The variable response of dryland corn yield to soil water content at planting
TLDR
In this article, the authors used linear regression to determine predictive relationships between dryland corn yield and available soil water at planting time and, if such a relationship exists, to use it to assess the risk in obtaining profitable yields.About:

Climate variation explains a third of global crop yield variability
TL;DR: This study uses detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide.

TL;DR: In this article, the authors used multilevel regression analyses of long-term crop yield datasets across a continental precipitation gradient to assess how temporal crop diversification affects maize yields in intensively managed grain systems.
Journal ArticleDOI
Interactions between temperature and drought in global and regional crop yield variability during 1961-2014.
TL;DR: Inter-annual crop yield variation is driven in large parts by climate variability, wherein the climate components of temperature and precipitation often play the biggest role, and the effect of temperature on yields might be underestimated in dry conditions.

Cover Crop Biomass Production and Water Use in the Central Great Plains
TL;DR: The water-limited environment of the semi-arid Central Great Plains may not produce enough cover crop biomass to generate benefits associated with cover crop use in more humid regions as mentioned in this paper.
Journal ArticleDOI
Intensification of dryland cropping systems for bio-feedstock production: Evaluation of agronomic and economic benefits of Camelina sativa
TL;DR: In this article, the benefits of growing camelina in rotation with winter wheat were evaluated in a replicated rotation study from 2008 to 2011 in the Northern Great Plains (NGP), focusing on the effects on wheat yield and overall profitability of the cropping system.

TL;DR: The paper outlines APSIM's structure and provides details of the concepts behind the different plant, soil and management modules, including a diverse range of crops, pastures and trees, soil processes including water balance, N and P transformations, soil pH, erosion and a full range of management controls.

Field-Measured Limits of Soil Water Availability as Related to Laboratory-Measured Properties
TL;DR: In this article, the field-measured limits were compared to laboratory measurements at −033 and −15 bar made on samples removed from each field site and a total of 401 observations were available for the comparisons of laboratory measurements to the field measured lower limits.

Efficient Water Use in Dryland Cropping Systems in the Great Plains
TL;DR: In this article, the authors reviewed research on water use efficiency and precipitation use efficiency as affected by cropping system and management in the semiarid Great Plains of North America and found that water use and PUE increase with residue management practices that increase precipitation storage efficiency, soil surface alterations that reduce runoff, cropping sequences that minimize fallow periods, and use of appropriate management practices for the selected crop.
