“…Drought did not occur in this experiment, but previous research has found that in water-stress conditions, some sorghum varieties had higher WUE than maize (Farré & Faci, 2006). Therefore, further research on sorghum performance in varied climate conditions is necessary to better understand the range of ET and WUE in the rain-fed, Midwest.…”

“…Sweet sorghum was found to be less sensitive to drought than maize (Zegada-Lizarazu et al, 2012), and more water-useefficient than maize and other major grain crops (Steduto et al,1997;Katerji & Mastrorilli, 2014). However, previous studies on sorghum water dynamics have largely focused on grainyielding varieties (Steduto & Albrizio, 2005;Farré & Faci, 2006) and biomass sorghum in irrigated systems (Steduto et al, 1997;Farré & Faci, 2006;Rinaldi & Garofalo, 2013;Narayanan et al, 2013;Mullet et al, 2014;Hao et al, 2014Oikawa et al, 2014Yimam et al, 2015).…”

“…Some studies have shown greater biomass production for biomass sorghum than other C4 species, including maize and switchgrass (Hallam et al, 2001). Sweet sorghum, a variety with sugar-rich stems (Rooney et al, 2007), and grain sorghum, both with deep, extensive roots (Rooney et al, 2007;Zegada-Lizarazu et al, 2012), produced comparable biomass to maize when water was not a limiting factor, and more biomass than maize in water limited environments (Farré & Faci, 2006;Schittenhelm & Schroetter, 2014). Sweet sorghum was found to be less sensitive to drought than maize (Zegada-Lizarazu et al, 2012), and more water-useefficient than maize and other major grain crops (Steduto et al,1997;Katerji & Mastrorilli, 2014).…”

“…Irrigation deficit studies have shown that grain sorghum has higher WUE than maize with increasing severity of water stress (Farré & Faci, 2006). Therefore, it is reasonable to expect that biomass sorghum may be more water-useefficient than maize as the Midwest climate becomes increasingly variable (Farré & Faci, 2006).…”

“…There is evidence to suggest that sorghum and maize have differing biomass production and water dynamics; however, results vary based on environment, management, and species subtype (Steduto et al, 1997;Farré & Faci 2006;Zegada-Lizarazu et al, 2012;Oikawa et al, 2014).

Deficit irrigation is becoming an important strategy to reduce agricultural water use in arid and semi-arid regions. A field experiment was conducted in 2007 to examine the effect of deficit irrigation on the yield performance of maize crop under Arba Minch (Ethiopia) condition. Based on four phonological growth stages (establishment, vegetative, flowering and grain-filling stages) of maize, the crop was subjected to water deficit during one, two or three growth stages. The highest yield obtained was 5.933 tons/ha and the lowest was 3.467 tons/ha. Treatments that were water stressed during single growth stages such as first and second as well as consecutively during two stages, that is, first and second growth stages produced yields that are not significantly different from the yield achieved under fully irrigated treatment. Compared to the maximum yield, 29 to 42% lower yields were registered under treatments that were subjected to water deficit during three growth stages. Not only frequency of water deficit periods but also its timing was found to have effect on the final yield. Treatments which were stressed during two growth stages had 2.2 (0011) to 38.5% (1010) yield reduction compared to the maximum yield. The highest yield reduction was observed under the treatment which was irrigated only during the fourth growth stage (0001), followed by treatment irrigated during first and third growth stages (1010) and then treatments irrigated only during second stage (0100) . This shows that prolonged deficit over three growing stages will have more yield reduction impacts. Plots stressed during third and fourth growth stages were found to produce lower yields indicating the severe effects of water stress during flowering (tasseling and silking) and early grain-filling stages on yield. The comparison of water savings achieved under different treatments that had no significant differences in yield level from full irrigated plot (1111I) ranged from 18.2% (treatments 0111 and 1011) to 36.4% (0011). This indicates that water deficit during first and second growth stages had no significant effect on the grain yield of corn and it is worthwhile to save irrigation water under this condition. The water use efficiency increased with decreasing water supply and increasing yield level. Irrigation water use efficiency increased with decreasing water supply and related yield which may not be desirable from farmers' perspective.

Water is a crucial factor affecting expression of crop yield potential. A field experiment was conducted during 2014 and 2015 to determine the effect of limited water on growth, yield, water productivity (WP), nutritive value, and physiological parameters of silage corn (Zea mays L.) grown in a semi-arid region. Hybrid 'P8107HR' was planted in replicated plots under 100ETc (100% crop evapotranspiration), 80ETc, 60ETc, and limited 100ETc (100ETc from planting to V9, no water from V9 to R3, then 100ETc again) managed with a surface drip irrigation. Canopy height, leaf area index (LAI), specific leaf area (SLA), biomass yield, WP, and nutritive value were determined. Photosynthesis (A), stomatal conductance (gs), transpiration (E), and intrinsic WP (iWP) were obtained with an infrared gas analyzer from V14 to R2 stages. Relative water content (RWC) of leaves was determined at V8, V12, VT, and R3 stages. Results showed that canopy height and biomass yield were greatly affected by water stress. Biomass yield decreased by 40% in the limited 100ETc treatment compared to 100ETc, with no effect of irrigation on nutritive value. Water-stressed plants from V14 to R2 were affected in their ability to perform gas exchange and exhibited changes in crop growth and biomass yield. RWC was affected by water stress, mostly under 60ETc at V8 (71%) and VT (78%). Overall, limited water at late vegetative and early reproductive stages affected physiology and yield of silage corn, indicating that irrigation timing is a key factor for optimizing silage corn production in water-scarce regions.
