Abstract:
A pot experiment was held in the net house of the Department of
Agricultural Chemistry, Sher-e-Bangla Agricultural University, Sher-eBangla
Nagar, Dhaka-1207, during November 2016 to March 2017, to
study the effect of salinity on growth, yield and nutrient contents in
different wheat (Triticum aestivum L.) cultivars. Three cultivar viz.,
BARI gom-24, BARI gom-25 and BARI gom-26 and five salinity
treatments viz., S
0
(control), S
v
1
(3 dSm
-1
), S
2
(6 dSm
-1
), S
3
(9 dSm
) and
S
4
(12 dSm
-1
) were associated in this experiment. The experiment was
laid out in Randomized Complete Block Design (RCBD) with three
replications. Significant variation was recorded among three cultivars on
growth, yield and nutrient contents. Germination percentage, plant
heights, tiller number, effective tiller, spike length, total grain, 1000 grain
weight, grain yield per pot, straw weight, root weight and chemical
compositions (Nitrogen, Phosphorus, and Potassium) were found to be
decreased gradually with increasing salinity level, and also significant
variations were observed among cultivars. Number of ineffective tiller,
unfilled grain and chemical compositions (Sodium and Calcium) were
noticed to be increased gradually with the gradual increase in salinity
levels as compared to the control. All the three cultivars could be
survived and produced grain yield up to S
2
(6 dSm
-1
-1
) treatment. But in S
(9 dSm
-1
) treatment, BARI gom-24 and BARI gom-26 produced
significantly less grain compared to BARI gom-25. At S
)
treatment, all the three cultivars, were produced less grain yield and were
not suitable for cost-effective production in Bangladesh aspects. From
this execution, it can be stated that BARI gom-25 showed the best
performance and more tolerant in respect of all parameters than those of
BARI gom-24 and BARI gom-26.
