LTAR - Meteorological Stations - Walnut Gulch Experimental Watershed

The SWRC operates the Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona as an outdoor laboratory for studying semiarid rangeland hydrologic, ecosystem, climate, and erosion processes.

WGEW is currently contributing meteorological data from 4 stations to the NAL data repository.

Product System Model of United States Poultry Production 2010

This product system represents the poultry meat produced for human consumption as a result of producing one broiler. Both types of live weight poultry are at the farm gate, ready for transport to the processing plant, although not necessarily at the same farm. It includes the fraction of a spent hen attributable to the production of one broiler.

Data from: Color Analysis of Storage Roots from the USDA, ARS Sweetpotato Germplasm Collection

The periderm (skin) and stele (flesh) of sweet potato storage roots were measured using a Konica Minolta Chroma Meter, and data were recorded using the CIE 1976 L*a*b* and CIE L*C*h* color spaces. Data parameters presented are lightness (L*), red-green coordinate (a*), yellow-blue coordinate (b*), color intensity or chroma (C*), and hue angle (H*). Also included in this data set are percentage dry matter and root densities as these data are correlated to color values.

Feed the Future Grain Legumes Project Database

Data from this project focuses on the evaluation of breeding lines. These breeding lines, derived from 109 PIC populations specifically developed to combine abiotic and biotic stress tolerance, showed superior agronomic potential compared with checks and local landraces. The diversity, scale, and potential of the material in the PIC breeding pipeline is invaluable and requires continued support to ensure the release of varieties that promise to increase the productivity of common bean in the E. African region. Data available includes databases, spreadsheets, and images related to the project.

International Food Security

This dataset measures food availability and access for 76 low- and middle-income countries. The dataset includes annual country-level data on area, yield, production, nonfood use, trade, and consumption for grains and root and tuber crops (combined as R&T in the documentation tables), food aid, total value of imports and exports, gross domestic product, and population compiled from a variety of sources.
