• Common diseases include leaf blight, stripe smut, and rust.

Additional information:

• Leaf blight: Causes yellow/brown lesions on leaves, reduces photosynthesis.
• Stripe smut: Fungal disease producing black streaks on stems and leaves.
• Rust: Includes leaf rust, stem rust, and stripe rust; reduces grain quality and yield.

• Legumes can fix atmospheric nitrogen through root nodules, so additional N is minimal.
• Proper nitrogen application supports early growth and improves yield.

• Shorter wheat plants are less likely to fall over (lodging) under high fertilizer use.
• This gene played a key role in the Green Revolution, increasing wheat yields worldwide.
