Abstract/ Executive Summary:

The experiment was carried out to determine the performance of four blackgram genotypes for yield and yield contributing characters at Ishurdi, Pabna; Barind, Rajshahi; Jessore, Madaripur, Jamalpur and Gazipur. The genotypes were BG-7, BG-4, BG-2 and BARI Mash-3 as a check. In case of days to flowering and days to maturity over six locations, no genotype performed earlier than Check variety BARI Mash-3, but all genotypes flowered early at Jamalpur location and mature early at Joshore location. Among all genotypes, BG-4 was bold seeded. The highest mean seed yield was recorded in BARI Mash-3 (1474kg/ha) followed by BG-4 (1355 kg/ha) and BG-2 (1338 kg/ha). Therefore, two genotypes BG-4 and BG-2 were selected for further evaluation in the Participatory Variety Selection trial in the next season at different locations of Bangladesh.

Location: Pulses Research Centre, Ishurdi, Pabna, Pulses Research Sub Station, Gazipur;OFRD, Barind, Rajshahi; Regional Agricultural Research Station at Jessore, Jamalpur and Barisal, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Black gram

Objectives:

To evaluate them over locations to assess their performance. Generally, entries are evaluated over regions under regional yield trial.

Methodology:

The experiment was carried out at Pulses Research Centre, Ishurdi, Pabna, Pulses Research Sub Station, Gazipur;OFRD, Barind, Rajshahi; Regional Agricultural Research Station at Jessore, Jamalpur and Barisal during kharif-II, 2018 following RCB design with 3 replications. Seeds were sown in the field on 12-22 August 2018. Each entry was sown in-unit plot of 8 rows × 4 m long with a spacing of 40×10 cm. Seeds were sown in the rows carefully by hands at 3 cm depth and then covered by soils. Post sowing irrigation was given to ensure seed germination. Mulching was done and soil crusts were broken. Each of the entries was investigated from seedling to harvest and compared with a check. Grain yield was calculated from the whole plot. At maturity, the best individual genotypes were selected on the basis of earliness and higher yield. Yield data was recorded from the whole plot and converted into kg/ha. The statistical analysis was done using R computer software. Yield and yield contributing characters were presented

Achievement/Findings:

From this evaluation, it may be concluded that two genotypes BG-4 and BG-2 were suitable for high yielding at different locations. It can be selected for testing in the farmer’s field for final evaluation before releasing as varieties.
