RESPONSE OF SESAME (Seswnuni indicum) TO VARYING LEVELS OF MANAGEMENT PRACTICES

Abstract

The experiment was conducted at the research field or Agronomy Department of Sher-c-Bangla Agricultural University. Dhaka during the period of March to June, 2008 to find out management practices suitable to boost up the seed yield. The experiment comprised of ten treatments viz. T Broadcast sowing without post sowing care (control). T2 = Broadcast sowing ± one hand weeding (I 11W) at 20 DAS, T3 = Broadcast sowing + recommended Fertilizer (46-72-30-20-2-1 kg N . P,Oi. K20. S, B and Zn had), It= Broadcast sowing ± recommended fertilizer + I 1-lW at 20 DAS. Tc Broadcast sowing + recommended fertilizer + 1 11W at 20 DAS + insect control at 45 DAS. T (t- Line sowing without post sowing care ,

Line sowing -F 1 11W at 20 DAS. l= Line sowing + recommended fertilizer. 19= Line sowing •+ recommended fertilizer ± I HW at 20 DAS , T l o= Line sowing ± recommended fertilizer + 1 I-lW at 20 DAS -F insect control at 45 DAS. The trial was set tip in Randomized Complete Block Design (RCBD) with four replications. The dillerent management practices exhibit significant influence on the growth, yield and yield attributes of sesame. Significantly highest seed yield (1.33 i hi) was obtained from T10 treatment (Line sowing + recommended fertilizer + I HW at 20 DAS -- insect control at 45 DAS) due to maximum capsules branch' (10.88), capsules plani' (58.45), seeds capsuled (69.17) and harvest index (32.62%) of sesame. The yield increase due to line sowing with fertilizer, hand weeding and insect control 195% than control (T 1 ). Broadcast and line sowing without any post sowing care produced significantly the lowest yield. On the other hand, line sown crop always showed better performance than broadcast sown crop. The results indicated that line sowing with 46 kg N. 72kg P 205 30 kg K 20. 20 kg S. 2 kg B and 1 kg Zn ha S ' one hand weeding at 20 DAS and insect control at 45 DAS would he beneficial or optimum for obtaining higher yield of sesame.
