The paper presents an efficient form of growing arugula plants by means of automatic control of an aeroponic culture irrigation *** system considers a reprogrammable electronic circuit that uses software to generate different irrigation cycles to obtain an adequate growth of arugula *** show how different samples grown in a greenhouse had the same growth behavior as field-grown samples during the test *** was possible to obtain a more efficient and sustained five-week production to supply consumers by having a continuous cycle irrigation system,which was operated for 35 *** growth and number of leaves were maintained in a similar way for different plants *** grow similarly,but some of them showed size differences during the five weeks.

A model was developed for phosphorus(P)concentration over time in a closed aeroponic coriander *** addition,the setting and starting up of the soilless culture is described,and the measurements of electrical conductivity(EC),pH and concentration of major ions in the mixing tank are *** using mass balance principles,the dynamics of the nutrient concentration in the mixing tank and in the drainage solution are *** series of continuous stirred tank reactors are considered for the flow structure,using a power law relationship to represent the rate of nutrient removal,considering water volume *** concentration measurements were used for model fitting,and the resulting simulation is in good agreement with data.
