A study was conducted for two consecutive years (2012-2013 and 2013-2014) to assess the performances of sixteen pre-released and two standard varieties of bold seeded lentil on different weather factors, for their growth and productivity potential. Growing Degree Days (GDD) requirement for vegetative stage differ from 715.8 to 1077.3 day degree Celsius, in first year and 667.7 to 698.9 day degree Celsius in second year. For completion of reproductive stage GDD requirement was 513.5 to 1016.8 day degree Celsius in first year and 644.6 to 1056.9 day degree Celsius in second year. Heliothermal Unit (HTU) requirement for vegetative stage differ from 5343.6 to 7358.7 day degree Celsius hour in first year and 4737.8 to 4777.8 day degree Celsius hour in second year. HTU requirement also differ in two years. In first year HTU requirement was 4076.5 to 7300.0 day degree Celsius hour and 5987.9 to 11803.7 day degree Celsius hour in second year. Significant differences were observed in plant height, dry matter accumulation, yield and yield attributes of the crop. The dry matter accumulation was better in the second year. The seed yield was maximum in PL-129 in both the year. The second year yield was lower than the first year, as it was exposed to higher temperature during the reproductive phase of the crop. The maximum productivity of lentil would be archived when the maximum and minimum temperature during 100% flowering ranged from 24.6 to 28.6 and 10.1 to 10.9ËšC in two years respectively.
