| dc.description | Rice (oryza sativa L.) is the primary food for half of the people of the world.
In many regions it is eaten with every meal and provides many calories than
any other single food. Rice contributes more than 70% of total production
and 60-94% of daily calorie intake in China, India, Pakistan, Bangladesh
and Nepal (Prasad et al., 1999). Bangladesh is an agro-based country.
About 75% of her population depend on agriculture. Rice is extensively
grown throughout the year, such as Aus, Aman and Boro. Rice is one of the
major food crops of the world. Worldwide rice is cultivated in 150 million
hectares, which is more than 10% of the earth’s arable land. It is also the
staple food crop of nearly half of the total population of the world and is the
main source of calories of almost 40% of the world population (Hoffman,
1991). It is the most important crop in Asia as a whole comprises to about
92% of the world rice harvest (IRRI, 1995). | en_US |
| dc.description.abstract | A field experiment was conducted to study morphochemical, yield and yield
contributing characters of five boro rice cultivars viz. BINA dhan7, Hybrid
rice cv. SL-8H, Poshusail, Jirasail and Swarna at the field laboratory of the
department of Agricultural Chemistry, Hajee Mohammad Danesh Science
and Technology University, Dinajpur, during the period from February to
May, 2014. The experiment was laid out in one factor Randomized
Complete Block Design with three replications. Results revealed that the
morphological, physiological, yield and yield attributes were significantly
different among the studied cultivars. The hybrid cultivars was shorter in
plant height, having more tillering ability, higher leaf number which in turn
showed superior growth character and yield. The hybrid rice cv. SL-8H
produced higher number of grains panicle-1 which resulted higher grain
yield. Further, hybrid rice cv. SL-8H showed superiority in yield
contributing characters erect leaves and total dry mass over other local
cultivars and it also produced higher grain yield (8.42 t ha-1
). Among the
five rice cultivars, hybrid rice cv. SL-8H had the highest yielding ability.
The highest chlorophyll-a content was found in hybrid rice cv. SL-8H and
while the lowest chlorophyll-a content was observed in poshusail and
jirasail, which were statistically similar. BINA dhan7 contained the highest
calcium, magnesium and potassium content in flag leaves while hybrid rice
cv. SL-8H had the highest phosphorus content in flag leaves. | en_US |
