Barellan 2022 Phosphorus Management in Pulses locations

Aims

To evaluate the effect of phosphorus rate and placement on plant establishment and overall grain yield for lentil and lupin crops.

Key messages

The soil was a brown sandy loam with pHCa 5.2, Colwell phosphorus 44 ppm and total nitrogen (0–60 cm) 52.9 kg N/ha. The pulse crop grown was lupins in 2016.
There was no effect of P fertiliser rate or placement on establishment of lentils, but lupin establishment was reduced when P was placed with seed compared to P being spread and incorporated by sowing (IBS).
Early vigour of lentils (measured by NDVI on 2 August) increased with P rate and was higher when P was placed with seed compared to IBS. There was no effect of P rate on NDVI at the second assessment (31 August) but there was still a positive effect of P applied with seed compared to IBS. NDVI in lupins followed a similar trend as observed with plant establishment with negative effects of P when applied with seed.
Grain yield response was similar to the response observed with establishment. Lentil yield was not affected by P rate or placement; lupin yield was reduced where P was placed with seed.
Lentil yield averaged 2.8 t/ha. Lupin yield ranged from 4.75 t/ha where P was applied with seed to 5.6 t/ha where P was applied IBS.
