Assessing Production Potential of Wheat Crop (Var; Kanchan) in Raipur District of Chhattisgarh Region under Projected Climate Scenarios
Wheat (Triticum aestivum L.), being a cool season crop, is highly sensitive to increase in temperature. Global warming and climatic changes being experienced during recent decades are resulting in large oscillations in wheat productivity. Increase in minimum temperature has more adverse impact on wheat productivity as compared to maximum temperature. Climatic warming results in enhanced maturity, decrease in grain filling period and hence, reduction in wheat productivity. Similarly, water stress during reproductive growth period of wheat leads to significant reduction in grain yield. Although increase in CO 2 concentration is able to counter balance the negative effect of increase in temperature up to about 1-2°C, but increase in temperature beyond 2°C adversely affects wheat productivity even under elevated CO 2 levels. Different adaptation measures need to be adopted to manage heat and water stress in wheat under changing climatic conditions. Sowing of wheat in the first fortnight of November helps in avoiding terminal heat stress. Improved cultivation systems like zero tillage, bed planting and conventional tillage with mulch produce higher grain yield and improve water productivity of wheat than conventional planting. Irrigation management and retaining crop residue in field are other measures to manage terminal heat stress and improve water productivity in wheat. Breeding strategies need to be stressed upon for developing stress tolerant varieties in view of future climatic challenges. Agroforestry systems should also be adopted to enhance carbon sequestration and improve crop microclimate to sustain productivity under climatic fluctuations. Simulation modelling studies also need to be put in action to explore most effective climate change adaptation / mitigation strategies with respect to climatic variations over different regions. In addition to this, timely availability of accurate weather forecast and agro-advisory can be of great benefit in taking short-term management decisions as per the impending weather conditions.
