Caragabal 2024 Faba bean phosphorus rate and placement locations

Aims

To evaluate the effect of phosphorus rate (0, 5, 15 & 25 kg P/ha) and placement method (in-furrow vs broadcast and incorporated by sowing) on the growth and productivity of faba beans at Caragabal in 2024.

Key messages

Key findings

NDVI assessments were taken on 24 July as it relates with crop biomass (to a point). NDVI increased with higher phosphorus (P) rates and was higher where P was placed in-furrow compared with where it was broadcast and incorporated by sowing (IBS).
Grain yield followed a similar trend as NDVI. Yield increased from 4.1 to 4.5 t/ha as P rate increased from nil to 25 kg P/ha. Placing P in-furrow with seed gave a 0.2 t/ha yield improvement over where P was broadcast and incorporated by sowing (IBS).
