This research examines the role of micro-irrigation systems, i.e., sprinkler and drip irrigation, on date palm production quality in a semi-arid region. The field experiment was carried out for two successful seasons at private farm, Al-Nubaria region Egypt. planted under pressurized irrigation (drip mini-sprinkler irrigation) to investigate effect both systems three water treatments (100, 80, ...

the importance of groundwater as a source of water supply in arid, semi –arid areas in recent years due to the uncontrolled exploitation of groundwater have been doubled. uncontrolled exploitation has been caused a drop in the water table in many areas of the country, including this region. with replace methods of modern irrigation instead of traditional irrigation methods can prevent drop the ...

BACKGROUND Soil application of systemic neonicotinoid insecticides can provide opportunities for long-term control of insect pests in vineyards, with minimal risk of pesticide drift or worker exposure. This study compared the effectiveness of neonicotinoid insecticides applied via irrigation injection on key early-season and mid-season insect pests of vineyards in the eastern United States. R...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

scarcity of irrigation water and decreasing of water resources with suitable quality are the most important limiting factors in the crop production in the most of countries such as iran . therefore research for optimum usage of water and economy in consume water is important policies for growing of production and  the selection of cultivars with less necessity of water can help to matter.so, an...

Gary A. Clark Research Agricultural Engineer Subsurface drip irrigation (SDI) systems deliver water to the root zone of crops using polyethylene drip tubing that is permanently buried below the soil surface. In properly designed and operated systems, little or no wetting of the soil surface occurs, nor is there visual evidence of the system performance. Because SDI systems apply water different...

water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...

Drip irrigation is the most water efficient system available to water garden. Some systems are so efficient that they only allow a few liters of water per hour to fall into the soil and the best way to water the plants at ground level where they need it the most. Installing an irrigation system such as sprinkler or drip system without automation has always been a difficult and frustrating probl...
