Research Project: MEASUREMENT AND MODELING PLANT WATER USE TO QUANTIFY NURSERY WATER REQUIREMENTS

Location: Subtropical Insects and Horticulture Research

2012 Annual Report


1a.Objectives (from AD-416):
The objectives of this cooperative research project are to.
1)apply aerial and substrate water measurement and modeling techniques,.
2)schedule nursery water use by integrating interactions between plant growth environment and recent advances in physiological process modeling of nursery water flux,.
3)move toward the development of a real-time model-sensor integrated system that calculates plant water use on a genotype specific basis, and.
4)move towards quantifying individual nutrient consumption and application across the growing season.


1b.Approach (from AD-416):
Measure inherent plant physiological responses and calculate physiological parameters. Develop process models for plant water use calculations. Simulate, forecast, and prescribe plant water use on a genotypic basis for selected containerized nursery crops under various irrigation schedules (volume and timing).


3.Progress Report:

This project is related to Objective 2 of the in-house project: Effluent Water Quality.

No progress was made during the reporting cycle due to equipment failures and change in experimental setup to measure water use in tree crops. Four peer-reviewed papers, however, associated with the project were published during the reporting period.
