Evaluación de tres fertilizantes orgánicos para mejorar la producción de fresa (Fragaria x ananassa)

Abstract

Strawberry is an important crop in the Ecuadorian economy; however, several factors have been pointed out as causing losses in strawberry production, mainly related to the cultivation system, including fertilization management. The use of fertilizers in crops can generate contamination of water and soil, so it is necessary to evaluate alternative sources to provide nutrients to crops and ensure optimal levels of production. Thus, in this study the effect of three organic fertilizers (Algatec, Alg^TeqWP and SumakCrop) on the production of strawberry (Fragaria x ananassa) was evaluated. Each of the organic fertilizers was used in three doses (0.32, 0.40 and 0.48 g / L) to determine its effect on the height of plants, number of flowers, size (width and length) of the fruit and the weight of the fruit. The study was conducted in a completely randomized block experimental design with a factorial arrangement of 3 x 2 + 1, the factors being the type and doses of the product. The results showed an effect of both the type of product and the dose applied in each of the variables evaluated. The highest values were reached when Alg^TeqWP was used at a dose of 0.48 g/L, with which higher plant height, number of flowers and both fruit size and weight were observed, followed by the values observed with the use of SumakCrop. Based on the positive results obtained in the present investigation, the inclusion of the organic fertilizers Alg^TeqWP and SumakCrop in the fertilization programs of strawberry plants is suggested, however, it is recommended to carry out an economic study to evaluate the feasibility of use.
