Mobile Drip Irrigation Evaluation In Corn, I. Kisekka, T. Oker, G. Nguyen, J. Aguilar, D. Rogers
Kansas Agricultural Experiment Station Research Reports
Mobile Drip Irrigation (MDI) involves attaching driplines to center pivot drops. MDI has potential to eliminate water losses due to spray droplet evaporation, water evaporation from the canopy, and wind drift. MDI also may reduce soil water evaporation due to limited surface wetting. A study was conducted with the following objectives: 1) compare soil water evaporation under MDI and in-canopy spray nozzles; 2) evaluate soil water redistribution under MDI at 60 inch dripline lateral spacing; 3) compare corn grain yield, water productivity, and irrigation water use efficiency; and 4) compare end-of-season profile soil water under MDI and in-canopy spray at …
Sorghum Yield Response To Water Supply And Irrigation Management, I. Kisekka, F. Lamm, A. Schlegel
Sorghum Yield Response To Water Supply And Irrigation Management, I. Kisekka, F. Lamm, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
Grain sorghum yield, under full and limited irrigation, was evaluated at three locations in western Kansas (Colby, Tribune, and Garden City). The top-end yield under full irrigation was 190 bu/a. However, there were no significant differences among irrigation treatments at all the three locations due to the above normal rainfall received during the 2015 growing season. These preliminary results indicate that there is potential to improve grain sorghum yields under limited irrigation. Additionally, best management practices to maximize kernels per head could have the greatest effect on grain yields.

There is limited information on forage sorghum and corn silage yield response to full and deficit irrigation in Kansas. The objective of this study was to generate information on forage sorghum (brown mid-rib hybrids (BMR and non-BMR)) and corn silage yield response to different levels of irrigation as influenced by irrigation capacity in southwest Kansas. Preliminary results indicate the effect of irrigation capacity on forage yield was significant (P = 0.0009) in 2014 but not 2015, probably due to high growing season rainfall received in 2015. Corn silage produced significantly (p<0.05) higher biomass at all irrigation capacities compared to forage sorghum hybrids in 2015. BMR forage sorghum produced significantly lower biomass compared to non-BMR hybrid in both 2014 and 2015 (P<0.05). The highest amounts of forage produced for corn silage, BMR, and non-BMR forage sorghum were 24.6, 17.4, and 21.1 tons/a adjusted to 65%, moisture respectively. Water productivity ranged from 1.0 to 1.4 dry matter tons/a/in. More research is needed under normal and dry years to quantify forage sorghum and corn silage yield and forage quality response to full and deficit irrigation.
Alternative Cropping Systems With Limited Irrigation, A. Schlegel
Alternative Cropping Systems With Limited Irrigation, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
A limited irrigation study involving six cropping systems was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The cropping systems were two annual systems (continuous corn [C-C] and continuous grain sorghum [GS-GS]) and four 2-year systems (corn-sorghum [C-GS]), corn-sunflower [C-SF], corn-winter wheat [C-W], and corn-wheat/double sunflower [C-W/SF]). In 2015, corn yields were lower following corn than other crops while wheat and grain sorghum yields were similar for all rotations. This tended to agree with the 3-year average yields except for average sorghum yields being higher following corn than sorghum. Sunflowers were destroyed by rodents and no yields …

In 2015, annual precipitation of 21.72 in. was recorded, which is 3.82 in. above normal. Seven months had above-normal precipitation. May (6.16 in.) was the wettest month. The largest single amount of precipitation was 1.86 in. on July 20. December, the driest month, only recorded 0.08 in. of precipitation.

The purpose of this study was to evaluate the response of two commercial hybrids (DKC 62-27 DGVT2PRO [drought tolerant trait (DT)] and DKC 62-98 VT2PRO [conventional]) to limited irrigation. Preliminary results from the 2014 and 2015 growing seasons at Southwest Research-Extension Center near Garden City, Kansas, indicate the effect of irrigation capacity on corn yield was significant (P<0.001)for both hybrids. The effect of the drought tolerance trait on yield was not significant (P>0.05)in both years. The effect of the interaction between irrigation capacity and corn hybrid on yield was also not significant (P>0.05) …0.001)

Precipitation for 2015 totaled 23.27 in. This was 4.03 in. above the 30-year average of 19.24 in. and was nearly identical to 2014. Significant blowing dust was not observed in 2015. May and July had notably high precipitation with 6.38 in. and 5.36 in., respectively, which nearly doubled normal precipitation for these months. Hail was not observed in 2015. The largest daily rainfall was 1.94 in. on October 22. Sixteen days in May recorded measurable moisture.
