“…Yam belongs to the family of Dioscoreaceae and to the genus Dioscorea L which comprise of about 600 species [1]. The most important edible yam known is believed to have originated in the tropical area of South East Asia, South America and Africa [2].…”

Evaluation of the effect of pre-harvest treatments (inorganic fertilizers and organic manure application) on the yield and storability of yam tubers was investigated. An experimental plot was chosen and cleared, ridges were prepared into which yam seedlings were planted and used for the study. A randomized complete block design (RCBD) was applied. The yam plants were nurtured till maturity and tubers were then harvested. The harvested yam tubers' parameters such as middle diameter, mass, length were measured and recorded. The collected data were analyzed to test the research hypothesis. Results show that pre-harvest treatments had positive effects on the yield but negative effect on the storability of yam tubers. It is therefore recommended that prior to application of treatments like fertilizer, the possible duration of storage of yam tubers intended for cultivation should be considered in order to choose a suitable treatment for yam production. Where organic manure is to be used, it should be applied at least three days before planting of yam seedlings into the field. The research successfully evaluated the effects of pre-harvest treatments on the yield and storability of yam tubers and also provided experimental data being potential resources for future researchers.

“…Los tubérculos son fuente importante de carbohidratos, proteína y fibra (Adjebeng et al, 2021;Worojie et al, 2021). De 682 especies reconocidas en el mundo, solo D. alata (ñame criollo), D. bulbifera (ñame papa), D. cayenensis (ñame amarillo), D. dumetorum (ñame trifoliado), D. esculenta (ñame ñampi) y D. rotundata (ñame espino) se cultivan como alimento (Pachakki et al,2021;Waris et al,2021).…”

Desde los inicios de la agricultura, los cultivos han sido propensos al ataque de diversas plagas que reducen los rendimientos y la productividad. Por tanto, se hace indispensable conocer la biología y el comportamiento de los artrópodos plagas para establecer planes de manejo integrado que permitan reducir los daños y maximizar la producción de alimentos para satisfacer la demanda alimenticia de una población en aumento. En la subregión de Montes de María en Colombia, durante los últimos años se han reportados daños por plagas de las cuales se desconoce su identidad taxonómica, incidencia, y capacidad de daño. En este sentido, Agrosavia C.I Turipaná desarrolló una investigación con el fin de identificar y caracterizar los daños causados por artrópodos plagas en Dioscorea alata y D. rotundata en los municipios de Carmen de Bolívar (Bolívar) y Chalán (Sucre) durante la etapa vegetativa. El monitoreo de los artrópodos se realizó con frecuencia quincenal y en cada muestreo fueron registrados los daños y tipos de artrópodos encontrados en hojas y tallos de la planta. Los resultados evidenciaron que en ambas localidades y especies de ñame las hojas de la planta fueron afectadas por cinco artrópodos plagas del orden Coleóptera (familia Chrysomelidae) y tres Hemípteros de la familia Cicadellidae y Miridae. Los daños encontrados en el tallo estuvieron asociados a Xystus sp. Las evaluaciones de artrópodos plagas en ñame constituyen una estrategia para la prevención de riesgos sanitarios en la especie, lo que contribuye a la producción ecoeficiente de tubérculos.
