Evaluation of seed types and cutting season for the sowing of sweet potato, Ipomoea batatas (l) lam, in the Xaribbean region of Colombia

The objective was to evaluate different branch segments as a source of vegetative seed for sowing and the appropriate time for cutting these. Twelve treatments were evaluated. (apical, preapical, third and fourth section segment), with three cutting times (60, 90 and 120 days after planting), in a r...

Lam, EN LA REGIÓN CARIBE DE COLOMBIA TÁMARA MORELOS, R. E. GARCÍA PEÑA, J. A. ESPITIA MONTES, A. A. REGINO HERNÁNDEZ, S. M. PÉREZ CANTERO, S. P. CONTRERAS SANTOS, J. L. The objective was to evaluate different branch segments as a source of vegetative seed for sowing and the appropriate time for cutting these. Twelve treatments were evaluated. (apical, preapical, third and fourth section segment), with three cutting times (60, 90 and 120 days after planting), in a randomized complete block design, in divided plots, with three repetitions. Seed yield was similar in all treatments, with a general average of 98.73%. The types of segments signifi cantly affect performance, the apical (11,643.96 kg ha -1 ) and preapical (11,101.47 kg ha -1 ) being better than the others. The lowest yield was the fourth section (8,971.07 kg ha -1 ). The cutting time of sections did not affect the yields. However, 60 day cutting time and the apical section are the ones with the highest performance. Economically the best treatment was the apical section combination with a 60-day cut. El objetivo fue evaluar diferentes segmentos de rama como fuente de semilla vegetativa para siembra y la época apropiada para el corte de éstos. Se evaluaron 12 tratamientos (segmento apical, preapical, tercera y cuarta sección), con tres épocas de corte (60, 90 y 120 días después de siembra), en diseño de bloques completos al azar, en parcelas divididas, con tres repeticiones. El prendimiento de la semilla fue similar en todos los tratamientos, con promedio general de 98,73%. Los tipos de segmentos afectan significativamente el rendimiento, siendo mejores el apical (11.643,96 kg ha -1 ) y preapical (11.101,47 kg ha -1 ), que los otros. El menor rendimiento fue la cuarta sección (8.971,07 kg ha -1 ). La época de corte de secciones no afectó los rendimientos. Sin embargo, época de corte 60 días y la sección apical son los de mayor rendimiento. Económicamente el mejor tratamiento fue la combinación sección apical con corte de 60 días.
