Title: Mobile Drip Irrigation Evaluation in Corn
Excerpts:
The experiment was conducted at the Kansas State University Southwest Research-Extension Center near Garden City, Kansas. Soil water evaporation was measured using four-inch mini lysimeters.
- compared soil water evaporation under MDI and in-canopy spray nozzles to evaporation in MDI lower than spray
- evaluated soil water redistribution under MDI at 60-inch dripline lateral spacing
- compared corn grain yield, water productivity, and irrigation water use efficiency
- In general, no significant difference
- At 600 gpm: spray nozzles corn yields > MDI corn yields
- At 300 gpm: MDI corn yields >spray nozzles corn yields
- compared end-of-season profile soil water under MDI and in-canopy spray at two well capacities 300 and 600 gpm
- Mobile Drip Irrigation soil water > in-canopy spray nozzles soil water in the 8 foot.

Title: Evaluating Soil Water Redistribution under Mobile Drip Irrigation, Low-Elevation Spray Application, and Low-Energy Precision Application Using HYDRUS
Excerpts:
The experiment was conducted at the K-State SW Research-Extension Center near Garden City, Kansas
- MDI driplines and LEPA showed the highest lateral soil water redistribution
- The mean soil water contents for MDI1, MDI2, LEPA, and LESA at a depth of 30 cm were 0.31, 0.31, 0.31, and 0.33 cm3⋅cm−3 respectively
- The results indicated greater nonuniformity under MDI than under LESA.
- The results also showed that the MDI water redistribution pattern was similar to that of LEPA, but horizontal uniformity was less than with LESA.
- MDI had 48% and 19% less runoff potential compared with LEPA and LESA, respectively.
- Soil water redistribution uniformity under MDI was less than under LESA and LEPA, it enabled better infiltration and lessened runoff potential

Title: EVALUATION OF MOBILE DRIP IRRIGATION (MDI) AND OTHER SPRINKLER PACKAGES
Excerpts:
The experiment was conducted in different farms
- The yield data in 2016 at the SWREC plots showed that there was barely any difference between the MDI treatments, bubbler and sprays at the higher well capacities (600 and 300 gpm).
- At the 600 gpm, spray seem to have a significant advantage with the MDI with 2gpm hose. However, at the 150 gpm well capacity, the spray did show a significant disadvantage or yield penalty compare with most of the other treatments.
- In 2016, the center pivots in the fields incurred substantial repair costs particularly related to wheels and wheel drive train.
- If one considers the profit above variable expenses, there is slight advantage in using the MDI ($366 and $478) compared with spray nozzles ($351 and $475). However, if you consider the water use in the computation, then the profit per acre-inch per acre now becomes favorable for spray.
- The hose has consistently had the lowest yield while the bubbler had consistently higher yields.
- By reduced the application rates in the MDI by 20 and 30 percent, the MDI did suffer yield losses. However, the water use efficiency was greater in the MDI compared with the spray.
- The bubbler package did have the lowest yield and the fixed spray had the highest yield in most instances and new introduced i-wob package was in between. However, the reason of these result could be the run-offs that come from the others span since the field had slope.
- In the flat farms, the bubbler package, i-wob and fixed spray did have the highest yield respectively

Title: Mobile Drip Irrigation for Water Limited Crop Production: Initial Results
Excerpts:
- Soil water evaporation was lower under MDI compared to LESA by an average of 35%.
- Soil water was greatest at the mid-point between two drip line laterals spaced 60 inches apart at a depth of approximately 20–24 inches that indicate drip line spacing of 60 inches is adequate for silt loam soils of southwest Kansas.
- The effect of irrigation application method (MDI versus spray nozzles [LESA]) on yield at high (600 gpm) and low (300 gpm) well capacities was not statistically significant.
- The effect of application method on water productivity and irrigation water use efficiency was not significant.
- Under low well capacity (300 gpm), mobile drip irrigation had more soil water compared to spray nozzles.

Title: Evaluation of maize production under mobile drip irrigation
Excerpts:
The experiment was conducted at the K-State SW Research-Extension Center near Garden City, Kansas
- Differences in grain yield between irrigation application devices were not significant, but there were differences between irrigation capacities.
- There were no significant differences in monthly biomass yield between the application devices but there were significant differences in biomass yield between irrigation capacities.
- There were no significant differences in LAI between both the application devices and irrigation capacities.
- There were no significant differences in water use efficiency between the application technologies, however, differences between irrigation capacities were significant
- Generally, crop biophysical measurements under MDI were not significantly different from those under LEPA and LESA
- Any marginal benefits of MDI were likely masked by rainfall, thus further evaluation of MDI is recommended under conditions of less applied water than LEPA or LESA accompanied by low rainfall.

Title: Comparing Mobile Drip Irrigation to Low Elevation Spray Application in Corn
Excerpts:
The experiment was conducted at SW Research-Extension Center near Garden City, Kansas
- Results indicate grain yield was not significantly different between MDI and LESA due to the above normal rainfall received during the 2015 growing season .
- The effect of application method on water productivity and irrigation water use efficiency was also not significant.
- Water productivity and irrigation water use efficiency were higher under the 300 gpm study compared to the 600 gpm, implying that water was used more efficiently as the number of irrigation applications decreased.

Title: Economic feasibility of conversion to mobile drip irrigation in the Central Ogallala region
Excerpts:
Compared MDI and LESA
- Using a 3% discount rate, under the medium level of investment cost ($371 per hectare), a discounted payback period of 4.9, 9.0, and 6.3 years is required for corn, cotton, and sorghum/wheat, respectively.
- As the cost per hectare to convert an existing center pivot drops to $185 per hectare, the payback period also drops to 2.3, 4.2, and 3.0 years, respectively.
- producers growing higher water use crops are able to recover the costs of the conversion to MDI through increased water use efficiency quicker than producers growing medium and lower water use

Title: Mobile Drip Irrigation Transforming Center Pivots Through Drip Technology
Excerpts:
- By replacing the sprinkler systems of a center pivot with lines of tubing with drip emitters, application efficiency can be improved to levels that are comparable to subsurface drip irrigation.
- Evaporative loss of irrigation water after being applied to the soil surface are also reduced with trials showing up to 35% reduction in evaporation with MDI when compared to traditional nozzles.
- Mobile Drip Irrigation systems can operate at pressures as low as 68 kPa (10 PSI) and have great success with low-capacity water.
- Mobile drip irrigation has shown the ability to decrease pumping costs, reduce runoff of water, decrease rutting of wheel tracks by the drivelines of pivots, as well as reduce wear on mechanical parts of the pivot when compared to traditional sprinklers.
- With comparable efficiency to subsurface drip irrigation at a lower price point, and the fact that it can adapted to existing irrigation systems, MDI has been shown to be an effective system on a variety of crops and in multiple regions of the world as it can be customized to fit the operation needs.

Title: CENTER PIVOT PRECISION MOBILE DRIP IRRIGATION
Excerpts:
The experiment was conducted at Hoxie, KS at DLS Farms.
- There was no positive or negative impact on yield from those plots that were irrigated with the PMDI system versus a standard drop nozzle system.
- Emitter flow was decreased in PMDI compared with nozzle flow which was likely due to emitter clogging.
- Clogging of the emitters over the life of the system along with puncturing of the hoses from wildlife appear to be two negatives of the system, while one benefit of the system was the reduced wheel pivot tracks when the PMDI system is used to water crops near the pivot wheel.
