A field experiment was conducted to study the effect of phosphorus levels (0, 10, 20 30 and 40 kg P2O5 ha-1) and sulphur levels (0, 10,
20 and 30 kg S ha-1) on economics of blond psyllium (Plantago ovata Forsk) and optimum doses of fertilizers. The results showed that application
of phosphorus significantly increased the net returns and seed yield of blond psyllium up to 30 kg P2O5 ha-1. Whereas, B:C ratio significantly
increased up to 20 kg P2O5 ha-1. Application of sulphur significantly increased the net returns, B:C ratio and seed yield up to 20 kg S ha-1. A level
of 37.17 kg P2O5 ha-1 and 28.824 kg S ha-1 were found optimum doses for grain yields of 1288.54 kg ha-1 and 1260.115 kg ha-1, respectively.
