Bioorganic Nutritional Alternatives in Carrots (Daucus carota var. sativa), under Intensive Gardening

Context: One oftoday´s challenges is to provide food to all inhabitants, taking into account the growth of global population, especially into the cities. Accordingly, the urban farming systems are important, as they offer a real solution in face of the people’s demands. Objective: To compare different bioorganic nutritional alternatives and their influence on growth and yield indicators in carrots (Daucus carota var. sativa). Methods: This research was done at Ernesto Che Guevara intensive green garden (UEB No. 2), from the Agricultural Company of Esmeralda municipality, between December 2016 and March 2017, on non-gley plastic dark soil with high fertility. A completely randomized experimental design was applied, with five treatments and three replicas, the indicators evaluated were plant height, root length, and yield. Results: The best agronomic indicators were achieved in the treatments based on fortified liquid humus enriched with boron, calcium, and zinc, which did not differ among them, but were different from the natural liquid humus, and the control. The fortified liquid humus produced the highest yields and the best economic results. Conclusions: A favorable response was observed to bioorganic alternatives in terms of plant growth and yields. The fortified liquid humus had the best economic effect, with a remarkable increase in revenues, compared to the control

Alternativas bioorgánicas de nutrición en el cultivo de la zanahoria (Daucus carota var. sativa) en un huerto intensivo

Context: One of the current challenges is to provide food to the world, taking into account that demographic growth moves to urban areas, so urban agricultural production systems are important as a real solution to population demand. Objective: to compare different bioorganic nutrition alternatives and their influence on growth and yield indicators in carrot cultivation (Daucus carota var.sativa). Methods: The research was conducted in areas of the Ernesto Che Guevara intensive orchard in the UEB # 2 belonging to the Agricultural Company of the Esmeralda municipality from December 2016 to March 2017 on a dark non-glean plastic soil of good fertility. The objective of the research was the experimental design used was completely randomized with five treatments and three repetitions, the following indicators were evaluated: plant height, root length and yield. Results: The best agronomic indicators were obtained from the treatments with fortified liquid humus, improved and the liquid humus enriched with boron, calcium and zinc, which do not differ between them, but in relation to the natural liquid humus, and the control. The fortified liquid humus achieved the best performance and the greatest economic benefits. Conclusions: There is a favorable response to the bioorganic alternatives used that are manifested in vegetative growth and yield. The fortified liquid humus was the one with the greatest economic effect with a notable increase in profit in relation to the control treatment.Contexto: Uno de los desafíos actuales es proporcionar alimento al mundo teniendo en cuenta que los crecimientos demográficos se desplazan a las áreas urbanas, por lo que los sistemas urbanos de producción agrícola son importantes como una solución real ante la demanda poblacional. Objetivo: Comparar distintas alternativas de nutrición bioorgánicas y su influencia en los indicadores de crecimiento y rendimiento en el cultivo de la zanahoria (Daucus carota var. sativa). Métodos: La investigación se realizó en áreas del huerto intensivo Ernesto Che Guevara en la UEB #2 perteneciente a la Empresa Agropecuaria del municipio Esmeralda de Diciembre 2016 a Marzo 2017 sobre un suelo oscuro plástico no gleyzado de buena fertilidad. El objetivo de la investigación fue El diseño experimental utilizado fue completamente aleatorizado con cinco tratamientos y tres repeticiones, se evaluaron los indicadores siguientes: altura de la planta, longitud de la raíz y rendimiento. Resultados: Los mejores indicadores agronómicos se obtuvieron de lostratamientos con humus líquido fortificado, mejorado y el humus líquido enriquecido con boro, calcio y zinc, los cuales no difieren entre ellos, pero sí con relación al humus líquido natural, y al testigo.El humus líquido fortificado logró el mejor rendimiento y los mayores beneficios económicos. Conclusiones: Se evidencia una respuesta favorable a las alternativas bioorgánicas de utilizadas que se manifiestan en el crecimiento vegetativo y rendimiento. El humus líquido fortificado resultó el de mayor efecto económico con un notable incremento de la ganancia con relación al testigo

Single and Multiscale Models of Process Spatial Heterogeneity

The aim of this paper was to evaluate the effect of efficient microorganisms (EM) on beans cv. Delicias Rojo 364. The study took place on La Rosa Farm, 3 km northeast of Esmeralda municipality, on a typical fersialitic brown reddish soil, between January and March, 2014. A randomized block design was made with four treatments (inoculation of the seed with foliar application every 7 days before planting; foliar application after germination; inoculation of the seeds before planting without foliar application of efficient microorganisms (EM); and a control), and four replications. The indicators evaluated were plant height, stem thickness, number of internodes, amount of pods per plant, seeds per pod, and crop yields. The best results were observed after the inoculation of the product to the seed and foliar application, with the best yields (1.82 t/ha), much better than the control (0.7 t/ha)

Con un diseño en bloques al azar con cuatro tratamientos (inoculación de la semilla antes de la siembra con aplicación foliar cada 7 días, aplicación foliar después de la germinación, inoculación de la semilla antes de la siembra sin aplicación foliar de microorganismos eficientes (ME) y un testigo) y cuatro repeticiones, se evaluaron la altura de la planta, grosor del tallo, número de entrenudos, cantidad de vainas por plantas, semilla por vainas y rendimiento agrícola. Los resultados muestran que con la inoculación del producto en la semilla y la aplicación foliar presento el mejor rendimiento (1,82 t/ha) en relación al testigo (0,7 t/ha)
