Soil salinity is one of the main problems for plant growth in agriculture, especially in countries where crops should be irrigated (Ahloowalia et al., 2004). Soil salinity has been considered a limiting factor to crop production in arid and semi arid regions of the world (Munns, 2002). Saline soils are estimated about 5 – 10% of the world’s arable land (Szabolcs, 1994), and the area affected by...

Due to its low permeability, a clay liner is the main material used in solid waste disposal landfills. It is exposed there to various chemical, biological, and physical events, and the clay liner is affected by the resulting leachate. For this reason, when attempting to define the geotechnical characteristics of clay liners, the use of distilled water or tap water is far from being representati...

Abstract The aim of this study was to identify stable rice genotypes tolerant a salt stress environment and ideal mega-environments using AMMI (additive main effects multiplicative interaction) stability model analysis. A total 13 three tolerance checks were evaluated across locations (alkaline saline) for the two kharif seasons 2014 2015. Genotype CSR 36 (CHK3) found be most those tested. Geno...

Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under saline soils is preferred. In this study 15 wheat (Triticum aestivum L.) cultivars were used to investigate the effects of three salinity concentrations including 4, 8 and ...

Salinity does not only stress plants but also challenges human life and the economy by posing severe constraints upon agriculture. To understand salt adaptation strategies of plants, it is central to extend agricultural production to salt-affected soils. Despite high impact and intensive research, it has been difficult to dissect the plant responses to salt stress and to define the decisive key...

BACKGROUND Globally, about 20% of cultivated land is now affected by salinity. Salt tolerance is a trait of importance to all crops in saline soils. Previous efforts to improve salt tolerance in crop plants have met with only limited success. Bacteria of the genus Deinococcus are known for their ability to survive highly stressful conditions, and therefore possess a unique pool of genes conferr...

background and objectives: primary and secondary soil salinity is one of the main reasons of land degradation and desertification in arid and semi-arid zones. change detection of salt-affected soils, aides finding salt distribution and salinization trends. present study was arranged for monitoring soil salinity status of agricultural lands located on southern part of bakhtegan lake in fars prov...

The salinization of land is a major factor limiting crop production worldwide. Halophytes adapted to high levels of salinity are likely to possess useful genes for improving crop tolerance to salt stress. In addition, halophytes could provide a food source on marginal lands. However, despite halophytes being salt-tolerant plants, the seeds of several halophytic species will not germinate on sal...

Soil aggregate stability is an ideal integrative soil quality indicator, but little known about the relevance of such indicator with depth for salt-affected soils. The objective this study was to determine and identify preponderant aggregation factors, both in topsoil subsoil horizons conditions. We conducted field investigations by describing profiles pedological pits collecting samples from d...

Salt contamination of soils due to climate change faces a severe environmental issue that affects crop production today. However, the response mechanism in plants salt stress is not fully understood. The present study investigated molecular and biochemical changes under rice seedlings three cultivars, i.e., AGPPS114 (salt-tolerant), OM6967 (moderately tolerance), VD20 (salt-sensitive). Increasi...
