Discuss the sensitive stages for drought and high temperature in cereals and pulses.
Crop vulnerability to drought and high temperature varies by growth stage.
Cereals:
Germination and seedling stage: Drought delays establishment.
Tillering stage (wheat, rice): Moisture stress reduces tiller number.
Flowering and anthesis: Most sensitive stage; drought or heat causes pollen sterility.
Grain filling: Stress reduces kernel weight and yield.
Pulses:
Pre-flowering stage: Moisture stress delays vegetative growth.
Flowering stage: Drought or heat causes flower drop and poor pod set.
Pod filling stage: Stress reduces seed size and number.
Thus, flowering and reproductive phases are most critical for both cereals and pulses under climatic stress.
