Mixed model with spatial variance–covariance structure for accommodating of local stationary trend and its influence on multi-environmental crop variety trial assessment
consistency ratio test wheat barley
2014/10/23
The most common procedure for analyzing multi-environmental trials is based on the assumption that the residual error variance is homogenous across all locations considered. However, this may often be...
Spatial variation of carbon dioxide fluxes in corn and soybean fields
Spatial Variation Transects Soil Organic Matter
2013/3/4
Spatial variation of soil carbon dioxide (CO2) flux during a growing season within corn and soybean canopies has not been quantified. These cropping systems are the most intense in the United States a...

Temporal and Spatial Variations of Carbohydrate Content in Rice Leaf Sheath and Their Varietal Differences
Carbohydrate Enzyme Leaf sheath Spatial variation Temporal change Variety
2009/7/27
In rice plant, carbohydrates accumulated in leaf sheaths before heading are translocated to grain and affect yield formation greatly. To clarify the intrinsic mechanism of carbohydrate metabolism in t...
Spatial Distribution of Leaf Area Index and Leaf N Content in Relation to Grain Yield and Nitrogen Uptake in Rice
Grain yield Leaf area index Leaf N content N uptake Spatial distribution
2009/7/23
Exploring approaches to optimizing spatial distributions of leaf area index (LAI) and leaf nitrogen content (LNC) should be useful for increasing grain yield in rice (Oryza sativa). The primary object...
Analysis of the Spatial Heterogeneity of Wheat Yield Based on Complex Adaptive Systems' Approach
complex adaptive system field experiment wheat
2010/12/2
Twelve experimental sections of 4 rows×3m were established to examine the heterogeneity of a 72-a wheat field. Using 20 sample yield values from each experimental section, the heterogeneity of the fie...
