Nodulation studies with pulses on acidic red-brown soils – Wagga Wagga 2014

Abstract

Key findings »» Chickpea and lupin failed to nodulate without inoculation. »» Inoculation formula had minimal effects on growth and yield of pulses at this site. »» Peat and liquid formulations were consistently reliable inoculants across all pulses based on nodulation and grain yield. »» Differences measured in nodulation were not reflected in differences measured in crop growth and grain yield, suggesting soil nitrogen reserves were sufficient to make up most of the crop’s needs. »» Field pea and lentil rhizobia appear more widespread in this environment and better adapted to the acidic soils, while chickpea rhizobia appear less adapted.
