Abstract
Field experiments were carried out during wet season of 2007 and 2008 at Regional Research Sub-Station of Bidhan Chandra Krishi Viswavidyalaya, West Bengal to find out the response of hybrid rice to planting geometry and different levels of nitrogen. The experiment was consisted of 9 treatment combinations with three different levels of nitrogen and three different spacings. Hybrid rice variety ‘Pro Agro 6201’ was taken as the test crop. The experimental result revealed that different planting geometry and level of nitrogen had a remarkable influence on almost all the yield attributing characters and yield of hybrid rice. Different yield attributing characters viz. number of effective tillers m−2, panicle length, filled grains panicle−1 and test weight were increased significantly with the increasing level of nitrogen from 50 to 150 kg ha−1. On the other hand, closer spacing (15cm x 15cm) produced significantly higher grain yield (6.00 t ha−1).
