Abstract The increase in annually cropped area that has occurred in the eastern Pampas of South America (Uruguay) since 2002 was largely achieved by converting crop-pasture rotations to continuous annual no-till cropping systems. We studied the impact of this intensification on the attainable wheat yield (Yatt) and the yield gap (Yg), with the latter

Transfusion, 1997
BACKGROUND: Donor exposure risk and cost in platelet transfusion practice can be limited by increasing the recovery of platelets from donor units.STUDY DESIGN AND METHODS: This study presents results of continuous quality improvement efforts in platelet production and compares the in vivo therapeutic efficacy of currently produced platelet concentrates

Plant Disease
Damage functions, i.e., the relationships between crop yield loss (or relative yield loss) and disease injury provide pivotal quantitative knowledge to inform tactical and strategic decisions for disease management. Damage functions depend on the level of the attainable yield (Ya), i.e., on crop yield in absence of injury.

Climatic Change, 2018
As the growth in global population has led to greater demands for food and energy, societies have been pressured to increase food production. Closing the gap between current and potential yields is one means of producing more food. In this study, we first identify the gaps between the potential yield and actual on-farm yield of maize for ten climate ...
