The cylindrical filters presently used in drip irrigation systems frequently clog, increasing pressure loss and lowering the flow rate through the filters. This work investigates alternative filtration strategies that increase the reliability of, and are compatible with, existing systems. To test different filtration strategies, a drip irrigation test setup was built to measure the pressure los...

In semi‐arid areas such as western Nebraska, interest in subsurface drip irrigation (SDI) for corn is increasing due to restricted irrigation allocations. However, crop response quantification to nitrogen (N) applications with SDI and the environmental benefits of multiple in‐season (IS) SDI N applications instead of a single early‐season (ES) surface application are lacking. The study was cond...

optimal use of water resources is essential to decrease cost and maximize available water resources. subsurface drip irrigation can increase irrigation and water use efficiency. this irrigation method distributes water into the soil, leaving the surface of the soil dry and decreasing evaporation. in the design of subsurface drip irrigation (sdi) systems, the dimensions of the wetted onion deter...

Water scarcity is a major constraint facing vegetable production sustainability in open field farming of arid regions like the Kingdom Saudi Arabia. This study was carried out an Research and Training Station King Faisal University eastern region Kingdom. The objective to assess influences polymer addition (PA), deficit irrigation regime (DIR), their combination on water use efficiency (WUE) mu...

abstract this study was conducted to determine the impacts of plastic mulch, drip irrigation method and different amount of water and their interactions on yield, water use efficiency (wue) and quality characteristic of tomato (mobile cultivar). the study was conducted in torogh agricultural research station, razavi khorasan province. the study was done during 2007-2008. experimental design was...

Water management and utilization is an ongoing problem in developing countries with semi-arid to arid climates such as Afghanistan. The lack of effective irrigation systems are oftentimes the most limiting factor for maximizing agricultural productivity in these countries. In Afghanistan, the most widely used irrigation methods are basin/border for cereal crops and furrow for vegetables and gra...

Applications of modern micro-irrigation methods are inevitable for optimum water use due to the limitations imposed by irrigation resource scarcity. Regardless shortages and associated challenges in dry areas, date palm trees consumes an excessive quantity annually using conventional methods. Therefore, present study was designed evaluate effects surface subsurface systems, i.e., drip (SSDI), c...
