This trial aims to determine the suitability of the species and varieties to the region. Nitrogen (100kg N/ha, as urea) was applied early post emergent to CBA Captain chickpeas and PBA Butler field peas to determine how
background soil nitrogen levels influence pulse nitrogen fixation.
Key findings
Chickpeas
• There were only small differences in grain yield between the chickpea
varieties with CBA CaptainA and PBA SlasherA the highest at 1.7 t/ha, and
PBA HatTrickA and PBA SeamerA the lowest at 1.5 t/ha.
• CBA CaptainA produced the largest seed (24.2 g/100 seeds), while
PBA HatTrickA and PBA SlasherA had the smallest (22.4 g/100 seeds).
• The application of nitrogen (N) early post-emergent (100 kg N/ha as
urea) did not increase grain yield of CBA CaptainA but did increase peak
biomass from 6.4 to 7.3 t/ha, and seed N concentration from 3.5 to 3.8%.
Field peas
• APB BondiA was the highest yielding variety at 1.9 t/ha and SturtA the
lowest at 1.1 t/ha.
• Seed size was correlated to grain yield, with APB BondiA the largest
(17.6 g/100 seeds) and SturtA the smallest (15.2 g/100 seeds).
• The application of N early post-emergent (100 kg N/ha as urea) to
PBA ButlerA did not increase grain yield, peak biomass nor seed N
concentration.
