Cut rose production constitutes one of the main economic activities of Ecuadorian agriculture. This research was carried out in a greenhouse at the Salache Campus of the Technical University of Cotopaxi and aimed to evaluate two biostimulants (Foliplus and Evergreen) and three application rates (0, 2 and 4 cc L⁻¹) on the vegetative growth and vase life of Freedom variety rose grafts. For this purpose, a randomized complete block design (RCBD) with a 2 × 3 factorial arrangement and three replications was implemented. The variables evaluated were plant height, stem diameter and vase life. The data were subjected to analysis of variance (ANOVA) and means comparison using Tukey's test at 5 % probability. From the data obtained, it was determined that the 2 cc L⁻¹ rate was the most efficient, with Evergreen (B2) being the biostimulant with the best performance; therefore, treatment T5 (B2 + 2 cc L⁻¹) was positioned as the most effective, reaching a floral stem height of 76.75 cm and a diameter of 8.37 mm. On the other hand, in the vase life evaluation, Foliplus (B1) recorded the longest duration with 16 days, surpassing Evergreen (B2), which reached a maximum of 15 days.

Sustainability is the ability of a production system to maintain its efficiency over the long term through the proper natural resources management, integrating economic, environmental, social, and technological dimensions. The Canal Norte Irrigation Board, located in San Lorenzo de Tanicuchí, Cotopaxi province, has 20 distribution intakes that supply approximately 930 hectare of agricultural land and serve 2,730 users. This research objective was to apply sustainability indicators to evaluate the economic, environmental, social, and technological dimensions on systems irrigation at North Canal Irrigation Board in San Lorenzo de Tanicuchí during the 2025–2026 period. This research was conducted using a quantitative and qualitative field-based approach, involving surveys, interviews, and direct observation. Sustainability was assessed using 16 indicators corresponding to the four dimensions, and the General Sustainability Index (GSI) was calculated by adapting Sarandón’s methodology. The results showed that the drip irrigation system achieved the highest IGS (2.46), standing out for its water usage efficiency and the rose growers’ ability to manage the system themselves; however, its main limitation was the high initial investment and maintenance costs. The gravity irrigation system achieved an IGS of 2.09, showing the average performance, with low investment costs and application ease in traditional crops; however, its main problem was water loss due to infiltration and runoff in the technological dimension. Finally, the spraying irrigation system recorded an IGS of 2.04, standing out for its uniform water application, which promotes forage growth, although it had limitations in the social dimension due to low user participation in management and its limited contribution to job creation. Overall, the Irrigation Board showed the average sustainability, highlighting the necessity to strengthen community management, modernization, and the efficient water usage resources. In addition, it was found that eight intake structures have maintenance problems, affecting the hydraulic infrastructure and compromising the system’s operational sustainability and reliability.

Evaluación de la tolerancia a la sequía de la variedad de trigo (triticum aestivum l.) INIAP-YURAK 2024 en dos tipos de suelo (franco y arenoso) bajo condiciones de invernadero
(Universidad Técncica de Cotopaxi (UTC) Ciencias Agropecuarias y Recursos Naturales. Agronomía, 2026-10-22) Chiluisa Astudillo, Yadira Aracely; Chancusig, Francisco Hernán; Garófalo Sosa, Javier Alberto
Wheat (Triticum aestivum L.) is a very important cereal worldwide due to its high consumption by humans and animals. In Ecuador, this crop is crucial to the economic livelihood of farmers. However, drought—a consequence of climate change—has become a limiting factor in the production of this cereal. The objective of this study was to evaluate the drought tolerance of the new wheat variety (Triticum aestivum L.) INIAP YURAK 2024 in two soil types (loam and sandy) and four soil moisture levels under greenhouse conditions. Eight treatments with four replicates were evaluated using a split-plot design, resulting in a total of 32 experimental units. The variables evaluated were: days to heading, plant height, spike length, number of grains per spike, number of tillers, number of spikes, dry matter weight, spike weight, grain type and color, yield, and yield loss. The data obtained were statistically analyzed using InfoStat software. The assumptions of normality and homogeneity of variances were first verified using the Shapiro-Wilk and Levene tests; analysis of variance (ANOVA) was performed, followed by Tukey’s test at the 5% level and Fisher’s LSD test. The results showed that soil type did not significantly influence plant height and yield of the INIAP-YURAK 2024 variety. It is concluded that the variety adapted well to both loam and sandy soils; however, adequate water availability is essential for achieving better agronomic and yield performance.

Evaluación de biochard como sustrato en la producción de plántulas de chocho (lupinus mutabilis sweet) quinua (chenopodium quinoa) y amaranto (amaranthus caudatus), en Salache, Latacunga, Cotopaxi 2026

In the Andean zone of Salache, Latacunga, crops of chocho (Lupinus mutabilis Sweet), quinoa (Chenopodium quinoa), and amaranth (Amaranthus caudatus L.) are traditionally established through direct continuous-flow sowing. Although practical, this system causes significant seed losses due to irregular seed distribution during sowing and the subsequent need for thinning. This study aimed to evaluate biochard as a substrate for seedling production of these three Andean species, determining the most efficient dose, the differential agronomic response, and economic viability. The methodology followed a quantitative, experimental approach under a completely randomized block design (DBCA), with four biochard treatments: 50 g, 100 g, 150 g, and a control without biochard; six replications and 24 experimental units per species. Results showed that the high dose of 150 g of biochard per kg of substrate favored all three species in key variables. In chocho: height 32.79 cm, stem diameter 0.58 cm, 47.83 leaves, root length 18.95 cm, and root volume 2.45 cm³. In quinoa: height 13.08 cm, stem diameter 0.36 cm, 8.17 leaves, root length 11.67 cm, and root volume 2.28 cm³. In amaranth: height 5 cm, stem diameter 0.32 cm, 4.83 leaves, root length 7.45 cm, and root volume 1.22 cm³. Cost–benefit analysis revealed a species-specific economic response: in chocho, the most profitable treatment was the high dose of 150 g of biochard, at $7.30 per six trays; in quinoa, the greatest economic efficiency was achieved with the medium dose of 100 g of biochard, at $6.40 per six trays; and in amaranth, the optimal treatment was the high dose of 150 g of biochard, at $7.40 per six trays. In conclusion, the use of biochard in nursery production offers a technically sound, economically viable, and sustainable alternative to optimize seedling production of Andean species and strengthen food security in the Salache area

This research project investigated the use of the Singapore Method in mathematics teaching at the “Santa Mariana de Jesús” Educational Unit during the 2025–2026 academic year. The objective of this research was to apply the Singapore Method in the planning and development of a mathematics class with second-grade students of General Basic Education. The study was conducted using a qualitative approach and employed the following research methods: descriptive and inductive methods. In addition, an interview was conducted with the teacher using an interview guide as the research instrument. Information about the practical class using the Singapore Method was also collected through observation, supported by an observation guide. Finally, a questionnaire was administered to assess students’ learning. The results showed significant improvements in students’ motivation, participation, and performance. The students were able to relate visual representations to abstract concepts and demonstrated progress in problem-solving. It is concluded that the Singapore Method is a relevant pedagogical strategy for strengthening mathematical skills from an early age, promoting meaningful learning and contributing to improving the quality of education in mathematics. However, it is necessary to provide teachers with training in the use of this method in order to achieve better results
