Manejo del material de siembra de yuca (Manihot esculenta Crantz)
Several cassava trials were planted at CIAT to study the effect of the maturity of stem cuttings, depth of planting, cutting length, planting position and the angle of the cut on root yield. Cuttings from the top and middle part of vigorous 1-yr-old plants produced greater than root yields than thos...

| description | Several cassava trials were planted at CIAT to study the effect of the maturity of stem cuttings, depth of planting, cutting length, planting position and the angle of the cut on root yield. Cuttings from the top and middle part of vigorous 1-yr-old plants produced greater than root yields than those proceeding from the lower part of the plant or from older stem parts. Cuttings planted vertically 10, 20 and 30 cm deep do not affect the yield but do affect root distribution, the no. of roots/plant and the difficulty of harvesting; planting at 10 cm in depth was the most adequate. Twenty-cm long, selected and treated cuttings gave slightly higher yields than 40 or 60 cm ones. Cuttings placed vertically assure more rapid emergence, greater than percentage of germination, greater than yields and prevent lodging in comparison to those planted in a horizontal or inclined position. When the stems were cut rectangularly or bevel-edged, different rooting systems were produced; the former produced roots with a more uniform distribution; nevertheless, yield was not affected. Vertical planting, either with a straight or bevel-edged cut, gave greater than yields than horizontal planting. To obtain max yields, planting material should be selected from the middle part of mature, vigorous plants, cut at right angles 20 cm long and planted vertically 10 cm deep. (AS-CIAT) |

(AS-CIAT) Se sembraron varios ensayos de yuca en el CIAT para estudiar el efecto de la madurez de las estacas, profundidad de siembra, longitud de la estaca, posicion de siembra y angulo de corte de la misma, en el rendimiento de las raices. Las estacas de la parte media y superior de plantas vigorosas de un ano de edad produjeron mayores rendimientos de raices que aquellas provenientes de la parte baja de la planta o de estacas viejas. Las estacas sembradas verticalmente a 10, 20 y 30 cm de profundidad no influyen en el rendimiento, pero afectan la distribucion de raices, el numero de raices/planta y la facilidad de cosecha; la siembra a 10 cm de profundidad fue la mas adecuada. Las mayores estacas de 20 cm de largo seleccionadas y tratadas dieron rendimientos ligeramente mayores que las de 40 o 60 cm. La siembra vertical de las estacas aseguro una emergencia mas rapida, un mayor porcentaje de germinacion, mayores rendimientos y previno el volcamiento de las plantas, en comparacion con la posicion horizontal o inclinada. El corte de la estaca en forma rectangular o en bisel produjo diferentes sistemas de enraizamiento; el primero produce raices mas uniformemente distribuidas; sin embargo, no afecta el rendimiento. La siembra vertical, ya sea con angulo de corte recto o en bisel, da mayores rendimientos que la siembra horizontal. Para obtener los rendimientos maximos, el material de siembra se debe seleccionar de la parte media de plantas vigorosas maduras, cortado en un angulo recto, en trozos de 20 cm de largo y sembrado verticalmente a 10 cm de profundidad.
