Mungbean variety comparison – Liverpool Plains 2013–14

Abstract

Key findings • Jade‑AU [PBR] released in 2013, has demonstrated equal or significant improvements over the now outclassed Crystal [PBR] in areas of yield, seed size and plant architectural attributes in this experiment. • Celera II‑AU [PBR] released in 2014 has extended the range of varietal maturities available, being the quickest to flower and reach physiological maturity. Practical management considerations in this experiment resulted in a long delay to harvest. This impacted negatively on yield performance and does not represent a true indication of its yield potential. • Differences in yield were established between varieties, however results should be treated with caution due to a coefficient of variation of 21% in this trial. • Biomass production is central to nitrogen fixation and is integral to quantifying the contribution of summer pulse crops to northern farming systems over the longer term. These experimental results contribute to a collaborative relationship with the GRDC funded Project DAQ00181: Optimising nitrogen fixation in grain legumes – northern region, led by Dr Nikki Seymour at DAFF in Queensland.
