Evaluación de abonos orgánicos en la producción de cebolla puerro (Allium porrum L.)

Abstract:

The investigation work was carried out in the Querochaca Educational Experimental Farm, property of the Agronomic Engineering Faculty, of the Ambato Technical University, located in Cevallos canton, province of Tungurahua, to 2 868 m.s.n.m.; their geographical coordinates are 1 22' 03" of South latitude and 78 36' 22" of West length; in order to: to establish which of the organic manure (hen manure A1, worm humus A2, "cuy" manure A3 and manure of bovine A4), acts of better way in the production and quality in the leek onion cultivation Allium porrum L. and to determine the recommendable dose of organizational matter for the cultivation (3 D1, 4 D2, 5 D3 and 6 kg/m² D4). The treatments were 16, of combination the factors in study, more a witness, that it did not receive application from organic manures. It was applied the experimental design of complete blocks at random with factorial arrangement 4 x 4 + 1, with three repetitions. It was accomplished the analysis of agreement variance to the outlined experimental design and meaning tests of Tukey to the 5% for the sources of meaningful variation, in the variables: number of leaves by plant, length of the leaf, diameter of the pseudo stem, length of the pseudo stem, length of the plant, weight of the plant and yield. Furthermore they were effected orthogonal polynomials for the factor organic manures dose, with correlation and regression calculation. The economic analysis was effected applying the methodology of the cost benefit relationship (RBC). With the application of "cuy" manure (A3), were obtained the better results, especially in the growth and development of the plant, to be observed in the treatments that received it, pseudo stem of greater diameter (3,27 cm), as from better length (18,52 cm), consequently the plants reported greater growth in length (91,59 cm), with better weight (367,48 g), being reached the highest yields (32,29 Tm/ha). The application of the organic manures in the dose of 5 kg/m² (D3), produced the better results, improving the growth and development of the plants, especially in the diameter of the pseudo stem (3,17 cm), the growth in length of the pseudo stem (18,26 cm), length of the plant (88,11 cm), consequently the weight of the plant was increased (371,89 g). Of the economic analysis is concluded that, the treatment A3D2 ("cuy" manure, 4 kg/m²), reached the greater cost benefit relationship of 0,46, in which the obtained net benefits were 0,46 times what is invested, being the greater profitability treatment.
