GROWTH AND YIELD OF T. AMAN RICE VARIETIES AS AFFECTED BY SEEDLING NUMBER HILL 1 AND UREA SUPERGRANULES
MASUM, SHEIKH MUHAMMAD
A field experiment was conducted at the experimental field of Sher-e-iIangla agricultural
university during July to December 2007 to find out the effect of four levels of seedling
hill4 vii;
I. 13 and 4 and two forms of nitrogen fertilizer-prilled urea (PU) and urea
supergranules (USC) on growth, yield and yield components of modem (BRRI Dhan 44)
and traditional (Nizershail) transplant oman
rice. The experiment was laid out in a split-
split-plot design with three replications. Urea was top dressed 58 kg N haS ' in three
equal splits at 10, 30 and 50 DAT. The USC (1.8 g) was placed at 5-10cm soil depth
at 10 DAT in the center of four hills in alternate rows
1 granule in one spot to
supply 58 kg N haS
'. Results showed that rice varieties differed significantly in all
growth characters and BRRI Dhan 44 produced higher grain yield (4.85 t ha'). Two
seedlings hill' gave the highest grain yield (3.96 t hi') while four seedlings hill' had
the highest numbers of total tiller hill', leaf area index and total dry matter. USC
performed well in growth and gave higher grain yield (12.2%) over PU. Interaction
results showed that significantly higher grain yields were given by transplanting one
seedling of 13RRl Dhan 44 (5.38 t hi'), application of USC in I3RRI Dhan 44 (5.08 t
hi') and transplanting one seedling hilr' with application USC (4.18 t had) and
finally placement of USC by transplanting one seedling hill' of BRRI Dhan 44 (5.77
hi'). The higher grain yield was attributed mainly to the number of effective tillers
bill', filled grains panicle' and 1000-grain weight.

An experiment Was conducted at the experiment field of the Department of

ciThet of nitrogen and irrigation managements on the yield attributes and yields
of mungbean

as a pulse crop showed a lag phase in early growth stage (up to 40 DAS) while
increase of growth parameters like number of leaves, leaf dry weight and steam
dry weight per plant very slow. Thus, initiation of flowers (35 DAS) caused
low dry matter production. Application of 30 kg N ha'' as basal with one
irrigation at first flowering stage (35 DAS) improved the growth parameters
significantly. This greater dry matter eventually supported the plant to produce
more number of branches and pods per plant. which resulted with maximum
seed yield per plant (5.53 g) or per hectare (1.65 ton). A Iiinctional positive
relationship was observed among number of branches per plant. pods per plant.

EFFECT OF MANURING AND SPLIT APPLICATION OF NITROGEN ON GRAIN YIELD AND QUALITY OF MAIZE
SHOUKAT, KHONDAKER YEASEN MOHAMMAD
An experiment was conducted at the agronomy field laboratory of Shcr-e-Bangla
Agricultural University, Sher-e-Bangia Nagor, Dhaka. during the period from March to
June 2006 to study the elThct of manuring and split application of nitrogen on grain yield
and quality of maize cv. F3arnali. There were four nianunal doses, namely. M
1 -
Inorganic Fertilizer (IF) only. M
2
- IF + cow-dung 5 t ha NI
)
- IF + cow-dung lOt ha'
and M4 - IF + cow-dung 15 t ha and two split applications of nitrogen. viz. SP
1 -2 splits
and SP:-3 splits. Manuring was placed in main plot and split application of nitrogen in
subplot each measuring Sm X 3m In a split plot design used with three replications. Four
nutrients were applied which were N, P
205
, 1(20 and Sat the rate of 115 -72 - 60 - 22.32
kg ha1
and three nutrients were supplied in the form of Urea, TSP, MP and Gypsum
respectively In SP
1
basal dose of urea was applied at final land preparation, and
split
at 25 and
split at 45 days of sowing. In SP
2
basal dose urea was applied at final land
preparation, and 3 splits respectively at 25. 45 and 65 days of sowing. Inorganic
fertilizers ± cow-dung 15 t ha
1
(M4
treatment) gave the best response for all the
parameters, whereas inorganic fertilizer (IF) only (M
1
treatment) gave the poorest
response. Grain and stalk yields ranged respectively from 5.43 to 9.02 t ha
4
and from
6.76 to 12.16 t ha" due to different manuring treatments. The highest grain yield was
obtained from M4
treatment, identically followed by M.; treatment, Grain protein content
10.6 was from M1
treatment and 13.16 from M., treatment, the latter being identically
followed by M, and M2
treatments: Grain N and protein contents were nearly 2 times
higher than those in stalk. Three split applications of N gave higher grain yield and
tended to increase nutrient content of grain and stalk over 2 split applications of nitrogen.
Results of the present study showed that application of cow-dung at the rate of 10 and IS
ha' together with recommended dose of inorganic fertilizers improved grain yield and
quality over inorganic fertilizers alone and 3 split applications of nitrogen increased grain
yield and tended to improve grain quality of maize over 2 split applications of nitrogen.
