Paddy stage by stage
Paddy is grown in standing water, which changes how nutrients behave in the soil. Growers bring us weak tillering, yellowing after transplanting and chaffy, poorly filled grain.
Main growing areas: West Bengal, Uttar Pradesh, Punjab, Andhra Pradesh, Odisha, Tamil Nadu and Gujarat.

Tillering
About 1 to 2 monthsThe number of tillers decides the number of panicles.
Panicle and flowering
About 2 to 3 monthsStress now reduces grains per panicle.
Grain filling
Last monthGrain weight builds up; leaf health matters most.
