Variation in Water Use of Container-Grown Plants

Richard P. Regan

pp: 310-312


The nursery industry is taking steps to reduce its use of irrigation water. Public concerns about water use and pollution prevention and increasing irrigation costs are motivating this change. Kabashima (1993) believes nurseries will reduce water use by recycling water, increasing the water application uniformity, and by improving irrigation scheduling. Water is conserved when irrigation is scheduled to apply only the amount of water used by the plant. Growers have found that certain plants need more water than others, while other plants are easily over-watered. Burger et al. (1987) showed that water use varied greatly between different plant varieties when they reached market size.

The amount of water used by container-grown plants is influenced by the climate, production practices, and crop characteristics (Regan, 1991). Plants use the most water on sunny days that are hot, dry, and windy. Growers can use local daily meteorological data or reports to schedule
