Abstract
An attempt to derive a relation between spectral data of rice canopies and their grain yield has been made in the Cuttack and Puri districts of Orissa for Kharif rice using Landsat MSS digital data of three years (1984-1986). Necessary sensor-to-sensor transformations of Landsat MSS to IRS LISS-I and acquisition date normalization with respect to a typical rice growth profile were also carried out, Using such an empirical relation, rice yield was estimated for Kharif in 1988 using IRS-IA LISS-I data at district level. Deviation of the estimated yields from the reported figures varied from 2 per cent to 14 per cent at the district-aggregated level.Keywords
