Abstract: A field experiment was conducted for two consecutive years in the Red and Laterite Zone of West Bengal to evaluate the performance in extracting nitrogen from inherent soil pool with and without application of recommended doses of fertilizer nitrogen. Application of fertilizer nitrogen improved the performance of all the tested varieties but to different degrees. Jogen (CN-505), among the 10 tested varieties, was the best performer under both, with and without fertilizer nitrogen application, followed by those of Swarna (IET-5656), Biraj (CNM-539) and Masuri, respectively. These four varieties may be recommended for cultivation by the farmers under both the resource situations, in the rainfed lowlands of this zone.
