Abstract:

Different aspects of climate change, such as higher atmospheric CO2 concentration, increased temperature and changed rainfall patterns have different effects on crop yields. In combination, these effects can either increase or decrease crop production as the net effect of climate change on crop yield depends on the interactions between these factors. Among all changes, temperature plays a dominant role for wheat production in India. The high temperature stress at reproductive phase of crop results in poor yield due to reduced number of grains per spike and shriveled grains with poor quality. Along with thermal stress, the continuous availability of nutrients to wheat during various phases of its growth and development is important factor which influences the grain yield. So suitable production strategies for obtaining higher yield under stress conditions need to be developed for detection of these stresses at early stages of crop growth. Among these strategies, remote sensing techniques provide a platform for which plant stress and growth response can be evaluated. Variation in spectral reflectance under different type of stresses in the form of spectral vegetation indices allows us to develop suitable strategies for reducing these stresses and helps in maximizing the wheat yield. The impact of these stresses on wheat productivity can be minimized by adoption of various agronomic management practices as time of sowing, alternative method of planting, nutrient management, mulching, seed priming, foliar spray of salts and foliar spray of micronutrients to mitigate the high temperature effect on the productivity of wheat.
