abstract this study was conducted to determine the impacts of different drip irrigation method and amount of water on yield and water use efficiency of tomato in varamin agricultural research center, iran. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with three replications. three different drip irrigation method; surface dr...

abstract- a detailed understanding of crop rooting systems will facilitate water use reduction, optimized nutrient uptake and irrigation scheduling more efficiently. a field experiment was conducted during 2005-2006 to investigate sugar beet rooting depth growth, irrigated with three irrigation methods (subsurface drip, surface drip and furrow) and two water qualities (recycled wastewater: ec= ...

During 2015, vines receiving season-long drip irrigation delivered into the lower root zone via hard plastic tubes yielded 70 % of commercial production while receiving only 15% of the water as the vines receiving full commercial rates of surface drip irrigation. Vines receiving direct root-zone (DRZ) irrigation at rates reduced to 60, 30, and 15% of commercial drip irrigation (DI) produced ind...

Delineating the depth and extent of the watermelon [Citrullus lanatus (Thumb.) Matsum. & Nak.] root zone assists with proper irrigation management and minimizes nutrient leaching. The objective of this 3-year field study was to measure root distribution and root length density of watermelon (cv. Wrigley) grafted on two different rootstocks (Lagenaria siceraria cv. ‘FR Strong’ and Cucurbita mosc...

ِ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...

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...

Roots are the key elements in water saving rice cultivation. So, Background the response of rice roots are to be phenotyped under varied drip irrigation treatments. : This study describes an investigation on rice root Methods phenotyping under drip irrigation treatments in split-split plot design. Two lateral spacing levels (0.8 and 1.2m), laid at two depths of sub surface irrigation (5-10 and ...

coriander is one of the important economic plants for medicinal production. this investigation consists of the effects of different drip irrigation (surface and subsurface) and furrow irrigation methods on grain, oil and essential of coriander. for this purpose, experiment over the past two years (2010 and 2011) in a randomized complete block was designed in three replications. treatments were ...
