Abstract/ Executive Summary:

Ten stem amaranth germplasm viz. AS-Akb-001, AS-Akb-002, AS-Akb-003, AS-Akb-004, AS-Akb-005, AS-Akb-006, AS-Akb-007, AS-Akb-008, AS-Akb-009, and AS-Akb-010 were evaluated at RARS, Akbarpur during the summer season, 2018. The highest stem diameter both at base and middle was produced by the line AS-Akb- 005 that lead to the higher stem yield. The line AS-Akb- 005 required 49 days to first flowering that enhanced better stem production. The maximum seed yield of 6.75 t/ha was recorded in the line AS-Akb- 006 followed by the line AS-Akb- 005 (6.25t/ha). The stem weight and stem diameter had a maximum direct effect on yield and the line AS-Akb–005 performed the best whereas yield was minimum in the line AS-Akb-010.

Location: RARS, Akbarpur, Molvibazar, Sylhet, Bangladesh

Start Date: 00-00-2017

End Date: 00-05-2018

Program Area: Crop-Soil-Water Management

Commodity: Amaranth

Objectives:

The present study has been undertaken with the following objectives:

To develop high yielding variety of stem amaranth
To conserve stem amaranth germplasm for diversification of genetic resources

Methodology:

The experiment was conducted at RARS, Akbarpur during the summer season, 2018. Ten stem amaranth germplasm viz. AS-Akb-001, AS-Akb-002, AS-Akb-003, AS-Akb-004, AS-Akb-005, AS-Akb-006, AS-Akb-007, AS-Akb-008, AS-Akb-009 and AS-Akb-010 were evaluated. The germplasm AS-Akb-003, AS-Akb-006, AS-Akb-008 and AS-Akb-010 were collected from Moulovibazar Sadar. The germplasm AS-Akb-002, AS-Akb-007 were collected from Sylhet Sadar and the germplasm AS-Akb-001 and AS-Akb-009 were collected from Narashingdi. The experiment was laid out in a non-replicated design. The unit plot size was 6m × 1m. After final land preparation, the seeds were drilled by hand, mixed with some sand to allow uniform sowing in a row. As the amaranth seeds are small, so it was covered by a thin layer of loose fertile sandy loam soil. Distance between two rows was 30 cm. Manures and fertilizer were applied at the rate of cowdung 20 t/ha, urea 200kg/ha, TSP 100kg/ha, MOP 200 kg/h. The entire quantity of cowdung, MOP and TSP were applied during final land preparation. Urea was top-dressed in three equal splits. The first, second, third top dressing was done at 15days, 21 days, and 28 days after sowing respectively. Irrigation and other intercultural operations were done as and when necessary. Data were recorded on plant height, a number of leaves and branches, stem diameter, stem weight, fresh weight of the plant, days to first flowering, and seed yield(t/ha).

Achievement/Findings:

Results of an experiment for different characters are presented in table 1. The maximum stem weight (390.25g/plant) was contributed by the line AS-Akb- 005 followed (355.50g/plant) by the line AS-Akb- 006. The minimum stem weight (225.50 g/plant) was contributed by the line AS-Akb- 010. The highest fresh weight (594.75 g/plant) was recorded in the line AS-Akb- 005 and the lowest fresh weight (275.25 g/plant) was recorded in the line AS-Akb- 010. The highest stem diameter both at base and middle was produced by the line AS-Akb- 005 that lead to the higher stem yield. The line AS-Akb- 005 required 49 days to first flowering that enhanced better stem production. The maximum seed yield of 6.75 t/ha was recorded in the line AS-Akb- 006 followed by the line AS-Akb- 005 (6.25t/ha). The minimum seed yield of 4.53 t/ha was recorded in the genotype AS-Akb- 010. The results of the experiment revealed that yield was mainly contributed by plant height, stem weight, stem diameter, number of leaves, etc. The stem weight and stem diameter have a maximum direct effect on yield and the line AS- Akb – 005 performed the best whereas yield was minimum in the line AS- Akb- 010. The line AS-Akb-005 performed the best among the lines and the experiment will be continued for a conclusion.
