Abstract: The effects of different levels of nitrogen and boron fertilizer were determined on the yield and yield components of winter Chilli (Capsicum annum L) using different levels of nitrogen viz., 0, 20, 40, 60, 80, 100, 120 and 140 kg ha-1 and three levels of boron viz., 0, 1.5, 2.5 kg ha-1. The highest chilli yield (dry) was obtained from 120 kg N ha-1 (2.41 ton ha-1 in 1997-98 and 2.77 ton ha-1 in 1998-99) which differed significantly from other nitrogen levels. The yield was progressively increased with the increased levels of nitrogen up to 120 kg N ha-1 and there after it was declined. Among different levels of boron, the highest yield was obtained from 2.5 kg B ha-1 which was identical to 1.5 kg B ha-1. Interaction effects between nitrogen and boron on the chilli yield were found significant. In both the years, the highest chilli yield was recorded from 120 kg N ha-1 when applied with 2.5 kg B ha-1 which was identical to 120 kg N ha-1 when applied with 1.5 kg B ha-1.
