Salinization of agricultural areas due to intensive practices and irrigation is an important feature limiting crop yield and productivity. Inhibition of plant growth and even plant death by salinity is due to a reduction in water availability, sodium ion accumulation and mineral imbalances. In this context, ROS will be produced in both SALT STRESS AND GLUTATHIONE-DEPENDENT ENZYME ACTIVITIES IN ...

The fresh water shortage in agriculture is an increasing problem worldwide, therefore the possibility of cultivating crops under saline conditions is of high importance. Crithmum maritimum, a halophytic plant naturally found on the rocky coastlines of the Atlantic Ocean and the Mediterranean Sea, has a long history of human consumption and was recently suggested as a cash crop for biosaline agr...

Crop coefficients (Kc) are important for the development of irrigation schedules, but few studies on Kc focus on saline soils. To propose the growth-stage-specific Kc values for sunflowers in saline soils, a two-year micro-plot experiment was conducted in Yichang Experimental Station, Hetao Irrigation District. Four salinity levels including non-salinized (ECe = 3.4–4.1 dS·m–1), low (ECe = 5.5–...

To identify the causes of salinization and arsenic contamination of surface water on an embanked island (i.e., polder) in the tidal delta plain of SW Bangladesh we collected and analyzed water samples in the dry (May) and wet (October) seasons in 2012-2013. Samples were collected from rice paddies (wet season), saltwater ponds used for brine shrimp aquaculture (dry season), freshwater ponds and...

The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent...

The water salinity of the Euphrates River as it enters Iraq, expressed as total dissolved solids (TDS), has more than doubled compared to that of 1973. Downstream of Al Hindia Barrage, south of Baghdad, the salinity has increased gradually over the last 30 years. The annual average TDS at Al Nassiriah, in the lower reaches of the Euphrates, has increased from 1,080 ppm in 1979 to more than 4,50...

abstract mango is one of the most important tropical fruits in iran and salinity is an important problem to mango production in ‘hormozgan’ province and other mango growing areas in iran. at present experiment the effects of saline irrigation water of different sodium chloride concentration on vegetative growth and ion content of mango was evaluated. treatments comprised two type of cultivars (...

a greenhouse experiment was conducted during the growing seasons (2008/2009 and 2009/2010) to investigate the effects of water quality and soil amendments, irrigation methods and rates on tomato (solanum lycopersicon l. cv. red gold) yield and water use efficiency (wue). irrigation management treatments were fresh (0.86 ds m-1) and saline waters (3.6 ds m-1), surface and subsurface irrigation m...

abstract:background and objectives:in arid and semi-arid regions, salinity is a serious and chronic problem for agriculture. due to the improved methods of irrigation and mechanization this methods to increase water use efficiency and enhance the uniformity of water distribution in the field, is very important. main area of farming cotton in iran is about 150000 ha, which in kerman province mos...
