🌿 Leaf Area Duration (LAD) Calculator
What is Leaf Area Duration?
Leaf Area Duration (LAD) represents the persistence of leaf area over time. It integrates leaf area index with duration and indicates the crop’s photosynthetic capacity.
Formula Used
LAD = (LAI₁ + LAI₂) ÷ 2 × (t₂ − t₁)
Where:
• LAI₁ = Leaf Area Index at time t₁
• LAI₂ = Leaf Area Index at time t₂
• t₂ − t₁ = Time interval (days)
Enter Observations
Interpretation:
• Higher LAD → longer photosynthetic activity
• Strongly correlated with dry matter production
• Used in crop growth analysis & yield prediction
• Higher LAD → longer photosynthetic activity
• Strongly correlated with dry matter production
• Used in crop growth analysis & yield prediction
