“…The precipitation is also a limiting factor for stevia and according to Lavini et al (2008) precipitation below 200 mm impairs productivity, directly affecting the production of stevia biomass. In spite of this, dry leaf yield of accessions 4, 9 and 12 were higher than those found by Andolfi et al (2006), Fronza and Folegatti (2003), González et al (2007), Lima Filho et al (2004), Megeji et al (2005), Pal et al (2013Pal et al ( , 2015, and Serfaty et al (2013). For the first year of cultivation whose values ranged between 1.6 and 4.4 t ha -1 .…”

Stevia, a native species of South America, is commercially important as a source of the non-caloric diterpene glycosides stevioside and rebaudioside-A. Although it has been cultivated in southern Brazil, the production is not enough to meet the domestic market demand. This study evaluated biomass accumulation, morphological and physiological characters, and steviol glycosides yield of seven stevia accessions after two cuts. A great variation for the different plant characteristics was found between the first and second cuts. There was a positive correlation between biomass production and SGs content and productivity. The overall Principal Components Analysis results in both cuts indicate that the accessions CE7 and CE14 presented great Reb-A yield, height and lodging (%). The accessions CE4 and CE12 produced high Ste yield and accessions CE6, CE8 and CE9 the highest leaf:stem ratio and low SGs. The stevia accessions showed characteristics of the interest for crop improvement for both biomass and SGs production.

“…En cuanto a la concentración de esteviósidos las mayores concentraciones se evidenciaron en el muestreo 1 y con un PMS de 30-40 cb, con 2,6% y las menores en el muestreo 2 con 1,3%; presentándose diferencias estadísticas significativas entre muestreos mas no entre tratamientos. Concentraciones diferentes de edulcorantes en hoja reportan Fronza y Folegatti (2003), quienes obtuvieron un máximo de 6,49% de esteviósidos para un cultivo de estevia de 8 meses de trasplantado, momento en el que el 10% del cultivo se encontraba en floración y la concentración del edulcorante eran las más altas. Así mismo, reportan similitud entre la concentración de esteviósidos en estevia Sakaguchi y Kan (1982) quienes determinaron entre un 5% y 15%.…”

Foto: J.A. Niño RESUMENEn los últimos años la biotecnología ha introducido en el mercado mundial los edulcorantes artificiales bajos en calorías a base de componentes químicos, los cuales surgieron para satisfacer las necesidades de personas con limitaciones respecto al consumo de azúcar y calorías en su dieta. Entre otras especies, la estevia es una planta de la que se obtienen edulcorantes como esteviósidos y rebaudiósidos, pero su cultivo en Colombia se encuentra técnicamente rezagado, particularmente en el manejo del riego. Se estudió el potencial mátrico del suelo (PMS) en un cultivo de estevia, variedad Morita II, en el municipio de Prado, Sur del departamento del Tolima, Colombia, mediante la instalación de baterías de tensiómetros y la aplicación de diferentes láminas de agua con el fin de determinar el rango de PMS (0-5 cb, 10-20 cb, 30-40 cb, o 50-60 cb). Se pudo determinar qué niveles de riego superiores a los 5,4 mm diarios no redundan en el aumento del índice de cosecha y en la concentración de edulcorantes para el cultivo de estevia, que un PMS ≤20 cb contribuye hasta en un 1% en el aumento de la concentración de esteviosidos y en 0,5% en el aumento de la concentración de rebaudiósidos, y hasta en un 5% en el aumento del índice de cosecha en relación a PMS superiores. Tensiones entre 50 y 60 cb pueden ser un buen indicador en la eficiencia hídrica de la planta y del riego por goteo, para emisores colocados a 20 cm del cuello de raíz de la planta en sistemas de cultivo de estevia bajo las condiciones agroecológicas de este experimento. Palabras clave adicionales:estrés hídrico, tensión, evapotranspiración, edulcorantes, índice de cosecha, uso eficiente del agua. ABSTRACTIn recent years, biotechnology has introduced low-calorie, chemical-based artificial sweeteners to the global market in response to the needs of people with limitations regarding the consumption of sugar and calories in their diet. Among other species, stevia is a plant from which sweeteners such as stevioside and rebaudioside are derived, but its cultivation in Colombia is technically lagging, particularly in regards to irrigation management. We studied the soil matric potential (SMP) in stevia cultivation, Morita II variety, grown in the municipality of Prado, in the southern province of Tolima, Colombia, using tensiometer battery installations and the application of various water levels in order to determine the SMP range (0-5 cb, 10-20 cb 30-40 cb, or 50-60 cb). It was found that the irrigation levels of more than 5.4 mm per day did not result in an increased harvest index or concentration of sweeteners for the stevia culture. A soil matric potential of ≤20 cb resulted in an increase of up to 1% in the concentration of the steviosides and an increase of up to 0.5% in concentration of the rebaudiosides;...

“…Since the market price was 0.1 RMB m -3 , this implies that the water consumption was more than 1000 m 3 year -1 in a 1 mu field. Stevia crop evapotranspiration for the total cycle (80 days) was estimated through a microlysimeter by Fronza and Folegatti (2003) and was found to be 464 mm. Thus, in a 1 mu field, the mean water demand for cultivating stevia is calculated to be 309.5 m 3 , meaning the current irrigation may be 690.5 m 3 more than demand.…”

Abstract:Proper management of irrigation and fertilizer for different crops is beneficial to the sustainable development of agriculture. Zhangye Oasis, which is an arid region surrounded by water dependent agricultural areas with canal-type irrigation systems, has been utilising the majority portion of the discharge of Heihe River. Maize is the dominant cash crop, while the cultivation of a new cash crop, stevia, has also been under expansion in recent years. This study was conducted with both a social survey approach and science experiment approach, aiming to comprehensively understand the management of irrigation, fertilizer and soil data, simultaneously. The water consumption, fertilizer application and soil condition of stevia and maize fields in Linze County were investigated and compared. The social survey on the perception of farmers revealed that the cultivation of stevia, which had greater cash ability, required less fertilizer than maize cultivation, while water consumption showed little difference. The nitrate and ammonium contents of stevia fields were higher than those of maize fields, indicating that stevia fields could be cultivated with less chemical fertilizer. The result that the nitrate contents in the middle and lower soil samples were higher than those in upper soil samples, suggests nitrate leaching. According to the results, it is suggested that less chemical fertilizer can be applied and less water used for irrigation in stevia fields of the Zhangye Oasis, and there is therefore a good opportunity for adopting stevia as a new type of cash crop for sustainable agriculture, with improved management of irrigation and fertilizer usage.

Water consumption of the estevia (Stevia rebaudiana (Bert.) Bertoni) crop estimated through microlysimeter

Abstract: The knowledge of water requirement of crops in the different growing phases elicits higher crop yield and rational use of water resource. The aim of this work was to estimate the water consumption of stevia using two constant watertable microlysimeters.
