemAcceso AbiertoAdaptabilidad del hibrido de maíz P4021 con tres densidades de siembra en el cantón Oña, provincia del Azuay(Universidad Católica de Cuenca., 2024) Ullauri Sandoval, Marco Esteban; Vázquez Vázquez, Jacinto Enrique; 010455117Corn stands out as the sole cereal suitable for human and animal consumption. Climate change-related alterations suggest the search for alternative animal feed. This research aimed to assess the effects of planting density on the agronomic performance of the P4021 corn hybrid in the Oña canton, Azuay province. A Randomized Complete Block Design (RCBD) was used, consisting of four treatments and four replicates, with a total of 16 experimental units of 12 m2 each across a 448 m2 area. Four planting densities —20, 40, 60, and 80 cm between plants, all at 60 cm between furrows— were tested, with two seeds dibbled per hole. The results revealed that planting density significantly impacts the agronomic performance of P4021 corn. Although no significant differences were observed on variables like height and leaf count, there were statistical differences in the variable weight per treatment (kg), highlighting the T1 treatment (40 cm between plants) with a mean of 27.6 kg. The cost analysis considers the T1 treatment as the optimal choice for planting this hybrid, compared to the control treatment (T4). In conclusion, planting density affects Hybrid P4021 cultivation, with 40 cm between plants yielding the best results in terms of profitability in the cost of production analysis, resulting in a 170% increase, making the T1 treatment ideal for corn silage.
- ÍtemAcceso AbiertoEvaluación del efecto de cuatro combinaciones hormonales, dos concentraciones de medio en la micropropagación in vitro de tres cultivares de anturio (anthurium andreanum)(Universidad Católica de Cuenca., 2024) Guzhñay Leon, Fabricio Ivan; Gonzalez Rojas, Juan Carlos; 0104973714Anthurium andreanum is an ornamental plant of great popularity and acceptance in the floricultural sector due to the shape of its foliage and showy flowers. Unfortunately, conventional sexual and asexual propagation methods are not practical to achieve massive multiplication of this species. Therefore, this research aimed to evaluate the effect of four hormonal combinations, two concentrations of Murashige and Skoog (MS) culture medium, on the in vitro micropropagation of White, Pink, and Orange A. andreanum cultivar (cv.). In consequence, two protocols for disinfection of explants from leaves were tested; the first treatment constituted of 70% Ethanol for 30sec, 0.5% NaClO for 15 min; the second treatment was 70% Ethanol for 1 min, 1 and 0.5% NaClO, for 5 and 15 min respectively. The result was that disinfection protocol number one presented tolerable levels of contamination (20.04%) and browning (36.33%) compared to protocol number two, which showed exuberant levels of browning (97.11%). The optimal culture medium for the micropropagation of A. andreanum of explants from leaves was 50% MS supplemented with 0.5 mg/L−1 of TDZ and 0.2 mg/L−1 of 2-4 D. The Pink cv. exhibited 90% callus formation and 8.5 shoots/explant, the Orange cv. showed 88.3% callus and 3 shoots/explant, and finally, the White cv. only presented 2% callus formation. In future research, it is recommended to test low concentrations of Kinetin and Naphthaleneacetic Acid in White cv.
- ÍtemAcceso AbiertoRendimiento de avena forrajera iniap fortaleza 2020, con tres dosis de fertilización en función de las recomendaciones del análisis de suelo(Universidad Católica de Cuenca., 2024) Morocho Macas, María Jacqueline; Quinteros Rodas, Wilson Olmedo; 1104851538The INIAP-Fortaleza 2020 is a forage oat variety developed by the National Institute of Agriculture Research (INIAP, by its Spanish acronym) in Ecuador, mainly used in animal feed. Following soil analysis recommendations, this study aimed to evaluate the impact of three fertilization doses on the yield of INIAP-Fortaleza 2020 forage oat. It is an experimental research with a quantitative approach, with a randomized complete block design (RCBD) with 4 treatments and 4 replications, resulting in a total of 16 experimental units formed by 30 m2 plots, in which the oat was planted, with the assistance of a seed drill. According to the results, there are no significant differences for the agronomic variables under study; however, it is observed that treatment 3 (20% additional) presents a higher average yield of fresh matter and plant height with average values of 2562.00 g and 77.52 cm respectively. The research concludes that although there were no statistical differences, several aspects of crops should be evaluated, since the soil often has optimal properties for the crop.
- ÍtemRestringidoRescate de una bebida ancestral de granos andinos tipo café elaborado por la Asociación Jatari Warmi(Universidad Católica de Cuenca., 2024) Santos Peralta , Alex Fabricio; Maldonado Cornejo, Manuel Esteban; 0107180994The Agroecological Association Jatari Warmi, located in the parish of Jadán, canton Gualaceo, province of Azuay, is a group of women agro-producers that promote practices to enhance the popular and solidarity economy through agroecological and sustainable food production. This study focused on promoting an ancestral beverage made from grains produced by the Association through its internal processes. To achieve this, post-harvest practices and seed conservation were investigated to determine their applicability in producing coffee-like beverages. In order to add qualitative value to the product for its establishment in the market, an internal product development process was established with the members, and an organoleptic evaluation was conducted with the public, together with a nutritional evaluation of its composition. Finally, its potentialities were consolidated, resulting in the development of a commercial product, "APU BY JATARI WARMI," which can be sold at Agroecological fairs and integrated into the Association's commercial portfolio, thus becoming one of the possible flagship products of the Association and generating higher profit margins. It was concluded that when developing a food product based on a recipe passed through generations, the use of techniques and knowledge specific to the environment is crucial and must be respected in all aspects, avoiding the gentrification of the process and thereby increasing its quality without interfering with the customs of the community, preserving knowledge and fostering fair trade.
- ÍtemAcceso AbiertoAislamiento y caractrización molecular de hongos (ecto y endo) micorrizicos asociados al cultivo de maíz (Zea mays L.) en el bosque seco del sur del país(Universidad Católica de Cuenca., 2023) Galarza Riera, Christian Andres; Salazar Orellana, Marjorie Jazmín; 0105846596This research aimed to evaluate the diversity of fungi in the rhizospheric soil of maize grown under different agricultural practices in the Pindal canton, Loja province, Ecuador. Soil and root samples were collected from two experimental sites under the three agricultural practices: planting, urea application, and burning. The samples were analyzed by molecular techniques to identify the presence of fungi. The results indicated that the rhizospheric soil of the two experimental sites showed a high fungi diversity. A total of seven fungal species were identified in the soil and 28 fungal species in the maize root. Metagenomic analysis of the soil revealed seven bacterial classes, 16 fungal families, and four species of mycorrhizal fungi. The functions of the fungi present in the root and soil were classified into 15 groups. The composition of the fungal community colonizing the rhizospheric soil varied according to agricultural practices. The rhizospheric soil of the dry forest had a higher diversity of fungi than the rhizospheric soil of the experimental sites with agricultural management. Finally, soil chemical and physical properties varied according to agricultural practices. The results demonstrate that the rhizospheric soil of the corn crop is a complex environment with a high diversity of fungi. Agricultural practices can affect the composition of the fungal community, colonizing the rhizospheric soil, which can impact on crop yield and quality. Keywords: microbial community, mycorrhizae, metagenomics, agricultural practices.
