Efecto de la aplicación de fibra de coco (Cocos nucifera L.) en el almacenamiento y eficiencia del uso del agua en un Alfisol, sembrado con ballica (Lolium multiflorum L.) y en la toxicidad en lechuga (Lactuca sativa L.).Effect of applying coconut fiber (Cocos nucifera L.) on storage and water use efficiency in an Alfisol seeded with ryegrass (Lolium multiflorum L.) and its toxicity in lettuce (Lactuca sativa L.).The search for techniques that allow a more efficient use of water is a global task, since this resource is increasingly scarce and its quality is constantly deteriorating. The objective of this study was to determine the effect of applying coconut fiber CF on physical-hydric parameters of the soil and its water use efficiency (WUE). The effects of coconut fiber (CF) were assessed on water consumption, water use efficiency and aerial and root biomass of Italian ryegrass (Lolium multiflorum L.). In addition, it was also evaluated whether CF causes toxic effects on lettuce seeds (Lactuca sativa L.). Treatments were established according to the proportion of CF and soil in g g -1 soil CF: T1 = 1:80, T2 = 1:40 and T3 = 1:20, and a control treatment (T0 = no substrate). Additionally, 3 charges of water (100, 75, 50 % of field capacity) were established. Results showed that the best treatment for water consumption was T3-50 (377.8 ml), for WUE the best treatment was T3-100 (8.52 kg DM m -3 ), for aerial biomass it was T3-100 (4.59 g MS) and in the case of root biomass the best treatment was T3-100 (1.92 g MS). It was concluded that the additionof coconut fiber substrate to the mix improves the physical and hydrological characteristics of degraded soil. There were no toxic effects on lettuce among the applied rates of CF. The germination index (IG) ranged from 124.82 to 156.03 % and the best treatments were T3 and T2.
El tercer volumen de la serie, "Guía Esencial de Medicina Interna en el Primer Nivel de Atención Tomo 3", continúa su misión de brindar información esencial y de calidad a los profesionales de la salud que trabajan en el primer nivel de atención médica. Escrito por un equipo de expertos en el campo, este tomo aborda una gama diversa de temas que se encuentran frecuentemente en el primer nivel de atención, como las enfermedades cardiovasculares, las infecciones respiratorias, la diabetes, los trastornos de salud mental y las enfermedades crónicas degenerativas. También se hace un énfasis particular en las consideraciones de atención médica en poblaciones específicas, como los niños, los ancianos y las mujeres embarazadas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
