Water consumption of three ornamental species with the suction irrigation system

Objective: To evaluate water consumption in ornamental plants (geranium, gazania and petunia) two substrates with different particle sizes (fine coarse) of tezontle peat moss, through a suction irrigation system, which uses porous capsules as emitters. Design/methodology/approach: The experimental design was complete randomized blocks, six treatments (three species substrates) four repetitions (24 units). first mixture contains fine substrate (composed size less than 0.4 mm) 1:2 v/v ratio; the second presents coarse between 0.4-0.6 1:1 v/v. Results: In consumption, there are significant differences by type substrate, where system has ability to self-regulate. highest petunia (which higher proportion moss its composition). Limitations on study/implications: With use protected agriculture, rural urban orchards, gardens, walls green roofs research purposes. Findings/Conclusions: capacity continuously supply demanded plant-substrate-atmosphere system.
