Purdue Agronomy Farm Soybean, Potassium, and Phosphorous (781804)

10.4231/R75X26VZ

Craig S. T. Daughtry

04/21/2015

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 soybeans. Plots for data collection were selected from a long term experiment. Measurements of...

Purdue Agronomy Farm Soybean Management (781805)

10.4231/R7TH8JNF

Craig S. T. Daughtry

05/04/2015

The purpose of this experiment was to examine the effect of important cultural/management practices on the reflectance of soybeans. The treatments (cultural practices) included row width, cultivar, and population. Measurements were made at approximately 10...

Purdue Agronomy Farm Corn Nitrogen (781802)

10.4231/R7SQ8XBQ

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 Soybean Row Direction (791810)

10.4231/R7222RQ7

Craig S. T. Daughtry

05/04/2015

The objective of the experiment is to determine the effect of rows and row direction, variables in the area of cultural practices, on the reflective response of a soybean canopy as a function of azimuth and zenith sun angles. The design of the experiment i...

Purdue Agronomy Farm Instrument Altitude (791811)

10.4231/R75T3HFN

Craig S. T. Daughtry

05/05/2015

The object of the experiment is to determine how the canopy reflectance varies as a function of height above the crop and, particularly, what minimum height is needed to acquire repeatable reflectance measurements. Data were acquired on three canopies, mat...

Purdue Agronomy Farm Soil Background (791807)

10.4231/R74X55R1

Craig S. T. Daughtry

04/22/2015

The purpose of this experiment was to determine the effects of soil background (soil color, soil moisture, soil roughness) on the spectral response of corn. The treatments were: 2 surface moisture levels (moist and dry) 2 surface tillage conditions...

Purdue Agronomy Farm Other Crops (791809)

10.4231/R7K07263

Craig S. T. Daughtry

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 Winter Wheat (791806)

10.4231/R7639MPC

Craig S. T. Daughtry

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...
