Abstract
El cultivo de pimiento morrón exótico ‘Purple Beauty’ tiene importancia económica, al ser una variedad de gran atractivo y sabor, puede marcar preferencia en consumo y es una variedad que no ha sido estudiada antes en efecto de bioestimulantes y nitrógeno en dosis regular y aumentada. De la misma forma las plantas aromáticas son importantes en agricultura al obtenerse en cortos períodos y con diversidad de fines. El estudio se realizó en condiciones de estructura protegida, y 2 experimentos: N°1 pimiento y N°2 cilantrillo y albahaca. El objetivo fue conocer los efectos de bioestimulantes y fertilización en pimientos morrón exótico, cilantrillo, y albahaca en tiestos en sistema de ambiente protegido. Con aplicaciones de bioestimulantes en 2 ppm y dosis regular y aumentada de nitrógeno por planta en 8.16 g y 11.4 para
pimiento. Dosis de nitrógeno en forma regular y aumentada de 6 g y 8.7 g para cilantrillo y 6.38 g y 9.35 g para albahaca. Suelo preparado (llamado artificial) se usó en el experimento N°1, en adición también se usó suelo de la serie San Antón en el experimento N°2. Los resultados mostraron en experimento N°1, que la combinación de N en dosis regular y sin bioestimulantes (SBN std) produjo mayor altura y número de hojas a 63 ddt. El tratamiento de extracto de algas y N en dosis aumentada (EAN aum), produjo la mayor cantidad de flores y clorofila a 28 ddt. No se detectaron diferencias significativas en grosor de fruto, longitud vertical y ecuatorial del fruto. Efectos significativos se mostraron para la talla XL (extra grande) de frutos. El tratamiento de péptidos y N en dosis aumentada (PEPN aum) mostró más número de frutos, y el tratamiento extracto de algas y N a dosis aumentada (EAN aum), mayor peso de fruto. No se encontraron diferencias significativas en peso promedio de materia seca en hoja, tallo y raíz. El tratamiento de mejor resultado en pos-cosecha fue el de extracto de algas y N dosis aumentada (EAN aum), a 48 días a 10°C, seguido del tratamiento de péptidos y N regular (PEPN std) para frutos a 38 días y 20°C. En experimento N°2, para cilantrillo, se encontraron diferencias significativas en combinación de los factores de fertilización, bioestimulante y suelo. El tratamiento que de mayor contenido de materia seca y altura de plantas fue el de péptidos y N dosis aumentada en suelo San Antón. No se encontraron diferencias significativas para clorofila. Para el contenido de NO₃⁻, en hoja y tallo el tratamiento con mayor media fue el que combinaba N a dosis aumentada con péptidos, en ambos suelos. Para los valores de K⁺ en savia en hoja y tallo, el tratamiento de mejor concentración fue el de N e dosis regular sin bioestimulante. Para albahaca, se encontraron diferencias significativas al combinar bioestimulante, N y tipo de suelo. Para el contenido de materia seca y altura de la planta, el tratamiento que obtuvo mayor peso y altura fue el de péptidos y N a dosis aumentada en suelo San Antón. Para el contenido de clorofila a 35 y 63 ddt, el mejor tratamiento fue el de N a dosis regular y suelo artificial. En contenido de NO₃⁻ en hoja y tallo el mejor resultado fue el tratamiento de N a dosis aumentada, con tendencia al aumento al combinar con suelo artificial, y para la concentración de K⁺ en savia en hoja y tallo el tratamiento que muestra mayor concentración fue el de N en dosis regular, con tendencia al aumento al combinarse
con suelo San Antón. El atributo comercial de los cultivos en experimentos 1 y 2 son importantes, ya que pueden ofrecer una mejor opción en la elegibilidad de tratamientos según la necesidad productiva al momento de obtener resultados.
The exotic pepper bell 'Purple Beauty' has economic importance, being a variety of great attractiveness and flavor, can mark preference in consumption,in addition this variety has not been studied before in effect of biostimulants and nitrogen in regular and increased doses . In the same way, aromatic plants are important in agriculture to be obtained in short periods and with different purposes. The study was conducted under conditions of protected structure, and 2 experiments: No. 1 pepper and No. 2 cilantrillo and basil. The objective was, know the effects of biostimulants and fertilization on exotic pepper bell, cilantrillo, and basil in pots in a protected environment system. With applications of bioestimulantes in 2 ppm and regular and increased dose of nitrogen per plant in 8.16 g and 11.4 for pepper. Nitrogen dose in regular and increased form of 6 g and 8.7 g for cilantrillo and 6.38 g and 9.35 g for basil. Prepared soil (called artificial) was used in Experiment No. 1, in addition soil of the San Antón series was also used in Experiment No. 2. The results showed in Experiment No. 1, that the combination of N in a regular dose and without biostimulants (SBN std) produced greater height and number of leaves at 63 ddt. The treatment of algae extract and N in increased dose (EAN aum), produced the highest amount of flowers and chlorophyll at 28 ddt. No significant differences were detected in fruit thickness, vertical and equatorial length of the fruit. Significant effects were shown for fruits XL size. The treatment of peptides and N in increased dose (PEPN aum) showed more number of fruits, and the treatment of algae extract and N at increased dose (EAN aum), greater fruit weight. No significant differences were found in average weight of dry matter in leaf, stem and root. The treatment with the best postharvest results was that of algae extract and N increased dose (EAN aum), 48 days at 10 °C, followed by the treatment of peptides and regular N (PEPN std) for fruits at 38 days and 20 °C. In Experiment No. 2, for cilantrillo, significant differences were found in combination of fertilization, biostimulant and soil factors. The treatment with highest dry matter content and plant height was that of peptides and N increased dose in San Antón soil. No significant differences were found for chlorophyll. For the NO₃⁻ content, in leaf and stem, the treatment with the highest mean was the one that combined N at an increased dose with peptides, in both soils. For the values of K⁺ in leaf and stem sap, the treatment with the best concentration, was that of a regular dose without biostimulant. For basil, significant differences were found when combining biostimulant, N and soil type. For the content of dry matter and height of the plant, the treatment that obtained greater weight and height was that of peptides and N at an increased dose in San Antón soil. For chlorophyll content at 35 and 63 ddt, the best treatment was N at a regular dose and artificial soil. In NO contenido content in leaf and stem the best result was the treatment of N at increased dose, with a tendency to increase when combined with artificial soil, and for the concentration of K⁺ in sap in leaf and stem the treatment that shows the highest concentration N was in a regular dose, with a tendency to increase when combined with San Antón soil. The commercial attribute of the crops in experiments 1 and 2 are important, since they can offer a better option in the eligibility of treatments according to the productive need at the moment of obtaining results.
