Evaluation of Bibb (Butterhead) Lettuce Cultivars for Hydroponic Production in Saskatchewan Greenhouses (2016) - 3 apges
Lettuce has excellent potential as a greenhouse crop in Saskatchewan. This project evaluated cultivars of bibb-type lettuce for their suitability for hydroponic production in the greenhouse. Performance factors evaluated included speed of development, tolerance of biotic (disease and insects) and abiotic stresses (heat, cold, low light and nutrient imbalances), as well as head size, appearance, texture and flavor. A total of 53 cultivars were tested over 25 production cycles which ran from January 2012 through June 2014. The lettuce was grown utilizing a nutrient film technique hydroponic production system. Cultivars that produced looser heads tended to be higher yielding and had fewer problems with tipburn than the semi-head types.
