The objective of this factorial experiment was to quantify the effects on spectral response of the major variables affecting wheat growth, development and yield. The factors and levels of each factor were: (1) Soil Moisture, Wheat and Fallow in 1976, (2) Variety: Olaf (semi-dwarf) and Waldron, (3) Nitrogen Fertilization: None and 39 lbs/acre, and (4) Planting Date: May 9 and 23.
This experiment was a continuation of the Spring Wheat North Dakota experiments for 1975 and 1976 and is also related to the Dryland/Irrigated Winter Wheat Experiments done at the Finney County, Kansas Agriculture Experiment Station during 1975, 1976, and 1977. These data were collected as a part of the LACIE Field Measurements Project. More information can be found in the LACIE Field Measurements Project Plan, 1976-77 and in the LACIE Field Measurements Data Library Catalog, Volume III, 1976-77 crop year.
The test took place in 1977.
The supporting docs include a brief summary of used instruments, a wavelength table (Wavelength_ASCII.txt), reflectance note and reflectance tables (ReflectanceTable206.txt and ReflectanceTableMulti.txt), and file format description (ExperimentDataFormat3.txt). The format description file is in ASCII format in lines of 80 characters.
This research dataset is part the Field Research Data Library that consists of over 200,000 spectral observations of soils and vegetation that have been collected since 1972 till 1991 as part of the research focused on vegetation and soils at the Laboratory for Applications of Remote Sensing (LARS) located at the Purdue University.
