Project Title:
Locus Ag industry trial in spring wheat
Objective:
To test different Locus Ag treatments for quality and yield for spring wheat.
Personnel:
J.A. Torrion, Daniel Porter
Summary:
WB9668 (Westbred) hard spring wheat was planted with the three Locus treatments and a grower practice as a check on two different locations: 1) rainfed silt-loam soil with subsurface recharge and 2) rainfed fine sandy loam soil. The management is shown in Table 1.
All the parameters observed were not significant for both studies. In study 1 with subsurface recharge (Table 3), yield and protein were low compared with the drier environment in Study 2 (Table 4). Study 1, with subsurface recharge, was flooded during the vegetative stage from runoff. We anticipated that there was significant nitrogen loss in this location, thus, with also low protein.
