In laboratory experiment, dynamics of various P fractions were studied with enriched rock phosphates with Phosphobacteria. The treatment, TRP EnFYM with PB recorded highest quantity of all the P fractions irrespective of soil type and were comparatively superior over MRP EnFYM with and without PB. The PB favourably influenced various P fractions irrespective of soils and rock phosphates. In field experiments, the grain yield of maize was highest (6.62 t/ha) in 100 % P as TRP EnFYM with PB (T14) over SSP in black calcareous soil. The highest phosphorus use efficiency, physiological efficiency a...
In laboratory experiment, dynamics of various P fractions were studied with enriched rock phosphates with Phosphobacteria. The treatment, TRP EnFYM with PB recorded highest quantity of all the P fractions irrespective of soil type and were comparatively superior over MRP EnFYM with and without PB. The PB favourably influenced various P fractions irrespective of soils and rock phosphates. In field experiments, the grain yield of maize was highest (6.62 t/ha) in 100 % P as TRP EnFYM with PB (T14) over SSP in black calcareous soil. The highest phosphorus use efficiency, physiological efficiency and B:C ratio were highest in T14. In red non-calcareous soil, highest grain and stalk yields were observed in T2 (100% P as SSP) and it was on par with T8 (100% P as MRP EnFYM with PB). The increase in P levels increased the grain and stalk yield.The PUE was highest in T2 followed by T8 and the increasing levels of P recorded increase of PUE. The physiological efficiency was highest in T2. The highest response ratio was registered in T6. The highest B:C ratio was recorded in T7 followed by T8.
