Yosef and Sagiv, 1982; Stark et al., 1983; Burt et al., 1995). However, very few studies have shown a benefit Subsurface-drip irrigation and fertigation with fluid N fertilizer of frequent or continuous fertigation compared with sources offers substantial flexibility for N fertilizer management. Fertiless frequent fertigation. Bar-Yosef and Sagiv (1982) gation events can be scheduled as often a...

Measuring evapotranspiration (ET) components in cotton fields under mulched drip irrigation is needed to improve water use efficiency and promote the development of water-saving agriculture. In this study, an Eddy Covariance (EC) system was used observe water-carbon fluxes arid region during two years (2021–2022). The Underlying Water Use Efficiency (uWUE) method partition ET into transpiration...

The impact of different combinations water–nitrogen coupling on maize yield and the environment needs investigation. Low, medium, high levels irrigation N application gradients were studied through field experiments to elucidate suitable zone for spring in West Liaohe Plain during three hydrological year patterns under drip with plastic film. effects couplings yield, water- nitrogen-use efficie...

ِdfferent drip (surface and subsurface) and furrow irrigation methods effects on grain, oil and water use efficiency based on grain black cumin(nigella sativa l.) as medicinal plants was investigated. for this purpose, experiment over the past two years (2009 and 2010) in a randomized complete block was designed in three replications. treatments in this research were consisting of 50, 75 and 100...

with population growing throughout the world, it is necessary to optimize water use,especially in agricultural lands. in order to conduct technical and economical evaluation ofdrip and furrow irrigation methods under deficit irrigation of cotton, a field experiment wascarried out during 2010 growing season at experimental farm of orzoueyeh agricultural andnatural resources research center in ke...

this study evaluates the effect of irrigation method on the water use efficiency and yield of onions at the zahak agricultural research station in sistan province. the testing was conducted using a split plot arrangement and a randomized complete block design with three replications during the 2005-2006 crop seasons. irrigation methods were basin and drip tape irrigation and the irrigation leve...
