Ranked by expected yield recovery

Why B21 is below plan

Confidence94%

Forecast 25.2 vs 25.9 t/ha (−2.7%). Largest negative driver: Rainfall deficit (3-mo lag) (-0.45 t/ha). Recommended actions below are ranked by expected recovery.

Moisture conservation

Spread EFB mulch (40 t/ha) in inter-rows; prioritise K to support drought tolerance.
