EFFECT OF NITROGEN AND BORON ON THE GROWTH AND YIELD OF SEAME

Abstract

An e periment was carried out to investigate the effect of nitrogen and boron on the growth and yield of sesame cv. T-6 at the field laboratory of Sher-e-Bangla Agricultural University Dhaka-1207. The experiment comprised four level of .. Nitrogen viz, 0 30 .. 60 and 90 Kg N ha-1 and four levels of Boron viz. 0 0.80, 1.60 and 2.40 Kg B ha". The experiment was laid out in a Randomized Complete Block Design with three replications. Results revealed that nitrogen and boron had significant effect on growth yield and yield parameters of sesame. Among the four levels of nitrogen 60 Kg N ha-1 performed the best in obtaining the highe t values in almost all parameters such as plant height ( 110.04 cm) at 60 DA .. number of capsules plant" (32.59) .. number of seeds capsule" (69.65), 1000 seed weight (2.7lg)'t seed yield ha-1 (1346.74 kg), stover yield ha" (5509.80 kg). Boron also showed significant effect on growth and yield of sesame. Boron at 1.60 Kg ha" produced the highest value in all parameters except number of leaves plant' index ( 21.83%). ABSTRACT •• Vil 1• The lowest value in the studied parameters was obtained from the control treatment. In re pect of the interaction 60 Kg N ha-1 along with 1.60 Kg B ha" gave the talle t plant (117.08 cm) at 60 DAS and produced the highest number of capsules plant" (36.05) capsule length (2.42 cm) 1000 seed weight (2.87 g), seed yield ha·1 (1628.91 kg) and harvest
