Abstract
supernatural isolation of wheat, mustard and chickpea developed under variable water supply was done
by using hand held spectro-radiometer and infra-red thermometer. Red and infra-red reflectance from
the crop shade and shade thermal atmosphere through canopy-air temperature variation were recorded
at different stages of the crop development. Spectral indices, such as IR/R, Normalized Difference
Vegetation Index (NDVI) and Infrared-Red (IR-R, from the spectro-radiometric inspection) and growing
stress degree days were developed, which were consequently used to distinguish these crops through
Leaf Area Index (LAI), biomass and final grain yield. The three crops were spectrally variant between
themselves as well as inside each crop grown under discrepancy sequence of partial/moderate inputs of
water. This study, through development of transfer function for involving with satellite resulting indices,
can efficiently assist in operational satellite remote sensing for crops’ inequi
