Soil moisture content and maize grain yield under conventional and conservation agriculture practices - results of short term field tests in liselo, Namibia

Christian Thierfelder (2023, [Artículo])

This article focuses on the results from trials developed to monitor the short-term effects of conventionally tilled systems versus CA on soil quality and crop productivity under conditions of the major cropping systems in central, north-central and north-eastern regions of Namibia. Conventional tillage (CT), Minimum tillage (MT), Minimum tillage, mulch (MT-M), Minimum tillage, rotation (MT-R) and Minimum tillage, mulch and rotation (MT-MR) were the primary treatments tested. Significant differences (p≤0.000) among the treatments were observed in the 0-60 cm soil profiles where MT-M plots had the highest soil moisture content (39.8 mm, Standard Error of Mean 0.2815) over the study period. A significant difference (p=0.0206) in grain yield was observed in the second season with CT plots yielding the highest grain yield (3852.3 kg ha-1, standard error of mean 240.35). Results suggest that CA has the potential to increase water conservation and contribute to reduction of the risk of crop failure. Climate change driven degradation under conventional tillage necessitate alternative sustainable tillage methods. Conservation tillage methods and conservation agricultural practices that minimize soil disturbance while maintaining soil cover need to be adopted more locally as viable alternatives to conventional tillage.

On-farm assessment of yield and quality traits in durum wheat

Facundo Tabbita Iván Ortíz-Monasterios Francisco Javier Pinera-Chavez Maria Itria Ibba Carlos Guzman (2023, [Artículo])

BACKGROUND: Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted to increase. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. Developing a novel cultivar takes, on average, 10 years and advanced lines are tested during the process, in general, under standardized conditions. Although evaluating candidate genotypes for commercial release under different on-farm conditions is a strategy that is strongly recommended, its application for durum wheat and particularly for quality traits has been limited. This study evaluated the grain yield and quality performance of eight different genotypes across five contrasting farmers’ fields over two seasons. Combining different analysis strategies, the most outstanding and stable genotypes were identified. RESULTS: The analyses revealed that some traits were mainly explained by the genotype effect (thousand kernel weight, flour sodium dodecyl sulfate sedimentation volume, and flour yellowness), others by the management practices (yield and grain protein content), and others (test weight) by the year effect. In general, yield showed the highest range of variation across genotypes, management practices, and years and test weight the narrowest range. Flour yellowness was the most stable trait across management conditions, while yield-related traits were the most unstable. We also determined the most representative and discriminative field conditions, which is a beneficial strategy when breeders are constrained in their ability to develop multi-environment experiments. CONCLUSIONS: We concluded that assessing genotypes in different farming systems is a valid and complementary strategy for on-station trials for determining the performance of future commercial cultivars in heterogeneous environments to improve the breeding process and resources.

Pertinencia cultural del enfoque de graduación en mujeres en extrema pobreza en México 2019-2021

Benito Salvatierra Laura Itzel Ramírez Ramos Austreberta Nazar_Beutelspacher BARBARA CAROLINA LINARES BRAVO (2023, [Libro])

La presente obra expone los resultados de la evaluación de cinco indicadores de pertinencia cultural (expectativas, experiencias, estrategias, valores y decisiones) del proyecto “Empoderamiento de Mujeres y Jóvenes a través del Enfoque de Graduación en Inclusión Financiera en México”, instrumentado en Chiapas y Yucatán por la ONG internacional Trickle Up con el apoyo de cuatro organizaciones sociales locales. Este libro cobra relevancia en un contexto hasta este momento, caracterizado por 50 años de trayectoria de políticas públicas y programas sociales que no han logrado disminuir las desigualdades sociales y económicas que afectan principalmente a la población rural e indígena del país, por lo que pone en manos del lector un marco teórico conceptual, metodológico y de postulados sobre la importancia de la pertinencia cultural y la necesidad de integrarla a los proyectos y programas, ya sean de carácter público, social o privada, como una forma de garantizar su apropiación y continuidad por la población local. En ese sentido, el Enfoque de Graduación se presenta como una alternativa viable y factible para combatir la pobreza general y pobreza extrema, en la medida en que su diseño, como la instrumentación de cada uno de sus componentes (focalización, alfabetización financiera, acompañamiento, capacitación, transferencia de activos, protección social y apoyo al consumo) se realice tomando en cuenta las buenas prácticas, los aprendizajes y desde luego, considere reajustes que atiendan las barreras y recomendaciones derivadas de esta evaluación integral. Finalmente, podrán encontrar de forma detallada el proceso de construcción de variables e indicadores, la metodología (cuantitativa y cualitativa) utilizada por el equipo evaluador de ECOSUR, por lo que este libro puede ser una referencia metodológica y estadística para futuras evaluaciones de proyectos que buscan una incidencia socioeconómica en el bienestar de la población.
