    Respuesta a la aplicación de N y K en el cultivo de brócoli (Brassica oleracea), VAR. SK6-401 en la parroquia Mulaló.
    (2021-04) Aldás Arias, Edgar Patricio; Curay Quispe, Segundo
    The consumption of vegetables and especially broccoli, due to the substantial contribution of nutrients in addition to its medicinal properties, as an aid in the prevention of cancer diseases; turns this into a crop of productive and commercial interest. Therefore, its management requires modernization and innovation, to achieve profitable productivity. Therefore, soil management is the fundamental basis of the development of this crop. Macronutrients in vegetables participate in fundamental functions and processes in vegetables, which affect the development and growth of crops. Hence, this research aims to determine the response of the application of N and K in broccoli var. SK6-401 in the Mulaló parish, to identify the optimal dose of N (DON) and K (DOK), its relationship with profitability in addition to carry out the economic evaluation of the treatments. This project was developed under a quantitative approach, with a type of experimental research at an applicative level. A randomized complete block design (DBCA) with three replications and an absolute control was implemented. For this, nine treatments based on fertilization were used: N and K whose application was divided into four parts during the crop cycle. The doses of N (170 kg ha-1,340 kg ha-1 and 510 kg ha-1) and K (60 kg ha-1, 120 kg ha-1 and 180 kg ha-1), which in combination were obtained the nine treatments. The days to harvest did not show a significant difference, while the variables weight, diameter and productivity showed a significant difference (P <0.05), T5 was identified through a test of means as the treatment with the best response, average pellet weight of 668 g diameter of 20 cm. While for the variables Incidence of Alternaria and Plasmodiphora it did not show significant difference. In relation to cost-1 benefit (P <0.05), T5 exceeded the average, which for this research represents a profit of 3.5 US $ for every US $ 1 invested.

    Evaluación de la extracción de n, p y k en el cultivo de Brócoli Var. Avenger
    (2021-04) Escobar, Edgar Hernán; León Gordón, Olguer Alfredo
    The increase in the consumption of broccoli Brassica oleracea worldwide, for Ecuador in recent years represents a crop of great economic importance. The lack of studies in the country on the requirements demanded by the crop for correct fertilization significantly affects the productivity and quality of broccoli. The objective of this study was to identify the level of N, P and K extraction in the broccoli Brassica oleraca var. Avenger. It was developed in the parish of Mulaló, in the province of Cotopaxi. The research was developed in an open field crop, under a quantitative approach in a non-experimental type of research at a descriptive level. The methodology for the extraction levels and obtaining N, P and K extraction curves, a cultivation area of 2 ha was established, with a sowing density of 55,000 plants ha-1, for the analysis 12 elite plants were selected At 35, 56, 75 and 95 dat, they were sent to the laboratory for analysis, the extraction results of the main macronutrients demanded by the plant were N 348.6 kg ha-1, P 61.7 kg ha-1, and K 295.2 kg ha-1, and the mathematical models of each nutrient were determined with a confidence level for N of 0.95, P of 0.96 and K of 1.0. It is recommended to consider that at 75 dat the accumulated extraction level of 251.8 kg ha-1 of K and 213.2 kg ha-1 of N influences the formation and development of the pellet.

    Aplicación de Biol enriquecido con microorganismos eficientes para la producción limpia de brócoli (Brassica oleracea var. Italica) Híbrico Legacy
    (2014-01-27) Haro Lara, Marco Rubén Darío; Rodríguez Aguirre, Fidel
    El propósito de la investigación fue evaluar el efecto de distintas concentraciones de microorganismos eficientes capturados en diferentes condiciones ecológicas (EM recolectados en la ribera del río Culapachán, sector de Quillán a nivel de río M1, EM recolectados en el sitio de la investigación, Granja Agroecológica Pillaro M2 y EM recolectados en la zona alta con vegetación natural, caserío San Juan perteneciente a la parroquia San Miguelito M3), aplicados en tres concentraciones (2% C1, 4% C2 y 6% C3) y en mezcla con biol enriquecido aplicado en tres concentraciones (5% B1, 10% B2 y 15% B3), en la producción limpia de brócoli (Brassica oleracea var. Italica) híbrido Legacy. Los microorganismos eficientes recolectados en la zona alta con vegetación natural, caserío San Juan perteneciente a la parroquia San Miguelito (M3), produjeron los mejores resultados, tanto en el crecimiento y desarrollo de las plantas, como en la calidad de las pellas, al observarse plantas con mayor altura a los 60 días (45,17 cm) y mejor diámetro de la pella (19,77 cm). La aplicación de microorganismos eficientes en la concentración del 6% (C3), influenció favorablemente en el crecimiento y desarrollo de las plantas, al reportar los mejores resultados, con mayor crecimiento en longitud del limbo dela hoja (52,49 cm), en el diámetro de la pella (19,48 cm), como también en el peso de la pella (0,40 kg), obteniéndose consecuentemente los mejores rendimientos (16,04 t/ha).
