Online published on 18 May, 2022. Abstract Lentil is one of the major Rabi pulse crop grown in India. Seven soil amendments such as Pyrite and Gypsum @ 2.0 gm/kg soil and Neem cake, Mustard cake, Paddy straw and Wheat straw @ 20 gm/kg soil were incorporated in the soil eight days before sowing of healthy lentil seed of “Rath local” variety. Among the Neem cake @ 20 gm/kg soil was found significantly superior over all the treatments resulting minimum wilt disease incidence (34.80 and 35.90%) maximum disease reduction over control (57.24 and 56.25%) maximum yield (6.30 and 6.50 q/ha.) and maximum yield increase over control (186.36 and 242.10%) in the years 2018–19 and 2019–20 respectively. Wheat straw was the least effective showing maximum disease incidence of (61 and 61.53%) minimum disease reduction over control of (25.06 and 25%), minimum yield of (3.10 and 3.05 q/ha.) and minimum yield increased over control of 40.90 and 60.52% in the years 2018–19 and 2019–20 respectively. The date of sowing of the lentil seed was significantly affect the disease incidence and yield of the crops. The minimum wilt disease incidence of 10.26 and 15.30% with maximum yield of 10.95 and 10.06 q/ha was recorded when the seed was sown on 5th November, date of sowing in the years of 2019–20 and 2018–19, respectively, followed by 29th October, 22nd October, 15th October and 8th October. The maximum disease incidence (32.73 and 30%) with minimum yield (2.50 and 3.0 q/ha) was observed on the 1st October date of sowing in the years 2018–19 and 2019–20 respectively. The average wilt disease incidence was decreased with increasing crop yield at 1st October to 5th November date of sowing significantly.
