The Bronson Files, Dataset 4, Field 105, 2013

    Active optical proximal wheat canopy sensing spatial data and including additional related metrics such as canopy thermal and height are presented. Agronomic nitrogen and irrigation management related field operations are listed. Unique research experimentation intermediate analysis table is made available, along with the raw data. The raw data recordings, and annotated table outputs with calculated VIs are made available. Plot polygon coordinate designations allow a re-intersection spatial analysis. Data was collected in the 2013 season at Maricopa Agricultural Center, Arizona, USA. High throughput proximal plant phenotyping via electronic sampling and data processing method approach is exampled. Acquired data using USDA Maricopa first mobile platforms, such as the Proximal Sensing Cart Mark1, SAS and GIS compute processing output tables, including Excel formatted examples are presented, where data tabulation and analysis is available. The weekly proximal sensing data collected include canopy reflectance at six wavelengths, ultrasonic distance sensing of canopy height, and infrared thermometry. Ten levels gradient irrigation application from linear move sprinkler system were applied. Soil physical texture and fertility chemistry results are available. Yield and seed information is presented.

    Data from: Microbial volatile organic compounds mediate attraction by a primary but not secondary stored product insect pest in wheat

      This dataset is associated with the forthcoming publication entitled, "Microbial volatile organic compounds mediate attraction by a primary but not secondary stored product insect pest in wheat", and includes data on grain damage from near infrared spectroscopy, behavioral data from wind tunnel and release-recapture experiments, as well as volatile characterization of headspace from moldy grain.

      Comparison of four extractants used in soil phosphorus and potassium testing for two soils in a corn-wheat-soybean rotation in Tennessee receiving various amounts of P and K fertilizer

        These soil samples are from field experiments initiated in 2009. There were two separate fertilizer rate trials at each location, one for P and one for K, and each was implemented in a corn-winter wheat-soybean rotation. The soils used in this study are from University of Tennessee (UT)’s Research and Education Center at Milan (35.9, -88.73333) and UT’s Highland Rim Research and Education Center at Springfield (36.466667, -86.816667).

        Data from: Long-lasting insecticide-incorporated netting and interception traps at pilot-scale warehouses and commercial facilities prevents infestation by stored product beetles

          Data are presented from a study of the efficacy for insecticide netting and interception traps in pilot-scale and commercial food facilities. Excel files cover: Attraction Assessment; Dose Dependency Data; Spillage Trap Collections; Spillage Trap Progeny; Trial 1 Recapture; Trial 1 Progeny Production; Trial 2 Recapture; Trial 2 Progeny Production.

          Data from: A deletion mutation in TaHRC confers Fhb1 resistance to Fusarium head blight in wheat

            Fusarium head blight (FHB), which is mainly caused by *Fusarium graminearum*, is a destructive wheat disease that threatens global wheat production. *Fhb1*, a quantitative trait locus discovered in Chinese germplasm, provides the most stable and the largest effect on FHB resistance in wheat. Here we show that *TaHRC*, a gene that encodes a putative histidine-rich calcium-binding protein, is the key determinant of *Fhb1*-mediated resistance to FHB.

            De novo transcriptome assembly of Schizaphis gramium Biotype I feeding on wheat

              Transcriptome was generated from pooled adult aphids that were fed on wheat plants containing the Dn4 and DN7 resistance gene as well as Yuma plants containing no resistant genes (Dn0). The assembly was generated using Trinity. All assembled transcripts, including those that were not predicted to encode ORFs, are included along with their corresponding functional annotations from Trinotate.

              Global Land Analysis & Discovery (GLAD) Global Cropland Extent

                This study utilized 250m MODIS (MODerate Resolution Imaging Spectroradiometer) data to map global production cropland extent. A set of multi-year MODIS metrics incorporating four MODIS land bands, NDVI (Normalized Difference Vegetation Index) and thermal data was employed to depict cropland phenology over the period 2000-2008. The probability and discrete cropland/non-cropland data are available for download by MODIS tile at the full ~250m resolution or as global mosaics at ~1km resolution.

                Data from: Phylogeography of the Wheat Stem Sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae): Implications for Pest Management

                  The wheat stem sawfly is a key pest of wheat in the northern Great Plains of North America, and damage resulting from this species has recently expanded southward. The genetic divergence between samples collected in North America and northeastern Asia using two mitochondrial regions (COI and 16S) are examined. The structure of genetic diversity in the main wheat producing areas in North America are also characterized using a combination of mtDNA marker and microsatellites in samples collected both in wheat fields and in grasses in wildlands.
