Highlights Subsurface drip irrigation (SDI) has continued to expand in area within the U.S. during last 15 years. Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, turf). usage on many crops matured through research development of appropriate strategies technologies Despite some persistent challenges successful use SDI, important opportunities...
اثرات پستی و بلندی و آبیاری بر تکامل خاکها و تنوع کانیهای رسی در برخی از خاکهای گچی استان خوزستان
This study was done to evaluate the effect of topography, water table, and irrigation on gypsc soil development and clay mineral diversity in Ram-Hormuz Plain, Khuzestan Province. To localize, 10 profiles in this region that covered all purpose irrigation and topography situation were described. The results showed that the soils could be classified in Entisols, Inceptisols and Aridisols orders....
this study was conducted to determine the possibility of a crop water stress index (cwsi) to schedule irrigation for pistachio tree under subsurface drip irrigation. the effects of two irrigation intervals consisting 3 (i3) and 14 (i14) days based on measuring soil water content were investigated on the cwsi. from 22 may (doy 143) to 22 september (doy 266), the evapotranspiration in i3 and i14 ...
Innovative irrigation solutions have to face water scarcity problems affecting the Mediterranean countries. Generally, surface (DI) or subsurface drip irrigation systems (SDI) have the ability to increase water productivity (WP). But the question about their possible utilization for crops such as corn would merit to be analysed using an appropriate economic tool. The latter would be necessary b...
Semi-arid region can benefit greatly from surface and subsurface drip irrigation techniques in overcoming the problem of water scarcity. Therefore, a field study was carried out at research farm CCS Haryana Agricultural University, Hisar, during winter (rabi) season 2019–20 2020–21 to investigate effectiveness on growth yield broccoli (Brassica oleracia L.). Subsurface shows higher moisture con...
