Alfalfa yields decrease when water supply is inadequate. In drought years, starting and continuing with full irrigation until the water supply has been exhausted will limit full production to earlier harvests. The objective of this study was to examine the effect of discontinued irrigation on alfalfa yield during the irrigation season and when water supply is restored in the following year. Three irrigation levels, water for two harvests (i1), water for 3 harvests (i2), and water for four harvests (i3), were imposed in 1981-83 and one irrigation level (i3) in 1984. Yield response was compared among i1-i3 by harvest for 1981-83 and separately for 1984, between flood and sprinkler irrigation, and between drainage and no drainage. Generally, yields were significantly less for nonirrigation conditions, they fully recovered in 1984 after three years of deficit irrigation, yield of harvests 1 did not differ between 1984 and 1982-83, drainage condition did not affect yield, and irrigation method had a significant influence on yield for harvests 3 and 4 in 1981-83.

In the absence of irrigation, water from a water table below the root zone can sometimes sustain crop growth. This study was conducted to determine whether alfalfa grown without irrigation, but in the presence of water table below the root zone, can give normal yields. Three irrigation treatments were applied: irrigating during the first two growth cycles, irrigating during the first three growth cycles, and no irrigation restrictions for the four growth cycles of the irrigation season. Water-table depths midway between parallel tile drains were evaluated. Yields from the midway position between drains were compared with yields nearer the drains. The influence of occurrence/nonoccurrence of irrigation on yield was also tested by regression analysis. Water tables tended to be deeper in the absence of irrigation but differences were small among the three treatments. Yield was dependent on the occurrence of irrigation but not on water-table depth. Most important, nonirrigation caused an 80% drop in yield.

A prototype system of subsurface drains for collection of shallow groundwater and reuse of drainage water for reuse in irrigation was examined. The system involved a field with subsurface drains, a reservoir for storing drainage water, and conveyance facilities for irrigation with drainage water. Benefits of recycling include the reduction in demand for fresh water, improvement of drainage within an irrigation project, and reduction of pollutant discharge into wetlands.

Drainage water was collected by subsurface drains and reapplied to half of a drained alfalfa field in Fallon, Nevada, during the 1989 irrigation season. Irrigation district water was applied to the other half of the field. The drainage water quality was analyzed for plant tolerance. The drainage water did not violate irrigation guidelines.
