CONCLUSIONS 
Symp> 
1. Black and white multispectral aerial photography 
(MSP) is an appropriate technique for the frequent 
acquirement of remotely sensed data in agricultural 
research. 
TUR 
2. Reflectance values obtained by MSP could be used 
for ascertaining differences in crop response due to 
different treatments. Results for reflectances were 
consistent when comparing results of successive grow 
ing seasons. The reflectance values in an infrared 
band were particularly outstanding for ascertaining 
treatment differences.

3. If LAI was estimated by reflectance values, by 
using a regression curve of LAI on corrected infra 
red reflectance, the critical levels in testing for 
treatment differences were in general smaller than 
those for the measured LAI of samples, indicating 
a larger power for the estimated LAI. This also ap 
plied to the coefficients of variation.
