Abstract:
The major reasons of fluctuating cost and availability of pulses are climatic abnormalities in India. The climatic abnormalities are more vulnerable on pulse crops compared with oilseeds and cereals. A study was conducted on climatic change abnormalities impact on area and productivity after 3 decades of Madhya Pradesh and Chhattisgarh states of Central India and mitigation technology on yield and benefits of black gram. Absolute and relative changes in average area was slightly increased by 49.2% against base years (1980 to 83) area (532.6 thousand ha), while productivity increased by 40.3% compared with base year yield (217.7 kg/ha). Study showed significant variability in area (CV=17.7%) and productivity (CV=13.8%) of black gram of Central India. The maximum absolute and relative increased in area was 139.1 thousand ha and 146.5% of Malwa plateau, whereas absolute and relative changes decreased in area of Chhattisgarh plain (-13.1 thousand ha) and Bastar plateau (-19.2%) compared with base years, respectively. Maximum absolute and relative change in increase in productivity of Vindhyan plateau was 285.6 kg/ha and 102.8% compared with base year average yield (258.3 kg/ha), while decreasing of absolute and relative change in productivity of Gird region compared of base years.
Results of on farm trials showed that adoptions of mitigation of technologies of climatic abnormalities significantly influenced grain yield of black gram. Study revealed that among abiotic and biotic stresses, major losses in production of grain of black gram by water submergence during rainy season (33.0%) followed by drought during grain filling stage in summer (23.2%) and yellow vein mosaic (34.8%) followed by pod borer (30.1%) compared with control, respectively. Escaping of abiotic and biotic stresses with improved technologies was enhanced grain yield from 21.4-49.2% and 43.0-53.5% compared with control, respectively. Similarly, using improved techniques for mitigation of climatic abnormalities gave higher net returns and B:C ratio compared to control.
