Índica and japónica), under the climatic conditions of the Manglaralto parish, Santa Elena province https://publicacionescd.uleam.edu.ec/index.php/allpa/article/view/1571 <p>The experiment was conducted at the Manglaralto Support Center, Santa Elena Province. The objective of this research was to evaluate the development of 21 F6 rice lines (Oryza sativa sp. indica and japonica) adapted to the climatic conditions of the area. Morphological and productive characteristics were analyzed using variables such as plant weight, number of tillers and panicles, panicle length, grain dimensions with and without husk, and weight of 1,000 grains. A Completely Randomized Block Design was used with 21 treatments and 3 replications. For the analysis of agronomic variables, InfoStat software was applied, comparing treatment means through analysis of variance (ANOVA) with Tukey’s test (≤ 0.05) to compare means. The results showed that six lines stood out for their high agronomic performance, exhibiting excellent morphological and physiological characteristics under Manglaralto’s conditions. This suggests that these lines could be key to enhancing rice production in the area.</p> <p><strong>Keywords: </strong>F6 lines, rice, crosses, morphological characteristics, agronomic and physiological.</p> Yagual-De La Cruz Rocío Maribel, León-Mejía Ángel Rodolfo, Ramírez Flores Lenni Crisol, Arzube-Mayorga Mercedes Pola Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

Its manufacturing process generates waste that could be transformed into a product. The purpose of this study was to obtain a paper with characteristics similar to commercial paper. To this end, the use of sodium hydroxide at three concentrations (13, 15, and 17%) and the type of starch used in the sizing phase (cassava starch and corn starch) were studied on the paper's physical and mechanical characteristics. The paper with the best characteristics was obtained with cassava starch as a sizing additive. Regarding thickness, treatments T2, T3, T5, T6, T8, and T9 ranged in thickness from 0.76 to 0.83 mm, complying with TAPPI Standard T 410. In the case of ash analysis, treatment T4 showed the lowest ash content (4.12%). The weight treatments exceeded the requirements of TAPPI T410 (70-119 g/m2), but are nevertheless suitable for paperboard and cardboard. The evaluation of the whiteness index showed that the concentration of NaOH influences its hue. It is concluded that coffee grounds are an alternative for papermaking, and it is suggested that this line of research be continued using other starch sources, concentrations, and coffee varieties.</p> <p><strong>Keywords: </strong>By-product, revaluation, concentration, coffee bagasse.</p> Holguín-Flores Edisson Andrés, Santacruz-Terán Stalin Gustavo Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

It was carried out at the Center for Agricultural Research, Innovation and Development (CIIDEA) of the Escuela Superior Politécnica Agropecuaria de Manabí "Manuel Félix López" (ESPAM MFL), in the Bolívar canton, Ecuador. The methodology included the analysis of 120 soil samples at different depths (0-5, 5-10, 10-20 and 20-30 cm). Variables such as humidity, apparent density, real density, pH, electrical conductivity, organic matter content and soil texture were evaluated. The results showed that humidity did not vary significantly between both systems, indicating that plant cover does not always guarantee greater moisture retention. The bulk density of the protective forest showed differences between under plants and streets, with values of 1.35 g/cm³ and 1.39 g/cm³, reflecting compaction. In the rotation crop, the bulk density remained the same, with an average of 1.38 g/cm³. The comparison between texture and organic matter showed greater variability in the protective forest, with clayey to sandy textures and an organic matter content between 0.27% and 2.04%. In conclusion, the rotation crop presented a better organic matter content, suggesting that sustainable agricultural practices can improve soil structure. Also reducing compaction and increasing organic matter is the key to soil conservation and adaptation to environmental changes.</p> <p><strong>Keywords: </strong>Soil quality, Crop rotation, Protective Forest, Agricultural management.</p> Leal-Cevallos Carlos Orley, Carbo-Ibarra Jonathan Vidal, Valarezo-Beltrón Carlos Oswaldo, Reyna-Bowen José Lizardo Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

Objective: To analyze the role of family medicinal gardens in the empowerment of rural women and their impact on family health care in the Boca de Caña community. Materials and Methods: A qualitative study was conducted with 10 rural women who cultivate medicinal gardens. Semi-structured interviews and participant observation were conducted to explore their knowledge about medicinal plants, cultivation practices, uses in family health care, and perception of empowerment. Results: The women demonstrated extensive knowledge about the properties and uses of various medicinal plants (chamomile, marigold, oregano) to treat common ailments (colds, diarrhea, headaches) in their families. The cultivation of these plants gave them autonomy in health care, reducing dependence on expensive medications and promoting self-management of health. The women expressed feeling empowered by providing their families with natural remedies and preserving ancestral knowledge. Discussion: Family medicinal gardens are configured as spaces of female empowerment, strengthening the role of women as health caretakers and promoters of traditional knowledge. Access to medicinal plants improves family health and reduces vulnerability in contexts of limited access to health services. Conclusion: Family medicinal gardens empower rural women, giving them autonomy in family health care and strengthening their role as transmitters of ancestral knowledge.</p> <p><strong>Keywords: </strong>medicinal plants, self-care, empowerment.</p> Peraza-De Aparicio Cruz Xiomara, Triviño-Suárez Paola Lorena, Alvarado-Andrade Diego Humberto Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

Using Sentinel-2 and Landsat 7 satellite images, supervised and unsupervised classification techniques were applied to identify cultivated areas and their temporal evolution. Supervised classification allowed for a more accurate characterization of the crops. In addition, the analysis of vegetation indices showed that NDVI is a robust indicator for assessing the health of cocoa crops, presenting a high correlation with other spectral indices. However, the expansion of cultivation has resulted in a reduction in natural vegetation. The findings highlight the need to implement sustainable agricultural practices, such as agroforestry systems and efficient soil management, to balance cocoa production with environmental conservation.</p> <p><strong>Keywords: </strong>Cocoa, remote sensing, spectral indices, classification, sustainability.</p> Burgos-García Dioclesiana María, Delgado-Alcívar Roger Adrián, Reyna-Bowen Lizardo Mauricio, Cedeño-García George Alexander Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

However, the production of proteins of animal origin requires the use of more resources in relation to vegetable proteins. Cereals and legumes are sources of protein for human nutrition, which could partially replace proteins of animal origin. Native crops of cereals and legumes also allow us to strengthen the food security of the regions from which they come, such as lupine (Lupinus mutabilis sweet) and canario beans (Vigna unguiculata). In the present study, the effect of soaking and thermal treatment (cooking and high-pressure cooking) on the physical, chemical and functional characteristics of bean and lupine seeds and flours was evaluated. The results showed that the soaked grains had a greater mass and greater hydration capacity than those that were not soaked prior to heat treatment. Bean and lupine flours subjected to soaking and heat treatment showed low foaming capacity but high foaming stability. Regarding the chemical composition, only the lipid content showed dependence on the soaking-thermal treatment combination, with the lipid content being higher for the samples that were subjected to soaking.</p> <p><strong>Keywords: </strong>cooking, high pressure cooking, absorption, emulsion, foaming estability.</p> Mesías-Otero Erika Paola, Benavides-Mera Melany Selena, Santacruz-Terán Stalin Gustavo Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.

They represent great nutritional potential for current and future generations in the search for food sovereignty due to their high nutritional and culinary potential. On the Isle of Youth, very promising results have been obtained with these species regarding their propagation, diverse culinary forms, and production and obtaining a gluten-free flour. The objective was to train producers, technicians, and specialists on the potential of Artocarpus species, using best practices for their widespread use in three Cuban provinces. Participatory research and extension techniques were used as methodology. As a result, three theoretical and practical workshops were held that allowed for the socialization of the experiences gained on the Isle of Youth; producers acquired new knowledge about the culinary potential and flour production. These workshops allowed for the sharing and application of good practices learned in the propagation, culinary diversity, and production of flour in these provinces, contributing to improved human nutrition, given the importance of this fruit as a healthy, gluten-free food. It is concluded that the theoretical and practical workshops provided new knowledge and skills to producers and other participants regarding the use of good practices and the potential of these species.</p> <p><strong>Keywords: </strong>Artocarpus, good practices, diffusion, potential.</p> García-Collado Marlene, Estévez-García Ileana Hortensia, Montesinos-Álvarez Rafael Copyright (c) 2025 Revista de Ciencias Agropecuarias ALLPA.
