Studies regarding Ocotea caudata’s phytochemical and pharmacognostic uses are scarce, thus, this work is the first to study its fruits. O. caudata (Nees) Mez fruits from Colombia were investigated for their oil content. Heptane extraction from O. caudata fruit oil yielded 54.9 % of total lipids, where the fatty acid composition was determined. The oil analysis by gas chromatography with flame ionization detection (GC-FID) demonstrated that lauric acid was the most abundant fatty acid (51.7 %, C12:0). In addition to lauric acid, oleic acid (23.6 %, C18:1) and palmitic acid (16.6 %, C16:0) were found. The fatty acid composition was confirmed by gas chromatography-mass spectrometry (GC-MS). O. caudata can be considered as a species that accumulates medium-chain saturated fatty acids (C12) and long-chain unsaturated fatty acids (C18). In conclusion, many of its health benefits may be due to its high content of lauric acid. Therefore, this oil is highly regarded for its nutritional and health properties.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135314510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Watson y la sincronización de nutrientes de cuatro dietas para cabras criollas. Se utilizó un modelo de mediciones repetidas que evaluó las variables de producción de leche, consumo de alimento y conversión alimenticia. Se utilizaron tres cabras criollas por tratamiento para evaluar las diferencias entre las dietas. Las cabras fueron alimentadas durante un periodo de 3 meses en el que se ofreció consumo controlado de las dietas. De acuerdo con los resultados observados, los tratamientos no mostraron diferencias estadísticas significativas (p>0.05) en las tres variables valoradas. Las cabras en el tratamiento ASINC con ORE (T1) lograron una tendencia de mayor consumo de alimento en comparación con los otros tratamientos. Con respecto a la producción de leche, se observó una variación entre los tratamientos, donde ASINC sin ORE (T2) mostró mayor producción en el mes 1, ASINC con ORE (T1) en el mes 2 y ASINC con ORE (T4) en el último mes de prueba. La producción de leche varió entre 0.543 kg/día y 1.027 kg/día. El consumo de alimento fluctuó entre 0.821 kg/día y 1.588 kg/día mientras que el rechazo de alimento fue de 0.036 kg/día a 0.259 kg/día. Los resultados sugieren que la inclusión de Lippia palmeri S. Watson en la dieta de cabras en lactación no causa cambios en las variables estudiadas, sin embargo, se puede utilizar como un aditivo natural, para apoyar la producción en temporada de escasez de alimento en el agostadero de regiones áridas y semiáridas.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136364629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para reducir la absorción de Cd del suelo, se evaluaron los efectos de la omisión de macronutrientes sobre la absorción de Cd por plantas de arroz en seis suelos tropicales del Ecuador; para ello, se realizó un ensayo en condiciones de invernadero, donde se evaluaron nueve tratamientos: testigo 1 (sin fertilización y sin Cd), un testigo 2 (sin fertilización con Cd), fertilización completa (N, P, K, S, Mg, Ca) y los seis tratamientos restantes de omisión de un nutriente a la vez, usando un diseño de experimentos de bloques completos al azar, con parcelas divididas, lo cual fue replicado tres veces. Las variables evaluadas fueron comparadas empleando las pruebas de Tukey y Bonferroni con un valor de P<0.05. Los resultados encontrados muestran que la fertilización completa estimula la absorción de Cd en los suelos de las seis provincias evaluadas (Esmeraldas, Manabí, Guayas, El Oro, Los Ríos y Sucumbíos); además, las omisiones de los nutrientes afectaron la absorción del Cd, variando independientemente de las características del suelo, por lo que se considera esta técnica como una alternativa válida para evaluar la absorción de Cd bajo diferentes condiciones edafoclimáticas y garantizar la inocuidad del producto que va a ser consumido por la población.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"376 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136364800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El presente estudio evaluó el efecto del monocultivo de papa (Solanum tuberosum L.) sobre la calidad edáfica en el Páramo de Guerrero. Para ello se comparó un conjunto total de datos (CTD) de 14 variables edáficas en tres agroecosistemas: (1) monocultivo convencional de papa (SC), (2) suelo en descanso (SD) y (3) un bosque (BO). Posteriormente, a partir del CTD se seleccionó un conjunto mínimo de datos (CMD) de 11 indicadores fisicoquímicos y microbiológicos empleados en la determinación del índice de calidad de suelos (ICS). Los mayores valores del ICS se obtuvieron en el BO (1.11) y SD (1.10), seguido del SC (1.07). Los resultados evidencian que las prácticas agrícolas implementadas en el páramo han afectado la calidad edáfica, lo cual es atribuido principalmente a menores contenidos de carbono (C) orgánico, humedad y actividad enzimática (catalasa) en el SC. Así mismo, a través de la guía diagnóstica en campo, se evidenciaron alteraciones en indicadores físicos como la resistencia al rompimiento, presencia de capas endurecidas y disminución en la velocidad de infiltración.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136364807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental unit was set up in the rural area of Ouro Verde, municipality of São Domingos, state of Bahia, Brazil. Five treatments were tested by diluting wastewater and supply in the percentages 0 %, 25 %, 50 %, 75 %, and 100 %. Soil samples were taken at depths of 0 - 35 cm (P1), and 35 - 70 cm (P2) from the sampling units with cultivar, control units without cultivar, and the unit without treatment (white). The cultivar was of corn (Zea mays L.), of the family Poaceae, which has a relatively short cycle (60 - 120 days). At the end of the experiments, after the harvest, the control units presented average Ca, P, K, and OM percentages from 5% to 66 % higher than white, while in the sample units, the percentages were 4% to 44 % higher, due to consumption by the cultivar. The contribution of TKN in the sampling units was the minimum sufficient for consumption by the cultivar. Compared to the control units, the sampling units presented Na, SAR, PST, and EC percentages higher by 35 - 113 % in P1, and by 29 – 456 % in P2, which indicates a higher consumption of cation by the cultivar in P2; change of ion distribution in the soil cation exchange site; as well as predisposition of the soil to sodification (increase of PST) and salinization (increase of EC). Consequently, the application of treated domestic effluents for agricultural activity, although it adds nutrients to the soil, has negative effects due to the increase in soil sodicity and salinity.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136364802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although jambu is widely cultivated, agronomic information about its management remains scarce. The aim of the current study was to analyze the physiological potential of jambu seeds stored in different packages and environments. The investigated packages comprised glass, Eppendorf tubes, plastic bags and paper bags conditioned in refrigerator and under natural conditions in Castanhal, Pará, for 360 days. Seed germination, first germination count, emergence seedlings, germination and emergence speed index, and seedling dry weight and length were the variables evaluated at 40-day intervals. The experimental design was completely randomized, with four replicates of 50 seeds per treatment. Jambu seeds were only influenced by the environment where they were stored; the ones stored under natural conditions recorded decreasing behavior for the investigated variables until they reached zero, after 280 storage days. It was possible to conclude that the physiological potential of jambu seeds stored in refrigerator was better conserved.","PeriodicalId":476429,"journal":{"name":"Acta Agronómica","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136364493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
