Purdue Agronomy Farm Corn Nitrogen (781802)
10.4231/R7SQ8XBQ
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 Corn Potassium and Phosphorous (781803)
10.4231/R7F769HT
05/04/2015
The purpose of this experiment was to examine the effects of different levels of soil phosphorous and potassium on the reflectance and radiant temperatures of corn. Plots for data collection were selected from a long term experiment. Measurements of ref...

Purdue Agronomy Farm Other Crops (791809)
10.4231/R7K07263
05/05/2015
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...

Purdue Agronomy Farm Corn Leaf Blight (791805)
10.4231/R7PR7SXQ
05/04/2015
The purpose of this experiment was to investigate the effects of a non-systematic fungus disease, southern corn leaf blight (Helminthosporium maydis), on the multispectral reflectance and radiant temperature of corn. Southern corn leaf blight is an example...

Purdue Agronomy Farm Winter Wheat (791806)
10.4231/R7639MPC
04/06/2015
The purpose of this experiment is to investigate the effects of disease and nitrogen fertilization on the spectral and agronomic characteristics of winter wheat. There were three nitrogen fertilizer rates (0, 46, and 92 kg/hectare), and three disease treat...

Purdue Agronomy Farm Soybean Cultural Practices (791804)
10.4231/R79W0CDB
04/06/2015
The objectives of this experiment are to determine (1) the threshold of early season spectral detection of soybeans, (2) the spectral response of soybeans as a function of growth and amount of vegetation, and (3) the effect of soil background differences,...

Purdue Agronomy Farm Corn Moisture Stress (791801)
10.4231/R7DF6P5N
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...
