Two trials were conducted to determine the effect of phosphorus (P) rate and placement on lentils and field
peas establishment and grain yield
Key findings
• A widespread severe frost on 16 September impacted the trials in 2024,
with temperatures as low as −2.1 °C, staying below 0 °C for much of the
night.
• There was no effect of P rate on establishment, NDVI and grain yield of
both lentils and field peas in 2024.
• There was no effect of P placement on establishment, NDVI and grain
yield of both lentils and field peas in 2024 (site Colwell P 29 mg/kg).
