Abstract: During the period from December 2016 to May 2017 the study was carried out at the Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur in Rabi season to evaluate the efficacy of different organic and inorganic fertilizers on the growth and yield of boro rice (BRRI dhan29). The experiment had eight treatments with three replications and as follows; T0: Control, T1: 100% N75P12K45S9 (Recommended dose), T2: 50% NPKS + 6 t cowdung ha-1, T3: 75% NPKS + 3 t cowdung ha-1, T4: 50% NPKS + 6 t poultry manure ha-1, T5: 75% NPKS + 3 t poultry manure ha-1, T6: 50% NPKS + 6 t vermicompost ha-1 and T7: 75% NPKS + 3 t vermicompost ha-1. Application of organic and inorganic fertilizers resulted in a considerable influence on the growth and yield contributing characteristics of boro rice (BRRI dhan29). At harvest stage, the tallest plant (94.37 cm) and the greatest number of total tiller per hill (22.10) was recorded from T4. The longest panicle (26.48 cm), maximum number of total grain per plant (178.3), the highest weight of 1000 seeds (21.96 g), the maximum grain yield (10.33 t ha-1) and straw yield (15.67 t ha-1) was also recorded in T4 treatment. Although the highest biological yield was recorded from T4 treatment but statistically similar result was found from T5 treatment. The findings of the study showed that the performance of the treatment T4 was the best among all treatments in terms of growth and yields. So, the recommendation of this study is amendment of soil with 50% NPKS + 6 t poultry manure ha-1 might be an efficient practice for achieving sustainable higher boro rice (BRRI dhan29) production.
