Description
Summary:Four castor materials were evaluated in 2009 in the middle region of Valle del Sinu, Colombia. The variables were phenological development, plant height, seed production and oil yield, in order to determine the best material for commercial purposes. All materials reported high yields of oil seeds and highlighting the commercial genotype Nordestina BRS149, 2.2 t ha-1 seed and 47% oil content. Planting distances were 1.5 x 1.5 m and 2.0 x 2.0 m, with densities of 6,666 and 3,906 plants ha-1, respectively. The plant height, seed productivity and oil yield showed significant differences for the interaction density × material; while comparing each material density, seed production only showed differences. These variables were significantly different between population densities, which shows that the higher the plant height, lower productivity. The planting distance of 2.0 x 2.0 m, provides higher productivity per plant values but seed oil yields were not different between densities. The oil quality parameters were assessed using free fatty acid value, iodine, acidity index, saponification, refraction and specific gravity, found that planting distance does not affect the quality of oil. Key words: Castor bean, castor oil, biofuels, seed yield, oil yield. Se evaluaron cuatro materiales de higuerilla en la región media del Valle del Sinú, en el año 2009. Las variables fueron desarrollo fenológico, altura de planta, producción de semillas y rendimiento de aceite, con la finalidad de determinar el mejor material para fines comerciales. Todos los materiales reportaron altos rendimientos en semillas y aceite destacándose el genotipo comercial Nordestina BRS149, con 2,2 t ha-1 en semillas y 47% en aceite. Las distancias de siembra fueron 1,5 x 1,5 m y 2,0 x 2,0 m, con densidades de 6.666 y 3.906 plantas ha-1. Las variables altura de planta, productividad de semillas y rendimiento de aceite, presentaron diferencias significativas para la interacción material × densidad; por otra parte, al comparar la densidad de cada material, solo la producción de semillas mostró diferencias. Estas variables fueron significativamente diferentes entre densidades poblacionales, lo cual muestra que, a mayor altura de planta menor productividad. La distancia de siembra de 2,0 x 2,0 m, proporcionó los valores más altos de productividad de semillas por planta, en tanto que los rendimientos de aceite no presentaron diferencias entre densidades. La calidad de los aceites se evaluó mediante s
