The experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in Kabootatabad of Esfahan farm. An experiment was conducted in split plot and was designed in randomized complete block with three replications. Irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...

In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...

increasing the water use efficiency in crop production is an important issue today. an experiment was conducted in 2009 in order to evaluate the corn reaction to partial root zone drying at fars province. treatments consisted of four irrigation levels (control, alternative furrow irrigation during whole season, alternative furrow irrigation until flowering then full irrigation and full irrigati...

Aim: To clinically evaluate the effect of different irrigation activation techniques (needle irrigation, passive ultrasonic (PUI) and EndoVac) on post-operative pain after single-visit endodontic treatment. Materials methods: Thirty patients aged between 16 40 years requiring therapy asymptomatic vital/non vital maxillary central or canine teeth were selected for this study. In all cases, root ...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

The disposal of untreated urban sewage in to open water bodies is common in most developing countries. This poses potential negative consequences to public health and agricultural sustainability. Hyderabad, one of India’s largest cities, disposes large amounts of its wastewater untreated into the Musi River, from where it is used, with the aid of irrigation weirs, for agricultural production. T...

proper management of saline soils needs adequate information about the amount and salt distribution in the root zone. irrigation is one of the factors that control the distribution of salt. this study investigated soil leaching simulation by using hydrus2d software based on the evaporation of soil surface of a land without plant located at shahid chamran university, ahwaz, iran. samples were ta...

Drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. To evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. Cultivars with two-level white seedless and khosh...
