EVALUATION OF EXOTIC POTATO GERMPLASM ON YIELD AND YIELD CONTRIBUTING CHARACTERS
HAQUE, MD. EAKRAMUL
A field experiment was conducted with 12 exotic potato germplasm viz. Atlantic, Atlas, Aziba, Billini,
Croste, Daifla, Daise, Delaware, Quincy, Sagita, Sassy, Spunta with Diamant as check at Breeder Seed
Production Center, Debigonj, Panchagorh, during December 21, 2006 to March 28, 2007 to determine their
suitability as a variety in Bangladesh. All the varieties gave more than 90% emergence at 20-35 DAP (Days
after Planting). Tallest (87.8 cm) plant height was recorded in Quincy and the shortest (57.0 cm) was from
Atlas and the minimum (2.0) was obtained from Daifla. Maximum (7.2) stem number per hill was counted
in Diamant followed by Delaware. Although there was significant variation among the varieties on foliage
coverage but all showed more than 90% foliage coverage at 60 DAP and 100% foliage coverage was shown
by Daifla, Aziba and Sagita. Significant variation in stem (plant) diameter among the varieties were evident.
Maximum (5.9 cm) plant diameter was recorded from Atlas and the minimum (2 .6 cm) was from Diamant.
Number of tuber per plant ranged from 6.5 to 14.1 with the minimum and the maximum by Croste and
Delaware, respectively. Significantly the highest yield (44.5 t/ha) was found in Aziba and the lowest (32.29
t/ha) was obtained from Sassy. Irrespective of varieties, all produced maximum percent of seed tuber
(grade) both by number and by weight. All the varieties showed late blight infection even after receiving
two times fungicidal spray. All the varieties were free from PLRV (Potato Leaf Roll Virus) infection except
Atlantic, Atlas, Spunta and Diamant. Regarding PVY (Potato Virus Y), varieties showed trace infection
which ranged from 0.33-2.33%. Five varieties (Croste, Daifla, Quincy, Sassy and Diamant) were free from
PVY. Varieties contained more than i0% dry matter were Atlas, Croste, Daise, Sagita, Sassy and Diamant.

PERFORMANCE OF OKRA GERMPLASM WITH SPECIAL REFERENCE TO YELLOW VEIN MOSAIC VIRUS
RASUL, MD. HUMAYUN KABIR-E
The experiment Was undertaken to study the performance of okra germplasm with
special reference to yellow vein mosaic virus among 36 accessions at the
1-l0rticult1lre Farm Division, lIorticulwre Research Centre, Bangladesh
Agricultural Research Institute, .Ioyclebpur, Gazipur, during the period from April
2007 to August 2007. There was a wide range of clilThrent parameters. The
maximum (169.37 em) plant height was observed from accession number 14 and
the maximiflhl spread of plant was found from accession number 138 (14.62) was
recorded from accession number 219 and 114 respectively. At 80 DAS the plant
performed the maximum (94.2) number of leaves was obtained from accession
number 138. The maximum leaf breath (35.1 cm) was recorded from accession
number 148. The minimunl (36.39) and the maximum (68.08) (lay's was required
for days to first flowering were from accession number 144 and 114 respectively.
The minimum (14.27%) plant was infested by virus at 75 DAS in accession
number 139 compare to other accessions number. So, accession number 139 was
identified as agronomicallY acceptable resistant line against okra yellow vein
mosaic virus.

EFFECT OF IAA AND GA3 ON THE GROWTH, CURD FORMA TIO AND YIELD OF CAULIFLOWER
AKHTER, MOSAMMAT NAZIA
An experiment was carried out at the Horticultural farm, Sher-e-Bangla Agricultural
University, Sher-e-Bangla agar, Dhaka-1207 during October 2006 through January
2007 with two growth regulators, Gibberellic Acid (GA3) and lndole Acetic Acid (IAA)
applied at two different stages namely vegetative stage and curd formation stage to
observe the growth, curd size and yield contributing characters of the modem HYV
cauliflower cultivar, 'Shirajuki'. The experiment was laid out in a Randomized Complete
Block Design (RCBD). The field experiment had three replications. There were three
concentrations of IAA (0, 5, 10 ppm) and GA3 (0, 80, 100 ppm). Application of IAA 10
ppm resulted the minimum (47.76) days from transplanting to curd initiation and the
maximum (34.40 cm) plant height was at harvest while the minimum (28.86 cm) was
recorded from control treatment. The maximum number of leaves per plant (25.04).
length of the largest leaf (50. 77 cm). breadth of the largest leaf ( 18.20 cm) at harvest,
curd diameter at harvest (23.38 cm) were recorded from IAA 5 ppm (11) whereas, the
minimum was recorded from control treatment. Application of GA3 100 ppm (G2)
resulted the highest pure curd height ( 14.59 cm), curd weight with leaves ( 1.90 kg) at
harvest, marketable curd weight (1.33 kg /plant) and curd yield (53.33 t/ha) while the
lowest was recorded from control treatment. The maximum benefit cost ratio (BCR)
(2.93) was recorded from the treatment combination of I2G2 while the minimum
(1.18) was recorded from control treatment. So, IAA 10 ppm and GA3 l 00 ppm
indicating the economic viability of using growth regulator in curd growth and yield
of cauliflower.

EFFECT OF GROWTH REGULATORS AND FERTILIZER MANAGEMENT PRACTICES ON THE FLOWERING, FRUIT SET AND YIELD OF BITTER GOURD (Momordica charantia L.)
MOMIN, MOHAMMAD ABDUL
A field experiment was conducted to examine the effect of growth regulators (IAA and
Ripen-15) and fertilizer management practices on the flowering, fruit set and yield of
bitter gourd (Hybrid Corolla- Penta Green) during April to July 2007 at the Horticulture
farm of Sher-e-Bangla Agricultural University, Dhaka. The experiment was considered of
two factors. Factor A: Different plant growth regulators viz. control (H
),
Ripen-15 (H
2
) and IAA+Ripen-15 (H
) and Factor B: Fertilizer management practices
viz. control (F
0
), organic manure (F

3
) and inorganic manure (F
). It was laid out in the
two factors Randomized Complete Block Design (RCBD) with three replications. The
data obtained for different characters were statistically analyzed to find out the
significance of the PGR’s and fertilizer management practices. The tallest plant at 1st
flowering time (163.90 cm), the lowest ratio of male and female flower (3.08), the
maximum fruit weight (129.10 gm) were recorded from the application of IAA+Ripen-15
(H
3
2
) but the maximum number of fruit (18.26) and highest yield per hactare (21.89) was
found from application of Ripen-15 (H
) and the minimum was recorded in control
condition. The tallest plant at 1st flowering (160.72 cm), the lowest ratio of male and
female flower (3.06), the maximum number of branches (11.86), nodes (26.33), female
flowers (23.72), fruits (16.35), maximum fruit weight (119.92 gm) per plant and the
highest yield (19.11 t/ha) were recorded from the application of inorganic fertilizer (F
2
)
and the minimum was recorded in control condition. Interaction effect between plant
growth regulators and fertilizer management practices showed a statistically significant
variation incaseof most of the recorded characters. The combination of Ripen-15 and
inorganic fertilizer (H
2
F
) gave the highest gross return (Tk. 510,000) which is closely
followed by combination of Ripen-15 and organic fertilizer (H
2

F
). The lowest gross
return (Tk. 208,000) was obtained in the control condition where no plant growth

), IAA (H

regulator as well as no fertilizer was applied. The combination of Ripen-15 and inorganic
fertilizer (H

F
) gave highest benefit cost ratio (2.47) and the lowest benefit cost ratio
(0.61) was obtained in combination of control conditions (H

).
