Abstract/ Executive Summary:

A pot experiment was conducted with seven sesame genotypes viz., Rajshahi Khoyeri, Kistotil Chapai, Kathtil Chapai, Gopalgonj MV-40, Gopalgong Black, Kalotil Gopalgong and Laltil Gopalgonj at BINA farm, Mymensingh during March to June 2017. Four water logging treatments viz., Control, 24, 48 and 72 hours were imposed at flowering stage of the sesame genotypes. Plant height, number of branches, capsules and seeds plant^-1, number of seeds capsule^-1, total dry matter plant^-1, 1000-seed weight, seed yield plant^-1, photosynthesis, nitrate reeducate activity were significantly decreased with increasing water logging periods. Four sesame genotypes viz., Rajshahi khoyeri, Kistotil Chapai, Kathtil Chapai and Laltil Gopalgonj showed higher yield than others under the treatments.

Keywords: Sesame, Water logging, Morpho-physiological parameters, Yield

Location: BINA, Mymensingh

Start Date: 01-03-2017

End Date: 30-06-2017

Program Area: Crop-Soil-Water Management

Commodity: Sesame

Objectives:

To assess the effect of water logging on morpho-physiological parameters and yield of sesame genotypes and to identify water logging tolerant genotype

Methodology:

A pot experiment was conducted with seven sesame genotypes viz., Rajshahi Khoyeri, Kistotil Chapai, Kathtil Chapai, Gopalgonj MV-40, Gopalgong Black, Kalotil Gopalgong and Laltil Gopalgonj at BINA farm, Mymensingh during March to June 2017. The sesame land races were collected from different agro- ecological zones of Bangladesh. The objective of the study was to find out the water logging tolerant genotypes. Four water logging treatments viz. control and water logging periods of 24, 48 and 72 hours were imposed at flowering stage of the sesame genotypes. Each pot contained 8 kg soil collected from BINA farm. Urea, TSP, MP and Gypsum were applied 125, 150, 50 and 110 kg ha^-1, respectively. Half of urea and all other fertilizers were mixed with pot soils and remaining urea was applied at 30 days after sowing. After seedling establishment one seedling was allowed to grow in each pot. The experiment was laid out in completely randomized design with three replications. Data on plant height, number of branches, capsules and seeds plant^-1, number of seeds capsule^-1, shoot dry weight, root dry weight and total dry matter plant^-1, 1000-seed weight, seed yield plant^-1, SPAD reading, photosynthesis and nitrate reeducate activity were recorded. Data were analyzed statistically and DMRT was used to compare the means.

Achievement/Findings:

Water logging generally affected growth and yield of sesame genotypes. However, four sesame genotypes viz., Rajshahi khoyeri, Kistotil Chapai, Kathtil Chapai and Laltil Gopalgonj showed better tolerance to water logging than other three genotypes.
