Benefits and limitations in breeding salt-tolerant crops Michael C. Shannon Calvin 0. Qualset ome crops, such as cotton, bar- ley, safflower, or sugarbeet, can be grown in relatively saline soils; others, including beans and corn, can be grown only in nonsaline soils. It is intriguing to speculate that a sensi-. The need to produce salt‐tolerant crops was evident in ancient times (Jacobsen and Adams, ) and the possible ways to increase tolerance have been extensively rehearsed. Epstein et al. () described technical and biological ‘fixes’ to the problem of by:
The salinity tolerance of a crop relates to its inherent ability to yield economic product while subjected to root-zone salinity. Tall wheatgrass [Thinopyrum ponticum (Podp.)Liu & Wang, previously Agropyron elongatum (Horst.)Beauv.] ranks as one of the most salt-tolerant forage crops, but producers feeding or grazing livestock with it often report of its poor by: Crop tolerance to seawater. Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water and seawater. There are crops that can grow on seawater and demonstration farms have shown the feasibility.
Salt-Tolerant Forages for Irrigated Areas By Amy Spillman Alfalfa may help solve a problem that’s been plaguing farmers and land managers for years in California, according to scientists with the Agricultural Research Service and their collaborators.. The state’s San Joaquin Valley is one of the world’s most productive agricultural areas, sometimes referred to as “the. Some highly tolerant plants have little economic value and/or their production on salty soil may be very low. Some plants are known to be salt tolerant in the mature stage but sensitive in the seedling stage. This study concerns the emergence and survival of certain forage plants when seeded in a saline : Devere Richard McAllister.

Crop Salt Tolerance. Stephen R. Grattan, University of California, Davis. Soil salinity is an important stress affecting irrigated crops in many areas of California.
This stress is often exacerbated during drought years. Over time, salts can accumulate in the soils as crops extract water leaving the salts behind in the root Size: KB. Salt tolerance of certain forage cropsAuthor: Sadegh Madjidi Ahi. The salt tolerance of a crop can best be described by plotting its relative yield as a continuous function of soil salinity.
For most crops, this response function follows a sigmoidal relationship. However, some crops may die before the seed or fruit yields decrease to.

However, the value of certain salt-tolerant forage crops has been recognized by their incorporation in the rangelands improvement programs in many salt-affected regions throughout the world. Although economic consideration of halophytes and other salt-tolerant plants is just beginning, they are now receiving increased attention particularly in arid regions where salinity problems are very by: to plant salt-tolerant crops.
Sensitive crops, such as pinto beans, cannot be managed profitably in saline soils. Table 3 shows the relative salt tolerance of field, forage, and vegetable crops. The table shows the approximate soil salt content (expressed Salt tolerance of certain forage crops book the electrical conductivity of a saturated paste extract (EC e) in dS/m at 25 degrees C)File Size: KB.
The development of new improved salt-tolerant forage crops gives forage producers an additional means of minimizing salinity-related production losses and an opportunity to improve profits by fully utilizing all the farm ground available to them.
is a long-lived, drought tolerant, hardy pasture grass. It has good salt and drought tolerance, but poor tolerance to spring flooding and saturated soils. Although this grass begins growth early in spring, it provides good late-season forage, due to good curing characteristics.
It is difficult to establish, as seedlings do not compete well withFile Size: KB. Barren spots and stunted plants may appear in cereal or forage crops growing on saline areas.
These factors render the task of evaluating crop salt tolerance data difficult. stone fruits, pome fruits, berries and avocados are all relatively sensitive to salinity. However, certain stone-fruits, citrus and avocado rootstocks differ in.

[Leon Bernstein; United States. Department of Agriculture.] -- This bulletin (1) provides information on the salt tolerance of grasses and forage legumes as an aid in selecting suitable crops for. Forage Crops and Grasses.
It is desirable that the forage crop varieties are also subjected to molecular. clover species for salt tolerance. Intracultivar variation had been identified in.
characterize crop salt tolerance. All crops can tolerate a certain level of salts up to a critical threshold (ECt), beyond which yields decline in a linear fashion. Critical ECt values vary among crops, as do the rates of yield decline with increasing soil salinity (i.e., the slope of yield decline) beyond this Size: 1MB.
Salinity tolerance is influenced by many plant, soil, and environmental factors and their interrelationships. Generally, fruits, vegetables, and ornamentals are more salt sensitive than forage or field crops.
In addition, certain varieties, cultivars, or rootstalks may tolerate higher salt levels than by: The other studies conducted on the relative salt tolerance of crops, cotton, maize, soybean and wheat showed that salt tolerance was associated with high Na + accumulation (Chen and Zhao, ).
Total K + content and Ca 2+ concentrations decreased with an increase in salinity level in the rooting medium. Four halophytic perennial forage grass species, Distichlis spicata, Paspalum vaginatum, Sporobolus virginicus and S. arabicus, were planted in three salt-degraded and abandoned farms at Mezaira’a, Madinat Zayed and Ghayathi in the United Arab Emirates.
The salinity of the irrigation water in the three farms at the time of establishment of the grasses ranged between and dS m–1 Cited by: 5.
The salt tolerance of the six forage species was found to be: salt grass > Bermuda grass > seashore paspalum > Rhodes grass > Kallar grass = alfalfa. In the first season, dry matter yields of salt grass, Bermuda grass and seashore paspalum were not affected by a soil EC e of 14 dS/ by: SJV. Salt-tolerant forage crops that could grow well under saline irrigation would not only increase forage supplies, but could play a key role in drainage water management.
Crop suitability for reuse systems, however, will depend upon the production potential under saline-sodic conditions and the resulting forage quality.
1. Plant cash crops that tolerate salt. With an EC level of about 4 or lower, soil salinity can be stabilized by growing cash crops adapted to moderate soil salinity.
“The most salt-tolerant crops are barley, camelina, rye, safflower, sunflower, and sugar beets,” says Aberle. in the Central Valley of California. Salt-tolerant forages may help provide improved forage supplies. Forage grasses like Bermuda grass (Cynodon dactylon (L.) Pers.) will use more water than most tree species in the same locations because of greater salt tolerance, and have an obvious use for livestock (Oster et al., ).
Using small grains for forage Small grains such as barley, oats, triticale and wheat can be excellent forage crops in the form of pasture, hay and silage. With uncertain weather this spring and summer, planning ahead by planting small grains as an emergency crop is a good idea.Annual crops can be used for mid- to late-summer forage production.
Several of these are described here, and species, seeding rates, and seeding dates are given in the able below. Sudangrass and Forage Sorghums Sudangrass and forage sorghums are .
