Abstract: A study was conducted on climatic abnormalities impact on area and productivity during 3 decades of Madhya Pradesh and Chhattisgarh states of central India and mitigation technology influence on yield and economic benefits of lentil. Statistical analysis showed that absolute and relative changes in average area was slightly increased by 8.0 thousand ha and 0.8% against base years (1980 to 83) area (286.7 thousand ha), while productivity increased by 73.0 kg ha^-1 and 35.3% compared with productivity of base year (313.0 kg ha^-1), respectively. Study showed significant variability in area (CV=17.3%) and productivity (CV=23.7%) of central India. The maximum area increased in Vindhyan plateau (35.4 thousand ha), whereas decreased in Kymore plateau and Satpura hills (-25.7 thousand ha), while relative changes were maximum in Gird region (108.8%) and decreased in Satpura plateau (-41.8%) compared with base years. Maximum absolute change in productivity was of Vindhyan plateau (221.3 kg ha^-1), whereas it decreased in case of Satpura plateau (-17.0 kg ha^-1) and similar trend was observed in relative changes compared to base years. Results of trials showed that adoptions of technologies were neutralized the effect of climatic abnormalities. Study revealed that seed yield losses of lentil were from 19.6 to 40.0% with abiotic stresses, while 11.6 to 18.8% with biotic stresses compared with mitigation technologies. Escaping of abiotic and biotic stresses with improved technologies enhanced seed yield from 24.3 to 66.7% and 13.2 to 23.2% compared with control, respectively. Similarly, using improved techniques for mitigation of climatic abnormalities gave significantly higher economic benefits compared to control.
