Purdue Agronomy Farm Corn Cultural Practices (791803)

10.4231/R72B8VZN

Craig S. T. Daughtry

04/06/2015

The objectives of this experiment are to determine (1) the threshold of early season spectral detection of corn, (2) the spectral response of corn as a function of growth and amount of vegetation, and (3) the effect of soil background differences, particul...

Purdue Agronomy Farm Corn Moisture Stress (791801)

10.4231/R7DF6P5N

Craig S. T. Daughtry

04/22/2015

Differences in moisture availability account for much of the variation from year to year in corn yields. This experiment was a limited study of the effects of deficits in plant available moisture on the spectral characteristics of corn canopies. Three leve...

Purdue Agronomy Farm Corn Nitrogen (791802)

10.4231/R7NZ85MC

Craig S. T. Daughtry

04/22/2015

Nitrogen fertilization is one of the primary factors responsible for the increased yields in the United States in the past 15 years. Four levels of fertilization, 0, 67, 134, and 202 kg/hectare, providing a range from distinctly deficient to abundant have...

Purdue Agronomy Farm Winter Wheat (801806)

10.4231/R7736NTR

Craig S. T. Daughtry

04/06/2015

This experiment was a continuation of the 1979 Winter Wheat Experiment. The purpose was to investigate the effects of disease and nitrogen fertilization on the spectral and agronomic characteristics of winter wheat. There were three nitrogen fertilizer rat...

Purdue Agronomy Farm Winter Wheat Disease (801805)

10.4231/R73B5X3F

Craig S. T. Daughtry

04/06/2015

The purpose of this experiment was to investigate the effects of disease (rust) on the spectral response of winter wheat. There were two disease treatment levels with three replications. Each plot was 6 meters square. Measurement of reflectance and radiant...

Purdue Agronomy Farm Calibration (801808)

10.4231/R70K26HG

Craig S. T. Daughtry

04/30/2015

This calibration test took place in 1980. 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 fi...

Purdue Agronomy Farm Other Crops (801809)

10.4231/R7R20Z9S

Craig S. T. Daughtry

04/06/2015

The purpose of this experiment was to obtain data for crops other than corn, soybeans, and winter wheat which may have similar spectral characteristics. The other crops plots were those used by other researchers at the Agronomy Farm which were near the cor...
