| 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).
There are many reasons for this low yield. The most important of them is the
indiscriminate and improper application of nutrients with unfavourable condition.
Because it may not provide ‘ssc nutrients supply because of its poor
absorption and translocation in plant system. Many factors determine the fertilizer
efficiency for rice crop during cultivation such as soil, cultivar, season,
environment, planting time, water management, weed control, cropping pattern,
source, form, rate, time of application and method of application (De Datta,
1978). | en_US |
| dc.description.abstract | An experiment was conducted to find out the effect of foliar fertilization (Magic
growth) on performance of BRRIdhan 28 and to calculate how much urea can be
saved by foliar fertilization of Magic growth without any yield reduction at the
research field and laboratory of Crop Physiology and Ecology department, Hajee
Mohammad Danesh Science and Technology University, Dinajpur during the
period of November 2012 to June 2013. The experiment was conducted in a split
plot design with three replications. Two levels of foliar fertilization (no foliar
fertilization and foliar fertilization with magic growth) were placed in the main
plots as main plot treatments whereas four nitrogen fertilizer levels (0, 50, 75 and
100% of the recommended nitrogen fertilizer) were placed randomly in the sub
plots as sub plot treatments. Foliar fertilization with magic growth showed higher
plant height, tillers hill’, SPAD value of the youngest fully expanded leaf and
above ground biomass at 40, 55, and 70 DAT (days after transplanting) compared
to no foliar fertilization treatment. All the parameters were also increased with the
increment of nitrogen level. Foliar fertilization and increasing nitrogen fertilizer
levels significantly influenced effective tillers hill', spikelets panicle’, grains
pnicle”', thousand grains weight, grain yield and straw yield of BRRIdhan 28. In
general, foliar fertilization (F,) treatment provided greater grain yield compared to
no foliar fertilization treatment (Fo) in all nitrogen levels. On the other hand, with
the increment of nitrogen level the grain yield was increased up to Njo9 in no foliar
fertilization treatment (Fo) but in foliar fertilization treatment (F)), grain yield was
increased with the increment of nitrogen level up to N75 and there after decreased
in Njoo, Foliar fertilization with magic growth along with 50% of the
recommended nitrogen fertilizer saved 50% of the recommended nitrogen
fertilizer without any yield reduction. Foliar fertilization with magic growth along
with 75% of the recommended nitrogen fertilizer increased 16.9% grain yield with
a saving of 25% of the recommended nitrogen fertilizer whereas foliar
fertilization along with 100% recommended nitrogen fertilizer increased 9.33%
grain yield compared to recommended practice alone. | en_US |
