Abstract:

An investigation was carried out during kharif seasons of 2008 in rice crop with the different levels of nitrogen and various cultivars to find out best rice cultivars and optimum dose of nitrogen under terai region of West Bengal. The experiment was laid out in a factorial Randomized Block Design (RBD) with five cultivars namely, V1= MTU-7029, V2= ANNADA, V3= KHANDAGIRI, V4= SATABDI and V5= GS-3 and three levels of nitrogen: 30, 60 and 90 kg /ha. The treatments were replicated thrice. Among the cultivars V4 (Satabdi) produced tallest plant (24.46, 63.51, 77.50 and 86.49 cm at 20 DAT, 40 DAT, 60 DAT and at harvest respectively) at all the stages of taking observation. Among the cultivars V1 (MTU-7029) recorded highest number (247.28, 279.84, 212.08 and 205.33 at 20 DAT, 40 DAT, 60 DAT and at harvest respectively. Among the levels of nitrogen N3 (90 kg N/ha) produced maximum number of tillers (255.20, 280.06, 244.64 and 214.10 at 20 DAT, 40 DAT, 60 DAT and at harvest respectively). Among the cultivars V1 (MTU-7029) produced longest panicle (22.36) which was statistically at par with Khandagiri (22.13) and Annada (21.88). 1000 grain weight was higher (28.32) in V1 (MTU-7029) which was statistically at par with V2 (Annada) and V3 (Khandagiri). Among the cultivars, maximum grain yield (3.56) was produced by V1 (MTU-7029) followed by Khandagiri (3.45) Annada (3.38) and GS-3 (3.11). Cultivars MTU-7029 produced higher (4.72) straw yield which was statistically at par with Khandagiri (4.58) and Annada (4.56). Cultivars MTU-7029 registered highest values (42.67) of harvest index which was followed by Khandagiri (42.00) and Annada (41.33).
