In Korea, irrigation technology using subsurface drip (SDI) is new in agriculture system. Many limitations of SDI are not well known. can damage crops from overwatering. To address this weakness, it important to improve and test the applicability with air injection (oxygation). Therefore we investigated soil oxygen (O2) carbon dioxide (CO2), root characteristics yield maize two conditions moist...

this experiment aimed to determine evapotranspiration, and responses of some yield and quality parameters of subsurface drip irrigated broccoli (brassica oleraceae l.). treatments included water application when available soil moistures were depleted 30, 40, and 50% during both spring and autumn cultivations. under a semi-arid climatic condition of tokat, turkey, the experiment was carried out ...

throughout the present study some vegetative and reproductive characteristics of rosa damascene fewer than three different irrigation regimes (100, 70 and 40% of potential evapotranspiration) through an application of surface vs subsurface drip irrigation systems were investigated. some morphological characteristics investigated, included the number of branches per plant, shading diameter, plan...

Canopy temperature is a useful indicator of crop water stress and can also be used for making timely irrigation scheduling decisions for center pivot and subsurface drip irrigation systems. However, it is not known how closely the measured canopy temperature from a circular area of the canopy surface compares with a larger continuous area that includes the full canopy width. A study was conduct...

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...

Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...

gations that leached the material from the emitter zone reduced its effectiveness. Quantitative descriptions of The transport of a pulse of trifluralin (2,6-dinitro-N,N-dipropyl-4the fate and transport of trifluarlin in the soil, therefore, [trifluoromethyl] benzenamime) applied via a subsurfacedripper was analyzed numerically. Results of the analyses suggest that the moveare essential for the ...

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...
