“…Starting at this stage of higher water consumption, the basil plant began to develop, increasing its fresh and dry matter percentages. During the harvest stage and at The dry matter values during the harvest stage were 73 % higher than the values reported by Bekhradi et al (2015), who found that the dry matter percentage was 11,6 % under temperate conditions when the soil was maintained at 100 % of its FC. This difference may be due to the Mediterranean climatological conditions in which that study was conducted, which differed from the tropical conditions, and the moisture retention capacity of the soils, which were lower than the capacity corresponding to the soils used in this study.…”

“…For Khalid, (2006), subjecting basil plants to water stress reduced the dry matter crop but increased the concentration of the essential oil components. Bekhradi et al (2015) found reductions of up to 40 % in dry mass in the Genovese basil crop when using water irrigation depths equivalent to 50 % of the FC of the soil. However, agronomic characteristics, such as stem length, foliage area and dry matter, did not exhibit differences for different irrigation water depths (100 %, 75 % and 50 % of the field capacity).…”

“…dat: days asfter transplantation; C.V. variation coeffi cient Source: Authors the beginning of senescence, the water consumption was 3,16 mm day -1 (63,2 mm in total), a 48,1 % reduction in water consumption compared to the previous phenological stage; in contrast, the dry matter percentage increased by 38,1 % with respect to the maturity stage. According to Bekhradi et al (2015), this lower water consumption allows for the concentration of oils and metabolites on the leaves, which are highly desired in the industry. Similar results were reported by Barroso et al (2004), who found that replacing 100 % of the water depth corresponding to the water evaporated the previous week allowed the soft basil to reduce its foliage water potential from -0,6 MPa in the maturity stage to -1,4 MPa in the senescence stage.…”

The determination of the crop coefficient (Kc) throughout the phenological stages is important for the calculation of water requirements of plants. This study determined the Kc curve for Basil (Ocimum basilicum L.) in Candelaria, Valle del Cauca, and evaluated this Kc in greenhouse conditions. Three drainage lysimeters and a portable meteorological station were used to determine the reference evapotranspiration (ETo), which were set up randomly in an experimental plot. The field capacity (FC) moisture content was determined, and the soil moisture and drainage depth were periodically monitored. Daily water balance calculations were conducted to determine the crop's water needs (ETc), and the Kc was calculated based on the quotient between ETc and ETo by performing statistical regression analysis. In the second experiment, in a completely randomized bifactorial design, four treatments were established in Cali (Valle). These treatments were amount of water necessary to maintain the soil moisture at FC and amount of water calculated with the Kc (72 % FC), both treatments with and without fertilizers application. The results showed that the Kc values for basil are: growth stage, 0,45 ± 0,02 (25 days after transplant, dat); maturity stage, 0,59 ± 0,02 (26 -50 dat); and senescence stage, 0,42 ± 0,03 (51 -71 dat). In greenhouse conditions, dry mass percentage, plant height, soil pH and electrical conductivity were similar for both water regimens. The reduction on water with Kc increased the nitrogen foliar but the water use efficient decreased.Keywords: crop coefficient, efficient water management, lysimeter, crop water needs. RESUMENLa determinación del coeficiente del cultivo (Kc) de los estados fenológicos es importante para el cálculo de los requerimientos hídricos de las plantas. Este estudio determinó la curva del Kc para la albahaca (Ocimum basilicum L.) en Candelaria, Valle del Cauca, y evaluó estos Kc en invernadero. Se ubicaron tres lisímetros de drenaje y una estación meteorológica portátil para determinar la evapotranspiración de referencia (ETo), en una parcela experimental. Se determinó la humedad as capacidad de campo (CC) y se monitorearon periódicamente tanto la humedad del suelo como el agua de drenaje. Se realizaron balances hídricos diarios para determinar las necesidades de agua del cultivo (ETc) y el Kc se calculó como el cociente entre ETc y ETo por medio de análisis de regresión. En el segundo experimento se establecieron cuatro tratamientos en un diseño completo al azar en Cali (Valle). Los tratamientos consistieron en evaluar la cantidad de agua calculada a partir de CC y a partir del Kc hallado (72 % de CC), ambos tratamientos con y sin fertilización. Los resultados mostraron que los valores de Kc para cada etapa de albahaca fueron: crecimiento, 0,45 ± 0,02 (25 días después del trasplante, ddt); madurez (0,59 ± 0,02 (26 -50 ddt) y senescencia 0,42 ± 0,03 (51 -71 ddt). En invernadero, el porcentaje de materia seca, altura de planta, pH del suelo y conductividad eléctrica fueron similare...

“…Rubin es una variedad de albahaca ópalo oscuro, siendo un cultivo que tiene hojas de color rojizo-púrpura en color y un sabor más fuerte que la albahaca dulce (Bekhradi et al, 2015). Posiblemente su altura más baja podría relacionarse con una respuesta fisiológica y bioquímica en el metabolismo primario y secundario debido a la movilización y la translocación de los nutrientes en la planta, produciendo una menor altura y dirigir la respuesta a la concentración de pigmentos (Landi et al, 2013).…”

“…Rubin is a variety of dark opal basil, being a crop that has reddish-purple leaves in color and a stronger flavor than sweet basil (Bekhradi et al, 2015). Possibly its lower height could be related to a physiological and biochemical response in the primary and secondary metabolism due to the mobilization and translocation of the nutrients in the plant, producing a lower height and directing the response to pigment concentration (Landi et al, 2013).…”

ResumenEn la última década, se han realizado numerosos esfuerzos para incrementar el contenido de compuestos fenólicos y la capacidad antioxidante de plantas que vayan directo al consumo humano, empleando para esto diversos métodos de cultivo; sin embargo, los resultados han sido discrepantes acerca de la calidad de los frutos y el rendimiento obtenido, concluyendo que el alto contenido de compuestos fenólicos y la capacidad antioxidante no ha sido garantía de alto rendimiento de los cultivos. Por lo tanto, el objetivo de este estudio fue determinar un posible aumento del contenido en compuestos fenólicos totales, capacidad antioxidante total y rendimiento de tres genotipos de albahaca (Sweet Lemon, Red Rubin y Cinnamon) producidos bajo diferentes niveles de potasio (7, 9, 11 y 13 mM). Adicionalmente, se evaluó materia seca, altura de planta y número de hojas. El trabajo se llevó a cabo en la Comarca Lagunera de Durango en el año 2014. El análisis de varianza mostró diferencias significativas (p≤ 0.001) por efecto de genotipo y nivel de potasio en casi todas las variables. Se encontró interacción en compuestos fenólicos totales, capacidad antioxidante, rendimiento y altura de la planta. También se encontró correlación (R2) (p≤ 0.05) entre el nivel de potasio y todas AbstractIn the last decade, numerous efforts have been made to increase the content of phenolic compounds and the antioxidant capacity of plants that go directly to human consumption, using for this several methods of cultivation; however, the results have been discrepant about the quality of the fruits and the yield obtained, concluding that the high content of phenolic compounds and the antioxidant capacity has not been a guarantee of high crop yields. Therefore, the objective of this study was to determine a possible increase in total phenolic compounds, total antioxidant capacity and yield of three basil genotypes (Sweet Lemon, Red Rubin and Cinnamon) produced under different levels of potassium (7,9 , 11 and 13 mM). In addition, dry matter, plant height and number of leaves were evaluated. The work was carried out in the Comarca Lagunera of Durango in the year 2014. The analysis of variance showed significant differences (p≤ 0.001) due to genotype and potassium levels in almost all variables. It was found interaction in total phenolic compounds, antioxidant capacity, yield and height of the plant. The correlation (R2) (p≤ 0.05) was also found between the potassium level and all variables. The results indicate that las variables. Los resultados indican que el control de potasio en la solución de nutrientes puede ser una opción viable para mejorar las cualidades nutracéuticas en cuanto al contenido de compuestos fenólicos totales y la capacidad antioxidante sin afectar el rendimiento de albahaca.Palabras clave: Ocimum basilicum L., antioxidants, concentración de potasio, rendimiento.

The genus Ocimum is very complicated due to the presence of huge morphological variability along with genetic diversity. Basil (Ocimum basilicum L.) has pharmacological properties to treat headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunction and potential as a therapeutic agent in treating various age‐related diseases. In this study, a total of 74 genotypes were used in 2017 and 61 genotypes were adapted. Among the 61 genotypes, 50 genotypes were sown in 2018. The present investigation composed of basil genotypes was undertaken to characterize the genotypes based on morphological and phenological features, herbs, and essential oil yield of genotypes. A wide range of variations for traits like days to first cutting (56.92–101.6 d), plant height (13.67–71.90 cm), branch number (3.28–19.43 plant−1), fresh herb yields (12.94–274.11 g plant−1), and essential oil yield (0.04–1.71%) were observed and can be useful for breeding purposes. PI 652070 and PI 296391 were found superior with the highest herbs yield as compared with other genotypes. Overall, PI 358469 and Ames 32309 genotypes exhibited the highest essential oil content. A constellation analysis was conducted to investigate the genetic diversity of basil genotypes. According to the constellation plot analysis, 46 basil genotypes and four cultivars were evaluated according to morphological, yield, and International Association for the Protection of New Plant Varieties (UPOV) properties, and most of the basil genotypes and one cultivar (Midnight) were located in the same group. As a result of the constellation plot analysis, Moonlight and Dino cultivars were located in the same group with PI 141198 (Maryland, USA) and genotypes originated from Georgia, Iran, Afghanistan, Ethiopia, and Hungary located in the same main group. Other genotypes of the same origin were found in a different main group.
