Abstract/ Executive Summary:

An experiment was conducted at the MLT site, Bhuapur, Tangail during Kharif 2012 to find out the economic fertilizer dose of sesame under char land situation. Six fertilizer doses viz. T₁: 92-32-57-25-3-0.8 kg/ha NPKSZnB (based on HYG, BARC), T₂: 52-28-23-19-1.5-1 (based on BARI), T₃: 55-10-14-7-0-0 (based on AEZ-8), T₄: 107-39-32-17-3.6-0.6 (Based on Soil Test), T₅: 17.2-8-18-0-0-0 (Farmer’s practice) and T₆: native fertility were tested on BARI Til-4. Among the treatments, T₁ gave the highest seed yield (1.58 t/ha) which was at par with T₄ treatments. The highest gross return (Tk. 59250/ha) and gross margin (Tk. 19393/ha was recorded in T₁ which was very close to T₄. But the highest BCR was obtained from T₃ (1.58) due lower cost of production. The results revealed that 55-10-14-7 kg/ha NPKS would be the optimum fertilizer dose of sesame for getting the highest BCR in the charland of Bhuapur, Tangail (AEZ- 8).

Keywords: Fertilizer management, HYV sesame, Charland areas (AEZ-8)

Location: Bhuapur, Tangail

Start Date: 13-04-2012

End Date: 05-07-2012

Program Area: Crop-Soil-Water Management

Commodity: Sesame

Objectives:

To find out optimum fertilizer dose of sesame under char land situation.

Methodology:

The trial was conducted at the MLT site, Bhuapur, Tangail (AEZ- 8) during Kharif 2012. The experiment was laid out in RCB design with three replications. Unit plot size was 8m x 5m. Six fertilizer doses viz. T₁: 92-32-57-25-3-0.8 kg/ha NPKSZnB (based on HYG, BARC), T₂: 52-28-23-19-1.5-1 (based on BARI), T₃: 55-10-14-7-0-0 (based on AEZ), T₄: 107-39-32-17-3.6-0.6 (Based on Soil Test), T₅: 17.2-8-18-0-0-0 (Farmer’s practice) and T₆: native fertility were tested on BARI Til-4. Half of nitrogen and full quantity of other fertilizers were applied at the time of final land preparation in the form of urea, triple super phosphate, muriate of potash, gypsum, zinc sulphate and boric acid, respectively. Rest of nitrogen was applied as top dress at flower initiation stage (25 days after seeding). Seeds were sown in line at a distance of 30 cm from line to line on 13 April, 2012. Pests and other crop management practices were done as and when necessary. The crop was harvested during 05 to 10 July, 2012. Data on different plant characters, yield components and seed yield were recorded from randomly selected 10 plants from each plot.

Achievement/Findings:

The highest gross return (Tk. 59250/ha) and gross margin (Tk. 19393/ha) was recorded in T₁ which was very close to T₄. But the highest BCR was obtained from T₃ (1.58) due to lower cost of production. The results revealed that 55-10-14-7 kg/ha NPKS would be the optimum fertilizer dose of sesame for getting the highest BCR in the charland of Bhuapur, Tangail (AEZ- 8).
