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 …

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) …
