Abstract/ Executive Summary:

The experiment was conducted at two different locations of coastal areas Potuakhali and Satkhira (Khulna) during rabi season to find out the performance of salt tolerant barley lines namely Barley Hull Less-15, Barley Hull Less-18 and Barley Hull Less-19 screened under laboratory. The crop was sown on 15^th December 2008 in Satkhira, 20 December 2008 in Potuakhali. Seeds were sown continuously and line to line spacing was 30 cm. Fertilizers at the rate of 100-60-40 kg/ha of NPK were applied as basal. The salinity level during the crop growing period was ranged from 2.01 dS^-m to 7.43 dS^-m at Banerpota, Satkhira and 2.93 dS^-m to 9.51 dS^-m at Kuakata, Potuakhali. Barley line BHL-15 performed better at Potuakhali and also at Satkhira. The line BHL-15 could be selected for cultivation in the coastal saline area of Bangladesh. Results revealed that salt tolerance made in laboratory condition showed consistent under field condition in the coastal area. BHL-15 showed better adaptability in the coastal saline area and would be suitable for cultivation.

Keywords: Performance, Salt tolerant barley, Coastal region

Location: Khulna and Kuakata, Potuakhali

Start Date: 00-00-2008

End Date: 00-00-2009

Program Area: Variety and Species

Commodity: Barley

Objectives:

To select salt tolerant barley varieties for the coastal areas.

Methodology:

The experiment was conducted at Satkhira, Khulna and Kuakata, Potuakhali during rabi season of 2008-09. Three varieties/lines namely BHL-15, BHL-18 and BHL-19 were used in this experiment. The crop was sown on 15th December’08 in Satkhira, 20th December in Potuakhali. Seeds were sown continuously and line to line spacing was 30 cm. Fertilizer was applied at the rate of 100-60-40 kg/ha of NPK in the form of urea, TSP and MP and were applied as basal. Data on yield and yield attributes were collected and analyzed statistically.

Budget: 30,000/-

Total Budget (Tk.) : 30,000/-

Achievement/Findings:

It may be concluded that salt tolerance made in laboratory condition showed consistent under field condition in the coastal area. BHL-15 showed better adaptability in the coastal saline area and would be suitable for cultivation. Pilot production programme should be taken in the next season for large scale demonstration.
