| dc.description | Rice (Oryza sativa, L.) is the principle food of Bangladesh and it is the
world’s second important food grain. It belongs to the family Gramineae.
Rice is grown worldwide on 150million hectares (ha) with the total
production of about 563 million tons of unmilled rough rice (FAO, 1999).

Nearly half of the total population of the world use rice as their staple
food and it 18, main Source of calories for about 40% of the world
population (Hoffman, 1991). Bangladesh is not only a rice growing
country but also a rice-eating people. It is the forth-largest country in the
world with respect to rice area and production (IRRI, 2000). Rice is
cultivated in more than 10% of the earth arable land of the world (FAO,
1999). | en_US |
| dc.description.abstract | The study was conducted in the Experimental Farm of Hajee Mohammad
Danesh Science and Technology University, Dinajpur with a view to
determine Crop Coefficient (Kc) value from irrigated T. Aman rice
during the T. Aman season of 2004. The results showed that on an
average, the seasonal evapotranspiration (ET) rate was 4.28 mmi/day. The
total ET demand in T. Aman season was calculated to be 437 mm and the
peak demand was 4.41 mm during the month of August. The effective
rainfall during the growing period was 526 mm which is more than the total
ET demand of 437 mm. The seasonal crop evapotranspiration (ETc) using
the lysimetric method, reference evapotranspiration (ETO) by computer
program ‘CROPWAT* and Kc values were determined. The determinated
values of crop coefficients for T. Aman rice at the four stages (initial, crop
development, reproductive and maturity) were 1.06, 1.03, 1.07 and 1.07.
The mean Ke value for T. Aman rice for growing season was found to be
1.06 and also found the highest crop coefficient value (1.07) at reproductive
and maturity stage and lowest value (1.03) at the development stage. | en_US |
