An experiment was conducted at BARI, Joydebpur and RARS, Jessore to find out the varietal performance of sesame under different drainage systems during the kharif season of 2002. Three varieties, T-6, BARI Til-2 and BARI Til-3 were tested under two types of drainage systems. The highest seed yield (1129.58 kg/ha) at Joydebpur and 867.77 kg/ha at Jessore) were obtained from drainage across the lower end of the plot with bed and furrow having row spacing, 45cm (D2). From the interaction effect between treatment and variety, it is seen that the above treatment in interaction with the variety, BARI Til-3 produced the highest seed yield (1286.25 kg/ha). From this study, sesame has been found to produce better yields when provided with good drainage system.

This study was undertaken to find out the varietal performance of sesame under different drainage systems.
A field experiment was conducted at BARI, Joydebpur and Regional Agricultural Research Station, Jossore during the kharif-1 season of 2002. Three sesame varieties; T-6 (V1), BARI Til-2 (V2) and BARI Til-3 (V3) were tested. Two treatments were: drainage across the lower end of the plot with row spacing of 30 cm (D) and drainage across the lower end of the plot with bed furrow having row spacing, 45 cm (D2). Soil texture in the experimental field was silty clay having bulk density of 1.50 g/cc anf field capacity of 28.0 percent at Joydebpur. At Jessore, texture was silty loam having bulk density, 1.48 g/cc and field capacity of 27.50 percent.
The experiment was laid out in a split-plot design with four replications. The varieties were placed in the main plots and the treatments in the sub-plot. The unit plot size was 3m x 5m having row spacing of 30 cm and 45 cm for treatments D1 and D2 respectively. The spacing between plants was 5 cm. The fertilizers were applied at the rate of 150 and 30 kg/ha of N, P2O5 and K2O, respectively. The whole of P2O5 and K2O together with one0-half of N were applied at the time of final land preparation. The first of N was applied at 30 days after sowing (DAS) as top dressing. Intercultural operations, like weeding and thinning were not done properly in time due to early frequent heavy rains. The seedling was done on March 14, 2002 at Joydebpur and on April 14, 2002 at Jessore. The crop was harvested on June 06, 2002 at Joydebpur and on July 04, 2002 at Jessore. All necessary data were collected and analyzed statistically.

The results indicate that drainage system can ascertain the plant growth of sesame keeping the root zone unaffected from water logging in kharif season thereby yield is increased. From the first year study, it may be seen that sesame is highly responsive to drainage.
