The demonstration trials in this report were sown as part of a GRDC investment aiming to improve the nitrogen fixation of winter pulse crops and to promote their wider adaptation and adoption. The project involves promoting effective inoculation and pulse management practices, raising awareness and knowledge around pulse nodulation and nitrogen fixation as well as the impact of soil acidity on crop yields.
Key messages
• Where there was no paddock history of chickpea and an absence of suitable rhizobia, doubling the inoculation rate resulted in the highest level of nodulation. • A lentil crop sown in a paddock (pH 4.8–5.2) with a low background level of lentil rhizobia had good nodulation, demonstrating that not all paddocks are responsive to inoculation. • At St James, the combination of seed inoculation and Calciprill® (granulated calcium carbonate) at depth resulted in the greatest yield in chickpeas grown on an acid soil, however multiple factors may need to be addressed to capture yield benefits
