Dear Bipin Kumar Pathak,

There a number of things that could cause this problem (the water balance
switch could be turned off, the dates for irrigation applications could
have been entered incorrectly, etc.).  Perhaps if you posted your .RIX file
to the list it would be easier to make a guess at the problem.
