Aims

Effect of phosphorus rate and placement on plant establishment and grain yield of lentils and lupins.

Key messages

• The site chosen for the trial was a red sandy loam soil with inherent low fertility and an acidic topsoil, pH (CaCl2) 4.5.
• Establishment was reduced in both the lentil and lupin trials where phosphorus (11 and 22 kg P/ha) was placed with the seed.
• The greatest impact on establishment was in lupins where the higher P rate (22 kg P/ha) was placed with the seed.
• In the lentil trial, yield was greater where P was applied with the seed (3.25 t/ha) as opposed to IBS (incorporated by sowing, 3.09 t/ha). Yield was also higher where the higher rate of P (22 kg P/ha) was applied (3.55 t/ha), despite the reduction in plant numbers.
• In the lupin trial there were no differences in yield between P rate and P placement.
