“…Therefore, predicting whether the EC will increase or decrease in the future can help with sophisticated nutrient control. Because nutrient solution control depends on a contemporary EC in current soilless cultures (Neto et al, 2014; Kinoshita et al, 2016), predicted 3-h EC might improve the accuracy of nutrient control. In addition, since the RMSE did not change much near the test accuracy of 0.08 after the 9 h, it can be said that stable forecasts during a day are possible.…”

“…Although various prediction methods have been developed, nutrient control systems are usually based on contemporary EC monitoring and are vulnerable to ion balance in root-zone nutrient solutions (Neto et al, 2014; Kinoshita et al, 2016). These limits result from crops influencing changes in EC and from growth environments (Dewir et al, 2005; Stutte, 2006; Shin and Son, 2016).…”

“…Em casa de vegetação, sistemas automáticos de controle dos eventos de aplicação de água e do preparo de soluções nutritivas para implementação da fertirrigação têm sido propostos por diversos pesquisadores, com o objetivo de avaliar a resposta dinâmica destes sistemas diante de alterações das condições meteorológicas do ambiente de cultivo (DOMINGUES et al, 2012;ROMERO et al, 2012;STEIDLE NETO et al, 2014). Nestes estudos, o desempenho do sistema no controle da duração e da frequência de irrigação é avaliado a partir da quantificação de indicadores de crescimento e de produtividade ao longo do ciclo da cultura.…”

“…The experiment was conducted at the Diogo Alves de Mello Experimental Field of the Federal University of Viçosa, in Viçosa, state of Minas Gerais, Brazil. The region has a Cwa, hot temperate mesothermic climate, with rainy summer and dry winter, according to the Köppen classification (STEIDLE NETO;ZOLNIER;LOPES, 2014). Tomato (Solanum lycopersicom) plants of the cultivar Santa Cruz Kada (Paulista) were grown from September 4 to September 29, 2017.…”
