| Abstract:
Processing tomato was grown with drip irrigation in the presence of shallow, saline groundwater to determine the amount of shallow groundwater that can be used by plants without reducing yield. This experiment consisted of applying irrigation water at amounts of 90 percent, 75 percent, 60 percent, 45 percent, and 30 percent of the maximum potential evapotranspiration. Results showed no statistical differences in crop yield between these treatments at two locations. These results indicate that processing tomato can use substantial amounts of saline groundwater without reducing yield. However, a third location where no shallow groundwater exists showed significant yield reductions with decreasing applied water. | |
