Crop yield maps reflect stable yield patterns and annual random yield variation. Procedures for classifying a sequence of yield maps to delineate yield zones were evaluated in two irrigated maize (Zea mays L.) fields. Yield classes were created using empirically defined yield categories or through hierarchical or nonhierarchical cluster analysis techniques. Cluster analysis was conducted using average yield (MY), average yield and its standard deviation (MS), or all individual years (AY) as…

Factors underlying yield variability in two California rice fields

The clustering procedure successfully identified stable, physically meaningful clusters with recognizable spatial and temporal structure and the randomization procedure may present an attractive alternative to fuzzy clustering.

Spatial and Temporal Trends of Irrigated Cotton Yield in the Southern High Plains

Understanding spatial and temporal variability patterns of crop yield and their relationship with soil properties can provide decision support to optimize crop management. The objectives of this

Corn yield variability on the Des Moines Lobe of Iowa: Assessment of extent and soil-related causes

Precision agriculture techniques are an essential component to modern row crop agriculture in Iowa and can be used to create crop yield variability maps via geographic information systems. The first

Assessing the temporal stability of spatial patterns in crop yields using combine yield monitor data

Using previous years’ yield patterns may be one method of breaking a field into management zones for the purpose of site-specific management. For this method to be useful there must be temporal

Screening Yield Monitor Data Improves Grain Yield Maps

Yield monitor data contain systematic and random errors, which must be removed for creating accurate yield maps. A general procedure for assessing yield data cleaning methods was applied to a new

Patterns of Regional Yield Stability in Association with Regional Environmental Characteristics

Among eight partial least squares regression models, which explained 50 to 81% of variation of mean yields and yield CVs, mean organic matter and mean depth to seasonally high water table had greatest relative importance to mean yields of grass crops and legume crops, respectively.

The application of various software programs for mapping yields in precision agriculture

Yields mapping can be done in GIS programs as well as in specialized software for agriculture. These can be programs designed for preparing informative and application maps and also software designed

Year patterns of climate impact on wheat yields

Rainfall, temperature, and solar radiation are important climate factors, which determine crop growth, development and yield from instantaneous to decadal scales. We propose to identify year patterns

Profitability Maps as an Input for Site‐Specific Management Decision Making

For over a decade, farmers have been collecting site-specific yield data. Many have formed doubts about this investment because of their inability to directly apply this information as feedback for




Consistent spatial–temporal yield patterns should help determine spatial production potential. Our objective was to evaluate methods for using yield monitor data to develop spatial yield goal maps.

Spatial and temporal stability of corn grain yields

Year-to-year consistency of crop yields within a farm field is needed to use grain yield monitor data for site-specific management decisions such as yield goals for fertilizer recommendations. A 5-yr

Spatial and temporal variability of corn grain yield on a hillslope

The purpose of this study was to relate the temporal and spatial variability of corn (Zea mays L.) grain yield on a Typic Fragiochrept soil on a hillslope to soil properties and topographic features.

Spatiotemporal variability of corn and soybean yield

Little is known about the spatial structure of yield across fields, nor of the temporal stability of this structure. We determined the spatial structures of grain yield for 6 yr of data and examined

An Evaluation of the Response of Yield Monitors and Combines to Varying Yields

Comparisons were made between yield measurements with an impact based yield sensor and an electronic scale in adjacent harvest strips and on the same grain stream within a combine. Yield measurements
