A field experiment was conducted during kharif, 2016 in the experimental farm of Bidhan Chandra Krishi Viswavidyalaya to assess the effect of inorganic and bio-fertilizers on root characteristics as well as different growth and yield parameters of rice. The results revealed that the highest root length, root dry weight, plant height (105.60 cm), leaf area index (3.81), panicle length (24.50 cm), number of tillers hill-1 (15.19), effective tillers hill-1 (13.60), spikelets panicle-1 (94.68), filled grains panicle-1 (127), test weight (20.10 g) were observed in 100% RDF (T2) which was statistically at par with 75% recommended dose of NP + 100% RDK + Azotobacter chroococcum @ 5 kg ha-1 (T4) and 75% recommended dose of NP + 100% RDK + Bacillus polymyxa @ 5 kg ha-1 (T5). Similarly, T2 treatment recorded the maximum grain and straw yield (5.66 t ha-1 and 6.99 t ha-1 respectively) and all these were at par with T4 and T5, exhibiting better potential in improving crop growth and yield parameters of rice in new alluvial zone of West Bengal.
