Detection and Management of Abiotic Stresses in Wheat Using Remote Sensing Techniques

Wheat is a photo-insensitive and thermosensitive long day plant. It requires cool climate during the early part of its growth. Temperature plays a dominant role for wheat production in India. Both the start and end of wheat crop season are limited by temperature regimes. Within the growing season itself, warmer temperature shortens the vegetative crop duration. Wheat grain yield and quality are also influenced by temperature regimes during different phases of crop growth. High temperature during early vegetative phase results in sparse tillering, poor vegetative growth and early heading; and during grain filling phase it leads to forced maturity (Reddy 2006). The IPCC (2014) has reported the globally averaged combined land and ocean surface temperature of 0.85°C over the period 1880 to 2012. The warming is more pronounced over land areas with a maximum increase over northern India. Increased concentrations of greenhouse gases and warming will have serious consequences like increased evaporation, uncertainty of International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 8 (2017) pp. 616-628 Journal homepage: http://www.ijcmas.com
