“…Soil salinity has detrimental effects on seed germination and plant growth (Bernstein 1962;Garg and Gupta 1997;Ramoliya, Patel, and Pandey 2006;Patel and Pandey 2008;Patel, Jadeja, and Pandey 2010). However, plant species differ in their sensitivity or tolerance to salts (Marschner 1995).…”

Greenhouse experiments in a completely randomized block design were conducted to assess the effect of soil salinity on emergence, growth, water status, proline content, and mineral accumulation of seedlings of Tamarindus indica Linn. (Caesalpiniaceae). Sodium chloride (NaCl) was added to the soil, and the salinity was maintained at 0.2, 3.9, 6.2, 8.1, 10.0, 11.9, and 13.9 dS m −1 . Salinity lowered water content and water potential of tissues, which resulted in an internal water deficit to plants. Consequently, seedling growth significantly decreased and proline content in tissues increased as salinity increased. There were no effective mechanisms to control net uptake of sodium (Na + ) and its transport to shoot. Potassium (K) and calcium (Ca) contents in tissues significantly decreased, while nitrogen (N) content significantly increased as salinity increased. Changes in tissues and whole-plant accumulation patterns of other nutrients, as well as possible mechanisms for avoidance of Na + toxicity in this species in response to salinity, are discussed.

-Greenhouse experiments were conducted to assess the effects of supplemental Ca 2+ in salinised soil on germination and plant growth response of castor plant (Ricinus communis L. Var. Avani-31, Euphorbiaceae). NaCl amounting to 390 g was thoroughly mixed with soil of seven lots, of 100 kg each, to give electrical conductivity of 4.1 dS m -1 . Further, Ca(NO 3 ) 2 × 4H 2 0 to the quantity of 97.5, 195, 292.5, 390, 487.5, and 585 g was separately mixed with soil of six lots to give 1:0.25, 1:0.50, 1:0.75, 1:1, 1:1.25, and 1:1.50 Na + /Ca 2+ ratios, respectively. The soil of the seventh lot contained only NaCl and its Na + /Ca 2+ ratio was 1:0. Soil without addition of NaCl and Ca (NO 3 ) 2 × 4H 2 0 served as control, with a 0:0 Na + /Ca 2+ ratio. Salinity significantly retarded seed germination and plant growth, but the deleterious effects of NaCl on seed germination were ameliorated and plant growth was restored with Ca 2+ supply at the critical level (1:0.25 Na + /Ca 2+ ratio) to salinised soil. Supply of Ca 2+ above the critical level further retarded seed germination and plant growth due to the increased soil salinity. Salt stress reduced N, P, K + and Ca 2+ content in plant tissues, but these nutrients were restored by addition of Ca 2+ at the critical level to saline soil. In contrast, Na + content in plant tissues significantly increased in response to salinity, but significantly decreased with increasing Ca 2+ supply to saline soil. The results are discussed in terms of the beneficial effects of Ca 2+ supply on the plant growth of Ricinus communis grown under saline conditions.

“…Coastal soils are often at high risk of salinization because either they are fed by tidal water or irrigation with saline water results in salt concentrations built up over time because of evaporation. Plenty of information is available on the effects of salinity on the physical and chemical characteristics of soil (Ramoliya et al 2006;Patel and Pandey 2007;Patel et al 2010); however, soil microbial activity in saline soils is scantily studied. Soil microbial communities and their activities are significantly affected by salinity (Pankhurst et al 2001;Baumann and Marschner 2013) which are known to alter by biotic and abiotic stresses.…”

“…In addition to salt-induced water stress, saltstressed plants also experience negative effects on growth and development due to nutrient imbalance and ion toxicity (Hardikar et al 2011). The uptake of nutrient by plants has been frequently studied under saline soil conditions (Patel and Pandey 2007;Patel et al 2010;Hardikar et al 2011), but the relationship between uptake of plant nutrient and soil salinity is rather multifaceted and remains poorly understood (Tozlu et al 2000). An investigation of growth and nutrient uptake of plants by seawater irrigation can provide insights into the mechanisms that plants are tolerant of salt stress.…”

Irrigation with diluted seawater would be an alternative water resource which can play an important role under scarce resources of freshwater for promoting agricultural production in coastal areas. Salvadora persica Linn. was irrigated with different concentrations of seawater (0, 10, 20, 40, 60, 80 and 100 % seawater), and their effect on plant growth, nutrient contents in soil and plants, shift in soil microbial community structure (phospholipid fatty acid; PLFA) and community-level physiological profiling (CLPP, Biolog ECO MicroPlate) were studied. Plant dry matter was significantly increased with all seawater treatments, and highest increase was at 20 % seawater treatment. Sodium and chloride contents were significantly increased, whereas ratios of K/Na and Ca/Na were significantly decreased in plants with seawater irrigation. Soil electrical conductivity (EC), available K and Na were significantly increased with increasing the concentration of seawater. Total PLFA concentration and PLFA profile of soils were used as indices of total microbial biomass and community composition, respectively. The concentrations of total PLFA, gram-positive, gram-negative and actinomycetes biomarker PLFAs were significantly reduced at 20, 40, 80 and 40 % concentrations of seawater, respectively. The application of different concentrations of seawater induced a clear shift in the soil microbial community structure toward the bacterial abundance. The microbial community structure and community-level physiological profiling in seawater irrigation treatments had significantly differentiated. It can be concluded that irrigation with different concentrations of seawater had significant impact on soil chemical and microbial properties which is attributed due to the salinity stress.
