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 5~(th) November, date of sowing in the years of 2019-20 and 2018-19, respectively, followed by 29~(th) October, 22~(nd) October, 15~(th) October and 8~(th) October. The maximum disease incidence (32.73 and 30%) with minimum yield (2.50 and 3.0 q/ha) was observed on the 1~(st) 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 1~(st) October to 5~(th) November date of sowing significantly.
