The experiment was conducted at the Agronomy research field of Sylhet Agricultural University, under the Agro-Ecological Zone of Eastern Surma-Kushiyara Floodplain (AEZ 20) during Rabi season of (November, 2012 to February, 2013). The experimental field situated at 24° 54′ 33.2″ N latitude and 91° 54′ 7.15″ E longitude at the elevation of 30m above the sea level. The soil belongs to the “Khadimnagar” soil series sandy loam in texture having moderate organic matter content (1.45%), N 0.80%, K 0.07 m mol/100g of soil, P was 25 µg/g of soil and S was 10 µg/g of soil with pH value 5.2. The experiment was laid out in an RCB (Randomized Complete Block) design with three replications. Eight varieties namely Improved Tori, TS-72, BARI Sarisha-8, BARI Sarisha-9, BARI Sarisha-12, BARI Sarisha-14, BARI Sarisha-15, and Binasarisha-4 and four advanced lines BC-05115 Y, BC-05117 Y, BC-05118 Y and Nap-205 of rapeseed mustard were tested in this experiment. Seeds were collected from the Bangladesh Agricultural Research Institute (BARI) and the Bangladesh Institute of Nuclear Agriculture (BINA). The experimental plots were fertilized at the rate of 128.8, 36, 45, 28.8, 2.21, 1.38 kg N, P, K, S, B and Zn/ha respectively.
During final land preparation, half of the urea and total amount of all other fertilizers were applied and incorporated into soil and the rest of the urea was top-dressed at 24 days after sowing (DAS). Sowing was done on November 27, 2012. Seeds were sown in line with a spacing of 25 cm × 5 cm and the area of each unit plot was 10 m2 (4 m × 2.5 m). Two hand weeding were done at 14-15 DAS and 24-25 DAS manually. Light irrigations were given one at 20 DAS and another at 40 DAS. The crop was sprayed with Malathion 57 EC to control aphids at the siliquae formation stage.
