As all major crops, the common bean is a glycophyte, sensitive to salt, and even relatively low soil salinity levels (below 2 dS·m−1) significantly reduce crop productivity [4].
Are beans salt tolerant?
Common bean is sensitive to salinity, an increasingly severe agricultural problem in arid and semiarid regions (Shannon, 1986). Like many other leguminous crops, common beans suffer reduced yield even if it is grown at soil salinity less than 2 dS m–1 (Mass and Hoffman, 1977).
What crops are sensitive to salt?
Leaf damage
| Sensitivity | Chloride (mg/L) | Affected crop |
|---|---|---|
| Sensitive | <178 | Almond, apricot, citrus, plum |
| Moderately Sensitive | 178–355 | Capsicum, grape, potato, tomato |
| Moderately tolerant | 355–710 | Barley, cucumber, sweetcorn |
| Tolerant | >710 | Cauliflower, cotton, safflower, sesame, sorghum, sunflower |
Can beans grow in salt?
Crops differ in their tolerance to salts. So when you have salty water, crops that are tolerant to salt should be grown. Crops like beans, carrots, onions, capsicum should not be grown.
How does salt affect the growth of beans?
Agricultural production
If the level of salts in the soil water is too high, water may flow from the plant roots back into the soil. This results in dehydration of the plant, causing yield decline or even death of the plant. Crop yield losses may occur even though the effects of salinity may not be obvious.
What is the most salt-tolerant crop?
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.
Does salt water Help beans grow?
The long stems of the beans require water to act as a hydrostatic skeleton, adding salt to the water needed in the plant drives out the water causing the plant to dehydrate (Cook 2017).
Which vegetable is highly tolerant to salt?
Salt Tolerant Vegetable Plants
Plants having very high levels of tolerance and grow rapidly if given good care include: Beets. Kale. Asparagus.
Which vegetables are salt tolerant?
High Salt Tolerance
- Beets.
- Bell peppers.
- Broccoli.
- Cabbage.
- Kale.
- Loquats.
- Spinach.
- Tomatoes.
How much salt can a plant tolerate?
Most plants will typically suffer injury if sodium exceeds 70 milligrams per liter in water, or 5 percent in plant tissue, or 230 milligrams per liter in soil, in the extract from a saturated soil paste.
Are peas salt tolerant?
Pea is sensitive to salinity. Degree of salinity level affects rate of yield losses (Duke, 1981; Maas, 1986). In a study related to salt tolerance of two pea culti- vars, Cerda et al. (1982) concluded that one of the cultivar was classified as moderately salt-sensitive and the other as moderately salt-tolerant.
How much salinity can mung beans tolerate?
Most of the mungbean cultivars tolerate salt to an extent of 9–18 m mhos/cm than usual salt concentration of 5–6 m mhos/cm (at germination stage). Paliwal and Maliwal (1980) reported that mungbean seeds could tolerate 6 m mhos/cm salinity, compared to 3 m mhos/cm for black gram.
Is broccoli a salt tolerant?
Broccoli is considered a crop moderately tolerant to salt stress.
Does salt stop root growth?
They discovered that an inner layer of tissue in the branching roots that anchor the plant is sensitive to salt and activates a stress hormone, which stops root growth.
How do you neutralize salt in soil?
Chemical Remediation
Amending salty soils with sulfur, lime or calcium can help by removing or replacing the sodium in the soil. A soil test is needed to determine how much calcium, sulfur or lime to add. Sulfur amendments are used for soils that have free calcium carbonates.
How does salt affect seeds?
Salinity affects seed germination process through osmotic stress, ion-specific effects and oxidative stress, shown by decreasing germination rate and extended germination time [82]. Salinity increases external osmotic potential that reduces water uptake during imbibition [83].
Which crop is highly sensitive to soil salinity?
Carrot
What can grow in salty soil?
The best way to cope with a salty soil is to grow plants that tolerate it. Among leafy shrubs, the most tolerant plants include caragana, buffaloberry, silverberry, sea buckthorn, common lilac, golden currant, ‘Freedom’ honeysuckle and skunkbush sumac (Figs. 1–5).
Are potatoes salt tolerant?
Potato is an important cultivated crop species and since it is moderately salt sensitive there is a need to develop more salt tolerant cultivars. A high activity of Na+ transport across the tonoplast in exchange for H+ is essential to reduce Na+ toxicity.
Is salty water bad for plants?
Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients such as potassium and phosphorus, leading to deficiencies.
Is salt harmful for plants?
Salts absorb and bind tightly with water, preventing roots from absorbing water. The salt can even pull water from the plant, creating a drought-like condition. At higher concentrations, sodium will compromise the absorption of essential nutrients such as calcium, magnesium, and potassium.
