Agronomy QUESTION #2036

Question 4489

Physiological maturity in cereal crops is best identified by:

The date 30 days after heading
Formation of the black layer at the base of the grain (in maize) or when grain moisture reaches 30–35% and maximum dry weight is achieved✔️
When the entire crop canopy turns golden yellow
When combine harvester settings indicate optimum grain moisture

Correct Answer Logic:

Physiological maturity marks the cessation of dry matter accumulation in the grain. In maize it is identified by the black layer (abscission layer) at the kernel base. In wheat/rice, grain moisture of 30–35% at maximum dry weight is the indicator — harvesting before this causes yield loss; after causes field losses.
