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.

Keywords: F6 lines, rice, crosses, morphological characteristics, agronomic and physiological.

Holguín-Flores Edisson Andrés, Santacruz-Terán Stalin Gustavo — Wed, 09 Jul 2025 00:00:00 +0000

Coffee is one of the world's most valuable commodities. 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.

Wed, 09 Jul 2025 00:00:00 +0000

The study analyzes the physical and chemical characteristics of the soil in a protective forest and a rotation crop (corn), with the aim of evaluating their impact on soil quality and sustainability. 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.

Family health is essential because it promotes the physical and mental well-being of all its members. 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.

Multitemporal analysis of the cultivated areas of Theobroma cacao L., in the parish Eloy Alfaro of the Chone canton

Wed, 09 Jul 2025 00:00:00 +0000

The expansion of cocoa cultivation in the Eloy Alfaro parish of the Chone canton and its impact on natural vegetation cover has been the subject of study. 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.

Effect of soaking and heat treatments on the physical, chemical and functional characteristics of Vigna unguiculata and Lupinus mutabilis sweet

Wed, 09 Jul 2025 00:00:00 +0000

The increase in population requires greater food production. 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.

Keywords: cooking, high pressure cooking, absorption, emulsion, foaming estability.
