<p>The experiment was conducted at Regional Agricultural Research Station and Pulses Research Centre of Bangladesh Agricultural Research Institute, Ishwardi during three consecutive years of 2009-10, 2010-11 and 2011-12. Four dates of sowing (D1=25 October, D2=10 November, D3=25 November, D4=10 December) and seven varieties/lines of lentil (V1= BARI Lentil-3, V2=BARI Lentil-4, V3= BARI Lentil-5, V4= BARI Lentil-6, V5= BARI Lentil-7, V6=BLX-98001-1, V7= BLX-98002-3 were used as treatments in the experiment. Record of maximum mean number of pods per plant, production of higher 1000-seed weight, seed yield, duration of vegetative phase, duration of reproductive phase, duration for maturity, growing degree days (GDD) in vegetative phase, reproductive phase and maturity; and relationship between seed yield were evaluated. Optimum parameters and prediction of seed yield (against optimum parameters) was also computed through developed function models. Estimated optimum temperature in reproductive phase for maximum predicted seed yield, the estimated optimum sowing date for maximum predicted seed yield, the estimated GDD in maturity for maximum predicted seed yield, the estimated GDD in vegetative Phase for maximum seed yield and the estimated duration for maturity for maximum predicted seed yield were estimated. In this experiment, the results revealed that adjusted sowing of lentil is 15 November as changing environment in Bangladesh in relevant to the assessing functional models.</p>
