Computers and Electronics in Agriculture

Highlights

• This study demonstrates a minimalist Bayesian dynamic crop modeling framework.

• The framework enabled estimation of parameters and their uncertainties.

• Inclusion of a water balance shifted parameter estimates.

Field Crops Research​

Highlights

• We propose a yield-protein plasticity framework to assess G × N interactions.

• Yield associated with yield plasticity in high yield non-N limiting environments.

• Yield plasticity was unrelated with grain protein.

• Protein plasticity associated negatively with yield.

• Harvest index associated with yield plasticity in high yielding environments.

Crop Science

Highlights

• High-input management reduced wheat yield gap and improved milling and baking attributes.

• E was the largest driver of yield and milling and baking qualities, followed by M and lastly by G.

• Fungicide application improved yield and grain characteristics related to milling (grain weight, test weight).

• Higher N rates improved yield as well as flour and dough characteristics related to baking (protein, stability).

Agronomy Journal

Highlights

• Irrigated wheat yield reduced by 11%–22% due to above flag leaf and 32%–52% below flag leaf hail damage.

• Hail early at flowering stage decreased yield by 50%–70% in the rainfed low yielding environment (LYE).

• Hail late after flowering stage decreased yield by 20%–50% in rainfed LYE.

• Hail damage was mainly dependent on the canopy position in irrigated wheat.

• Hail damage was mainly dependent on growth stage in rainfed wheat at LYE.

Agronomy Journal

Highlights

• Crop rotations outyielded continuous cropping, with a greater advantage in no-till systems.

• Yield performance and stability of no-till decreased under continuous cropping.

• Soybeans following wheat or sorghum outyielded continuous crop in low- and high-yield environments, respectively.

• Continuous no-till wheat had the greatest yield penalty among the three crops evaluated.

• Soil organic carbon increased over time with no-till but did not change with conventional tillage.

Field Crops Research

Highlights

• Wheat water-limited wheat yield (Yw) in the southern Great Plains averages 5.2 Mg/ha.

• Yw increases from 3.5 Mg/ha in the west to 6.5 Mg/hain the east.

• Growing season water supply explains 82% of the Yw variability in the west.

• Post-anthesis solar radiation explains 73% of the Yw variability in the east.

• Maximum water productivity averages 17.2 kg/ha/mm.
