“…Then, July is the month when the fertilizer was applied the most and entering the dry season. The application in July was intended to determine the production so that fertilization effectiveness can be seen on the productivity of fresh oil palm fruit bunches during dry season fertilization (Darko et al, 2020).…”

The productivity of oil palm is highly dependent on the application of fertilization. Fertilizer applications must pay attention to its effectiveness and efficiency so that nutrients are absorbed optimally at the right time and right dosage. This research was conducted to assess the effectiveness of fertilization time. In addition, this also aimed to examine the effectiveness of oil palm fertilization which affects the productivity of fresh fruit bunches (FFB) and increases the production income. The data used were secondary data including fertilization and productivity of FFB at time intervals after fertilization for 6, 7, and 8 months in Kujan Estate Division, PT Menthobi Makmur Lestari (MMaL), Kujan Village, Nanga Bulik District, Lamandau, Central Kalimantan Province. The data obtained were analyzed using MS software. Excel was also employed to describe the dosage and time applied for 1 year and the productivity of FFB after 6 months of fertilization. Fertilizer application in months with high rainfall and long dry season is less effective and efficient for nutrient availability. The productivity of FFB in the second semester after 6 months of fertilization has increased compared to the first semester. The effective application of fertilizers can increase the production of CPO and reduce the total maintenance cost of the oil palm company

“…Such reported low sweetpotato yields in West African countries ranged from 1.8 to 7.4 t/ha. For improved OFSP, reported field yields were estimated below 6 t/ha in Nigeria, 51 and 10 t/ha in Ghana 52 . There is a need to improve local cultivars exhibiting high and stable yield potential to substitute low yielded varieties predominantly used by farmers for root production.…”

Orange‐fleshed sweetpotato production: Progress and perspectives for value chain development in West Africa

Africa and Asia bear the greatest cases of vitamin A deficiency whereas Orange-Fleshed Sweetpotato (OFSP) as a possible solution to vitamin A deficiency, brings income, food and nutritional security for smallholders involved in its production. Reports indicated low adoption of OFSP in West Africa due to poor value chains and wide adoption of White-Fleshed Sweetpotato (WFSP). Here, we reviewed OFSP interventions and programmes undertaken in West Africa, identified constraints limiting OFSP production, and updated the required actions for OFSP value chains development in West Africa. We reported 10 significant interventions and 20 released OFSP varieties within 4 countries. The main bottlenecks to OFSP value chains development are the lack of improved cultivars exhibiting high and stable yield potential, predominance of WFSP, non-exposition of whole population to OFSP varieties, limited number of improved OFSP varieties available, and inadequacy of improved OFSP varieties to smallholder preferences. The roles of donors, research institutions, local partners, and smallholder's contributions in increasing OFSP production and consumption are provided. This will fuel the development of strong OFSP value chains in West Africa.

“…El rendimiento de camote puede ser influenciado por factores ambientales (temperatura, humedad), edáficos (textura, estructura, CIC, pH, fertilidad química, física y biológica), biológicos (plagas, calidad de la semilla) y aspectos socioeconómicos (tipo de agricultor, tenencia de tierras, tecnología y manejo del cultivo) (Cuzumano y Zamudio, 2013; Darko et al, 2020;Montaldo, 1991;Shi et al, 2021, Pinedo et al, 2017Valverde-Reyes y Pinedo-Taco, 2022).…”

“…Entre los factores antes indicados en el manejo del cultivo, referidos la calidad de semilla, densidad de siembra y las dosis de fertilización y las condiciones climáticas pueden ser limitantes para la producción sostenible (Darko et al, 2020;González et al, 2020;Pinedo et al, 2017;Valverde-Reyes y Pinedo-Taco, 2022). Según las condiciones idóneas para su cultivo son una temperatura media durante el período de crecimiento, superior a los 21 ºC, y un ambiente húmedo (80-85 %) (Flórez et al, 2016).…”

“…En relación a los niveles de fertilización el cultivo de camote es poco exigente en nutrientes, produce en suelos pobres siempre que exista humedad suficiente de mediana calidad o poco preparados (Gonzáles et al, 2020). Sin embargo, el cultivo continuo resulta en el agotamiento de la materia orgánica y nutrientes minerales del suelo, de ahí la necesidad de fertilización (Darko et al, 2020). Las cantidades bajas o excesivas de nitrógeno pueden ser perjudiciales, afectando negativamente su potencial de rendimiento; no se requieren altos niveles de nitrógeno para iniciar la formación de raíces tuberosas (Cusumano y Zamudio, 2013;Montaldo, 1991).…”

El cultivo de camote da seguridad alimentaria porque se produce satisfactoriamente en suelos marginales; sin embargo, el uso de esquejes-semilla de calidad, fertilización y una adecuada densidad de siembra pueden incrementar los rendimientos y la calidad comercial. El objetivo de la investigación fue evaluar el efecto de la densidad de siembra y dosis de fertilización en el rendimiento de raíces reservantes de tres clones avanzados de camote bajo condiciones del distrito de San Vicente de Cañete, Lima, Perú. El estudio se realizó bajo un diseño de bloques completos al azar en arreglo factorial 3x2x2, con cuatro réplicas. Se evaluó el comportamiento agronómico de tres clones de camote (C1 = anaranjado, C2 = amarillo y C3 = morado) dos densidades de siembra (D1 = 33 333 y D2 = 50 000 plantas ha-1) y dos dosis de fertilización (F1 = 60-40-100 de NPK y F2 = 80-60-120 NPK). Las variables en evaluación fueron rendimiento total y comercial, materia seca e índice de cosecha. Los resultados indican la ausencia de efecto combinado, los factores en estudio actuaron en forma independiente, el tratamiento C1F1D2 (clon anaranjado + dosis de fertilización 60-40-100 NPK + 33 333 plantas ha-1) presenta el mayor rendimiento total, superior en 186.72 % al tratamiento C2F1D2 (26.58 t ha-1; p>0.05). El C1, independiente de las dosis de fertilización y densidad de siembra presenta el mayor rendimiento (64.87 t ha-1; p<0.05). Se concluye que los tres clones (C1>C2>C3) superan el rendimiento promedio nacional y se perfilan como nuevas variedades promisorias para reemplazar a las variedades que han mermado su rendimiento en los últimos años. A mayor densidad de plantas menor rendimiento debido a la mayor competencia intraespecifica por recursos; asimismo, dosis medias de fertilización (D1) complementadas con materia orgánica cubren los requerimientos nutricionales del cultivo.
