Automated ebb-and-flow subirrigation for citrus liners production. I. Plant growth

A cost-effective and customizable automated irrigation system for precise high-throughput phenotyping in drought stress studies

“…The substrate specific calibration was fundamental to obtain accurate measurements in line with the manufacturer specifications for custom calibration [ 17 , 18 ]. The linear relationship observed between the EC-5 output and VWC in the range of water content used herein is in agreement with previous studies, as demonstrated by the R 2 values (0.92–0.98) [ 36 , 37 , 38 ].…”

“…One of the possible concerns of this type of irrigation system is the limited volume of influence of the dielectric sensors for accurate measurements. The EC-5 sensor selected for our irrigation system has been successfully used in experiments with small to medium pots [ 37 ], and in a wireless network of soil sensors deployed to the field [ 47 , 38 ]. Considering that these sensors can overestimate VWC of large pots (i.e.…”

Advances in citrus propagation in Brazil

“…Studies on using ebb-and-flow subirrigation for citrus production were started in Brazil in 2005 at the University of Campinas's School of Agricultural Engineering (Campinas, SP, Brazil), and have been providing critical information regarding the use of this system at a large scale. These studies include the determination of the relationship between the water level height and the water retention time in the substrate in subirrigation systems (FERRAREZI et al, 2017a), and the validation of operational parameters for the use of subirrigation benches (RIBEIRO et al, 2017). Studies on the effect of subirrigation on the production of citrus rootstock liners were described by Ferrarezi & Testezlaf (2017a.…”

Studies on the effect of subirrigation on the production of citrus rootstock liners were described by Ferrarezi & Testezlaf (2017a. The results of these studies demonstrated that ebb-and-flow subirrigation could be successfully used to produce 'Rangpur' lime liners, shortening the crop cycle by 30 days by anticipating the time of transplantation for grafting and allowing for the production of Phytophthorafree trees compared to when trees were irrigated manually by overhead irrigation using breaker nozzles.…”
