Özet
Malnutrition is one of the major problems in the
poor people of Bangladesh. There are some reports
that additional nitrogen (over than recommended
does) application to wheat plants result in more pro tein content in wheat grain. To justify these phenom ena, the experiment was conducted in consecutive
two years (2015-16 and 2016-17) at two locations
(Gazipur and Dinajpur) during rabi season (Novem ber to March each year). There were used six nitro gen (N) treatments, such as 0, 100, 125, T3; 150, 175
and 200 kg N ha-1
. In the study, wheat cultivated at
Dinajpur location exhibited more spikes m-2
, spike
length, spikelets spike-1
, grains spike-1
, 1000-grain
weight and higher grain yield in both years than
Gazipur location. Considering combined N levels
over the locations, the highest grain protein (14 %)
as well as grain yield (5.00 t ha-1
) was estimated
when 200 kg N ha-1 was applied. In economics point
of view, 200 kg N ha-1 application also gave the max imum (BCR, 1.21) followed by 175 kg N ha-1 (1.20)
and 150 kg N ha-1 1.20). Whereas, the maximum
MBCR was found in 100 kg N ha-1 (15.63). There fore, to minimize malnutrition severity among the
children as well as adult people in the developing
countries like Bangladesh, 175 or 200 kg N ha-1 may
be applied in wheat to increase percentage protein in
wheat grain.
