GROWTH, YIELD AND OIL CONTENT OF SESAME (Sesanium indkumL.) AS INFLUENCED BY SULPHUR AND BORON FERTILIZATION

Abstract

An experiment was carried out at the research field of Sher-e-Bangla Agricultural University, Dhaka to investigate growth, yield and oil content of sesame under different level of fertilization of sulphur and boron during summer season of 2008. Four levels of sulphur viz. 0, 9, 18 and 27 kg hi'and four levels of boron viz. 0, 1, 2 and 3 kg hi' were used as treatment variables. The experiment was laid out in randomized complete block design (factorial) with three replications. Results revealed that both sulphur and boron had significant effect on most of the growth, yield and yield parameters of sesame. Application of 27 kg S hi' showed the highest seed yield (1.19 t hi) by producing higher number of branches plant', capsules plant', seeds capsule ' and 1000- seed weight. On the other hand, 2 kg B hi'

showed its superiority by producing the highest seed yield (1.20 t hi') as well as the highest yield contributing characters. The result also indicated that combination of 27 kg S hi' and 2 kg B hi' produced the highest amount of oil content (42.07% and 41 .01%, respectively). Plant height, leaves dry weight plant weight plant', stem dry weight plant', capsule dry weight plant 4, number of branches plant', number of capsule plant', number of seeds capsul& 1, 1000- seed weight, seed yield, stover yield, oil content and harvest index increased significantly by the combining effect of 27 kg S hi' and 2 kg B hi'.
