Most irrigation water comes from groundwater. Persistent drought and increased competition for water resources threaten long-term viability of groundwater resources, which motivated our research to develop strategies to increase water productivity without noticeable reduction in maize yield. Results from previous research at the University of Nebraska-Lincoln (UNL) experiment stations in 2005 and 2006 found that it was possible to substantially reduce irrigation amounts and increase irrigation water use efficiency (IWUE) and crop water use efficiency (CWUE) (or crop water productivity) with little or no reduction in yield using an irrigation regime that applies less water during growth stages that are less sensitive to water stress. Our hypothesis was that a soil moisture-based irrigation management approach in research fields would give similar results in large production-scale, center-pivot irrigated fields in Nebraska. To test this hypothesis, IWUE, CWUE, and grain yields were compared in extensive on-farm research located at eight locations over two years (16 site-years), representing more than 600 ha of irrigated maize area. In each site-year, two contiguous center-pivot irrigated maize fields with similar topography, soil properties, and crop management practices received different irrigation regimes: one was managed by UNL researchers, and the other was managed by the farmer at each site. Irrigation management in farmer-managed fields relied on the farmers\u2019 traditional visual observations and personal expertise, whereas irrigation timing in the UNL-managed fields was based on pre-determined soil water depletion thresholds measured using soil moisture sensors, as well as crop phenology predicted by a crop simulation model using a combination of real-time (in-season) and historical weather data. The soil moisture-based irrigation regime resulted in greater soil water depletion, which decreased irrigation requirements and enabled more timely irrigation management in the UNL-managed fields in both years (34% and 32% less irrigation application compared with farmer-managed fields in 2007 and 2008, respectively). The average actual crop evapotranspiration (ETC) for the UNL- and farmer-managed fields for all sites in 2007 was 487 and 504 mm, respectively. In 2008, the average UNL and average farmer-managed field had seasonal ETC of 511 and 548 mm, respectively. Thus, when the average of all sites is considered, the UNL-managed fields had 3% and 7% less ETC than the farmer-managed fields in 2007 and 2008, respectively, although the percentage was much higher for some of the farmer-managed fields. In both years, differences in grain yield between the UNL and farmer-managed fields were not statistically significant (p = 0.75). On-farm implementation of irrigation management strategies resulted in a 38% and 30% increase in IWUE in the UNL-managed fields in 2007 and 2008, respectively. On average, the CWUE value for the UNL-managed fields was 4% higher than those in the farmer-managed fields in both years. Reduction in irrigation water withdrawal in UNL-managed fields resulted in $32.00 to $74.10 ha-1 in 2007 and $44.46 to $66.50 ha-1 in 2008 in energy saving and additional net return to the farm income. The results from this study can have significant positive implications in future irrigation management of irrigated maize systems in regions with similar soil and crop management practices.", "keywords": ["Civil and Environmental Engineering", "0106 biological sciences", "571", "Environmental Engineering", "550", "Other Civil and Environmental Engineering", "2204 Biomedical Engineering", "1107 Forestry", "01 natural sciences", "630", "Engineering", "1102 Agronomy and Crop Science", "1106 Food Science", "1111 Soil Science", "2.

Field experiments were conducted in the 2011 and 2012 growing seasons to measure grain yield and quantify ETc, irrigation water use efficiency (IWUE), and crop water use efficiency (CWUE) as well as develop irrigation-yield production functions (IYPF) and evapotranspiration-yield production functions (ETYPF) for three PPDs and planting dates under subsurface drip irrigation and rainfed conditions in south central Nebraska. Plant growth and development indicators [leaf area index (LAI) and plant height] were quantified. Three PPDs [59,300, 74,100, and 88,900 plants per hectare (pph)] and three planting dates (May 4, 16, and 23 in 2011, and April 24, May 8, and May 17 in 2012) were implemented. Planting date and PPD had mixed effects on ETc, which ranged from 423 to 577 mm under irrigated conditions and from 355 to 501 mm under rainfed conditions. In 2011 under irrigated conditions, maize ETc increased with delaying the planting date under 59,300 PPD, while it decreased with delaying the planting date under 88,900 PPD. Under 74,100 PPD, the lowest ETc of 507 mm was observed for the 2nd planting (May 16), and the highest ETc of 563 mm was observed under late planting in 2011. In 2012, ETc varied from 466 to 577 mm under irrigated conditions and from 355 to 501 mm under rainfed conditions. Maize ETc decreased with delaying the planting date under 88,900 PPD, and the May\u00a08 planting resulted in the lowest ETc under 74,100 PPD. The 59,300 PPD had the highest ETc with the May 8 planting. Based on the pooled data of all PPDs, every 10-day delay (relative to the 1st planting) in planting date in a wet year (2011) did not affect ETc and resulted in only a 1 mm increase in ETc (ETc = 0.0746 x DOY + 505.53), whereas in a dry year (2012) every 10-day delay resulted in a substantial increase in ETc of 26 mm (ETc = 2.5887 x DOY + 134.87) beyond the intercept. Overall, grain yield increased with increasing PPD relative to the 1st planting by 15.9%, 12.2%, and 12.7% for 59,300, 74,100, and 88,900 PPD, respectively, under irrigated conditions and by 7.7%, 2.9%, and 5.6% for the same PPDs, respectively, under rainfed conditions. Overall, the impact of planting date on grain yield varied with the PPD and year and with rainfed or irrigated conditions. However, in general, each one-day delay in the planting date (from May 4) resulted in an average yield increase of 0.043 ton ha-1 (yield = 0.0428 x DOY + 7.3104) in a wet year (2011), and each one-day delay in the planting date in 2012 (from April 24) resulted in an average yield increase of 0.056 ton ha-1 (yield = 0.0555 x DOY + 2.4753) beyond the intercept. In the dry year, the late planting under rainfed conditions resulted in a substantial yield decrease with increasing PPD, with 16% and 10% yield reductions under the 74,100 and 88,900 PPDs, respectively, relative to 59,300 PPD. IWUE varied from 1.20 kg m-3 for the 1st planting with 88,900 PPD to 5.12 kg m-3 for the 3rd planting with 88,900 PPD in 2011, and from 1.63 kg m-3 for the 1st planting with 59,300 PPD to as high as 5.22 kg m-3 for the 1st planting with 74,100 PPD in 2012. In both years, CWUE values were very similar between treatments, ranging from 2.27 kg m-3 for the 3rd planting with 59,300 PPD to 2.81 kg m-3 for the 1st planting with 59,300 PPD. The IYPF and ETYPF exhibited intra-annual and inter-annual variation between planting dates and planting densities.", "keywords": ["0106 biological sciences", "2.
