| dc.description | All over the world, the importance of agriculture, especially rice production, is
increasing. To cope with the rising population, rice production needs to increase
following vertical, instead of horizontal expansion. Rice (Oryza sativa L.) is one
of the most important crops in Bangladesh. It is the largest crop in terms of area
and production in Bangladesh. Although rice in Bangladesh is consuming large
acreage, Bangladesh is still far behind other rice producing countries. The average
yield is very low (2 t ha”) as compared to Egypt (8.4 t ha’) and USA (6.6 t ha”)
(Anonymous 2006, Khakwani et al. 2005). There are many reasons for this low
yield. The most important are use of seedlings of unsuitable age and use of
different water levels by farmers. The combined effect of these factors usually
produces high seedling mortality just after transplanting. | en_US |
| dc.description.abstract | A field experiment was conducted at the research farm of Crop Physiology and
Ecology Department, Hajee Mohammad Danesh Science and Technology
University (HSTU), Dinajpur during November 2010 to May 2011 to find out the
effect of age of seedlings and water management on tillering behavior, growth
dynamics, and yield and yield contributing characters of BRRIdhan 28. The
experiment was laid out in two factors randomized complete block design with
four replications taking two seedling age (15 and 30 days old) at transplanting and
two water management (continuous flooding and intermittent irrigation) as the
factors. 15 days old seedling provided greater ability of tiller production, dry
matter accumulation and to produce more leaf area of BRRIdhan than those of 30
days old seedling but the ability was influenced more with intermittent irrigation
than continuous flooding. Transplanting of younger seedling provided more
effective tillers hill’, filled grains panicle’, thousand grain weight and finally
grain yield than those of older one but the younger seedling interacted with
intermittent irrigation significantly to explore all of these parameters. 15 days old
seedling of BRRIdhan 28 took shorter time to be matured than 30 days old
seedling in both continuous flooded and intermittent irrigated condition. Again the
crop matured 2 days earlier in intermittent irrigated plot than continuous flooded
plot for both 15 and 30 days old seedling. Finally it may be concluded that
transplanting of younger seedling in combination with intermittent irrigation
performed the best in tillering production, growth dynamics, and yield and yield
contributing characters of BRRIdhan 28. | en_US |
