Abstract/ Executive Summary:

An experiment was conducted at Bangladesh Institute of Nuclear Agriculture, Mymensingh during February to May 2006 to evaluate the effect of different water logging periods on some sesame genotypes. Two factors, water logging periods (control or no water logging, 8-hour, 16-hour, 24-hour and 32- hour) and genotypes (Binatil-l, SM-5, SM-9, SM-12, SM-13) were used in the experiment. The highest plant height, maximum number of capsule, branch, leaf and seed plant^-1, 1000-seed weight, seed yield and total dry matter plant^-1 were found in the control. The values of the most parameters decreased with the increase in water logging period. The seed yield under water logging condition was in the order of 8-hour > l6-hour > 24-hour > 32-hour water logging. Binatil-l produced the lowest plant height, number of branch, leaf, capsule and seed plant^-1. SM-5 produced the highest 1000-seed weight and harvest index. SM-9 produced the highest plant height, number of leaf and capsule, seed yield and total dry matter plant^-1. SM-12 produced the highest number of seed, branch and the lowest 1000-seed weight. SM-12 showed medium yield performance. SM-12 showed better performance in respect of most of morphological, yield and yield attributes than those of other genotypes.

Keywords: Water logging, Sesame, Growth, Yield

Location: Pot yard of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh

Start Date: 00-02-2006

End Date: 00-05-2006

Program Area: Variety and Species

Commodity: Sesame

Objectives:

The objectives of the study were to assess the effect of salinity on morpho-physiological and yield attributes of sesame genotypes and to find out salt tolerant genotype.

Methodology:

An experiment was conducted with sesame at the pot yard of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during February to May 2006. Two factors, water logging periods (control or no water logging, 8-hour, 16-hour, 24-hour and 32- hour) and genotypes (Binatil-l, SM-5, SM-9, SM-12, SM-13) were used in the experiment. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Each pot contained 7.5 kg of soils collected from BINA farm. Fertilizers were applied in the amounts of urea 0.30 g pot^-1, TSP 0.35 g pot^-1 and MP 0.12 g pot^-1 at the rate of 125 kg ha^-1 urea, 150 kg ha^-1 TSP and 50 kg ha^-1 MP. Seeds of sesame genotypes were sown 23 February 2006. Water logging were imposed at 45 days after sowing. Data on morpho-physiological, yield attributes and yield were recorded. The collected data were analyzed statistically following two factor experiment in RCBD with the help of MSTAT computer packages (Russell, 1986). The mean values of the treatments were adjudged by Duncan’s Multiple Range Test (Gomez and Gomez, 1984).

Achievement/Findings:

The highest plant height, maximum number of capsule, branch, leaf and seed plant^-1, 1000-seed weight, seed yield and total dry matter plant^-1 of sesame genotypes were found in the control. The values of the most parameters decreased with the increase in water logging period. The seed yield under water logging condition was in the order of 8-hour > l6-hour > 24-hour > 32-hour water logging. Binatil-l produced the lowest plant height, number of branch, leaf, capsule and seed plant^-1. SM-5 produced the highest 1000-seed weight and harvest index. SM-9 produced the highest plant height, number of leaf and capsule, seed yield and total dry matter plant^-1. SM-12 produced the highest number of seed, branch and the lowest 1000-seed weight. SM-12 showed medium yield performance. SM-12 showed better performance in respect of most of morphological, yield and yield attributes than those of other genotypes.
