this study was conducted to determine the possibility of a crop water stress index (cwsi) to schedule irrigation for pistachio tree under subsurface drip irrigation. the effects of two irrigation intervals consisting 3 (i3) and 14 (i14) days based on measuring soil water content were investigated on the cwsi. from 22 may (doy 143) to 22 september (doy 266), the evapotranspiration in i3 and i14 ...
The research on reducing the water consumption in conventional cropping system is one of the important strategies to improve the water use efficiency in agriculture. In order to investigate the effect of time of potassium application under different irrigation regimes on millet grain yield and protein percent, a field experiment was carried out in Agricultural Research Center of Yasuj, Iran, in...
To design cost-effective and efficient drip irrigation systems, it is necessary to know the vertical and horizontal advance of the wetting front under the point source; also, the proper management of drip irrigation systems requires an awareness of the soil water distribution. Many factors influence wetting pattern dimensions, including discharge, land slope, irrigation time and soil texture. T...
STUDY OBJECTIVE Local nasal hyperthermia or inhalation of heated water vapor is often recommended as a home remedy for various rhinitis disorders such as the common cold and allergic rhinitis. Inhaled heated vapor treatments and simple saline solution nasal irrigation were investigated for their effect on inflammatory mediator production in nasal secretions. DESIGN Three treatments were given...
The hydrodynamic behavior of two annual legumes (Trifolium angustifolium L. and Onobrychis caput-galli (L.) Lam.) under water shortage was studied in a rain shelter experiment. Seeds were collected from natural grasslands of northern Greece and were sown in pots. Two months after seedlings' emergence, full irrigation (up to field capacity) and limited irrigation (40% of field capacity) were app...
The optimal management of prolonged priapism for patients with sickle cell anemia (SCA) has not been established. We prospectively studied in an outpatient setting the efficacy and safety of a procedure that employs aspiration of blood from the corpora cavernosa and irrigation with a dilute epinephrine solution under local anesthesia to relieve priapism in young patients with SCA. If hydration ...
Effect of change from the conventional (flooding) to subsurface irrigation system was studied on mature pistachio trees (Cultivar Ohadi) in Kerman pistachio research station for four years. This experiment was carried out in a randomized complete block design including 7 treatments and 3 replications. The experiment also used two irrigation intervals (7&14 days) and three water rates accordin...
Three test-plot series have been performed to gather information on runoff of sulfonamides from manured arable and grassland after sprinkler irrigation. To prepare test slurries with defined aged residues, liquid bovine manure was fortified with sulfadiazine, sulfadimidine, and sulfamethoxazole and stored short-term. After test-slurry application, the arable land was treated by soil cultivation...

In irrigation scheduling, one question is “how much is the optimal depth?”. In this study the optimal irrigation depth (by assuming the power distribution function and by taking into consideration the distribution function, which governs the data (normal distribution)) by considering the environmental effects was determined for three water management strategies (i. e. unlimited, limited nitroge...
