Effect of Bio-Fertilizers and Sulphur on Growth and Yield of Lentil (Lens culinaris M.)

A field experiment was conducted during Rabi season (2021-2022) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of experimental plot was sandy loam in texture. The treatments consisted of Rhizobium 20 g/kg + Sulphur 10 kg/ha, Rhizobium 20 g/kg + Sulphur 20 kg/ha, Rhizobium 20 g/kg + Sulphur 20 kg/ha, PSB 15 g/kg + Sulphur 10 kg/ha, PSB 15 g/kg + Sulphur 20 kg/ha, PSB 15 g/kg + Sulphur 30 kg/ha, VAM 15 g/kg +Sulphur 10 kg/ha, VAM 15 g/kg +Sulphur 20 kg/ha, VAM 15 g/kg +Sulphur 30 kg/ha. The experiment was laid out in Randomized Block Design, with 9 treatments replicated thrice. Results revealed that the highest plant height (34.03 cm), number of nodules (11.10), plant dry weight (12.25 g/plant), number of pods per plant (163.1), number of seeds per pod (2.00), test weight (23.95g), seed yield (1.97 t/ha) and stover yield (3.75 t/ha) were significantly influenced with application of PSB 15 g/kg + Sulphur 30 kg/ha. Higher gross returns (INR 108455.00/ha), net returns (INR 75505.00/ha) and B:C ratio (2.29) were also recorded with application of PSB 15 g/kg + Sulphur 30 kg/ha.
