In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...

Knowing and applying the basic management functions of planning, organizing, staffing, directing, and controlling, as well as their permutations and combinations, are vital to effective delivery of public health services. Presently, graduate programs that prepare public health professionals neither emphasize teaching management theory, nor its application. This deficit puts those who become man...

Deficit irrigation or intentional under-irrigation offers the potential for sustainable water resources management. The DSSAT CERES-Maize and AquaCrop models were coupled to simulate effects of deficit on corn yield productivity. calibrated validated using observed values crop biomass under 40%, 50%, 60%, 70%, 80% depletion available soil water. Model simulation results showed that a 15% level ...

Water deficit is one of the most important difficulties, in which happes in dry zone and half dry zones.Water deficit, as the determinative factor, determinates the growing and extension of the plant cover inthese areas. Using the supper attractive, may reduce the production in the crops and control the plantcover in face of dry stress and water deficit. In this paper, the effect of supper attr...

wild jujube, ziziphus lotus, is a multipurpose xerophytic shrub of the rhamnaceae family widely distributed in arid and semi-arid regions of tunisia, where it occupies most soil types. the fruit is the edible part of the plant by local population. the reintroduction of this shrub requires the control of its multiplication in response to water shortage. this study aims to evaluate growth and wat...

in order to study the effect of water deficit effects on agronomic characteristics of sunflower ‎hybrids, three separate experiments were conducted as‏ ‏randomized complete block design with ‎three replications at the research field of seed and plant improvement institute - karaj. the first ‎experiment conducted at optimum conditions and plants were irrigated after 60 mm evaporation ‎from evapo...

Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...

BACKGROUND A large proportion of vineyards are located in regions with seasonal drought (e.g. Mediterranean-type climates) where soil and atmospheric water deficits, together with high temperatures, exert large constraints on yield and quality. The increasing demand for vineyard irrigation requires an improvement in the efficiency of water use. Deficit irrigation has emerged as a potential stra...
