Wheat is crop of cool environment. However, it requires different temperatures at different stages of plant growth and development. Temperature requirement may slightly differ from one variety to another at the time of germination, however, general minimum temperature is required from 3.5-5.50 c and optimum 20-250 and maximum temperature is 350 . On temperature below or above to optimum, germination of seed decreases slowly. If temperature is more than 300 c at the time of maturity it leads to force maturity and yield loss. Winter wheat bears cold waves and frost in a better way in comparison to spring wheat.
