“…Growth response of upland rice cultivar Inpari-34 was in accordance with growth of some rice genotype in solution at 8 dS/m at 7 days when their fresh and dry weight as well as shoot heights were reduced [22]. Damage of rice plant in saline soil in controlled conditions caused by osmotic imbalance and accumulation of chloride ion was reported ( [22]. Plant growth inhibition due to excessive sodium (Na2+) uptake; causes Na ions to be absorbed enormously by plants [23].…”

Saline soil in general has low nitrogen (N) availability and restricted N uptake. Application of manure and nitrogen fixing bacteria (NFB) in addition to inorganic fertilizer are needed but manure amendment on soil will contribute to increase antibiotic residue in soil. A pot experiment has been conducted to verify the effect of antibiotic-resistance NFB Azotobacter on nitrogen availability and growth of rice seedling in saline soil contaminated with tetracycline and ampicillin. Green house experiment was arranged in factorial Randomized Block Design to examine four concentrations of Azotobacter sp. liquid culture and two kind of generic antibiotic. The first factor was without and with 106 , 107, and 108 CFU g-1 of Azotobacter inoculation, and the second one were antibiotic treatment consisted of tetracycline and ampicillin applied at 1 mg/kg. The results showed that neither Azotobacter nor antibiotic affected plant height, soil pH and EC, as well as Azotobacter population in rice rhizosphere. The interaction effect on both treatment was significant on total nitrogen in soil. This research suggested that Azotobacter maintained soil N when inoculated to soil up to 106 CFU/g and 108 CFU/g irrespective of antibiotic contamination but the bacteria had not yet affect growth of rice seedling in high sodium soil.

“…For dicots, Matejovic and Durackova (1994) compared several dry and wet digestions methods for Alfalfa and found no differences in Na and K concentrations when using different extraction methods, which was confirmed our study with sweet potato (Figure 6). Digestion and extraction of ions with HCl generally produced higher values for K than all other methods (Figures 3, 4, and 6); thus, it is important to know which extraction method was used when directly comparing K results across studies (Gholizadeh & Navabpour, 2011).…”

Background and aims Determination of sodium (Na), potassium (K), and chloride (Cl) content in plant tissue is required for research related to salinity resistance in plants. Standard methods are available to extract these elements from dried plant material, but these methods are often costly, relatively dangerous, or time consuming. Many authors modify extraction methods substantially without proof of comparability across methods. Methods Here, dried tissues of two varieties of rice and three varieties of sweet potato subjected to salt stress were extracted for Na and K using six different extraction methods (1–6) and for Cl using three Cl‐free extraction methods (2, 4, 5) for Cl: (1) the VDLUFA standard method, consisting of ashing, and heat extraction in hydrochloric acid (HCl), (2) hot water pressure extraction via autoclave, (3) extraction with 1 M HCl overnight, (4) hot water extraction at 90°C for 1 h, (5) acetic acid extraction in hot 1 M acetic acid for 2 h, and (6) extraction with a microwave using nitric acid. Na and K were determined via flame photometer and Cl via automated flow analysis. Results Na and K concentrations varied little among different extraction methods as compared to the VDLUFA standard method, and for Cl, all extractions resulted in similar tissue Cl concentrations. Conclusions Ultimately, the choice of extraction method depends on the instrumentation and lab equipment necessary, available budget, the available amount of sample, and time constraints which should be decided according to the experiment. For reasons of comparability among publications, methods applied should be clearly described since results vary depending on the method chosen.

“…Despite the yield gains of these improved varieties compared to susceptible varieties, the difference between the potential yields of these varieties under normal conditions and those obtained under stress conditions remains important (Awala et al 2010). In addition, at a relatively high salinity levels, the tolerance level of these varieties becomes low (Gholizadeh and Navabpour 2011). Under this situation, there is a need to develop management practice that would help to improve rice productivity under salinity stress.…”

Growing rice in saline soils by minimizing damage on growth and yield remains a challenge. We conducted field experiments in the Africa Rice research field located in the Senegal River delta (16°11ʹ N, 16°15ʹ W) to study the effects of three management options of fertilization e.g. (i) nitrogen, phosphorus, and potassium fertilization: NPK; (ii) NPK combined with zinc: NPK-Zn, and (iii) NPK combined with gypsum: NPKgypsum on the soil salinity level, the nutrient uptake and the productivity of different rice cultivars. The whole objective of this study is to determine how zinc or gypsum associated to NPK fertilizer can improve the growth and productivity of rice crop in saline soil. Results showed that the initial soil salinity level was reduced rapidly in plots treated with gypsum. The leaf-K/Na ratio, agronomic nitrogen use efficiency (ANUE), and grain yield of rice cultivars under the salinity stress were improved by the NPK-gypsum and NPK-Zn options relatively to the NPK option, suggesting that NPK-gypsum and NPK-Zn are suitable management options in reducing adverse effect of low K/Na, low ANUE as well as to improve rice yield under salinity stress.
