in order to evaluate the effects of drought and salinity stresses on growth parameters and essential oil of lemon balm, two experiments with three replications in a randomized complete block design were applied. five levels of salinity including zero, one, two, three and four ds/m of sodium chloride solution, and five drought stress treatments including 50, 62.5, 75, 87.5 and 100% as available ...

this research was conducted in order to study the effect of climate and geology factors on groundwater sources in mahvelat plain. in order to study the groundwater quality and quantity considering groundwater resources including wells and qanats; using groundwater surface, electric conduction (ec) and the total density solution (tds), the maps of groundwater surface fluctuation and quality para...

trifolium spp. are native plants in iran exhibiting good ground cover po-tential. salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. the main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...

background and objectives: infunction of the photosynthetic apparatus of halophytes plays an important role in their salinity tolerance. kochia as a halophyte, is of high ability in biomass production in salinity stress conditions. thus study photosynthesis and the related factors salinity stress can provide appropriate physiological view for better understanding of the plant mechanisms of in s...

salinity is one of the most limitation factors for crop production in agricultural systems due to the toxic effects and preventing water and nutrients absorption, in this research the efficiency of four strains of fluorescent pseudomonads on concentration of nutrient elements in rice was determined, under saline conditions. a pot experiment was carried out based on the factorial completely rand...

Around the world, especially in semi-arid regions, millions of hectares of irrigated agricultural land are abandoned each year because of the adverse effects of irrigation, mainly secondary salinity and sodicity. Accurate information about the extent, magnitude, and spatial distribution of salinity and sodicity will help create sustainable development of agricultural resources. In Morocco, sout...

In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
