Abstract/ Executive Summary:

An experiment was conducted in the field of Sher-e-Bangla Agricultural University farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from February to May, 2009. The experiment consisted of two factors. 4 levels of nitrogen N₀: 0 kg N ha^-1 (control); N₁: 40 kg N ha^-1; N₂: 60 kg N ha^-1 and N₃: 100 kg N ha^-1; and 4 levels of sulfur S₀: 0 kg S ha^-1 (control); S₁: 20 kg S ha^-1; S₂: 40 kg S ha^-1 and S₃: 60 kg S ha^-1. Plant height, number of branches plant^-1, number of leaves plant^-1, seed yield, stover yield were increased significantly with increasing N level upto 60 kg N ha^-1 (N₂) . Again, these parameters were increased significantly with increasing S level up to 40 kg S ha^-1 (S₂) whereas Stover yield was increased up to 60 kg S ha^-1. Interaction effects of nitrogen(60 kg P ha^-1) and sulphur (40 kg S ha^-1 ) gave the highest number of capsules plant^-1 (70.40), length of capsule(3.99 cm) , diameter of capsule(2.77 cm), seeds capsule^-1(50.63) and thousand seed weight(12.25g). The combined application of 60 kg nitrogen and 40 kg Sulphur may be considered to be optimum for getting higher yield of sesame.

Keywords: Nitrogen, Sulfur, Sesame

Location: Field of Sher-e-Bangla Agricultural University farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh

Start Date: 00-02-2009

End Date: 00-05-2009

Program Area: Crop-Soil-Water Management

Commodity: Sesame, Fertilizer

Objectives:

To determine the effect of nitrogen and sulfur on growth and yield of sesame

Methodology:

An experiment was conducted in the field of Sher-e-Bangla Agricultural University farm, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from February to May, 2009. The characteristics of initial surface soil (0-15) were: pH 6.47, textural class silty clay loam, organicarbon 0.98%, total N 0.078%, Phosphorous 20.14 ppm and Sulfur 10.87 ppm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The size of the plot was 2.5 m × 2.0 m. The experiment consisted of 2 factors viz. 4 levels of Nitrogen N₀: 0 kg N ha^-1 (control); N₁: 40 kg N ha^-1; N₂: 60 kg N ha^-1 and N₃: 100 kg N ha^-1; and 4 levels of sulfur S₀: 0 kg S ha^-1 (control); S₁: 20 kg S ha^-1; S₂: 40 kg S ha^-1 and S₃: 60 kg S ha^-1. BARI Til-3 variety of sesame was used as a test crop in this experiment. Recommended doses of P, K, Zn and B (150 kg N ha^-1 from TSP, 50 kg K ha^-1 from MP, 5 kg Zn ha^-1 from ZnO and 1 kg B ha^-1from Boric acid, respectively) were applied. Sesame seeds were sown on the 17th February 2009. Intercultural operations were applied when necessary. The crop was harvested on 30th May, 2009. The harvested crop of each individual plots were recorded plot wise the yields were expressed in t ha^-1. Data collections were done on Plant height (cm), Number of branches plant^-1 , Number of leaves plant^-1 , Days to 1st flowering, Number of capsule plant^-1 , Length of capsule(cm) , Diameter of capsule(MM), Seeds capsule^-1, Thousand seed weight (g), Seed yield hectare^-1, Stover yield hectare^-1. The data were analyzed statistically to find out the treatment difference and the mean differences were compared by DMRT.

Achievement/Findings:

The combination of N₂S₂ treatment combination i.e. 60 kg N ha^-1 and 40 kg S ha^-1 is optimum for the best growth and yield sesame. In case of some parameters highest values were observed at the highest doses of fertilizers which were statistically similar with the results found at the treatment combination of 60 kg N ha^-1 and 40 kg S ha^-1. It may be concluded that it’s wise and economic to use the optimum dose of N and S for maximum yield of sesame.
