Nitrogen deficiency
One of the most common problems in rice production is nitrogen deficiency. It usually occurs at critical growth stages (panicle development), when plants need more N.
We can recognize these nitrogen deficiency symptoms by the strong discoloration of the crop. We can manage nitrogen deficiency through the following measures
Applying nitrogen fertilizer effectively.
Maintaining adequate plant spacing.
Proper water management. Many farmers claim that their fields should be constantly flooded.
Control weeds that compete with rice for nitrogen (very important)
Consultation with a local licensed agronomist is recommended.
