What role does drip irrigation scheduling based on crop evapotranspiration (ETc) and soil moisture sensors play in improving water productivity and reducing physiological stress in rose and gerbera?
From my perspective of both theoretical and measurement-based analysis, trickle irrigation, based on ETc and soil water sensors, plays a vital role in:
1. Eliminating water stress for plants' physiological processes
2. Assisting in photosynthesis during the peak transpiration
3. Keeping root in healthy form as ornamental plants are prone to rotting if over-irrigated
4. Ensuring high-quality flower bud, stem, and petal health
5. Confirming higher yield with real-time soil water content measurement from soil moisture sensors
6. Avoiding irrigation mismanagement for shallow-rooted ornamental plants
