The experiment was laid out in a RCBD with three replications. Five aromatic rice varieties (V1: Kalizira, V2: Muktasail, V3: Nagrasail, V4: Maloti and V5: Chinigura) and four levels of fertilizer (F1: Recommended dose i.e. 45-10-20-10-0.5 kg ha of recommended dose, F3: 1/3 -1 rd of N-P-K-S-Zn, F2: 2/3 rd of recommended dose, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn sources, respectively. All fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). With few exceptions, all of the growth and yield contributing characters of the aromatic rice varieties were significantly affected by the application of different fertilizer doses. The longest plant (124.5 cm) at harvest was found in Muktasail whereas the shortest plant (91.40 cm) was noted in Kalizira variety. The highest tiller number hill -1 (8.67) was noticed in Chinigura variety. The highest grain yield was recorded in Nagrasail variety (65.33 g pot (25.00) was observed in Kalizira but the lowest number of tiller hill -1 -1 ) at recommended dose of fertilizers while the lowest yield (24.31 g pot ) followed by Kalizira (65.26 g pot -1 ) was observed in Maloti with no fertilizer. Straw yield was the highest (174.07 g pot -1 -1 ) in Maloti at recommended dose of fertilizers but the lowest (61.70 g pot -1 ) was recorded in Kalizira variety with no fertilizer. Mostly Kalizira and Nagrasail varieties showed the highest nutrient (N, P, K, S and Zn) content and uptake in grain and straw at recommended dose of fertilizers while Chinigura was observed to have the lowest in control treatment. In case of post harvest soil nutrient analyses, soil containing Kalizira or Chinigura variety associated with recommended dose of fertilizers showed the highest nutrient status. The overall results indicated that recommended dose of all chemical fertilizers may optimize the production of aromatic rice. 2016-12-01T00:00:00Z
