abstract due to limited water resources in agriculture, application of each strategy to economize water use and increase area under cultivation is very important. one such strategy is deficit irrigation. for optimal planning of deficit irrigation, it is necessary to determine different sensitive stages of plant water shortages. in this study the effect of deficit irrigation on growth and yield ...

Nonflooded irrigation is an important water-saving rice cultivation technology, but little is known on its photosynthetic mechanism. The aims of this work were to investigate photosynthetic characteristics of rice during grain filling stage under three nonflooded irrigation treatments: furrow irrigation with plastic mulching (FIM), furrow irrigation with nonmulching (FIN), and drip irrigation w...

salinity stress is one of the most important environmental constraints that have been limited agricultural production in iran. therefore, introducing suitable cultivars having desirable yield under salinity stress will lead to increase of production efficiency. in order to study the response of spring safflower cultivars to salinity, an experiment was carried out at the experimental station of ...

in order to evaluate the effects of sub soiling and irrigation level treatments on yield of sugar beet and wheat in rotation, an experiment was conducted at agricultural research station ofwest azerbaijanprovince. the plots were arranged as a strip plot experiment in randomized complete block design with three replications. horizontal plot (sub soiling treatment) consisted of sub soiling depth ...

to investigate the effect of deficit irrigation and macro and micro fertilizers on morpho-physiological characteristics of satureja a field experiment was conducted in agricultural research station of haji-abad (hormozghan province-iran) a split plot randomized complete block design with three replications during the growing season of 2012-2014. irrigation treatments consisted of normal, modera...

abstract the irrigation water quality is not suitable for crop production in most regions of iran. it is estimated that almost six bcm/year of saline water enter to the rivers, in iran. the saline water can potentially use for growing of tolerant crops with a specific management on the agriculture practice. one of the management methods is the conjunction use of fresh and saline water. in this ...

water stress decrease water content and water potential between soil and root. therefore, water potential  of plant declines and plant faces with water stress. water stress in different stages of growth can be useful in different aspects. water stress can be practiced from two point of view, increasing water use efficiency (wue) and improving cultural practices. no irrigation in insensitive sta...
