The use of biostimulants in high-density olive growing: Quality and production

[EN] Due to the increase of high-density holdings, especially of olive trees, the nutritional requirements of the plants are higher per unit area, which implies that a greater contribution of fertilizers to the soil is needed. Opting for fertilizers of inorganic origin will produce an increase in the pollution of the soil. In the face of this possible soil contamination, our aim is to analyze the effect of biostimulants as an alternative to chemical fertilizers, to steadily produce and maintain high quality standards during the life of the crop. Our objective is using more environmentally friendly products in order to satisfy one of the most important demands from both consumers and the authorities. In this study, we carried out five different treatments in addition to a control treatment with a supply of NPK, from inorganic products, which are used to control fertilization with a solution obtained from seaweed extracts. These treatments were applied in two crop cycles for two of the most important varieties in the current olive tree growing scenario: Arbequina and Koroneiki. This study was developed in the farm Pozohondo, which is located in a crop zone by the Palancia river (Castellón, Valencia, Spain), in the southeast of the Iberian Peninsula, where the olive trees were established in a high-density system with a planting framework of 4 x 1.5 m. We ensured an exhaustive control of the nutritional needs of the holding by using a fertigation system. We could notice differences in the productions of each applied treatment, avoiding any possible biases through the additional control of 100 randomly selected olives from each of the samples. There is an improvement in the set of physical characteristics of the olives with the treatment that provides amino acids and extra potassium based on amni acids. We analyzed the quality of the olive oil obtained from the production of each treatment by measuring the fatty acids, tocopherols and polyphenols contents. We also carried out an organoleptic tasting analysis following the rules of the International Olive Committee (IOC). We observed an improvement with regard to the rest of treatments in the pomological parameters of the olives when applying the potassium and amino acid biostimulant, while the quality of the oils was not affected by the type of fertilization applied in each treatment.This work was funded by Project AICO/2017/047.

Conventional vs. Organic: Evaluation of Nutritional, Functional and Sensory Quality of Citrus limon

Organic farming is growing rapidly worldwide since it is perceived as more respectful of the environment than conventional farming. In this sense, organic agriculture is highly appreciated by consumers since consumers around the world believe that organic food has a higher content of beneficial compounds for health and consider it of higher quality. For that reason, the objective of this research was to evaluate the nutritional, sensorial, and functional quality of the ‘Fino 49’ lemon grafted on Citrus macrophylla in conventional and organic cultivation. Fatty acids, amino acids, total phenol, and polyphenols were quantified, antioxidant activity was measured, and sensory descriptive analysis was performed. Conventional farming led to an increase in amino acid content (641 mg L1) and an increase in polyunsaturated fatty acids (254 mg 100 g1) and monounsaturated fatty acids (37.61 mg 100 g1). On the other hand, organically produced lemon fruits had better sensory profile (highlighting overall aroma (6.5), lemon odor (6.8), sourness (5.8), floral (0.6), and fresh lemon flavor (9.8)), and lower thrombogenicity index (0.15). The type of cultivation (organic and conventional) had no influence on the antioxidant activity (~1.60, ~3.08, and ~4.16 mmol Trolox L1 for ABTS+, DPPH , and FRAP, respectively) and polyphenols content (85.51 and 86.69 conventional and organic, respectively). However, to establish the advantages and disadvantages of different types of cultivation on lemon quality more studies are needed

Nutritional diagnosis norms for three olive tree cultivars in superhigh-density orchards

The preferred olive tree cultivation strategy has evolved towards high-density cultivations to increase profitability and satisfy the global demand for olive oil. However, there is a lack of specific norms for the nutritional diagnosis of new growing systems and the varieties adapted to these systems. The objective of this study is to determine the sufficiency range and the diagnosis and recommendation integrated system and compositional nutritional diagnosis norms for Arbequina, Arbosana and Picual cultivars under superhigh-density olive tree cultivation. Leaves were sampled every fifteen days, from July to December, from high-productivity trees with production densities exceeding 8000 kg ha-1. The results show two periods of stability for the three varieties of olives: July-first two weeks of August and October-November. The three varieties showed substantial variability in their macronutrient concentrations, i.e., N, P, K, Ca and Mg, during both periods. The three aforementioned methods have improved the reliability of such diagnosis and provided concurrent diagnoses. Nevertheless, all the resulting norms need to be validated through an analysis of the results obtained in practice after their application

Odontomas were surgically removed and underwent surgical window in the area where they found the upper central incisor and then link it and take it to the orthodontic arch

Uso de tertulias dialógicas. Resultados en los exámenes de ciencia agraria

[ES] Actualmente en las asignaturas de origen agrario es totalmente necesario utilizar técnicas prácticas. Se ha comprobado a lo largo de los años que son necesarios enfoques que permitan disponer de más horas prácticas para aplicar, con más rapidez y fiabilidad, cualquier técnica agraria que estemos estudiando en las aulas, como también queda reflejado en los procesos de renovación docente de las enseñanzas universitarias, necesaria para producir el cambio educativo. Con estas tertulias se trata de continuar la construcción del conocimiento a partir del diálogo que inició el autor al escribir su obra, primero de una forma individual, para pasar después a enriquecerlo aún más a través de un diálogo colectiv, diálogo que debe facilitar un conocimiento no adquirido, a la vezque con un sistema participativo y nuevas dinámicas de grupo, conseguiremos que el alumno adquiera conocimientos y los afiance. Las tertulias fueron desarrolladas en asignaturas diferentes y aunque las tenían un claro perfil agrario y se encontraban incluidas en un mismo plan de estudios. Permitió establecer resultados diferentes dado que la temática de las asignaturas lo permitía. Las asignaturas elegidas son de diferentes cultivos, leñosos y herbáceos, así como de su manejo Todas ellas en la misma titulación y en diferentes centros. Realizando por lo tanto en distintos enfoques de alumnado y contextos muy diversos, tanto formal como no formal. Los alumnos obtuvieron mejores resultados cuando la temática era tratada mediante tertulia dialógica dado que conseguía emular las condiciones prácticas con la búsqueda de información a través de la lectura.López Cortés, I.; Salazar, D.; Velázquez-Martí, B.; Estornell Cremades, J.; Martínez-Tomé, J.

Impact of Inflammatory Response Modifiers on the Incidence of Hospital-Acquired Infections in Patients with COVID-19.

The study aim was to assess the influence of inflammatory response modifiers, including anti-interleukin-6 (IL-6) biologics and corticosteroids, on the incidence of hospital-acquired infections in patients with coronavirus disease 2019 (COVID-19). METHODS: Case-control study performed at a university hospital from February 26 to May 26, 2020. Cases were defined as patients with COVID-19 who developed hospital-acquired infections. For each case, two controls were selected among patients without infections. Cases and controls were matched obeying three criteria in a hierarchical sequence: length of hospital stay up until the first infection; comorbidity; and need for Intensive care unit (ICU) admission. Conditional logistic regression analysis was used to estimate the association of exposures with being a case. RESULTS: A total of 71 cases and 142 controls were included. Independent predictors for acquiring a hospital infection were chronic liver disease [odds ratio (OR) 16.56, 95% CI 1.87-146.5, p = 0.012], morbid obesity (OR 6.11, 95% CI 1.06-35.4, p = 0.043), current or past smoking (OR 4.15, 95% CI 1.45-11.88, p = 0.008), exposure to hydroxychloroquine (OR 0.2, 95% CI 0.041-1, p = 0.053), and invasive mechanical ventilation (OR 61.5, 95% CI 11.08-341, p ≤ 0.0001). CONCLUSIONS: Inflammatory response modifiers had no influence on acquisition of nosocomial infections in admitted patients with COVID-19. Hospital-acquired infections primarily occurred in the critically ill and invasive mechanical ventilation was the main exposure conferring risk

Differences in nutrient composition of sea fennel (Crithmum maritimum) grown in different habitats and optimally controlled growing conditions

10 páginas.- 1 figura.- 5 tablas.- referenciasCrithmum maritimum L. is an edible halophyte with large potential in human nutrition field. However, it is unclear whether its nutritional value is maintained throughout the contrasting habitats where it commonly grows (cliffs, sandy and rocky beaches) and the nutritional profile of cultivated plants still remains uncertain. In this work, we provided for the first time a comparison of the nutritional profile of C. maritimum across its different type of habitats in the south of Spain and between wild plants and plant material under optimal growing conditions. The protein, amino acids, lipids, fatty acids, minerals composition and phenolic content of plants were analysed. Plants under field conditions exhibited a nutritionally balanced composition (3.8–6.2 g protein/100 g DW, 4.9–7.5 mg lipids/g WW, 3.9–5.0 g Na/100 g DW), with high phenolic content (30.2–48.0 mg/g DW) regardless of the variability of the contrasting habitats. In contrast, under optimal conditions, C. maritimum showed a greater protein and lipid content (10.2 g/100 g DW and 9.6 mg/g WW, respectively), and lower sodium accumulation (1.2 g/100 g DW), allowing a greater consumption of this halophyte without exceeding the daily intake recommendations. Conversely, phenolics were strongly decreased in these plants (6.1 mg/g DW) likely due to the absence of stress factors. © 2021 Elsevier Inc.This work was financially supported by two grants from the Spanish Ministry of Science, Innovation and Universities (RTI2018-099260-A- I00 to J.
