A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped groundwater. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m abov...

Technological innovations will leads to meet the present and future challenges of agriculture sector. Water is one important natural resource, since time immemorial, also acted as catalyst during Green Revolution helped India achieve self-sufficient status in food grain production. Fresh water only 2.6% total resources world has be utilized efficiently. Inspite coverage under irrigation phenome...

Abstract Traditional rice ( Oryza sativa L.) cropping systems under flooding irrigation combined with conventional tillage management are increasing threat due to a loss of soil quality and scarcity water resources, especially in Mediterranean environments. Hence, the development such strategies as no-tillage, application organic amendments, water-saving methods could be vital enhancing sustain...

In this study, the application of Bayes networks and fault tree analysis in reliability estimation have been investigated. Fault tree analysis is one of the most widely used methods for estimating reliability. In recent years, a method called "Bayes Network" has been used, which is a dynamic method, and information about the probable failure of the system components will be updated according to...

Investigation of different irrigation methods on plants is necessary due to limited water resources and the increasing need for food products. The purpose of this study was to evaluate the effect of sprinkler and drip irrigation systems and hormones on morphological and physiological characteristics of potato. Treatments included sprinkler and drip irrigation systems and hormones (gibbere...

according to the irrigation systems design standards, allowed pressure variation in lateral pipes is 20 percent. reasons for this rate selection, which since the 60's is performed, are not known. the increased changes in allowed pressure tubes to lateral pipes design, the increased sprinkling system required pressure and the increased nonuniform sprinkler distribution, so energy supply cos...
