| Abstract | A study on rainfed agriculture in the Mekong Delta of Vietnam
is conducted. A mathematical model for water balance analysis in
paddy fields at large scale level is used. This model is refined
from a model developed by AIT. The upper limit of water depth is
reset, the date for starting simulation is determined by using
rainfall probability, and some parameters are changed to make more
suitable with t he conditions of the Mekong Delta. A computer
program is also written for the refined model.
In simulation model, the output will be the main factors,
namely number of stress days (with the consecutive stress period is
introduced) and drainage requirement. The other factors such as
effective rainfall, supplementary water requirement are also
provided, if needed.
The simulation work has been done for four units of rainfed
area in the Mekong Delta. The results obtained from simulation,
considering the aforementioned factors , indicate that two crops per
year are possible. Number of possible alternative cropping patterns
are also proposed. |
