“…The lowest values of Ky for date palm fruits were 0.16 and 0.12 for the 1 st and 2 nd seasons, respectively, under the DIS, IR=85% and MS treatment.The maximum values were 1.95 and 1.89 for the 1 st and 2 nd seasons, respectively, under theBIS, IR=70% and UMS treatment. These results may be attributed to date palm trees'high tolerance for water and temperature stress.These results are consistent with the findings of Kirda et al (1999a) and Steduto et al (2012).

“…The yield response factor is an indicator of whether the crop is tolerant to water stress. The yield response factor is larger than unity and the expected yield ratio decreased with increasing deficit evapotranspiration (Kirda et al, 1999a). The yield response factor (Ky) is the coefficient used to indicate crop sensitivity to a water deficit at any growth stage, and it is commonly used in irrigation management (Steduto et al, 2012).…”

private farm in the El-Baharia Oasis area, Giza Governorate, Egypt, to study the effect of different irrigation systems (deep drip (DIS), micro jet (MIS), bubbler (BIS)) and applied irrigation water levels (IR: 100,85,70%) under mulched soil (MS) and un-mulched soil (UMS) and to determine the marketable yield (MY), crop quality parameters, actual evapotranspiration (ETa), water-use efficiency (WUE), irrigation water-use efficiency (IWUE), yield response factor (Ky) and actual crop coefficient (Kca) for date palm trees (Phoenix dactylifera L.). The experimental design was a split-split plot design with three replicates. The results showed that the MY and studied quality parameters (except the total soluble solid (TSS) content) of the date palm fruits were highest under the DIS, IR=100% and MS treatment for both seasons. For the 1 st and 2 nd seasons, the lowest seasonal ETa values were 564.41 and 526.78 mm, respectively under the DIS, IR=70% and MS treatment;the maximum date palm fruit WUE and IWUE were 3.22 and 1.55 kg m-3 and 3.61 and 1.62 kg m-3 , respectively under the DIS, IR=70% and MS treatment; the minimum Ky for date palm fruits was 0.16 and 0.12, respectively under the DIS, IR85% and MS treatment; and the minimum seasonal Kca values for the initial (I), development (D), mid-season (M), and late-season (L) growth stages were 0.29, 0.17, 0.28, 0.18 and 0.23 and 0.29, 0.15, 0.25, 0.14 and 0.21, respectively under the DIS, IR=70% and MS treatment. This study concluded that the cultivation of date palm trees under the DIS, IR=70% and MS treatment could save approximately 38% of the IR and increase the MY of date palm fruit by approximately 20 and 22% for the 1 st and 2 nd seasons, respectively, compared with the control treatment (BIS, IR=100% and UMS).

“…In these systems, the crop is exposed to a certain level of water stress either during a particular period or throughout the whole growing season (Bekele and Tilahun, 2007). The final yield of the crops may be negatively affected by this strategy, the severity of which depends on the timing of induced water stress (Kirda and Kanber, 1999).…”

Grain Sorghum Response to Arbuscular Mycorrhiza and Phosphorus Fertilizer under Deficit Irrigation

et al. 2014

Deficit irrigation systems have been considered as practical strategies to overcome shortage of irrigation water in arid and semiarid regions. To assess the response of grain sorghum [Sorghum bicolor (L.) Moench] to deficit irrigation and whether arbuscular mycorrhizal fungi (AMF) can moderate drought stress influence on grain yield, a 2-yr field experiment was conducted using split-split lay out on a randomized complete block (RCB) design. Irrigation (full and deficit) was assigned to the main plots. Subplots were allocated to two genotypes (Kimiya and Speedeh) and P sources viz: no fertilizer, sole chemical P fertilizer, seed inoculation with AMF and combined fertilizer (50% of the chemical P fertilizer + AMF) were assigned to the sub-subplots. Results indicated that deficit irrigation reduced grain yield of Kimia and Speedeh by 16 and 26%, respectively, while improving their irrigation water use efficiency (IWUE). Grain yield adjustment by sorghum to water stress was mainly through reducing the number of grains per panicle rather than grain mass. Application of all forms of P fertilizer improved grain yield of sorghum; however, under drought stress, plants were more responsive to combined fertilizer and used irrigation water more efficiently. The root colonization percentage was greater in Kimiya than Speedeh under full and deficit irrigation, however, both genotypes showed a lower degree of root colonization under drought conditions. Application of combined fertilizer could be considered as an alternative to chemical P fertilizer when irrigation water is limited.

“…WUE is the main factor that limits plant productivity; crop yield losses are inevitable when the plant is exposed to water stress (English, 1990). The correct application of the DI needs detailed assessment of economic yield losses caused by water stress (Kirda et al, 1999;Geerts and Raes, 2009). It is important to apply optimum irrigation and fertilization programs for stabilization and maximization yield and quality.…”

-1 as urea. The field experiment was setup employing a randomized split-plot design with three replications. N levels were assigned to the main plot and irrigation to the sub plot. Irrigation water amount applied, fruit yield and some quality parameters, yield response factor, irrigation water use efficiency, water use efficiency, water saving at different N levels and irrigation regimes were determined. Results show that irrigation regimes and N levels had significant effects on fruit yield. The best combination of treatments was N3*DI-low (T19) with a yield of 59.77 t ha -1 which corresponds to 10% yield loss providing 55% water saving. It could be applied for sustainable production, saving a significant amount of water and increasing the nitrogen use efficiency, where water is scarce.
