Abstract: La presente investigación se realizó con el objetivo de evaluar el efecto del uso de diferentes dosis de un bioestimulante a base de extracto de algas marinas (Ascophyllum nodosum) sobre el crecimiento de plántulas de café (Coffea arabica) cv. Cuscatleco, en vivero bajo condiciones de La Molina, Perú. Se utilizó el diseño completamente al azar con cuatro tratamientos y 26 repeticiones. Siendo los tratamientos los siguientes: T1: control, T2: plantas con Algax 5 ml/l, T3: plantas con Algax 7.5 ml/l y T4: plantas con Algax 10 ml/l. Se realizaron cuatro aplicaciones del extracto con un intervalo de 15 días. Se evaluaron los siguientes parámetros: altura, diámetro, longitud de raíz, número de hojas, peso seco (hojas, tallo, raíces), relación peso seco parte aérea/raíz (A/R), índice de robustez (IR), índice de calidad de Dickson, y porcentaje de nitrógeno, fósforo y potasio total. El efecto del uso de las diferentes dosis de Ascophyllum nodosum se hicieron evidentes sobre el crecimiento del café cv. Cuscatleco en condiciones de vivero. Para el caso de los parámetros: altura de planta, longitud de raíz, peso seco de hojas y tallos, relación peso seco parte aérea/raíz y porcentaje de fósforo, se encontraron diferencias estadísticas significativas en el tratamiento con dosis de 10 ml/l de Algax (T4). Mientras que para los parámetros: diámetro de tallo, número de hojas, peso seco de raíces, índice de robustez, índice de calidad de Dickson y porcentaje de nitrógeno y potasio, no se encontraron diferencias estadísticas significativas entre los tratamientos. Sin embargo, se observó una tendencia al aumento de todos los valores de los parámetros evaluados a medida que se incrementaron las dosis de Ascophyllum nodosum.
The present research was carried out to evaluate the effect of using different doses of a biostimulant based on seaweed extract (Ascophyllum nodosum) on the growth of coffee seedlings (Coffea arabica) cv. Cuscatleco, in nursery conditions in La Molina, Peru. A completely randomized design with four treatments and 26 replications was used. The treatments were as follows: T1: control, T2: plants with Algax 5 ml/l, T3: plants with Algax 7.5 ml/l and T4: plants with Algax 10 ml/l. Four applications of the extract were made at an interval of 15 days. The following parameters were evaluated: height, diameter, root length, number of leaves, dry weight (leaves, stem, roots), aerial part/root dry weight ratio (A/R), hardiness index (IR), Dickson's quality index, and percentage of nitrogen, phosphorus and total potassium. The effect of the use of different doses of Ascophyllum nodosum was evident on the growth of coffee cv. Cuscatleco under nursery conditions. For the parameters: plant height, root length, dry weight of leaves and stems, dry weight ratio of aerial part/root, and percentage of phosphorus, significant statistical differences were found in the treatment with a dose of 10 ml/l of Algax (T4). While for the parameters: stem diameter, number of leaves, root dry weight, robustness index, Dickson's quality index, and percentage of nitrogen and potassium, no significant statistical differences were found between treatments. However, there was a tendency for all the values of the parameters evaluated to increase as the doses of Ascophyllum nodosum were increased.
