Abstract/ Executive Summary:

Nine stem amaranth germplasm with one check variety were evaluated at the research field of Regional Horticulture Research Station of Bangladesh Agricultural Research Institute, Shibpur, Narsingdi during October 2017 to January 2018 for their yield, quality and virus resistance. The germplasm AT Nar-008 showed maximum plant height (177.72 cm) and stem length (169.77 cm). Minimum plant height (53.10 cm) and stem length 46.23 cm) were recorded from germplasm AT Nar-002. No. of leaves/plant was obtained highest (34.41) from AT Nar-004 and lowest (11.27) from AT Nar-006. Single plant weight was found highest (385.61 g) from AT Nar-005 and lowest (154.67 g) from AT Nar-002. Both yield/plot (15.75 kg) and yield (52.50 t/ha) were recorded highest from the germplasm AT Nar-004. On the other hand, the lowest yield/plot (5.14 kg) and yield (17.33 t/ha) recorded from the germplasm AT Nar-002. Days to harvest found minimum (43-46 days) from the germplasm AT Nar-004 and maximum (63-67 days) from the germplasm AT Nar-008. Germplasm AT Nar-004 showed less susceptible to anthracnose disease and also very low aphid infestation compare with other germplasm and check variety.

Keywords: Vegetables, Amaranth, Virus resistance, Germplasm, Soil, Fertilizer

Location: RHRS, Shipur, Narsingdi, Bangladesh

Start Date: 00-00-2017

End Date: 00-05-2018

Program Area: Crop-Soil-Water Management

Commodity: Amaranth

Objectives:

To Amaranth yield, quality and virus resistance

Methodology:

The study was conducted in the experimental field of RHRS, Shipur, Narsingdi from October 2017 to January 2018. Nine stem amaranth germplasm with one check variety were used under RCB design with three replications. Seeds were sown on 15 October 2017 at a spacing of 25 cm ´ 8 cm. The unit plot size was 3 m ´ 1 m. The field was fertilized with cowdung-N-P-K-S-@ 5 ton-20-08-16-06 kg/ha (Annon, 2012). All the organic manure, phosphorus, Sulphur and one-third of nitrogen and potassium were applied in pit 5-7 days before planting and mixed thoroughly with the soil. The remaining nitrogen and potassium were applied during 20, 35 and 50 days after planting around the plant as side-dressing under moist soil condition and was mixed thoroughly with the soil. To check insect invasion, Malathion 57 EC was applied at 2 mL/L fortnightly. Irrigation was given by watering cane if and when needed. Data on plant height and weight, stem length, leaf size, yield, days to harvest, insect pest and disease were recorded from six plants being randomly selected from each plot encompassing the avoidance of boarder effect and analyzed statistically.

Achievement/Findings:

Considering yield, yield attributes, and disease-insect reactions, the germplasm AT Nar-004 showed the best among the germplasm. This is a first-year evaluation, further studies are needed to evaluate more precisely.
