Aporte económico de la madera de cedro (Cedrela odorata L.) como árbol de sombra en cafetales de Pérez Zeledón, Costa Rica
'Instituto Tecnologico de Costa Rica', 2021Co-Authors: Calvé Jarque Sergio, Murillo Olman, Salazar Luis, C´órdoba DónaldAbstract:The study determined the economical contribution of cedar wood (Cedrela odorata L.) in agroforestry systems with coffee in Costa Rica. 26-coffee farms associated to CoopeAgri R.L. in Pérez Zeledón county. Cedar has been planted as a shade tree in coffee production areas in this county, with an average density of 214 trees/ha, which corresponds to a 7x7 m spacing, but it varies from 70 to 700 trees. Cedar in coffee plantations registers a growth rate of 2.5 cm/year in diameter, which allows it to reach 40 cm in dbh at 16 years of age. Planting cedar in coffee areas produce economical incomes from wood sales of approximately $ 5000ha-1 and a total commercial volume of 100 m3 ha-1 in 16 years. From this amount 60 % has commercial value for sawmill industry in its 6 m merchantable stem. Meanwhile, fuelwood represents 35 % of total volume, but only 8 % of the total tree value. Good silvicultural management techniques, like crown prunning and Hypsipyla grandella attack prevention, with an initial density of 277 trees (6 x 6 m that will be thinned to 12 x 6 m at age 8) may increase the wood value up to $7000ha-1. Cedar trees planted in agroforestry systems with coffee, is an excellent option that enhances higher incomes for producers.La investigación estimó el aporte económico de la madera de Cedro (Cedrela odorata L.) por medio de árboles de sombra en sistemas de producción de café. Se censaron lotes productivos en 26 cafetales de productores asociados a la Corporación Coopeagri R.L en el cantón de Pérez Zeledón. El cultivo de cedro en cafetales de la región se maneja a una densidad promedio de 214 individuos ha-1, que corresponde a un espaciamiento de 7 m x 7 m, no obstante, se registró una significativa variación desde 70 hasta 700 individuos. El cedro en cafetales tiene una tasa de crecimiento de 2,5 cm año-1, que le permite alcanzar los 40 cm en el DAP a los 16 años de edad. El cultivo de cedro en los cafetales produce ingresos económicos por la madera, de aproximadamente $5000 ha-1 y un volumen comercial de 100 m3 ha-1 en 16 años, del cual, el 60 % tiene valor comercial para aserrío en 6 a 7 m de fuste. La leña representa un 35 % del volumen total, pero tan solo un 8 % del valor comercial del árbol. Con buenas prácticas silviculturales de manejo de copa y de reducción del ataque de Hypsipyla grandella, con una densidad inicial de 267 árboles (5 x 7,5 m que se reduce a 160 al año 8), el valor de su madera podría alcanzar los $7000 ha-1. El cedro en sistemas agroforestales asociado con café es una excelente opción de diversificación productiva para sus productores

Estimación del aporte económico de la madera de cedro (Cedrela odorata L.) en sistemas agroforestales (SAF) con café en la zona de Pérez Zeledón, Costa Rica
'Universitat Politecnica de Valencia', 2019Co-Authors: Calvé Jarque SergioAbstract:[ES] La investigación estimó el aporte económico de la madera de Cedro (Cedrela odorata L.) por medio de árboles de sombra en sistemas de producción de café. Se censaron lotes productivos en 28 cafetales de productores asociados a la Corporación Coopeagri R.L en el cantón de Pérez Zeledón. El cultivo de cedro en cafetales de la región se maneja a una densidad de 214 individuos/ha, que corresponde a un espaciamiento de 7 m x 7m. El cedro en cafetales tiene una tasa de crecimiento de 2,5 cm/año, que le permite alcanzar los 40 cm en el DAP a los 16 años de edad. El cultivo de cedro en los cafetales produce ingresos económicos por la madera, de aproximadamente $400/ha/año y un volumen comercial de 113 m3 /ha en 16 años, del cual, el 60% tiene valor comercial para aserrío en 6 a 7 m de fuste. La leña representa un 35% del volumen total, pero tan solo un 8% del valor comercial del árbol. Con buenas prácticas silviculturales de manejo de copa y de reducción del ataque de Hypsiphylla grandella, podría aumentarse la densidad del cultivo y la producción, en más de un 50% de madera comercial/ha. El cedro en sistemas agroforestales de café es una excelente opción de diversificación productiva para los productores.[EN] The project to be carried out, will try to count the economic contribution of Cedar (Cedrela odorata L.) in agroforestry systems with coffee in Costa Rica. Through measurements made in the cooperative CoopeAgri R.L. The commercial height (HC) and the diameter (DAP) at chest height (1.20 m) will be measured. With these values the commercial volume will be obtained and in this way the economic and social contribution for the producers will be counted. Cedar in agroforestry systems is an excellent alternative for productive diversification and income for producers. The agroforestry crops are of great help, since with them you can obtain several rents in the crops. The cedar will help the coffee plantations both in improving incomes and providing shade for the coffee crop, thus helping the producers.Calvé Jarque, S. (2019).

Cedrela odorata L. TEM POTENCIAL PARA SER UTILIZADA NA SILVICULTURA PÓS-COLHEITA NA AMAZÔNIA BRASILEIRA?
'Universidad Federal de Santa Maria', 2018Co-Authors: Vieira, Sabrina Benmuyal, João Olegário Pereira De ,carvalho, Gomes, Jaqueline Macedo, Joice Carolina Fernandes Da ,silva, Ruschel, Ademir RobertoAbstract:This study deals with the performance of Cedrela odorata L. (cedar) seedlings planted in gaps in the municipality of Paragominas, state of Pará, Brazil. The survival and growth rates of seedlings were evaluated in order to find out the possibility of planting them in gaps caused by the reduced impact logging in the Brazilian Amazonia. Four hundred gaps were chosen in 200 ha and they were divided in three size classes: small (200–400 m²), medium (401–600 m²) and large gaps (> 600 m²). Four hundred and seventy seedlings of cedar were planted in 236 gaps in 2005, when the first assessment was carried out. Other assessments occurred in 2006, 2008 and 2010. Five years after planting the survival of seedlings was circa 81,8% and the mean growth rate was 70,0 cm year-1 in height and 0.23 cm year-1 in diameter. Therefore, we can suggest Cedrela odorata L. for enrichment planting in forests after logging, considering its good performance in gaps. Continuous monitoring is needed.Avaliou-se o desempenho de mudas de Cedrela odorata L. (cedro), plantadas em clareiras causadas pela exploração florestal de impacto reduzido, no município de Paragominas, no Estado do Pará. Analisou-se a sobrevivência e o crescimento das mudas para estudar a possibilidade de utilizá-las em enriquecimento de clareiras, na Amazônia brasileira. Em 200 ha foram selecionadas 400 clareiras, divididas em três classes de tamanho: pequenas (200–400 m²), médias (401–600 m²) e grandes (> 600 m²). Em 236 dessas 400 clareiras foram plantadas 470 mudas de cedro, em 2005, quando também foi realizada a primeira avaliação da sobrevivência e do crescimento das mudas. Outras avaliações foram realizadas em 2006, 2008 e 2010. Constataram-se, após os cinco anos de monitoramento, altas taxas de sobrevivência, em torno de 81,8%, e de crescimento com média de 70,0 cm em altura e 0,23 cm em diâmetro. Portanto, pode-se inferir que Cedrela odorata se adapta a ambientes de clareiras e poderá ser indicada para plantios de enriquecimento de florestas após a colheita da madeira. Há a necessidade de continuar o monitoramento
