Author(s): S. KOLEY AND A. K. PAL
Abstract: The effects of N (0, 5 and 10 g/m2) and P (0, 4 and 8 g/m2) fertilizers, singly or in combination with N fixing bacteria (Azotobacter chroococcum and Azospirillum brasilense) and phosphate-solubilizing bacterium (PSB; Bacillus polymyxa[Paenibacillus polymyxa]), on the growth and flower yield of P. tuberosa (cv. Prajwal) were studied in Nadia, West Bengal, India, from February 2007 to January 2008. The application of 10:8:10 g NPK/m2 + Azotobacter chroococcum and 10:0:10 g NPK/m2+ PSB resulted in the greatest plant height (68.95 and 67.36 cm, respectively). The number of leaves was highest for 10:0:10 g NPK/m2 + PSB and 10:4:10 g NPK/m2 +Azotobacter chroococcum (65.45 and 64.52). Treatment with 10:8:10 g NPK/m2 +Azotobacter chroococcum resulted in the greatest spike length (92.50 cm) and number of spikes per clump (2.13). The number of florets per spike was highest for
