| dc.description | Globally, rice is the second most important crop to wheat in terms of area
but as food rice is important since it provides more calorie than any other cereals.
About 40% of the world’s population consume rice as a major source of calorie
pro, 1999). Among the major rice growing countries of the world, Bangladesh
ranks third in respect of growing area and fourth in production (Huke and Huke,
1990)! Here rice is cultivated in 10.26 million hectares having the average yield
1.79 tha’ with the production of 19.9 million metric tons (BBS, 1999). In the year
2002, the food grain requirement of the country will be 25 million metric tons.
Rice, the staple food ofthe country is cultivated in the 76% of the arable land
B S, 1999). It plays a vital role to the Bangladesh economy as it contributes
‘about 50% of the total agricultural value added and engages over 65% of the total
agricultural labour force. Besides, rice production continues to be one of the
important sources of livelihood accounting for 76% of people’s average calorie
intake and 66% of protein intake (BBS, 1996). | en_US |
| dc.description.abstract | An experiment was carried out to investigate the effect of spacing and
nitrogen level on yield and quality of some varieties of aromatic rice at the
Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh
from July to December 2000. (The experiment included three varieties namely,
Kalizira, Badshabhog and Tulshimala, four different spacing namely, 8 cmx25 cm,
12 cm x 25 cm, 16 cm x 25 cm and 20 cm x 25 cm and three nitrogen level viz.,
40, 60 and 80 kg ha’.\The experiment was laid out in a split-split plot design with
three replications. Except only few parameters, (the yield, yield contributing
characters, qualitative characters and soil properties were significantly influenced
by spacing and nitrogen level in all varieties of aromatic rice. Yield increased with
increasing spacing and nitrogen level up to certain limit of all varieties along with
the improvement of yield contributing characters) Badshabhog was found
significantly superior to Kalizira and Tulshimala with respect to number of grains
panicle’, 1000-grain weight, grain yield, and harvest index. Among four spacings,
the highest grain yield (2.84 t ha’') was obtained from spacing (16 cm x 25 cm).
Among three nitrogen levels, significantly highest grain yield (2.85 t ha”) was
obtained from 60kg N ha”. The effect of interaction of spacing and nitrogen,
variety and spacing and variety, spacing and nitrogen level was not significant. The
effect of spacing and nitrogen level on different qualitative characters viz., nitrogen
content (%), nitrogen uptake (kg ha”), protein (%), germination (%), vigour index
were significant in all varieties of aromatic rice/ (All the qualitative characters
(except aroma and cooking time) were found to increase significantly with the
increasing from 8 cm x 25 cm spacing to 16 cm x 25 cm and 40 to 80 kg N ha",
respectively. Most of the interaction effect was not significant. Post harvest soil
analysis that the organic matter depleted and mining occurred in the case of
exchangeable K and available P. The level of total N did not decrease due to
nitrogen application. | en_US |
