| dc.description | Rice (Oryza sativa L.) is the main food crop of Bangladesh. It is the
staple food for her people and will continue to remain so in the future. It grows
in all crop growing seasons of the year and occupies about 77% (10.71 Mha) of
total uence area. At present, rice alone constitutes about 92% of the total food
grains pecibad annually in the otis It provides about 75% of the calorie
and 55% of the protein in the average daily diet of the people (Bhuiyan eft al.,
2002). It also ensures political stability for the country and provides a sense of
food security to the people. But the average yield of rice of Bangladesh is quite
lower compared to that of other leading rice producing countries of the world, -
such as Japan, China, Korean Republic and U.S.A where t/ha yield is 6.22,
6.06,7.00 and 6.35 tons, respectively (FAO, 1999). | en_US |
| dc.description.abstract | The study was conducted at the experimental farm of Hajee Mohammad
Danesh Science and Technology University, Dinajpur, with a view to study
on water balance of irrigated T. Aman rice. The water balance study was
conducted in the T. Aman season of 2004.The experiment comprised two
treatments viz. continuous standing water (1-7cm) and irrigation (5-7cm)
after 3 days of disappearing of standing water. The field experiments showed
that in T. Aman season 7% of the total supplied water (including rainfall) was
required for land preparation, 30% was used for evapoptranspiration (ET),
45% was lost as seepage and percolation and the rest 18% was lost as surface
runoff due to heavy rainfall and other unaccounted losses. Therefore, from
this study it can be concluded that on an average only 30% of the supplied
water in irrigated rice field is used as evapotranspiration and the rest 70% is
lost by different processes. The irrigation treatment, irrigation after 3 days of
disappearing of standing water is not applicable in T. Aman season due to
rainfall. Therefore, water saving techniques like shallow application of water,
if adopted properly may lead to efficient utilization of water through
minimizing excessive losses of seepage and percolation. | en_US |
