A field experiment was carried out at Bhubaneswar during 2013–14. Rice-rice sequence was previously taken for six consecutive years with seven organic nutrient management treatments in Randomized Block Design in the same plot. Organic nutrient management expressed significant effect on plant height, number of tillers per hill, effective tillers, root volume per hill, leaf area index (LAI) etc. Plant height was found the highest in treatment receiving Dhanicha + FYM + vermicompost (split) in kharif and corresponding treatment receiving FYM + vermicompost (split) in summer (T₅) at 90 DAT (121.90 and 120.08 cm, respectively). Tiller number also followed the same trend (number of tillers per hill at 45 DAT i.e. 30.67 and 30.59 in kharif and summer, respectively in T₅). The conversion of maximum tiller to effective tiller was the maximum for T₅ in kharif (84.87%) and T6 in summer season (84.34%). At 75 DAT, the root volume per hill was found the highest in T₅ i.e. 86.78 and 86.02 cc, respectively. Highest leaf area index was recorded in the same treatment in kharif and summer at 60 DAT (5.48) and (5.47) respectively.
