Conclusion 
This study demonstrates the importance of multi-temporal SAR 
data in the retrieval of transplantation date in case of rainfed 
rice environment. The transplantation date is considered to be 
an important parameter in case of rice crop monitoring. The 
progress of transplantation pattern over a particular area can act 
as an important input for crop management practices, cropping 
system analysis as well as for generating crop calendar. The 
generation of transplantation date map of rice area progres- 
sively throughout the season has been found advantageous, 
which enables to predict the behaviour of rice growing areas as 
well as rice growth conditions.
