in order to study the effects of pgpr application methods on essential oil percent and yield of lavender (lavandula angustifolia l.) under drought stress conditions an experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experi...

Mediterranean temporary ponds on Doñana’s aeolian sands form an extensive system of small dynamic water bodies, dependent on precipitation and groundwater, of considerable importance for biodiversity conservation. Different areas of the aeolian sands have received different levels of environmental protection since 1969, and this has influenced the degree of conservation and the flooding dynamic...

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 past couple of decades, there is immediate growth in field of agricultural technology. Utilization of proper method of irrigation by drip is very reasonable and proficient. A various drip irrigation methods have been proposed, but they have been found to be very luxurious and dense to use. The farmer has to maintain watch on irrigation schedule in the conventional drip irrigation system, whi...

Over the past few decades, the competition for freshwater resources has substantially increased in arid/semi-arid areas, exacerbating the pressure on the largest user of water, namely agriculture, to consume less water. However, reducing crop consumptive water use or evapotranspiration through water stress can have a negative impact on production economics if not precisely managed. Remote sensi...

A fuzzy control irrigation system for cotton field is presented in this paper. The system is composed of host computer, slave computer controller, communication module, soil water sensors, valve controllers, and system software. A fuzzy control model is constructed to control the irrigation time and irrigation quantity for cotton filed. According to the water-required rules of different cotton ...

The article presents the results of experimental research on influence micro-irrigation system designs water regime, productivity, and efficiency sunflower cultivation. Based this, main economic parameters agrotechnologies cultivation were calculated. Short-term field was carried out in period 2020-2022 lands Brylivske Institute Water Problems Reclamation National Academy Agrarian Sciences (Khe...

Partial leaf shedding induced by hydraulic failure under prolonged drought can prevent excess water consumption, resulting in delayed recovery of carbon productivity following rainfall. To understand the manner of water use of invasive species in oceanic island forests under a fluctuating water regime, leaf shedding, multiple physiological traits, and the progress of embolism in the stem xylem ...

Reuse of partially treated domestic wastewater for agricultural irrigation is a growing practice in arid regions throughout the world. A field sampling campaign to determine bioaerosol concentration, culturability, and identity at various wind speeds was conducted at a flooded wastewater irrigation site in Mexicali, Baja California, Mexico. Direct fluorescent microscopy measurements for total a...
