Drought Planning for Vegetable Production

  • Author(s): Cahn, Michael

When water is in short supply, growers must estimate how much water their crops require, as well as how much water is available, to determine how much land can be planted and irrigated. Growers can arrive at these estimates by performing calculations that take into account crop water requirements such as evapotranspiration and salt management; available irrigation water; and available non-irrigation water sources such as rainfall, fog, and shallow groundwater. Performing these calculations will allow growers to make informed decisions about how many acres to plant.
