Responses to deep placement of phosphorus and potassium in mungbeans—Dululu locations
Aims

This project is gathering data from these trial sites to ascertain whether an application of P or K placed as a band in the subsurface profile can provide a grain yield benefit and whether that benefit (response) can be maintained over several years.

Key messages

1. Mungbeans did not respond to deep phosphorus treatments.
2. Mungbeans had a 15% yield response to deep potassium treatments.
3. After 3 years of cropping the return on investment to 20 kg deep banded phosphorus is 1.6 and 100 kg deep banded potassium is 1.7.
