Abstract:
A field experiment was carried out during Rabi, 2020 at crop research farm of SHUATS, Prayagraj to study about the response of biofertilizers and phosphorus levels on growth and yield of Wheat (Triticum aestivum L.) The experiment was laid out in randomized block design. using two factors, Biofertilizers i.e., Azotobacter and Azospirillum and Phosphorus levels i.e., P₁ - (50 kg/ha), P₂ – (60 kg/ha) and P₃ – (70 kg/ha) which was replicated three times. Results revealed with that the treatment of Azospirillum + 70 kg/ha Phosphorus recorded significantly highest in plant height (83.84 cm), number of tillers per m² (248.00), dry matter accumulation (614 g/m²), effective tillers per m² (229.33), number of grains per spike (44.62), test weight (33.22 g), grain yield (4.02 t/ha) and stover yield (5.16 t/ha). However, maximum Net returns (72002.50 INR/ha) and B:C ratio (2.52) were also obtained with the application of Azospirillum + 70 kg/ha Phosphorus. Therefore, concluded that Azospirillum + 70 kg/ha Phosphorus recorded significantly higher compared to other treatments.
