Maintenance breeding and breeding for yield potential equally contribute to genetic improvement in wheat yield Open
Studies that quantify the contribution of genetic improvement to crop yields typically rely on comparisons of old cultivars grown side-by-side with more recent ones. This approach, however, does not allow to distinguish gains in yield pote…

Predicting spatial and temporal variability in soybean yield using deep learning and open source data Open
Spatial crop yield prediction provides valuable insights for supporting sustainable and precise crop management decisions. This study assessed the capabilities of advanced Deep Learning (DL) architectures in predicting within-field soybean…

The inadequacy of statistical approaches to estimate yield potential and gaps at regional level Open
Spatial information on yield potential is key to determine crop production potential on existing cropland. Although statistical methods are widely used to estimate yield potential and yield gaps at regional to global levels, a rigorous eva…

Agronomy explains large yield gaps in smallholder oil palm fields Open
Palm oil production is a major source of income for millions of smallholders in Indonesia. However, actual yield remains low in relation to the attainable yield. While emphasis has been given to planting material as a factor explaining low…

Southeast Asia must narrow down the yield gap to continue to be a major rice bowl Open
Southeast Asia is a major rice-producing region with a high level of internal consumption and accounting for 40% of global rice exports. Limited land resources, climate change and yield stagnation during recent years have once again raised…

Spatial frameworks for robust estimation of yield gaps Open
Food security interventions and policies need reliable estimates of crop production and the scope to enhance production on existing cropland. Here we assess the performance of two widely used ‘top-down’ gridded frameworks (Global Agro-ecol…

Combining field-level data and remote sensing to understand impact of management practices on producer yields Open
Producer field-level data have been used in recent studies to identify suites of management practices that consistently increase yield for a given climate-soil environment. However, the physiological drivers underlying the empirical associ…

Management strategies for early‐ and late‐planted soybean in the north‐central United States Open
It is widely recognized that planting soybean [ Glycine max (L.) Merr.] early is critical to maximizing yield, but the influence of changing management factors when soybean planting is delayed is not well understood. The objectives of this…

Do shallow water tables contribute to high and stable maize yields in the US Corn Belt? Open
Shallow water tables (WT) can buffer against transitory rain-free periods leading to higher and more stable yields in rainfed crops. However, little is known about their influence on regional crop production and its stability. In the prese…
View article: Water productivity of rainfed maize and wheat: A local to global perspective
Water productivity of rainfed maize and wheat: A local to global perspective Open
Water productivity (WP) is a robust benchmark for crop production in relation to available water supply across spatial scales. Quantifying water-limited potential (WPw) and actual on-farm (WPa) WP to estimate WP gaps is an essential first …

Beyond the plot: technology extrapolation domains for scaling out agronomic science Open
Ensuring an adequate food supply in systems that protect environmental quality and conserve natural resources requires productive and resource-efficient cropping systems on existing farmland. Meeting this challenge will be difficult withou…

Sifting and winnowing: Analysis of farmer field data for soybean in the US North-Central region Open
Field trials are commonly used to estimate the effects of different factors on crop yields. In the present study, we followed an alternative approach to identify factors that explain field-to-field yield variation, which consisted of farme…
View article: Assessing causes of yield gaps in agricultural areas with diversity in climate and soils
Assessing causes of yield gaps in agricultural areas with diversity in climate and soils Open
Identification of causes of gaps between yield potential and producer yields has been restricted to small geographic areas. In the present study, we developed a novel approach for identifying causes of yield gaps over large agricultural ar…

From grid to field: Assessing quality of gridded weather data for agricultural applications Open
High quality measured weather data (MWD) are not available in many agricultural regions across the globe. As a result, many studies that dealt with global climate change, land use, and food security scenarios and emerging agricultural deci…
