Evaluación de la incorporación de tres dosis de tres abonos orgánicos en el cultivo de Kai -Lan (brassica olerácea) var. alboglabra en la parroquia La Península del cantón Ambato provincia Tungurahua

Abstract

An investigation of an Evaluation of the application of three doses of three organic fertilizers in the Cultivation of Kai-lan (Brassica alboglabrá) was held in the Parroquia La Península del Cantón Ambato-Tungurahua Province, at 2550 masl with an average temperature of 16 ° C and a mean of 477 mm of annual rainfall. The General Objective was established: Evaluate the application of three doses of three organic fertilizers in the Cultivation of Kai-lan and as Specific Objectives: To carry out the taxonomic classification and morphological description of the Kai-lan (Brassica alboglabrá); Determine the best source and the best doses of fertilizers applied in the cultivation of Kai-lan in the parish of the Peninsula; Propose a basic technical sheet for the production of Kai-lan that is suitable for larger plantations and is a guide for farmers; to determine the acceptance of the Ambato population in front of a new vegetable; and, contribute to the expansion of the productive spectrum of vegetables, for the horticultural area of the parish the Peninsula. The factors under study were: Factor A: Organic Fertilizers: Chicken Manure (Al), Bovine Manure (A2) and Vermiabono (A3); and Factor B: Dose: Low (DI), Medium (D2) and High (D3). For Chicken Manure the doses were: 0.5; 1.0 and 1.5 kg / m2; for Bovine Manure: 0.4; 0.8 and 1.2 kg / m2 and for Vermiabono: 0.4; 0.6 and 1.0 kg / m2 A Random Complete Blocks Design (DBCA) was applied in a factorial arrangement of 3 x 3 + 1 with a total of 10 treatments resulting from the factorial combination plus the Control in which no applied some fertilizer with 3 repetitions. The experimental unit consisted of 0.75 m2 plots. The Analysis of Variance and the Tukey Test at 5% were carried out for the sources that presented statistical significance. The evaluated indicators were: plant height at 30 and 45 days, weight of harvested stems per plant, slenderness, yield and number of harvested plants. Kai-lan was determined to be a vegetable of the brassica genus. For all indicators studied, the Factorial ranked first compared to the Witness. Regarding the variable Plant Height at 30 days, the three sources behaved similarly to the doses; Among the treatments, the following stand out: Chicken Manure * High Dose with 15.19 cm, Bovine * High Dose with 15.07 cm, Vermiabono * Medium Dose with 17.96 and Vermiabono * Dose Height with 20.22 cm the other treatments presented lower heights. In the variable Plant Height at 45 days, in the same way for Fertilizers and Dose there is a similar behavior in all the levels of these factors, in the treatments the Control and Vermiabono * Low Dose, presenting lower values of the other treatments, Vermiabano is a stand out. * High Dose with 29.24 cm and Vermiabono * Medium Dose with 25.27 cm. In the variable Weight of harvested stems per plant, in relation to Fertilizers: Vermiabono obtained 0.053 kg / plant; Regarding the Doses: High with 0.051 and Medium with 0.0445 kg / plant occupy the first places. In the treatments, Vermiabono * High Dose stands out with 0.068 kg / plant. In the Slenderness indicator, for Fertilizers we find Vermiabono and Bovino with 0.00213 and 0.00189, kg / cm, respectively; Regarding the Doses, the three behave in a similar way, while in the treatments Vermiabono * High Dose and Vermiabono * Medium Dose stand out with 0.0023 kg /. Regarding Yield, for Fertilizers Vermiabono stands out with 1.4563 kg / m2 in relation to Dose, High and Medium Dose are located with 1.39215 and 1.09526 kg / m ", while the Low Dose occupies rank B. Among the treatments is Vermiabono * High Dose with 2.12 kg / m2 in range A, Vermiabono * Average dose with 1.4307 kg / m2 in range B, the rest of the treatments are located in lower ranks. In the variable Number of Plants harvested per plot, among Fertilizers it is ranked in second place, the Witness, all other treatments rank first with an average between 19.33 and 22.67 floors. As for Dose, all three behave in a similar way. A high percentage of the Ambato population does not know about or have consumed Kai-lan, but they would very much like to. There is a very good marketing outlook for restaurants in Chinese / Asian Food. It is recommended to fertilize kai-lan with medium and high doses of vermiabono, carry out a study detailed information on the phenological development of brassica and the technical details of the entire cultivation, as well as spreading the cultivation and uses of this vegetable.
