Irrigation management

The hypothesis was that the water supply according to full evapotranspirometric demand influenced nutrient uptake, plant growth and edible flower production in the pansy crop. The water mass, lost by evaporation of the substrate, was converted into water slides to be irrigated in the culture pots, according to different levels of irrigation, being 120%, 100%, 80%, 60% and 40% replenishment of water evaporation, under greenhouse conditions. Data of temperature and relative humidity were collected inside the greenhouse during the execution of the experiment.
