Abstract:
The study was carried out at the Agronomy Net-house Sher-e-Bangla
Agricultural University, (SAU), Dhaka-1207, during the period November
2016 to April 2017 to study the influence of salinity levels on yield attributes,
yield and seed quality of three selected chilli varieties. For this purpose three
varieties of chilli viz. Local, BARI Morich 1, BARI Morich 2 and 4 levels of
salinity viz. 0 dS/m, 3 dS/m, 6 dS/m and 9 dS/m NaCl concentration were used.
The experiment was conducted by following Completely Randomized Design
(CRD) with three replications. Results showed that in terms variety BARI
Morich 1 is the best variety than other two. BARI Morich 1 (V
2)
showed the
best result in plant height (27.16 cm), leaf number (28.75), pod length (6.63 cm),
dry weight of plant (83.62 g), number of marketable fruit per plant (94 pieces
on an average), weight of per green fruit (4.08 g), weight of per dry fruit (0.21
g), harvest index (18.46%), germination (54.50%), root length (4.44 cm), shoot
length (5.38 cm), seedling length (10.32 cm) and dry weight of seedlings (0.30
g). In case of salt concentration application the best result was recorded in
control (0 dS/m salt concentration). Results showed that in terms of salt
concentration application of 0 dS/m salt concentration showed the highest
plant height (29.11 cm), leaf number (29.88), pod length (6.44 cm), dry weight
of plant (83.99 g), number of marketable fruit per plant (93.33 piece on an
average), weight of per green fruit (4.54 g), weight of per dry fruit (0.24 g),
harvest index (15.69%), seed germination (50.44%), root length (4.75cm),
shoot length (5.69 cm), seedling length (10.40 cm) and dry weight of seedlings
(0.29 g). The lowest result was found in case of S
3
(9 dS/m salt concentration).
Considering interaction effect of variety and salinity V
2
S
0
was recorded for the
best result in plant height (30.66 cm), leaf number (32.33), pod length (6.90
cm), number of marketable fruit per plant (101.33 piece on an average), dry
weight of plant (87.35 g), weight of per green fruit (4.86 g), weight of per dry
fruit (0.26g), harvest index (21.34%), seed germination (59%), root length
(5.02 cm), shoot length (5.90 cm), seedling length (10.94 cm) and dry weight
of seedlings (0.32 g). From the above result concludes that no chilli variety can
perform better in saline condition.
