Title
The development of a crop specific drought index for winter wheat
Johann Booysen Lincoln (University of Nebraska) 1987
Other claims from this paper (7)
- Method / resource The CERES model estimated leaf area index remarkably well in winter wheat.
- Method / resource All models performed unsatisfactorily on estimated tiller numbers in winter wheat.
- Method / resource Soil moisture analysis gave acceptable model performance in winter wheat.
- Method / resource The CSDI showed definite advantages over PDSI when compared to crop performance.
- Association Small gains in model accuracy result in larger gains in CSDI accuracy for winter wheat.
- Observation Coefficients of determination from the 22 year analysis at North Platte were low.
- Method / resource The CSDI concept can be applied to other crops and has greater potential than PDSI or Crop Moisture Index for drought monitoring.
