„Áhrif ljósstyrks á vöxt, uppskeru og gæði gróðurhúsajarðarberja að vetri“ : final report

Abstract

In Iceland, winter production of greenhouse crops is totally dependent on supplementary lighting and has the potential to extend seasonal limits and replace imports during the winter months. Adequate guidelines for winterproduction of strawberries are not yet in place and need to be developed. The objective of this study was to test if winterproduction of strawberries in possible in Iceland and if the light intensity is affecting growth, yield and quality of different strawberry varieties and to evaluate the profit margin.
