Crecimiento y rendimiento del pepino holandés en ambiente protegido y con sustratos orgánicos alternativos Cinthya Meneses-Fernández Gustavo Quesada-Roldán Agrociencias Cucumis sativus cultivo protegido Cultivo sin tierra desechos agrícolas hortalizas cucurbitáceas La sustitución de sustratos importados por materiales locales es una tendencia en varios sistemas de producción tecnificada en ambientes protegidos, dado que se reducen los costos y se valorizan subproductos agrícolas anteriormente considerados como desecho. El objetivo de este trabajo fue validar los efectos de diferentes sustratos en el crecimiento y la productividad de plantas de pepino holandés establecidas en invernadero. El trabajo se llevó a cabo entre octubre 2012 y enero 2013, en la Estación Experimental Fabio Baudrit, Alajuela, Costa Rica. Se empleó la variedad Fuerte y cuatro sustratos en mezcla (base volumen), elaborados a partir de materias primas locales como fibra de coco (FC), fibra de palma (FP), abono orgánico (ABO) y aserrín (AS), y un tratamiento comercial (testigo), constituido por tabletas de fibra de coco. Se evaluó el contenido de humedad en los sustratos, el crecimiento de la planta (fase vegetativa) y el rendimiento, según categorías de clasificación comercial por tamaño (S, M, L, XL y rechazo). El crecimiento de plantas de pepino holandés variedad Fuerte, fue mayor en sustratos con fibra de coco al 40% + fibra de palma al 40% + abono orgánico comercial al 20%, y fibra de coco al 70% + abono orgánico comercial al 30%, mientras que, la productividad de esos mismos dos sustratos fue de 15,57 y 15,44 kg/m2, respectivamente. Ambos tratamientos fueron estadísticamente iguales al sustrato comercial de fibra de coco empacado en tabletas, que obtuvo un rendimiento de 14,77 kg/m2. Resultado atribuido al aporte nutricional del abono orgánico alto en K, Ca y Mg y a los efectos de la aireación y retención de humedad de las fibras. 2018 artículo científico 2215-3608 https://www.redalyc.org/articulo.oa?id=43755165001 https://www.redalyc.org/journal/437/43755165001/ https://www.redalyc.org/journal/437/43755165001/html/ https://www.redalyc.org/journal/437/43755165001/43755165001.epub https://www.redalyc.org/journal/437/43755165001/movil https://doi.org/10.15517/ma.v29i2.28738 es http://www.redalyc.org/revista.oa?id=437 Agronomía Mesoamericana application/pdf Universidad de Costa Rica Agronomía Mesoamericana (Costa Rica) Num.2 Vol.29
