Salinity stress is one of the most important problems of arid and semi-arid regions in the world. Based on Food and Agriculture Organization report, more than 40% of Iran’s under Irrigation lands, are against secondary salinity. The effects of salinity stress on some of vegetative traits and water relations on two rangeland plants species of leguminosae family was the main objective of this exp...

Rapid blight is a new disease of cool season turf grasses caused by Labyrinthula terrestris. It is problematic in Arizona and ten other states in cool season turfgrasses at sites with elevated salinity of soil and/or irrigation water. L. terrestris colonizes Tifgreen bermudagrasses in the field, but causes no apparent disease. Laboratory trials have shown that as concentrations of sodium chlori...

A greenhouse study was conducted to determine the effects of irrigation waters differing in salt composition on growth characteristics, salt ion and selenium (Se) accumulation, and distribution in plant components of the soybean (Glycine max L. Merr.) cultivar “Manokin.” Plants were grown in sand cultures and irrigated with isoosmotic solutions containing (1) Cl− as the dominant anion, or (2) a...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

Salinity of water irrigation and soil are of the major factors affecting plant growth and productivity worldwide. In this research the effects of salicylic acid on some morpho-physiological and biochemical characteristics of walnut (Juglans regia) seedlings under salinity stress condition were studied. The experiment was a two-factor factorial experiment arranged in completely randomized design...

Bagherzadeh A., Paymard P. (2015): Assessment of land capability for different irrigation systems by parametric and fuzzy approaches in the Mashhad Plain, northeast Iran. Soil & Water Res., 10: 90–98. Water quality and quantity in agricultural systems of arid and semiarid regions of the world are of great importance. In this regard the trend to pressurized irrigation systems compared to surface...
