The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

BACKGROUND The aim of the study was to study the clinical effects of ozonated water on periodontal tissues. MATERIALS & METHODS In the present study 30 subjects were selected with age ranging from 20 to 60 yearsand pocket depth of ≥5mm. Two sites were selected in each patient whichwere divided into two groups. Group 1(control group-irrigation with saline) and Group 2(study group-irrigation wi...

Sources and mechanisms of nutrient transport in lawn irrigation driven surface runoff are largely unknown. We investigated the transport of nitrogen (N) and phosphorus (P) in lawn irrigation driven surface runoff from a residential neighborhood (28 ha) of 56% impervious and 44% pervious areas. Pervious areas encompassing turfgrass (lawns) in the neighborhood were irrigated with the reclaimed wa...

In this developing world, saving water is the main problem for agricultural sciences. So, in field, scientists are using many methods to save water-for instance, traditional irrigation, drip sprinkler sub-irrigation, and others. Solving irrigation problems article demonstrated sub-irrigation method agriculture plants Uzbekistan regions. According watering theory field condition compared region,...

in this study, effect of irrigation duration on concentration of some macro and micro nutrient elements in ‘thompson navel’ orange leaves grafted on three rootstocks was evaluated as a factorial experiment in completely randomized block design. factors included rootstocks in three levels (poncirus trifoliata, citrus aurantium and troyer citrange (citrus sinensis ´ poncitus trifoliata)) and irri...

The aim of this study was to evaluate the effectiveness of different irrigation solutions at different time intervals for the elimination of E. faecalis and C. albicans penetrated into the dentine tubules of primary and permanent teeth in vitro. The 4 mm primary and permanent teeth sections were sterilized and contaminated with a mixture of E. faecalis and C. albicans strains. After the applica...

OBJECTIVE To evaluate hemodynamic effects of intraocular epinephrine irrigation in patients undergoing cataract surgery. MATERIALS AND METHODS This study was conducted as a prospective double blinded clinical trial at the Shahid Sadoughi University of Medical Sciences, Yazd, Iran. Eighty-eight patients of age 38-90 years undergoing were randomly allocated into two groups: Group E received int...

The influence of different levels of irrigation and of variation in atmospheric vapour pressure deficit (VPD) on the synthesis, metabolism, and transport of abscisic acid (ABA) and the effects on stomatal conductance were examined in field-grown Cabernet Sauvignon grapevines. Xylem sap, leaf tissue, and root tissue were collected at regular intervals during two seasons in conjunction with measu...

the water deficiency is one of the serious problems in the arid zones. in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted using three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), irrigation of three levels (irrigated at 5, 10 and 15 days intervals) and tow olive cultivars (ma...
