EFFECT OF SOWING METHODS AND VARIETY ON YIELD AND YIELD COMPONENTS OF SESAME

Abstract

The experiment was conducted at the Agronomy farm of Sher-e-Bangla Agricultural University, Dhaka during March to June 2017 to study the effect of sowing methods and variety on yield and yield components of sesame. The experiment comprised of four varieties viz. BARI til 2, BARI til 3, BARI til 4 and

ii

Lal til (local) designed V 1,

and

V 4 respectively combined with three sowing methods named Broadcasting, Line sowing and Line sowing on ridges designed M 1 , M 2 and M 3 . The experiment was laid out in Randomized Complete Block Design (RCBD) with 3 replications. In terms of varietal performance, the highest dry weight plant -1 (27.35 g), number of capsules plant

(47.89), number of seeds capsule -1 (62.34), seed weight plant -1 (8.10 g), 1000 seed weight (2.64 g), seed yield (1265.00 kg ha -1 ), stover yield (1601.33 kg ha ), oil yield (550.80 kg ha -1 ) and harvest index (44.06%) were achieved from BARI til 4. All the studied parameters were found lowest with Lal til (local). In case of sowing methods, line sowing showed the best performance on dry weight plant -1 (26.33 g), number of capsule plant -1 (42.94), number of seeds capsule -1 (56.39), seed weight plant (6.47 g), 1000 seed weight (2.55 g), seed yield (1103.70 kg ha -1 -1 -1 ), stover yield (1460.67 kg ha ), oil yield (480.32 kg ha -1 ) and harvest index (42.67%). Broadcasting method showed the lowest performance on the same parameters mentioned. On the other hand the interaction of the variety with sowing methods, the highest dry weight plant -1 (30.36 g), number of capsules plant -1 (56.33), number of seeds capsule -1 (67.67), seed weight plant (10.5 g), 1000 seed weight (2.75 g), seed yield (1368.00 kg ha -1 -1 ), stover yield (1635.00 kg ha ), oil yield (598.10 kg ha -1 ) and harvest index (45.56%) were found from treatment combination of V 3 M 2 where treatment combination of V 4 M 1 showed lowest results in most of the cases.
