Modeling of irrigation methods is one the most important techniques that contribute to future modern agriculture. This will conserve water as scarcity a major threat for In this study, AquaCrop model was used different maize in field trails Al-Yousifya, 15 km Southwest Baghdad. Field experiments were conducted two seasons during 2016 and 2017 using five including furrow, surface drip subsurface...

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...

There is a need to optimize water-nitrogen (N) applications to increase seed cotton yield and water use efficiency (WUE) under a mulch drip irrigation system. This study evaluated the effects of four water regimes [moderate drip irrigation from the third-leaf to the boll-opening stage (W1), deficit drip irrigation from the third-leaf to the flowering stage and sufficient drip irrigation thereaf...

abstract assessing moisture in the soil under cultivation of crops to achieve high performance and reduced water are necessary. knowledge of the moisture distribution in the root zone, time consuming and costly field tests that simulation models, a suitable alternative in answer to issues of movement and are water distribution. in this study assessment of soil moisture, to aid swap simulation m...

Air concentrations of methyl isothiocyanate (MITC) were determined near two fields treated with metam-sodium (MS) by subsurface drip irrigation. The two study fields showed measurable airborne MITC residues during application of MS and for periods up to 48 h postapplication. Using a Gaussian plume dispersion model, flux values were estimated for all of the sampling periods. On the basis of the ...

Although rainfall in the United States Mid-South is sufficient to produce corn (Zea mays L.) without irrigation in most years, timely irrigation has been shown to increase yields. The recent interest in ethanol fuels is expected to lead to increases in US corn production, and subsurface drip irrigation (SDI) is one possible way to increase application efficiency and thereby reduce water use. Th...

Long-term use of drip irrigation technology may lead to root degradation and affect shoot growth and yield. A field experiment was conducted to investigate aboveand belowground growth responses to drip irrigation under mulch film (DI) in comparison to flood irrigation under mulch film (FI) in cotton. The monolith method was used to harvest roots at seven timepoints in the growth periods, and th...

Detailed information on the root system under drip irrigation will help in more efficient scheduling. Although input of previous crop residues is effective increasing soil fertility, little known about its effect system. This study aimed to investigate effects methods (drip or flood) and different management morphological characteristics distribution physiological functions rice cultivar ‘Hinoh...

introduction: the to be limited available water amount from one side and to be increased needs of world population from the other side have caused increase of cultivation for products. for this reason, employing new irrigation ways and using new water resources like using the uncommon water (salty water, water drainage) are two main strategies for regulating water shortage conditions. on the ot...
