Global agricultural production is heavily sustained by irrigation, but irrigation system efficiencies are often surprisingly low. However, our knowledge of irrigation efficiencies is mostly confined to rough indicative estimates for countries or regions that do not account for spatiotemporal heterogeneity due to climate and other biophysical dependencies. To allow for refined estimates of globa...

A 4-year study was conducted to establish the effects of drip irrigation configuration and rate on fruit yield and quality of young highbush blueberry plants (Vaccinium corymbosum L. ‘Duke’). Plants were grown in a silt loam soil on raised beds and were non-irrigated or irrigated using either one or two lines of suspended drip tape. Each line configuration had in-line emitters spaced every 0.3 ...

in this research, effects of subsurface drip irrigation method on soil and tomato yield was investigated under different salinities and two irrigation management strategies: m1= alternating irrigation with fresh water and saline water, and m2= saline water in the first half of each irrigation event and fresh water in the second half. the experiment was conducted in 320 m2 area including 30 plot...

where is the membrane time constant, is the membrane space constant, and V is the membrane potential. This equation describes the propagation of electricity along a core conductor, as some of the current escapes through a nonperfect insulator to an infinite external conductor. This cable equation was successfully adapted from the underwater telegraph to axons (4) and later to dendrites (9–12) a...

High air temperatures during the crop growing season can reduce harvestable yields in major agronomic crops worldwide. Repeated and prolonged high night air temperature stress may compromise plant growth and yield. Crop varieties with improved heat tolerance traits as well as crop management strategies at the farm scale are thus needed for climate change mitigation. Crop yield is especially sen...

the current study was carried out with the aim of evaluating the effects of pressurized and furrow irrigation methods on the distribution of salinity and moisture in the soil profile. the experimental study design was a split plot layout with three irrigation method including furrow, surface drip (sd) and subsurface drip irrigation (ssd) using two water qualities, municipal effluent (0.509 ds/m...

Restricted water resources are a limiting factor for irrigation applications throughout the world. The effects of irrigation regimes (amount) on cotton lint yield are known, but there is little information on the effect of irrigation regimes on seed quality of cotton. In this study, the effects of deficit irrigation after the onset of flowering on lint yield and seed quality of cotton (Gossypiu...

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, ...

[1] In this study, two parameterizations for different irrigation techniques have been implemented in a regional climate model. These implementations allow for a comparative study of water use and land–atmosphere interactions associated with traditional flood irrigation—a widespread but highly water-inefficient practice—and water-conserving drip irrigation. Both parameterizations yield realisti...

Plastic mulching with drip irrigation is a new water-saving rice cultivation technology, but little is known on its productivity and water-saving capacity. This study aimed to assess the production potential, performance, and water use efficiency (WUE) of rice under plastic mulching with drip irrigation. Field experiments were conducted over 2 years with two rice cultivars under different culti...
