“…Meanwhile, too much N fertilizer application does not increase crop production (Camp et al 1997;Thompson et al 2002a, b;Sorensen et al 2004;Mahajan and Singh 2006;Cabello et al 2009). SDI has higher soil fertility after potato harvesting compared with DI, although this effect is not significant (Selim et al 2009). …”

A two-year field experiment was conducted in 2007 and 2008 to investigate different bell pepper responses to subsurface drip irrigation (SDI) and surface drip irrigation (DI) under four nitrogen levels: 0, 75, 150, and 300 kg/ha N (N 0 , N 75 , N 150 , and N 300 , respectively). Irrigation interval was set at 4 days. Bell pepper yield under SDI was significantly higher than that under DI by 4% in 2007 (13% in 2008). Water consumption under SDI was lower than that under DI by 6.7% in 2007 (7.3% in 2008). Meanwhile, root length density under SDI was obviously higher than that under DI by 11.8% in 2007 (12.5% in 2008). The percentage of root length below 10-cm soil depth under SDI was higher than that under DI by 7%, proving that SDI promotes crop root growth and enhances downward root development. Soil N residue under SDI was lesser than that under DI. Lastly, SDI with N application of 150 kg/ha is recommended as an optimal fertigation practice in improving bell pepper yield and water-use efficiency, as well as in NO 3 --N leaching.

“…According to Patel and Rajput (2007) a subsurface drip system could be used to apply water in small amounts and achieve water saving in comparison to surface drip irrigation in sandy loam textured soil. The use of subsurface drip offers many other advantages for crop production, including less nutrients leaching compared to surface irrigation, higher yields, a dry soil surface for improved weed control and crop health and the ability to apply water and nutrients to the most active part of the root zone (Enciso et al 2005;Lamm and Camp 2007;Selim et al 2009). Lamm and Trooien (2003), for instance, found that corn yield was the highest under subsurface drip at irrigation level of 75% crop water requirements.…”

Efficient water delivery systems such as drip irrigation can contribute towards increasing crop yield potential, improving crop water and fertilizer use efficiency. However, critical management considerations such as subsurface drip irrigation are necessary to attain improved irrigation efficiencies and production benefits particularly under arid regions. The objective of this study was to determine the effect of two irrigation methods, surface and subsurface drip irrigation combined with four irrigation levels, 100, 80, 60 and 40% of crop evapotranspiration on yield and yield components of potato grown on sandy soil. The field experiments were conducted in the years 2008 and 2009. In terms of soil water availability to plants, subsurface drip provided more favorable growth conditions for plant growth and maintained higher soil water content at the root zone, which resulted in a significant higher potato yield compared to surface drip irrigation. The difference between the two irrigation methods on yield components was concentrated on the mean tuber weight per plant, while no significant difference was found on the tuber number per plant. Reducing the amounts of applied water significantly decreased total potato yield and its components. Under subsurface drip irrigation, reducing amounts of applied water to 80% ETc gave comparable yield and yield components to surface drip at full irrigation supply, indicating that 20% irrigation water can be saved without affecting the potato yield. At all irrigation levels, subsurface drip recorded higher water use efficiency (WUE) over surface drip. Maximum value was observed at 40% ETc. Fertilizer use efficiency (FUE) was also higher under subsurface drip and reduced significantly under both irrigation methods with increasing water deficit. These results suggested that subsurface drip offers the potential of better water management with respect to saving and distribution of water in the root zone and to obtain maximum yield accompanied by highest water and FUE.Keywords Subsurface drip irrigation · Dry stress · Potato · Water use efficiency · Fertilizer use efficiency Die Effizienz der Unterflur-Tropfbewässerung im Kartoffelanbau unter verschiedenen TrockenstressbedingungenZusammenfassung Effiziente Bewässerungssysteme, wie Tröpfchenbewässerung können zur Steigerung des Ertragspotenzials, sowie zur Verbesserung der Wasser-und Dün-gernutzungseffizienz beitragen. Allerdings sind kritische Erwägungen des Unterflur-Tröpfchenbewässerungs-Managements notwendig, um eine verbesserte Effizienz der Bewässerung und Produktionsvorteile, vor allem in ariden Regionen, zu erreichen. Ziel dieser Studie war es, die Wirkung von zwei Bewässerungsmethoden, eine oberflächliche und eine unterirdische Tropfbewässerung, kombiniert mit vier Bewässerungsstufen 100, 80, 60 und 40 % der Evapotranspiration, auf Ertrag und Ertragskomponenten der Kartoffel auf sandigen Böden zu untersuchen.

“…Although numerous studies have been reported on the ability of HS extracted from different organic materials to stimulate nutrient (N, P, K, Fe, Zn, etc.) uptake, this effect on vegetables has mainly been reported for soil-applied HS (Demir et al, 1999;Atiyeh et al, 2002;Selim et al, 2009) trient status of different crops are scarce and is usually restricted to N and P (Zaghloul et al, 2009). At application rates (1.5 L×ha -1 HS) used in the present experiment, HS preparations could not been considered as the direct nutrient source, and a beneficial effect of HS as a nutrient carrier or stimulator of nutrient uptake under limited nutrient conditions in soil was not indicated.…”
