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

A field 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.
