| Abstract | In this study a computer model for predicting the
supplemental irrigation requirement of Aman rice in Bangladesh
has been developed. The model is based on simple water balance
principles which simulates the daily water balance during crop
season from transplanting to the drainage date.
With the developed model supplemental irrigation requirement
for critical stage (41 -70 DAT) of Aman rice was found to vary
from 0-200mm with an average of 70 - 75mm for one irrigation only.
The total irrigation requirements for Aman rice was found
to vary from 200 - 5OOmm with 2-9 number of irrigation which
averages to 4 irrigation in a season.
It has also been found that most or the areas of Bangladesh
have the potential or meeting atleast 50% or irrigation needs of
the critical stage (41-70 DAT)by the runoff water of initial
stage (1-40 DAT).
Maps showing isolines of planting dates of Au s and Aman
rice, irrigation requirements at stage-2, total irrigation , ratio
of runoff. at stage-1 to irrigation requirements at stage-2 have
also been prepared. |
