Abstract

The effect of inoculation by Azotobacter and Phosphobacteria regarding biofertilizer on growth and yield of wheat (Triticum aestivum) was studied in experimental field of K.V.K. Allahabad (U.P) during the rabi season of 2011-12. The field trial consisted of 9 bio-fertilizer treatments viz., seed treatment with liquid PSB (Phosphate Solubilizing Bacteria) inoculants (T1 ), seed treatment with powder PSB inoculants (T2 ), soil treatment with liquid PSB inoculants (T3 ), soil treatment with powder PSB inoculants (T4 ), soil treatment with liquid Azotobacter inoculants (T5 ), soil treatment with powder Azotobacter inoculants (T6 ), seed treatment with liquid Azotobacter inoculants (T7 ), seed treatment with powder Azotobacter inoculants(T8 ) & un-inoculated(Control)(T9 ). Results showed that plant height, number of tillers/plant, number of spikes/ plant, spike length, no. of grains/spike, grain yield (kg/ha) and straw yield (kg/ha) were significantly higher in plants inoculated with seed treatment especially PSB in liquid form. Interaction effect of liquid phosphobacteria with seed treatment was a good combination. However, the maximum grain yield was recorded with application of liquid phosphobacteria followed by Azotobacter. The highest gross return (Rs. 72832/ha) and net return (Rs.64532/ha) was obtained with liquid phosphobacteria seed treatment combination.
