13 Which Crops Are Most Salt Tolerant ? Barley, Sugar Beets, and Cotton. Crops differ very much in salt tolerance. Except for a few of the tolerant crops, yields drop off as salinity increases so that there is no "safe limit." If, however, small decreases in yield are permissible, then approximate salt tolerance limits can be given. Plants that can tolerate: Up to 8-161 millimhos Only up to 4-8 millimhos No more than 2-4 millimhos Barley, Beets, Cotton Saltgrass Bermuda grass Barley hay Garden beets, Kale Asparagus Spinach Date FIELD CROPS Rye, Wheat, Oats, Sorghum, Corn, Flax FORAGE CROPS Sweet clover, Dallis grass, Sudan grass, Alfalfa, Tall fescue, Wheat, and Oat hays, Orchard grass, Vetch VEGETABLE CROPS Tomato, Broccoli, Cabbage, Lettuce, Sweet corn, Peppers, Squash, Carrots, Onion, Peas, Cucumber FRUIT CROPS Pomegranate, Fig, Olive, Grape, Cantaloupe Field beans White clover Ladino clover Radish Celery Green beans Pear, Apple, Orange, Grapefruit, Plum, Apricot, Peach, Lemon Within each group, field, forage, vegetable, and fruit, crops are listed in order of decreasing salt tolerance. The values in millimhos at the head of each column give the approximate range of salinity that can be tolerated by the crops in that column. 1 Electrical conductivity of saturation extract of the soil.
