Availability of iron in hydroponic nutrient solutions for rose crops
Lykas, C.; Giaglaras, P.; Kittas, C. (2001)This study investigated the effect of light and agitation on the availability of iron in hydroponic nutrient solutions. In recycled hydroponic nutrient solutions used for the cultivation of roses, iron is added usually in ... -
Daily temperature optimisation in greenhouse by reinforcement learning
Tchamitchian, M.; Kittas, C.; Bartzanas, T.; Lykas, C. (2005)The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously ... -
Effect of olive mill wastewater on growth and bulb production of tulip plants infected by bulb diseases
Lykas, C.; Vagelas, I.; Gougoulias, N. (2014)The effect of olive mill wastewater (OMW) on growth of tulip plants infected by common diseases as well as on their new bulbs production is analyzed in this work. Filtered and sterilized OMW was tested as growth inhibitor ... -
Electrical conductivity and pH prediction in a recirculated nutrient solution of a greenhouse soilless rose crop
Lykas, C.; Katsoulas, N.; Giaglaras, P.; Kittas, C. (2006)The influence of nutrient solution (1) mixing rate, and (2) time of use on pH and electrical conductivity (EC) of a recirculated nutrient solution used for the irrigation of a greenhouse soilless rose crop was studied. ... -
Gardenia jasminoides Height Control Using a Photoselective Polyethylene Film
Lykas, C.; Kittas, C.; Katsoulas, N.; Papafotiou, M. (2008)The use of chemical growth retardants is a standard practice for compact gardenia plant production. The aim of this study was to investigate the possibility of using a photoselective polyethylene greenhouse covering film ...
