Background: Legumes are under explored crops in comparison to staple cereal crops and decreasing agricultural lands along with waste lands and poor water resources are the main constraints for sustainable agricultural production. Chickpea is the third most important food legume, known for its high nutritive values, generally considered as relatively salt sensitive crop. Existence of large genetic variation provides opportunity to explore variations and exploit the available salinity tolerance in chickpea. Methods: A Randomised block design experiment was conducted to explore the salinity tolerance in 10 chickpea genotypes including CSG-8962 (Karnal Chana-1), as salt tolerant check during 2018-19 and 2019-20 under control and salinity ECiw 6 dS/m and ECiw 9 dS/m. The leachate was collected from time to time to monitor the buildup of the desired salinity. At harvesting stage, yield and yield attributing traits were recorded and yield indices were calculated to identify the potential of chickpea genotypes against salinity stress.Result: Saline irrigation water significantly decreased the number of pods/plant by 21.29% under ECiw 6 dS/m and 53.29% under ECiw 9 dS/m. Genotypes ICCV 10, CSG 8962 and DCP 92-3 retained maximum number of filled pods at ECiw 6 dS/m, while under higher salinity of ECiw 9 dS/m, CSG 8962, ICCV 10 and KWR108 had the highest filled pods. Saline water of 6 dS/m caused reduction of 36.1% - 65.0% in grain yield, which further increased to 81.0% - 98.5% with saline water of 9 dS/m. Genotypes S7 and ICCV - 10 had percent grain yield reduction of 36.13% and 41.24% respectively whereas the salt tolerant check had a percent reduction of 46.94% at ECiw 6 dS/m. Based on studied yield indices, genotypes S7, KWR108 and CSG 8962 showed relatively higher tolerance than other studied genotypes, whereas BG 256 and ICC 4463 were the most salt sensitive chickpea genotypes.

Selection Indices

Soil salinity is one of the main factors limiting cereal productivity in worldwide agriculture. Exploitation of natural variation in local barley germplasm is an effective approach to overcome yield losses. Three gene pools of North African Hordeum vulgare L. grown in Tunisia, Algeria and Egypt were evaluated at the reproductive stage under control and saline conditions. Assessment of stress tolerance was monitored using morphological, yield-related traits and phenological parameters of reproductive organs showing significant genetic variation. High heritability and positive relationships were found suggesting that some traits associated with salt tolerance could be used as selection criteria. The phenotypic correlations revealed that vegetative traits including shoot biomass, tiller number and leaf number along with yield-related traits such as spike number, one spike dry weight, grain number/plant and grain number/spike were highly positively correlated with grain yield under saline conditions. Hence, these traits can be used as reliable selection criteria to improve barley grain yield. Keeping a higher shoot biomass and longer heading and maturity periods as well as privileged filling ability might contribute to higher grain production in barley and thus could be potential target traits in barley crop breeding toward improvement of salinity tolerance. Multiple selection indices revealed that salt tolerance trait index provided a better discrimination of barley landraces allowing selection of highly salt-tolerant and highly productive genotypes under severe salinity level. Effective evaluation of salt tolerance requires an integration of selection indices to successfully identify and characterize salt tolerant lines required for valuable exploitation in the management of salt-affected areas.

ABSTRACT Saline irrigation water at high levels causes disturbance in the growth of more sensitive plants. The objective of this research was to evaluate the initial growth of Pityrocarpa moniliformis seedlings under different electrical conductivity in irrigation water through physiological and biochemical analyses. The experiment was conducted in a greenhouse with five water electrical conductivities (0.5, 2.0, 4.0, 6.0 and 8.0 dS m-1) and four repetitions of 20 plants each, arranged in a randomized block design. Application of the treatments with irrigation water containing NaCl began at 30 days after sowing. To determine the behaviour of the species, the following variables were analysed: stem diameter, plant height, number of leaves, leaf area, Dickson quality index, shoot dry mass, root dry mass and total dry mass, as well as the biochemical variables, such as the concentrations of total soluble sugars, free proline and chlorophylls a and b. The increase in irrigation water salinity hampered the growth of P. moniliformis seedlings, with electrical conductivity of 0.5 dS m-1 being the limit for maximum production. The results also indicated that the deleterious effects of salt stress on P. moniliformis seedlings variables increase in concentrations of proline, total soluble sugars and betaine glycine.

A field experiment with split-split plot design (SSPD) was conducted to study the response of two winter wheat (Triticumaestivum L.) cultivars (viz. salt tolerant cultivar KRL-1-4 and salt non-tolerant cultivar HD-2894) under saline irrigation regimes with and without foliar potassium fertilization on growth and grain yield of wheat during rabi 2011-12 and 2012-13. Potassium in the ratio of K+: Na+ (1: 10) was applied as foliar application during the heading stage of the crop. Results showed that the grain yield of KRL-1-4 and HD-2894 cultivars with foliar potassium fertilization at the heading stage increased by 6.5 to 22% and 3 to 15% during rabi 2011-2012, respectively under different saline irrigation regimes as compared to the control. Moreover, the results of rabi 2012-13 showed an increase in grain yield ranging from 4.5 to 20% for KRL-1-4 as compared to the control. Statistical analysis of grain yield parameter showed that the foliar potassium application in both varieties resulted in significant yield difference at 0.05 probability level as compared to the non-foliar application. Overall, it was observed that the foliar potassium fertilization increased the grain yield of both wheat cultivars, while the salt tolerant cultivar performed better than the salt non-tolerant cultivar under irrigated saline regimes.

Saline irrigation water is becoming an important water source as fresh water is fast becoming a scarce resource in many areas of the world, including Eswatini, especially in arid and semi-arid regions.  A study to test the response of two varieties of spinach (fordhook giant and mustard) to salinity was conducted in a field pot experiment at the Faculty of Agriculture at the Luyengo Campus of the University of Eswatini.  The treatments were laid in a randomized block design (RCBD).  The experiment consisted of four treatments, each replicated twelve times.  Treatments were salinity levels of 0.0 dS/m, 1.5 dS/m, 2.0 dS/m and 3.5 dS/m.  All the treatments were subjected to similar agronomic practices. Spinach was grown and observed for a period of five weeks.  Plant height was measured and the number of leaves counted weekly throughout the experiment. Significant differences (P < 0.05) between salinity treatments were obtained for plant height beginning in week 2 but were more pronounced in week 3, 4 and week 5.  No significant differences were obtained for the number of leaves.  There were however, clear significant differences between spinach irrigated with none saline irrigation water compared to saline irrigation water.   It was concluded that irrigating spinach with saline water of more than 2.0 dS/m drastically reduce plant growth but not the number of leaves under the conditions of the experiment.

Globe artichokes recently have been planted in the irrigated desert area of southern California. Soils in this area are, or have the potential to become, highly saline from the application of saline irrigation water. Thus, a 2-year field plot study was conducted. A control and five saline treatments were imposed by irrigation with waters that contained equal weights of NaCl and CaCl. Bud yield and vegetative growth were measured. For the two years, relative bud yield was unaffected up to a soil salinity of 6.1 dS·m [electrical conductivity of the saturated soil extract (EC,)]. Each unit increase in salinity above 6.1 dS·m reduced yield by 11.5%. These results place artichoke in the moderately salt-tolerant category. Yield reduction was attributed primarily to reduced bud weight rather than bud count. Vegetative growth was more tolerant to salt stress than was bud production. Chloride concentration in midrib and blade tissue increased as salinity increased.

Physiological Evaluation

This study was conducted to assess the effect of soil salinity on leaf area (LA), the number of days to flowering (DF), plant height (PH), and grain yield. Overall, 60 wheat genotypes were used, including 49 CIMMYT elite lines and 11 commercially grown Egyptian wheat cultivars. During two growing seasons (2017 and 2018), the genotypes were grown in non-saline (S0) and saline (S1) soils. A randomized complete block design with three replicates was used in a split-plot arrangement. Salinity levels were randomly assigned to the main plots, while genotypes were randomly assigned to the subplots. The obtained results showed that the saline soil adversely affected the evaluated genotypes. Furthermore, a highly significant effect of genotypes × salinity was observed on grain yield and its attributed traits. Based on salinity indices results, some of the imported wheat genotypes outperformed the Egyptian cultivars in grain yield under salinity stress conditions. The results further indicated that Sakha-93, C-31, and C-40 were the most salt-tolerant genotypes. The best performing line among the CIMMYT lines was C-31, which recorded the highest grain yield under none-saline and saline soil in the two seasons of study.

The goal of this study is to assess the use of saline groundwater in combination with soil amendments to increase the efficiency of wheat production in new agricultural soil in Egypt. The experiment was conducted during the two consecutive growing seasons, 2019/2020 and 2020/2021, at the Shandaweel Agricultural Research Station, Sohag, Egypt. In this study, plants of Shandaweel 1 spring bread wheat cultivar were grown under the combinations of the two water treatments, i.e., freshwater (307.2 ppm) and saline water (3000 ppm (NaCl + MgCl2)) representing groundwater in Egypt delivered by drip irrigation and the two biochar rates, i.e., zero and 4.8 ton/ha as a soil amendment. The cob corn biochar (CCB) was synthesized by using the slow pyrolysis process (one hour at 350 °C). The results revealed that saline water reduced the grain yield ratio by 8.5%, 11.0%, and 9.7% compared to non-saline water during seasons 2019/2020 and 2020/2021 and over seasons, respectively. Concerning, combined over seasons, the biochar addition enhanced the grain yield by 5.6% and 13.8% compared to non-biochar addition under fresh and saline irrigation water conditions, respectively. Thus, the results indicated and led to a preliminary recommendation that saline groundwater is a viable source of irrigation water and that biochar seemed to alleviate salinity stress on wheat production and in reclaimed soils of Egypt.

Abstract The present study was conducted to investigate the response of major cereal crops to application of potassium with balanced fertilizers as well as to validate newly released soil fertility map of Amhara Region. A field experiment was carried out with different districts of North Shewa of Amhara region: Kewet (Sorghum), Basona warana (Food Barley) Moretena jiru and Mojana wedera (Bread wheat. A randomized complete block design was used, with three replications. The treatments were consisted of NPS, NPS+K, NPSBZn, and NPSBZn+K. The required amount of nitrogen and phosphorus were adjusted to crop and site specific recommendation. The rate of K was 150 kg ha-1 K2O and applied as a straight fertilizer at planting in the form of potassium chloride (KCl).The highest grain yield of sorghum (4301.9 kg ha-1) was recorded under the treatment of NPSBZn and followed by NPS fertilizer application respectively, while lower grain yields (3017.7 and 3186.9 kg ha-1) were recorded under the treatments of NPSBZn and NPS with potassium fertilizer application. Even though statically insignificance both NPS and NPSBZn, application of NPSBZn had gave 5.3% of sorghum grain yield advantage as compared to sole NPS and N fertilizer application. The highest grain yield of barley (4411 kg ha-1) also was recorded under the treatment of NPS and followed by NPS+K respectively, while lower grain yield (3960.6 kg ha-1) was recorded under the treatments of NPSBZn. Grain yield of bread also showed similar trend as grain yield of food barley at Moretena jiru and Mojana wedera districts. Generally the results of this experiment did not showed agronomical viable options due to utilization of potassium with recommended NP nutrient sources and micronutrients. The soil was deficient in organic matter, total nitrogen, and available phosphorus and adequate in available potassium. Thus it can be concluded that potassium is not a yield limiting nutrient but soil nitrogen and phosphorus management need especial attention.

Nursery experiments were conducted in the Dominican Republic to determine the tolerance of tamarind (Tamarindus indica), acerola or Barbados cherry (Malpighia punicifolia), and zapote (Calocarpum sapota) irrigation with saline water (0, 2, 4, 6, and 8 dS/m) at different frequencies (every 24, 48, and 72 hours) during 60 days. Results indicate that tamarind was the less salt-sensitive and zapote the less salt-tolerant of the three species. Linear relationships were found between salt concentration and growth, with biomass accumulation decreasing as salinity and irrigation frequency increased.

Water quality and quantity are critical issues in the Southwest United States and many other locations in the world. Use of reclaimed water for landscape irrigation can conserve potable water significantly and possibly reduce fertilizer application. A potential concern of using alternative water sources is elevated salt levels, which can have adverse effects on plant growth and aesthetic appearance. Most Texas native wildflowers are known to be hardy and easy to maintain, and are drought tolerant after establishment. In addition, native wildflowers provide wildlife habitat and support native pollinators. However, little information is available on salinity tolerance of many Texas native wildflower species. In this study, two separate hydroponic experiments were conducted to determine salt tolerance of three Texas native wildflower species: Gaura villosa Torr. (wooly gaura), Xanthisma texanum DC. (Texas sleepy daisy), and Ipomopsis rubra (L.) Wherry (standing cypress). Species were suspended in a hydroponic setting using a randomized complete block design with a control [municipal reverse-osmosis (RO) water with a nutrition solution at an electrical conductivity (EC) of 3.0 dS·m–1] and three salinity treatments: 5.0, 7.0, and 11.0 dS·m–1 EC. Sixty days after salinity treatments were initiated, percent survival, visual rating, fresh weight, and length measurements were recorded on root and shoot tissue. To determine tissue percentage sodium (Na+), calcium (Ca2+), and chloride (Cl–), shoot and root tissues were dried and ground for tissue analysis. At the end of each experiment, total percent survival for X. texanum, G. villosa, and I. rubra were 100%, 94%, and 76%, respectively, with the greatest mortality rate at the highest salinity treatment. Shoot dry weight and plant growth index (PGI) decreased in all three species as salinity of irrigation water increased. Visual qualities of all species were mainly compromised at the highest salinity level. Ion concentrations in root and shoot tissues were affected by salinity levels and varied among species. Different mechanisms of salt tolerance (ion exclusion, salt excretion, and tissue tolerance to high concentrations of Na+ or Cl–) have been observed among wildflower species, and results indicate different salt tolerance mechanisms were exhibited by each trial species. In addition, results indicate I. rubra can be identified as moderately salt tolerant (EC up to 7.0 dS·m–1), whereas, X. texanum and G. villosa can be classified as salt tolerant (EC up to 11.0 dS·m–1). Results from this study suggest great potential of these native Texas wildflowers in landscapes using limited-quality irrigation water or landscapes with soil salinity concerns.
