Three Glutinous Rice Varieties under Low Land
Conditions in Khulna Region. South Asian J. Argic.,
2006, 1(2), 113-115.
A field experiment was carried out during aman
season, 2003 at experimental low land field of
Khulna University, Khulna to find out the suitable
genotypes(s) of glutinous rice (Oryza saliva L.) for
the south-west coastal region of Bangladesh. Three
glutionus rice varieties Pushbiruine, Kathalibiruine
and Pakbiruine were studied under this experiment
at Randomize Complete Block Design (RCBD).
Doses of urea, TSP and MP were applied at 88, 50
–1
and 35 kg ha . However, all of TSP and MP along
with one fourth of urea were applied as basal at
final land preparation and the rest three fourth of
urea were top dressed at 10, 25 and 45 days after
transplanting of 30 days old seedling. During the
growing period, plant height was recorded at 28,
50 and 73 days after transplanting and at
harvesting time as well. On the contrary, data on
yield and yield components were collected at
maturity. Kathalibiruine resulted in longer panicle,
higher thousand-grain weight and higher grain
yields. Thus based on the above selected
parameters, it was inferred that Kathalibiruine was
the most promising variety to be cultivated in
southwest coastal region of Bangladesh.

The inoculation effect of six indigenous strains of
Azospirillum spp. on growth and yield of rice
126
cxperiments. The Azospirillum inoculation
improved both growth and yield of rice. The plant
height was significantly increased by 8.70-50.80%
in all stages of growth. Both fresh and dry weights
of plants were also improved by 50.0-102.55% and
64.78-126.31% respectively. The panicle weight,
seed numbers per panicle and seed weight also
significantly increased by 12.5-75.0%, 10.69-
46.99% and 60.0-88.0% respectively. N 2-content
and protein content of rice grains were higher
compared to that of the control.

on the Yield of Soybean Crop Under Different Climatic
Conditions. Bang. J. Sci. Ind. Res.; 2006, 41(1 & 2) 73-

Soybean (Glycine mdx L., Variety PB-l) is an
important oilseed crop though not extensively
cultivated in Bangladesh. Five different plant
extracts i.e., Bara Bishkatali leaf extract, sesame
seed oil, castor seed oil, a mixture of sesame oil
and 'neem seed oil and tobacco leaf extract were
sprayed prior to pest infestation. The major insect
pests encountered were the leaf roller (Sylepta
derogata), pentatomid bug (Nezara viridula and.
Piezodorus hybneri), noctuid semilooper
(Trichoplusia ni) and blue butterfly (Euchrysops
cnejas). Among the applied treatments, tobacco
leaf extract showed the best result followed by
Bara Bishkatali leaf extract, sesame seed oil and a
mixture of sesame oil and neem seed oil and castor
oil. Some unidentified beneficial eurytomid,
braconid, ichneumonid and encyrtid insect
parasites and coc-cinellid predatois played an
important role in suppressing the pest population
during the study period. The maximum yield was
