Wheat (Triticum aestivum L.), a staple cereal crop, is
crucial for feeding the growing human population. Biofertilizers play a major
role in increasing nutrient availability for high yield, making them a
sustainable alternative or supplement to chemical fertilisers. The objective of
this study was to evaluate the co-inoculation effect of Azospirillum
Brasiliense and Bacillus subtilis on growth, yield and nutrient uptake of
wheat. A field experiment was conducted to study the effect of Azospirillum
brasilense and Bacillus subtilis along with a graded level of chemical
fertilisers on growth, yield and nutrient uptake of wheat (Triticum aestivum)
during Rabi, 2018, at the Agronomy farm, Rajarshee Chhatrapati Shahu Maharaj
College of Agriculture, Kolhapur. The plots were arranged in a randomised block
design with three replications. The co-inoculation effect of Azospirillum
brasilense and Bacillus subtilis, along with 75% nitrogen and Phosphorus and
100% potassium, recorded the highest plant height at tillering (25.00), plant
height at flowering (87.80cm), plant height at maturity (90.53cm), number of
tillers sq.m1 (403.00). In addition, ear length (14.77cm), number of spikelets
ear-1 (42.87), number of grain ear-1 (38.33),1000 grain weight (43.88gm), gram
yield (50.63q/ha), straw yield (75.93 q/ha) and uptake of nitrogen and
phosphorus by wheat plant were also found to be increased 120.00 kg hand
37.00kg/ha respectively. The results of the present investigation clearly
demonstrate that co-inoculation of wheat seeds with Azospirillum brasilense and
Bacillus subtilis, combined with 75% of the recommended nitrogen and phosphorus
and 100% potassium fertiliser, produced results similar to the full 100% NPK
treatment. This suggests that 25% of nitrogen and phosphorus fertilisers can be
effectively replaced, leading to significant savings in chemical fertiliser
costs without compromising crop performance.
