Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...

Close management of irrigation could have considerable impacts on water resources, especially for cropping systems dominated by corn. The experiment was carried out to compare the influence porous capsule (PCI), surface drip (DI), and subsurface (SDI) systems, with or without mulching, actual evapotranspiration (ETc act), crop coefficients (Kc single Kc dual), biomass yield, use efficiency (WUE...

This study compared the performances of subsurface drip irrigation (SDI) to sprinkler (SI) cool-season turf mix (CS) and warm-season (WS) turfgrass species while investigating their response different scheduling strategies. Moreover, suitability crop water stress index (CWSI) for monitoring was tested. Irrigation applied up field capacity when 30%, 50% 70% total available consumed. All paramete...

Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...

Soil surface resistance increase quickly during the first three days after irrigation or rain event. By explicitly incorporating surface resistance in simple equations, daily total evaporation estimation of a drip-irrigated olive grove was significantly improved. This increase in soil surface resistance could explain why observed cumulative soil evaporation is higher in locations with lower irr...

A laboratory soil column experiment was first conducted to analyze water movement in latosol of sugarcane field under drip irrigation from single-point source at different emitter discharge rates. Next, a mathematical model of soil water movement under drip irrigation from single-point source was built using Hydrus-3D, which could accurately simulate the shape of the wetted soil volume and the ...

Sandy fields have been reclaimed to exploit the grain production potential in northwestChina. A 2-year statistically replicated field study was conducted to determine the effects ofmulched drip irrigation on soil water, soil nitrate, shoot root growth and yields of maize on asandy field in the Hetao irrigation district. Treatments included border irrigation (BI), fullymulched drip irrigation (F...

-Water plays an important role in everyday’s life. Agriculture is a backbone of our country and it uses 85% of available fresh water for irrigation. Irrigation is the method of supplying the water to the plants artificially. In India, Farmers follow different irrigation systems to cultivate the crops. The different types of irrigation methods include sprinkler irrigation, drip irrigation, surfa...

This corn intensification study was conducted under subsurface drip irrigation (SDI) from 2017 to 2021 at the Kansas State University Northwest Research-Extension Center near Colby, KS. Two hybrids (Pioneer 1151 and Pioneer 11197) were grown with advanced fertilization three plant densities (42,000, 38,000, 34,000 plants/a) using levels (115, 100, or 85% of calculated well-watered ET minus rain...

Enhanced water use efficiency (WUE) is the key to sustainable agriculture in arid regions. The installation of capillary barriers (CB) has been suggested as one potential solutions. CB effects are observed between two soil layers with distinctly different hydraulic properties. A helps retain upper, relatively fine-textured layer, suppressing losses by deep drainage. However, retaining a shallow...
