“…WUE, EY, and EWR were higher for both species in 2015, likely due to greater SWtot, GDD, and precipitation in 2015, relative to 2014. Interannual variability in WUE was explained by different biomass accumulation between growing seasons, rather than changes in total ET, which is consistent with findings in the literature (Steduto et al, 1997;Narayanan et al, 2013;Hao et al, 2014;Dietzel et al, 2015). While both species had similar total ET, the pattern of ET accumulation within the season (Fig.…”

“…Our biomass sorghum WUE observations (3.1-3.8 g kg -1 ) were similar to the average WUE for rain-fed biomass sorghum available in the literature (3.8 g kg -1 ; Hao et al, 2014;Yimam et al, 2015). For irrigated systems, our biomass sorghum WUE results are comparable to literature values (3.9 g kg -1 ; Garofalo & Rinaldi, 2013;Hao et al, 2014;Oikawa et al, 2014).…”

“…However, we found greater total ET than Hao et al (2014) who used a soil water content approach for irrigated biomass sorghum in Texas (227-517 mm). Oikawa et al (2014) found higher total ET (1094 mm) for biomass sorghum grown in the Imperial Valley of California; however, their annual total (Feb-Nov) was reported as the sum of ET measured over three growing periods (ratooning) in a hot, dry environment.…”

“…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).…”

Simulating impacts of nitrogen fertilization using DAYCENT to optimize economic returns and environmental services from bioenergy sorghum production

et al. 2020

Inappropriate nitrogen (N) fertilization rate could cause yield and economic losses and negative environmental impacts. This study was conducted to explore optimum N rate for a promising biofuel crop-bioenergy sorghum [Sorghum bicolor (L.) Moench]. The biogeochemical model, DAYCENT, was verified with an eight-year field trial and then used to simulate the long-term (35 years) effects of N fertilization on aboveground biomass carbon (C), soil organic C (SOC), carbon dioxide (CO 2), and nitrous oxide (N 2 O) emissions. Associated with the simulated metrics, N use efficiency (NUE), net greenhouse gas (GHG) emissions, and net economic return to N (RTN) were calculated to determine the optimum N rate. The model was capable of reproducing the field measurements with r 2 of 0.57, 0.47, 0.55, and 0.34 for aboveground biomass C, SOC, CO 2 , and N 2 O, respectively. Projection with 0-350 kg N ha −1 fertilization in increments of 70 kg N ha −1 indicated positive responses of aboveground biomass C and SOC to increasing N but with little increase above 140 kg N ha −1. Declining NUE and increasing net GHG emission at field scale were predicted as N rate increased. When considering GHG mitigation from fossil fuel replacement, net GHG emission decreased first and leveled off at a N rate of 70-140 kg N ha −1 before increasing. Net economic RTN increased first and peaked when N rate

Annual forage impacts on dryland wheat farming in the Great Plains

Wheat (Triticum spp.) dominates dryland grain crop production in the North American Great Plains and other regions with semi‐arid steppe climates. A common practice is to alternate winter or spring wheat with a 14‐ to 21‐mo fallow period to allow for soil‐water recharge, despite economic inefficiencies and environmental degradation. Replacing fallow with non‐cereal grain and seed crops often reduces future wheat yields due to increased water stress during grain fill. The use of annual forages may not have the disadvantages associated with grain and seed crops. The objective of this review was to determine benefits and challenges of incorporating annual forages into dryland wheat systems in semi‐arid steppe climates, using the Great Plains within the United States as a model system. Results indicate that: (a) cool‐ and warm‐season, annual grass and broadleaf species can be grown for forage across the region; (b) forage production will be less risky than grain and seed crop production under predicted climate‐change scenarios; (c) grazing annual forages may offer advantages (e.g., nutrient cycling, improved soil structure, added revenue from livestock) over mechanically harvesting annual forages; (d) the lack of infrastructure and local markets impede the use of annual forages to diversify wheat‐based cropping systems in the region; and (e) limited networking among researchers hinders the advancement in knowledge on how annual forages can be used to improve dryland wheat system resilience.
