Objective:
The objectives of this cooperative research project are to assess irrigation method (scheduling) and substrate composition on plant growth and physiology, on water efficiency, and on substrate physical and chemical properties for selected containerized nursery crops.

Approach:
Record effluent volume and calculate water use efficiency, determine top and root growth, determine plant tissue and substrate nutrient content, for selected containerized nursery crops under various irrigation schedules (volume and timing) and substrate compositions (varying components). Measure physical characteristics of test container substrates.
