Lentil (Lens culinaris Medikus) is an important winter season grain legume crop, mostly grown on residual soil moisture and is frequently subjected to terminal drought and heat stress, that results in low and variable seed yields. Moreover, delay in sowing even for two weeks causes the reproductive and grain filling phase of this crop to coincide with a period of substantially high temperature resulting in yield losses by reduced seed set, seed weight and accelerated senescence. With this background, an experiment was conducted to study the effect of terminal drought and heat stress on some genotypes of lentil. The experiment was laid out in split plot design with three replication and the experiment was conducted in District Seed Farm, AB Block, Kalyani, Nadia. Data were recorded on seed yield and its important attributes like plant height, days to 1st flower, days to 50% flowering, number of pod /plant, hundred seed weight shelling percentage [calculated as (seed wt/pod wt)×100] harvest index and days to harvest. And for harvest records five plants from each replication were randomly selected. Evaluation of lentil genotypes was done on basis of late sown (YS) and normal sown (YP) conditions and indexes of drought tolerance such as mean productivity (MP), tolerance against stress (TAS), geometric mean productivity (GMP), and stress tolerance index (STI).
