to study the effect of salicylic acid and potassium nitrate on growth and yield of lentil under rainfed condition. Seed priming with salicylic acid (200 ppm) enhanced the plant height, number of branches, fresh and dry weight and number of nodules per plant and yield attributes namely number of pods per plant and seeds per pod. Foliar spray of KNO 3 (2.0 %) foliar application significantly enhanced the growth attributes of lentil for all the growth stages except for 30 days after sowing (DAS).

The treatment combination of salicylic acid (200 ppm) and KNO 3 (1.5%) gave the maximum grain yield (1104.88 kg/ha), stover yield (1799.06 kg/ha) and biomass yield (2903.95 kg/ha). It can be inferred that seed priming of salicylic acid (200 ppm) and foliar application of potassium nitrate (2.0 % and 1.5%) increases the growth and yield of lentil.
