6.2.9.1 Effect of Cold Wave on Agriculture

The extent of damage caused by cold wave depends on temperature, length of exposure, humidity levels, and the speed at which freezing temperature is reached. It is difficult to predict a definite temperature level up to which crops can tolerate cold wave/frost because many other factors also affect it. Frost and cold waves greatly impact pulse crops. During flowering stage, these crops are likely to be adversely affected at a temperature of −2 to −3 °C. Those in podding stage are a bit more tolerant but are likely to be damaged at a temperature of −3 to −4 °C. As pulses often mature from bottom of the plant to the top, frost injury may be much greater on plant tops.
