“…For example, Howell, Evett, Tolk, and Schneider (2004) reported lint yields that were 33 and 65% smaller under half‐FI and NI, respectively, compared with FI. Additionally, DeLaune, Mubvumba, Ale, and Kimura (2020) reported 7 and 12% reductions in lint yields in treatments that received 33 and 67% less irrigation water than the largest treatment in the Texas Rolling Plains. Pettigrew (2004) reported a 35% yield difference between FI and NI in Stoneville, MS. Several studies have reported that soil moisture deficits reduce the boll weight and ultimately the overall yield due to the induced water stress (Onder, Akiscan, Onder, & Mert, 2009; Pettigrew, 2004).…”

Water scarcity threatens the sustainability of irrigated cotton production in many regions around the world. Consequently, there is a critical need to identify and test strategies that optimize water use for cotton production. This 4-yr study evaluated the effects of three irrigation treatments (full irrigation [FI], reduced irrigation [RI] at 75% of FI, and no irrigation [NI]) on cotton yield, fiber quality, and irrigation water use efficiency (IWUE) at a field that relies on groundwater for irrigation in west-central Oklahoma. Compared with FI, lint and seed yields did not change significantly under RI. The reductions in lint and seed yields were significant at 64 and 65% under NI, respectively, compared with FI. No significant differences in fiber quality were observed among the irrigation treatments. In addition, reducing irrigation application improved the IWUE of lint and seed by 9 and 8%, respectively. Based on these findings, reducing groundwater extraction by 25% appears to be an effective strategy to achieve water conservation while limiting negative impacts on yield quantity and quality for cotton production in west-central Oklahoma.

A method for calibrating models of agricultural production and resource use presented by Howitt [1] for policy analysis is proposed to leverage multidisciplinary agricultural research at the National Center for Alluvial Aquifer Research (NCAAR). An illustrative example for Sunflower County, MS is presented to show how plot-level research can be extended to draw systemic region or basin wide implications. A hypothetical improvement in yields for dryland soybean varieties is incorporated to the model and shown to have a positive impact on aquifer outcomes and producer profits. The example illustrates that a change in one practice-crop combination can have system-wide impacts as evidenced by the change in acreages for all crops and practices.

“…Adoption of no tillage with or without cover crop for cotton production resulted in significantly greater net returns (NR) than conventional tillage and numerically greater NR than reduced tillage on a clay loam soil (DeLaune et al, 2012). In a later study concerning the same research plots for the period 2013 through 2018, SDI cotton yields with no tillage and a terminated cover crop were 10% greater than with conventional tillage (DeLaune et al, 2020).…”

HighlightsSubsurface drip irrigation (SDI) has continued to expand in irrigation area within the U.S. during the last 15 years.Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, and turf).SDI usage on many crops has matured through research and development of appropriate strategies and technologiesDespite some persistent challenges to successful use of SDI, important opportunities exist for further adoption.Abstract. Subsurface drip irrigation (SDI) offers several advantages over alternative irrigation systems when it is designed and installed correctly and when best management practices are adopted. These advantages include the ability to apply water and nutrients directly and efficiently within the crop root zone. Disadvantages of SDI in commercial agriculture relative to alternative irrigation systems include greater capital cost per unit land area (except for small land parcels), unfamiliar management and maintenance protocols that can exacerbate the potential for emitter clogging, the visibility of system attributes (components and design characteristics) and performance, and the susceptibility to damage (i.e., rodents and tillage) of the subsurface driplines. Despite these disadvantages, SDI continues to be adopted in commercial agriculture in the U.S., and research efforts to evaluate and develop SDI systems continue as well. This article summarizes recent progress in research (2010 to 2020) and the status of commercial adoption of SDI, along with a discussion of current challenges and future opportunities. Keywords: Drip Irrigation, Irrigation, Irrigation systems, Microirrigation, SDI, Water management.
