“…The interaction of Span X Application method did not have a significant effect on WUE. Crop response to corn in Bushland was similar for corn grown near Garden City, KS, by Kisekka et al [5] under MDI. In the one-year study (2015), they also reported no significant difference in grain yields (1.56 kg m −2 and 1.60 kg m −2 ) and WUE (2.06 kg m −3 and 2.17 kg m −3 ) compared with LESA.…”

“…Olson and Rogers [6] and Kisekka et al [5] also reported this problem. To prevent tangling the MDI driplines with the crop when changing the direction of pivot travel, the pivot was moved into fallow ground for a distance that was at least the length of the inner driplines.…”

“…Kisekka et al [5] reported that water redistribution in the soil profile under MDI occurred in both the horizontal and vertical directions. In both years, near DOY 265 (approximately 100 DAP) soil water depletion was lowest for MDI treatment plots, indicating that more water was present in the soil profile when the crop reached maturity.…”

Mobile drip irrigation (MDI) technology adapts driplines to the drop hoses of moving sprinkler systems to apply water as the drip lines are pulled across the field. There is interest in this technology among farmers in the Texas High Plains region to help sustain irrigated agriculture. However, information on the performance of this system and its benefits relative to common sprinkler application technologies in the region are limited. A two-year study was conducted in 2015 and 2016 to compare grain yields, crop water use (ET c ) and water use efficiency (WUE) of corn (Zea Mays L.) irrigated with MDI, low elevation spray application (LESA) and low energy precision application (LEPA) methods. Irrigation amounts for each application method were based on weekly neutron probe readings. In both years, grain yield and yield components were similar among application treatment methods. Although WUE was similar for the MDI treatment plots compared with LEPA and LESA during the wet growing season (2015), MDI demonstrated improved WUE during the drier year of 2016. Additional studies using crops with less than full canopy cover at maturity (sorghum and cotton) are needed to document the performance of MDI in the Texas High Plains region.Keywords: center pivot; corn water productivity; precision irrigation; sprinkler irrigation; surface drip irrigation Disclaimer: The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or part of an individual's income is derived from any public assistance program.

Negative pressure irrigation on water use efficiency, yield and quality of Brassica chinensis L.

et al. 2021

View full text Add to dashboard Cite

BACKGROUND: Water is critical to the production of crops, especially when faced with seasonal drought or freshwater scarcity. We compared the effect of negative pressure irrigation (NPI) on water use efficiency (WUE), nutrient uptake, yield and quality of Brassica chinensis L. using a greenhouse plot experiment. Three different water supply pressures (−5, −10 and −15 kPa), and a conventional irrigation (CK) treatment, were arranged in a randomized design with three replications. RESULTS: Our results suggest that plant height, leaf area, number of leaves and ratio of root to shoot were significantly correlated with water supply pressure. Specifically, our results show that B. chinensis L. yield was increased 50% with NPI versus CK. Water supply pressure had a significant effect on N and P nutrient uptake and no significant effect on K. The average concentration of vitamin C was greatest with −5 kPa treatment and consecutively declined. According to our results, NPI can save up to 36.8% of water used and improve WUE by 61.3% during growth of B. chinensis L. Our results suggest that the optimum irrigation management strategy is −5 kPa treatment.CONCLUSION: NPI versus CK can provide more stable irrigation water and retain soil moisture during plant growth, resulting in an increased WUE and yield with suitable water supply pressure. While our results suggest that NPI can enhance B. chinensis L. yield and perhaps also quality, future research should explore the mechanism of NPI in relation to yield and water use efficiency.
