Abstract/ Executive Summary:

Grasspea is probably the most drought tolerant legume crop and it is also resistant to moderate salinity. An experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during rabi season of 2018-2019 to evaluate the performance of different genotypes/lines under saline soil. There were 3 genotypes of grasspea (SEL-1348 , BKX-002-4 and Serajgonj local (E₃) where BARI khesari-3 was used as check variety. Highest seed yield (1.30 t/ha) was recorded in Serajganj local which was significantly higher than the rest of the varieties/lines. Similar trend was observed in case of straw yield (4.31 t/ha). BKX-0002-4 was the shortest durational one among the studied genotypes. The lowest level (5.25 dS/m) of soil salinity was recorded at the sowing time in BARI Khesari-3 and the highest level of salinity (10.35 dS/m) was recorded in the harvesting stage at SEL-1348.

Keywords: Genotypes, Ggrasspea, Salinity, Growth

Location: Agricultural Research Station (ARS), BARI, Benarpota, Satkhira

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Soil salinity, Grasspea

Objectives:

To evaluate genotypes of grasspea for their salt tolerance in early stage of their growth.

Methodology:

Experimental site: The experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during the rabi season of 2018-2019 to evaluate the performance of different genotypes/lines under saline soil. The soil belonged to the AEZ-11 and AEZ-13. The land topography was medium high. The soil of the experimental field is clay loam in texture. Design & data collection: There were 3 genotypes of grasspea (SEL-1348 (E₁), BKX-002-4 (E₂) and Serajgonj local (E₃) where BARI khesari-3 was used as check variety. The unit plot size was 3m X 3m. Seeds were sown in the field in 28 November 2018. The experiment was laid out in RCB design with 3 replications. At every 15 days interval soil and water salinity (dS/m) were measured by EC meter (HANNA: HI 9835). Data on yield and yield contributing characters were recorded and analyzed statistically using MSTAT-C program. Seed sowing & crop management: Recommended doses of 20-20-20 NPK in the form of urea, TSP, MoP and cowdung (10 t/ha) were applied. Germination was ensured through freshwater and saline water irrigation. Medium saline canal water was used for irrigation when needed. Weeding and other intercultural operations were done when necessary. The crop was harvested at the time of maturity.

Achievement/Findings:

Serajganj local can be a promising high yielding line for coastal areas of Bangladesh where BKX-0002-4 was short durational among all genotypes. Experiment should be conducted next year for final recommendation.
