Evaluación de la eficiencia de la fertilización orgánica mineraly química en el cultivo de fresa (fragaria x ananassa duch) cv Sabrina en la vereda San José, Municipio de Mutiscua Norte de Santander.

Abstract

At the municipality of Mutiscua, strawberry cultivation is an important line in agriculture and for the local economy being an alternative of income generation to the region. To meet the nutritional needs of plant cultivation and indiscriminate use of fertilizers is used action that causes environmental damage such as land damage, water and air pollution, as well as being harmful to human health. Therefore, the objective of this work was to evaluate the efficiency of organic mineral fertilization (compound fertilizer) compared to chemical fertilization on the different variables that determine the yield of the strawberry plant (Fragara x ananassa Duch) cv Sabrina in the municipality of Mutiscua, North of Santander. For this, a randomized design of completely randomized blocks was carried out with five treatments: T0: control without fertilization, T1: organic mineral fertilizer (100% of the required dose), T2 chemical fertilization (100% of the required dose), T3 : organic mineral fertilizer (50% of the required dose) + chemical fertilizer (50% of the required dose), T4: organic mineral fertilizer (80% of the required dose) + chemical fertilizer (40% of the required dose) and four repetitions in which the number of leaves of the plant was evaluated at 30, 45, 60, 75 days after sowing, the height of the plant, leaf area of the plant, length of leaflets, width of leaflets, length by width of leaflets, silhouette, number of floral organs, number of flowers, number of fruits, flowering plants, days of flowering. According to the results in T1, it obtained outstanding results in the variables of number of leaves, height, leaf area, length of leaflets, width of leaflets, length by width of leaflets and silhouette. Although for the variables of number of floral organs, number of flowers, number of fruits, flowering plants there were no significant differences, T1 was the one that obtained the best results. The application of organic mineral fertilizers obtained superior results compared to chemical fertilization, being an economically feasible and environmentally friendly alternative.
