A field experiment was conducted at Regional Research Sub Station (RRSS), New Alluvial Zone, Chakdah, Nadia, West Bengal during boro season (2013-2014) to study the effect of varying levels of nitrogen and planting geometry on high yielding boro rice. The experiment was laid out in factorial randomized block design (FRBD) replicated thrice. The treatments comprised of 4 nitrogen levels (0, 100, 120 and 140 kg N ha-1) and three planting geometry (15 cm x 15 cm, 20 cm x 15 cm and 20 cm x 20 cm). The treatment receiving 140 N kg ha-1 gave the highest growth attributes such as plant height (101.81cm), number of tiller m-2 (444.08) and dry matter accumulation (DMA) (815.58 g m-2) which was statistically at par with 120 N kg ha-1. Maximum plant height (100.03 cm) was obtained at 20 cm x 20 cm. However, maximum number of tillers hill-1 (473.62) and DMA (847.33 g m-2) were observed at 15 cm x 15 cm. Yield attributes like number of panicles m-2 (304.00), number of filled grains panicle-1 (124.52) and panicle length (24.53 cm) were found maximum with nitrogen level of 120 kg ha-1. Grain yield increased gradually with increasing level of nitrogen up to 120 kg N ha-1 (4.54 t ha-1) and the plant spacing of 20 cm x 15 cm gave the highest grain yield (4.16 t ha-1).

Keywords: Boro rice, New alluvial zone, Nitrogen level, Planting geometry, Shatabdi (IET 4786).
