| dc.description | Bangladesh is one of the densely populated countries of the world having a
population of 15.25 million people (BBS, 2011). Most of the inhabitants depend
on agriculture but the existing land use systems with separate allocation to
agriculture and forest are insufficient to meet the demands of the 21st century.
Again, the northern part (Rajshahi, Dinajpur, Rangpur, Thakurgaon, Panchagar
and Bogra district) of Bangladesh is experiencing frequent droughts. A typical
dry climate with comparatively high temperature prevails in the northern part.
Moreover, a considerable reduction in land holdings during the last two decades
is evident and the trend is expected to continue in the time to come; the reason
being exponential growth in population. | en_US |
| dc.description.abstract | A field experiment was carried out at the Agroforestry and Environment research farm,
Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur,
during November 2013 to February 2014 to screening the performance of 4 (four)
potato varieties under different shade levels. The experiment included four modern
potato varieties viz; V\= Cardinal, V2 = Granulla, V3 = Xtirix and V4 = Raza and
different shade levels viz. S; = 100% light = 800 Lux, S2 = 75% light = 600 Lux and S3
= 50% light = 400 Lux. The experiment was laid out in RCBD with 3 (three)
replications. Potato tubers were planted on 15" November 2013 and harvested on 22™4
February 2014. The result revealed that the potato varieties played an important role in
growth as well as yield performance. At 30 DAP the tallest plant (46.33 cm) was
recorded from the variety Raza (V4) whereas the shortest plant (38.32 cm) was
observed from Granulla (V2).The maximum number of tuber hill” (7.75) was recorded
in Raza (V4) and the minimum was found (6.13) in Xtirix (V3). The potato tuber yield
was measured in tha’'. Significantly the highest tuber yield (27.25 tha’') was recorded
in Raza (V4) and the lowest tuber yield (23.53 tha’) was recorded in Granulla (V2). On
the other hand, different shade levels also affected significantly the growth and yield of
potato regarding different growth and yield contributing characters. At 30 DAP the
tallest plant (47.55 cm) was recorded in S3 treatment followed by in S2 i.e.75% light
and the shortest plant was observed (40.67 cm) in S; treatment i.e: 100% light
condition. The maximum number of tuber hill” (7.54) was recorded in (S;) treatment
and the minimum number of tuber hill"' (5.85) was found in (S3). The maximum weight
of tuber per hill (355.0 g) was observed in (S;) and the minimum (325.12g) was
recorded in (S3) treatment. The yield was found highest 30.87 t/ha in (Sj) and the
lowest yield 23.11 t/ha was found in (S3). Significantly the highest tuber yield (45.18
t/ha) was recorded in (S;V4) treatment combination whereas the lowest tuber yield
(31.66 t/ha) was recorded in (S3V2). It may be concluded that potato variety Raza has
been grown successfully as different light condition. In artificial shade created with
nylon net light conditions, potato variety Cardinal (at 75% light) and Xxttrix (at 50%
light) also gave the moderate yield. | en_US |
