Abstract: The field experiment was conducted on black gram (T-9) during kharif season of 2015-16 in research farm of the R.V.S.K.V.V., Gwalior, to study effect of levels and sources of phosphorous application on growth, yield and nutrient use efficiency of black gram (Phaseolus mungo L.). The experiment was laid out in RBD comprising of 8 treatments with 4 replications. Results revealed that most of the growth and yield parameters were significantly influenced by different levels and sources of P. The highest grain and straw yield were 677.6 and 1443.4 kg ha-1, respectively, in the treatment with 60 kg P2O5 ha-1 through SSP along with N30 K30 closely followed by 60 kg P2O5 ha-1 through DAP i.e. DAP (with 656.6 kg ha-1) and being significantly superior over application of 20 and 40 kg P2O5 ha-1.The phosphorus use efficiency in terms of agronomic efficiency, physiological efficiency and apparent recovery by black gram increased significantly with increasing levels and sources of P. Application of 60 kg P2O5 ha-1 had higher net returns and B.C. ratio as compared to 30 kg P2O5 ha-1. SSP applied treatments gave more net return and B.C. ratio as compared to same doses applied by DAP.
