Effect of integrated phosphorus management on growth, yield and quality of lentil (Lens culinaris)

Afield experiment was conducted during Rabi season of 2012–13 and 2013–14 to study the effect of integrated phosphorus management on growth, yield and quality of lentil. The trial was laid out in split plot design assigning 8 treatments of three phosphorus levels (0, 40 and 80 Kg ha⁻¹), three mode of PSB application (soil application, seed inoculation including control) and sulphur application of 20 Kg ha⁻¹ with control. The crop was fertilized up to 80 Kg ha⁻¹ of phosphorus application enhanced more growth, yield attributes, seed yield and protein yield than the 40 Kg ha⁻¹ and control, however the initial plant population per running meter was remain non-significant during both the years. The PSB applied by seed inoculation and 20 Kg ha⁻¹ sulphur application were showed similar effects. The economic value also calculated to judge best combination and found that the 80 Kg ha⁻¹ phosphorus application, seed inoculation with PSB and 20 Kg ha⁻¹ sulphur application received more net income (ha⁻¹) and benefit cost ratio also.
