Growth and yield of Dutch cucumber grown in a protected environment and with alternative organic substrates ; Crecimiento y rendimiento del pepino holandés en ambiente protegido y con sustratos orgánicos alternativos

The replacement of imported substrates by local materials is a trend in severaltechnifiedproduction systems, given the cost reduction and the importance of agricultural by-products, formerly considered to be waste. The main objective of this work was to validate the effect of different substrates on the growth and productivity of Dutch cucumber plants under greenhouse conditions. The study took place from October 2012 to January 2013, at the Agricultural Experiment Station Fabio Baudrit, Alajuela, Costa Rica. Variety Fuerte was used and four mixed substrates (volume ratio) made of local raw ma... Mehr ...
